For those of you basically familiar with IBM Workload Deployer, you are likely aware that the appliance has many different capabilities. On the surface it is a cloud management device for middleware and middleware applications. Of course, there are quite a few details that are important to understanding the functionality provided, and I spend quite a bit of my time talking with various users and potential users about these details. One thing I have noticed that can become an obstacle in having effective communication regarding IBM Workload Deployer is the lack of a commonly understood language. I sometimes find that me and the user are simply using different terminology to describe the same thing. As you can imagine, this just serves to create confusion, and neither party gets the most out of the conversation.
In order to combat this communication gap, I thought I would put together a simple presentation that introduces and defines IBM Workload Deployer terminology. Check it out below (you can also download it here):
While the presentation does not dive deep into the terms it introduces, it does provide a basic definition and illustrative example of each. My hope is that this fosters an understanding of some of the basic concepts in IBM Workload Deployer, and ultimately pushes us towards a common vernacular. Please let me know what you think!
If you follow this blog often, you know that from time to time I like to post frequently asked questions. Well, it's been a while since I have done that, and since then I have added some new questions to my list -- along with some regulars. Take a look below, and if I don't answer your question feel free to leave a comment!
Can IBM Workload Deployer deploy software that is not IBM software? Yes. You can use one of the included images as a springboard and customize them with your own software via extend and capture. Additionally, you can use the IBM Image Construction and Composition Tool (I'm getting ahead of myself here) to create your own custom images from the ground up and use those within IBM Workload Deployer.
Can I use VMotion for the systems I deploy with IBM Workload Deployer? Yes. IBM Workload Deployer has tolerated the use of VMotion since the WebSphere CloudBurst days (see the Additional Considerations section on this page for more information). IBM Workload Deployer v3 introduced the notion of virtual machine mobility initiated directly from the appliance. This capability takes advantage of VMotion in the case of VMware-based cloud environments.
Can IBM Workload Deployer deploy just a base operating system? Yes. IBM Workload Deployer v3 introduced a base operating system image that contains 64-bit Red Hat Enterprise Linux. Internally, IBM Workload Deployer uses this as the foundation on top of which virtual application patterns are deployed. You can use it to deploy virtual machines containing just the base OS, or you can customize it to deploy software of your choosing. (As an aside, IBM Workload Deployer v3.1 will include a base operating system image for AIX)
Can I automate the process of calling/using IBM Workload Deployer? Yes. IBM Workload Deployer is built to fit a specific need -- creating and managing a cloud of middleware and middleware-based workloads. In that light, it would be a shortcoming if IBM Workload Deployer did not to fit well into more holistic or enterprise-wide cloud management systems. The REST API and CLI allow you to automate the use of IBM Workload Deployer, thereby allowing it to be mashed up into other processes.
Can I group two appliances together for high availability? Yes. IBM Workload Deployer v3.1 introduces the ability to configure appliances in a master/slave setup. You can connect two appliances, allow them to share a floating IP address, and be confident that data is continuously replicated between the two. If one appliance fails, the other appliance picks up the floating IP ensuring continuous service.
Are images created using the Image Construction and Composition Tool supported for use within IBM Workload Deployer? Yes. Part of the new IBM Workload Deployer 3.1 announcement was a statement of support for using images created by the Image Construction and Composition Tool as a component of your virtual system patterns. This is a very important enhancement as it allows you to extend the set of content deployed by IBM Workload Deployer while being sure that you are operating within the boundaries of intended use.
Can I use IBM Workload Deployer to provision to public clouds? No... and yes. If you install an IBM Workload Deployer appliance in your datacenter, you cannot use it to deploy to a public cloud environment. However, you may have recently heard about the IBM SmartCloud Application Services portfolio. IBM has announced that the pattern-based provisioning that one gets with IBM Workload Deployer will also be available as part of this portfolio. This means that you will be able to build and deploy patterns using a service hosted on the IBM SmartCloud. Further, your deployed systems will run on the IBM SmartCloud. Check out this demo for more information.
** IBM Workload Deployer 3.1 firmware is available on 11/18.
IBM Workload Deployer v3.1 firmware has been released and is available for download. V3.1 includes many improvements, building upon the solid foundation that was laid in V3.0 and earlier releases of WCA. There are many improvements and enhanced features. Dustin already alluded to a few of these in his previous post but let me list again here some of the more prominent new features:
The ground breaking capabilities offered in our Virtual Application Patterns have been extended to include deployments for AIX on PowerVM - giving you more choices for your private cloud environment. Along with this support a new base operating system image for AIX is also available for extension using either extend and capture or the IBM Image Construction and Composition Tool. Of course, Virtual System Patterns continue to be supported on all three private cloud hypervisors we support: VMWare, PowerVM, and zVM.
A new version of the Web Application Pattern Type (formerly WebApp Pattern Type) has been released. The Web Application Pattern Type V2.0 is built upon the feature rich WebSphere Application Server V8.0 release.
The DBaaS Pattern Type has been updated and is now the IBM Database Patterns 1.1 which includes both the IBM Data Mart Pattern 1.1 and the IBM Transactional Database Pattern 1.1 (OLTP - the default). These pattern types support a broader range of offerings for both production and non-production use. You can choose to create a new type of workload standard to apply to the DB instance or you can choose to clone an existing DB image that has been backed up to your DB image catalog repository.
A number of improvements have been made to the shared services leveraged by Virtual Application patterns. The caching service used to persist session data when scaling a web application can itself now be configured to scale, adjusting to increased demand. We have also extended the shared services to support external caching services and to leverage an external monitoring service based upon Tivoli Enterprise Monitoring Server (TEMS). You can also deploy multiple instances of shared services by deploying to multiple cloud groups.
The Plugin Developer Kit that was previously released to support building your own plugins and pattern types for Virtual Application patterns is now available for download directly from the IBM Workload Deployer dashboard - making it even easier to gain access and experience using this extension mechanism to deliver your own custom plugins and pattern types.
Images created using the IBM Image Construction and Composition Tool are now fully supported in IBM Workload Deployer V3.1 Virtual System patterns. Furthermore, the IBM Image Construction and Composition Tool is now a generally available product that is fully supported and available for download directly from the IBM Workload Deployer dashboard.
Speaking of Virtual System Patterns - a new hypervisor edition image of WebSphere Application Server V8 is now delivered with the appliance. WebSphere Application Server V8 fully supports the JavaEE6 programming model and includes many other programming models directly in the base image that were previously delivered only as feature packs including OSGi, JPA, and many more.
One item already mentioned by Dustin is the ability to configure multiple IBM Workload Deployer appliances in a master/slave relationship with a floating IP address to support continuous availability in the event that the master become unavailable. This feature can also be leveraged to support continuous operation while performing maintenance.
Another key appliance improvement is increased appliance security through the introduction of several new security roles for separation of duties. This is to ensure that no single user has unrestricted control without oversight. Among the new roles is an auditing role and auditing operations to provide data for forensic analysis of security attacks and better assist with compliance with the Health Insurance Portability and Accountability Act (HIPAA) and the Sarbanes Oxley Act (SOX).
We believe that these new features and several more make the value proposition delivered by IBM Workload Deployer V3.1 an even more compelling offering that can increase agility, consistency, and time to value for your applications. You can download IBM Workload Deployer V3.1 from IBM Fix Central. Please let us know what you think!
In a recent post, Joe Bohn detailed some of the new capabilities and enhancements that come along with the recently delivered IBM Workload Deployer v3.1. To be sure, there are many valuable new features such as PowerVM support for virtual application patterns, the Plugin Developer Kit, WebSphere Application Server Hypervisor Edition v8, and more. Each of these topics probably merit their own post, but today I want to talk about something I did not mention above. Specifically, I want to talk about the announcements regarding the IBM Image Construction and Composition Tool (ICCT) and what that means for IBM Workload Deployer users.
You may have read an earlier post that I wrote about the ICCT, but allow me a brief overview here. In short, the ICCT enables the construction of custom virtual images for use in IBM Workload Deployer. You use the tool to create virtual images, much like IBM Hypervisor Edition images, and then you can use those custom images (containing whatever content you need) to create your own custom virtual system patterns. The key point about the custom images you create with the ICCT is that they are dynamically configurable. That is, the tool helps you to create the images in such a way that you can defer configuration until deploy time rather than burning such configuration directly into an image. For those of you familiar with virtual image creation, you know this type of 'intelligent construction' is a huge step towards keeping image inventory at a reasonable level.
Okay, enough of a general overview for now. Let's talk about the two new items of note regarding IBM Workload Deployer v3.1 and the ICCT. The first thing you should know is that starting in IBM Workload Deployer v3.1, the ICCT is shipped with the appliance. This means that you do not need to go anywhere else in order to get your hands on the tool to start creating your custom images. You simply log into IBM Workload Deployer and click the download link on the appliance's welcome panel (shown in image below).
Getting your hands on the tool is one piece of the puzzle, but using it is quite another. While the ICCT has been available as an alphaWorks project for some time, that also implies that there has never been official support for the tool. That changes starting with IBM Workload Deployer v3.1. The ICCT is now a generally available product from IBM, and that means that it is fully and officially supported as well. Further, the images you create using the tool are also officially supported for use as building blocks of your IBM Workload Deployer virtual system patterns. For many of you who have been using the ICCT for some time, but have been hesitant to expand use because of the lack of a formal support statement, you should now feel free to charge forward!
I hope this helps clear up exactly what the new Image Construction and Composition Tool announcements that were part of IBM Workload Deployer v3.1 actually mean. I cannot wait to hear about how you all are putting the ICCT to use with IBM Workload Deployer. Finally, don't forget to send us any questions, comments, or other feedback that you may have regarding this or any other new feature in IBM Workload Deployer v3.1!
When IBM Workload Deployer v3.0 rolled around, the appliance introduced the concept of shared services. These were services that a cloud administrator could launch into the cloud infrastructure defined to IBM Workload Deployer, and use to serve a number of different application deployments. There were, and continue to be, two main shared services: a proxy service and a cache service. The shared proxy service does pretty much what you may guess. It provides request routing capabilities across multiple different instances of multiple different applications, thereby providing a centralized resource that encapsulates this basic need in an application environment. You can probably also guess what the caching service does. It caches things! Specifically, in IBM Workload Deployer v3.0 it provided in-memory caching of HTTP sessions, thus ensuring high availability of data stored in those sessions.
Undoubtedly, the ability to make HTTP session data fault tolerant is extremely critical in any application environment, cloud-based environments included. However, the applicability of a shared cache service is much further reaching, and in IBM Workload Deployer v3.1, we are starting to open this service up to your applications. What does this mean to you? Quite simply it now means that you can access this cache directly from your application code. If you are familiar with WebSphere eXtreme Scale or the DataPower XC10 Caching Appliance, then you know exactly what I mean. You can use the WebSphere eXtreme Scale ObjectGrid API to insert, read, update, and delete entries that exist in the in-memory cache. The underlying cache technology is based on the same code that powers WebSphere eXtreme Scale and DataPower XC10, so you can be sure that your cache is scalable, fault tolerant, responsive, and otherwise able to meet the needs of your application.
As I hope you find to be the case with many IBM Workload Deployer capabilities, this is a superbly simple capability to leverage. When you deploy virtual application patterns based on the IBM Workload Deployer Pattern for Web Applications, the capability is simply there. The underlying runtime that is serving your application is automatically augmented with the capabilities necessary so that your applications can connect to and utilize the deployed caching service. It is also worth pointing out that you can utilize the caching capabilities provided by this shared service for applications and application infrastructure that you deploy via virtual system patterns as well. You can either choose to augment the WebSphere Application Server environment with the XC10 Feature Pack (a deploy-time option for virtual system patterns built on WebSphere Application Server Hypervisor Edition v8), or you can configure WebSphere Application Server as you always would when integrating with a WebSphere eXtreme Scale environment or a DataPower XC10 Appliance.
What's the real benefit to all of this you ask? Well, when you use the shared caching service, you get the benefits of a distributed, in-memory, extremely scalable cache without having to deal with too much setup or administration. You simply tell IBM Workload Deployer how many resources you want to dedicate to your cache, and deploy the shared service. IBM Workload Deployer takes care of the details, including scaling in and out the cache to meet the needs of the system. On top of all of this, there is also an option to configure 'Next to the Cloud' caching. If you currently own DataPower XC10 appliances, you can make those available to virtual application pattern deployments (this was already possible with virtual system patterns) by simply providing details of the location of the appliance collective in question.
Put simply, setting up, administering, and utilizing an object caching service for your applications has never been easier. Check it out and let us know what you think!
Lately Joe and I have been pretty vocal about bringing up the new IBM Image Construction and Composition Tool capabilities in IBM Workload Deployer v3.1. While writing about such new capabilities is always good, I think seeing is believing. In that light, I hope you will take a look at the recent demo I put together that shows how to use the Image Construction and Composition Tool with IBM Workload Deployer v3.1!
In the previous post Dustin shared a great video demonstrating the value of the IBM Image Construction and Composition Tool that is now delivered with IBM Workload Deployer V3.1. This is certainly one of the key new features of IBM Workload Deployer V3.1. However, there are also a number of other compelling enhancements and features that we would like communicate.
I created the attached video to highlight some of these features included in new Workload Deployer release. The video uses the web console to highlight some of the features and capabilities, giving a brief introduction for each one. Without going into a lot of depth, I think it gives a nice overview. This may be especially helpful if you already have Workload Deployer v3.0 and want to see the value you will get when you upgrade to Workload Deployer v3.1. Check it out.
We believe that these new features make IBM Workload Deployer V3.1 an even better solution for your private cloud needs. Please let us know what you think.
When IBM Workload Deployer V3.0 was introduced last year, one of the "hidden" values that it delivered was a base image used for virtual application patterns. I say "hidden" because this image, while delivered primarily for use in virtual application patterns, could also be leveraged for virtual system patterns. By now you may be scratching your head and wondering just what I'm talking about. Let me explain...
To begin with, it is helpful to understand a little bit about how virtual applications are deployed and how that differs from virtual system patterns. As you may already know, virtual system patterns are built from IBM Hypervisor Edition images to launch the virtual machines for your deployment. The IBM Hypervisor Edition images include the Operating System and middleware components together in the image. Therefore, building a virtual system pattern basically starts with a fairly complete image and activates the parts in that image necessary to fulfill the particular role this virtual machine will pay in a virtual system pattern. Virtual application patterns take a somewhat different approach. The starting point for a virtual application pattern is the base image which only includes the base Operating System. Workload Deployer launches a virtual machine with just this base image and then the appliance manages installation, configuration, and integration of software and applications to complete the role this virtual machine must fulfill for this virtual application pattern. At a high level you could consider virtual system patterns a template approach and virtual application patterns more of a build it as you need it approach.
So just what is the "hidden" value of these base images provided for virtual application patterns and how can that be used for virtual system patterns? The hidden value is that the base images used for virtual application patterns are delivered with IBM Workload Deployer in the image catalog and can be used for building virtual system patterns. If you already have an appliance you can take a look ... you will see the base images there under Catalog > Virtual Images right along side more familiar images like the IBM Hypervisor Edition images for WebSphere Application Server. For x86 systems this image is appropriately named "IBM Workload Deployer Image for x86 Systems". These images each include a base part called "Core OS" that can be included in a virtual system pattern.
So now you may be saying to yourself - well that's all great news but what is new about this? The new thing is that in IBM Workload Deployer V3.1 a significant new feature was added - the ability to deploy virtual application images to PowerVM environments using AIX. To enable that feature a base image was created for AIX, the "IBM OS Image for AIX Systems." As with the x86 image, this new image is now also available for your use in the image catalog. You can now employ that default AIX image for your own needs in virtual systems patterns - creating a very nice extension mechanism for PowerVM and AIX users.
This new base image contains the IBM AIX 6100-05 operating system and the Core OS part that you can include in virtual system patterns. As with the x86 base image delivered earlier, there are no restrictions on how you use or customize this image. To make it suitable for your purposes you can employ the IBM Workload Deployer extend and capture capability to install additional software content into the image. You can also enhance this image using the IBM Image Construction and Composition Tool (ICCT) that is now included with IBM Workload Deployer v3.1. When you include this part in a virtual system pattern you can also associate any configuration scripts that you may need, just as you would with any other part. Just as with the x86 part - this provides substantial value and a significant convenience for AIX users.
I hope this clues you in on the "hidden" benefits of a substantial new feature included in IBM Workload Deployer V3.1. We have often been asked to provide base OS images to build upon as starting from scratch is sometimes difficult when you need to create your own custom image. Now, with IBM Workload Deployer v3.1, you have your choice of two default images in addition to the many IBM Hypervisor Edition images delivered as well as a robust set of new features in IBM Workload Deployer V3.1!
In the previous post I spoke about how a Virtual Application feature introduced in Workload Deployer v3.1 actually had benefits for Virtual System patterns as well. In that case I was talking about the ability to deploy Virtual Applications running on AIX to PowerVM hypervisors and how this had hidden benefits for Virtual Systems as well. This is a great example of how an enhancement to Virtual Applications can sometimes benefit Virtual Systems. However, this is not the only instance where the two pattern types intersect.
Several other new or enhanced features that are primarily for Virtual Applications are also being extended to benefit and improve Virtual Systems ... and vice-versa. One such area of improvement involves Shared Service in v3.1. These services were introduced in v3.0 specifically for the benefit of Virtual Applications. However, several enhancements have extended these capabilities to Virtual Systems and likewise, some functionality that was previously only available to Virtual Systems has been extended to Virtual Applications in the form of Shared Services.
As you may already know, Shared Services were first introduced in v3.0 and are just what the name implies; services that are deployed by a cloud administrator and used by multiple virtual application deployments. Let's start by taking a look at the shared services available under Cloud -> Shared Services in v3.1. You will notice that there are now more shared services listed than there were in v3.0.
In addition to the familiar Caching Service and ELB Proxy Service (formerly Proxy Service) there are now additional entries for an External Caching Service and an External Application Monitoring Service. For simplicity let's just start from the top and go down the list, discussing the function of each service, what is new/improved for v3.1 with regard to virtual applications, and when applicable how this service can be used by virtual systems.
The Caching Service was introduced in v3.0. Its primary purpose is to cache HTTP session data using a highly scalable and fast in-memory cache. This is the same core technology that is included in our WebSphere eXtreme Scale and DataPower XC10 Caching appliance. To make use of this service all you need to do is deploy an instance of the Caching Service with the configuration parameters of your choice into a cloud group where you want to leverage that service. As you create virtual application patterns you simply select the Enable session caching check-box when you add a scaling policy. When this pattern is deployed it will be automatically configured to leverage the Caching Service for session persistence. It's as simple as that.
Several new features were introduced in v3.1 for the Caching Service. First, the Caching Service can now be launched with parameters to define the behavior for automatic scaling to meet the ever changing demands of your applications. Once set, Workload Deployer will manage this service to ensure sufficient capacity based upon your requirements, adding or removing containers. Second, and this is significant for Virtual System patterns, the caching service has been enhanced to add new operations to support listing, creating, and deleting various types of object grids. You can then use the WebSphere eXtreme Scale ObjectGrid APIs to persist and manage content in the grid from your application code from Virtual System deployments. This saves you the trouble of creating and configuring your own caching service for these purposes outside of the cloud and permits sharing of the service you have already configured - a nice savings.
Caching Service (External)
The External Caching Service is one of the new additions for v3.1. Let's say that you already have configured a caching solution for your enterprise using the DataPower XC10 appliance or a collective of appliances. It would be nice if you could leverage this same solution instead of launching yet another caching solution within your private cloud. Leveraging your existing solution would consolidate your caching needs and preserve the cloud resources for other purposes. With this new external caching service you can do just that. It provides you the ability to leverage an external caching solution for both your Virtual Application session persistence needs as well as your Virtual System and even non-cloud caching needs. Just point an instance of this external caching service at your DataPower XC10 caching solution and all of the HTTP session persistence needed by your virtual applications in the same cloud group will make use of the external caching service. You can also point multiple instances of the external caching service in multiple cloud groups to share the same XC10 appliance or collective.
Monitoring Application (External)
With the External Monitoring Application service you can deploy an External Application Monitoring service reference within a cloud group to point at a Tivoli Enterprise Monitoring Server installation outside of the cloud. The TEMS server must be at version 6.2.2 Fix Pack 5 or later. Once created, the Unix or Linux OS monitoring agents and the Workload monitoring agent that is provided for virtual application workloads will be automatically connected to the defined instance of the Tivoli server using the supplied primary and fail-over Tivoli Enterprise Management server, protocol, and port. This is especially useful if you want to consolidate all of your monitoring to a common console. As with the External Caching Solution, this enhancement also extends the integration capabilities of Virtual Application Patterns beyond the scope of your private cloud and allows you to consolidate and leverage investments you have already made.
ELB Proxy Service
The Proxy Service was first introduced in v3.0 and renamed to the ELB Proxy Service in v3.1 for clarity. As the name implies, its primary purpose is to provide routing and load balancing to multiple deployed web applications. As with the caching service, you deploy this service based upon your requirements for load and availability within a cloud group. When defining virtual application patterns to leverage this service you simply add a routing policy and define your virtual host name. When the virtual application pattern instance is deployed to the cloud group the necessary configuration will performed to add the virtual host name and configure your application environment to use the ELB Proxy Service. New in v3.1 is the capability to scale the ELB Proxy Service itself to meet the changing demands of your application mix.
One other item that I should point out (and to which I've already alluded) is that you can now deploy multiple instances of each of the shared services - one per cloud group. Shared services can also now be deployed using environment profiles. This was not previously the case in v3.0 where each service was a singleton for the appliance. Allowing multiple instances of shared services gives you the flexibility to configure the sharing of your services as necessary for your particular environment.
I hope this post has provided a useful overview of the value of shared services and the new capabilities introduced in v3.1. I also hope that you can see how these services make it easier to implement your solutions for both virtual applications and virtual systems within a private cloud environment and shed a little light on how we are continuing to improve IBM Workload Deployer. As always, these improvements are driven by the feedback we receive from you so please let us know what you think!
Everybody likes having choices. This is true whether you are talking about lunch or deploying to a private cloud. When IBM Workload Deployer v3.0 was first introduced it included a pattern type for our Database-as-a-Service offering. The DBaaS PatternType v1 provided substantial value in an easy to use form factor to get a database up and running quickly and then provided the necessary tools to manage that environment. Pretty impressive for a first release! But the story doesn't end there. IBM Workload Deployer v3.1 brings an updated version of this pattern type that builds upon this foundation and adds even more capabilities and more choices.
Some of you may not be familiar with the Workload Deployer Database-as-a-Service offering so let me give you a brief introduction. Database-as-a-Service patterns allow you to define and deploy database applications into your private cloud environment with speed and consistency. These offerings also provide integrated management and monitoring capabilities. The Database-as-a-Service capability can be used in conjunction with a web application pattern (Patterns -> Virtual Applications, IBM Web Application Pattern) by including a database component in a pattern connected the web application components to use it. In this case the web application and database are deployed and managed as a unified solution with a common life-cycle as shown in the pattern below.
Database patterns can also be created and deployed as standalone entities (Patterns -> Database Patterns) that have their own life-cycle, independent of the virtual web application(s) that use the database. What's more, you can leverage these stand-alone databases from applications both inside and outside your private cloud.
Whether you use a stand-alone database pattern or one that is part of a web application pattern, the attributes and capabilities of the database are consistent.
So what is new in this release? For starters, the DBaaS PatternType has been renamed and the capabilities expanded. For Workload Deployer v3.1 the pattern is delivered as the IBM Database Patterns v1.1 and includes several elements to provide predefined configurations: the IBM Transaction Database Pattern and the IBM Data Mart Pattern.
Before we take a closer look at the new features I just want to alert you to one thing. Before you can leverage any of these new features you first need to accept the licenses and configure the plugins for the database pattern types. So look at the link and follow the directions if you would like to along and you aren't seeing the same options in your IBM Workload Deployer V3.1 system.
Using the screen shot above as a reference, let's take a look at what you can specify when creating a database pattern. You start with a name for the pattern and an optional pattern description. You also specify the maximum user data space size and an optional schema file. These are pretty basic and were all available with in the previous release. Another really nice feature that has also been available since the first release is the ability to specify a compatibility mode for DB2 and Oracle (a nice feature if you are looking to move content from existing databases).
Some of the new enhancements appear in the middle of the view; the purpose and source. The purpose specifies if this database is to be used for production or non-production (test and development). Your selection will optimize license management for deployed instances of this pattern.
The source field lets you specify a database configuration to be used to provision this database. You can choose from two different provisioning approaches; applying a workload standard or cloning from a database image. When choosing apply a workload standard you select between two predefined, optimized database configurations. These configurations will run a set of scripts to tune the operating system and instance configuration for the database. The departmental transactional standard is optimized for online transaction processing applications while the data mart standard is optimized for data mining purposes and is therefore more suitable for reporting applications. If those aren't exactly what you want but you have an existing database you can use the clone from a database image approach by selecting an existing database image backup as a model for the new database pattern. When using the clone method metadata from the backup is retrieved and a DB2 restore command is used to set the same configuration for the new database instance. Reference the cloning from a database image topic in the IBM Database Patterns information center for more details.
Once the pattern has been created you can deploy the pattern to a target cloud group or an environment profile (another new feature for database deployments in IBM Workload Deployer V3.1).
I hope you can see the value that has been added with the source configuration choices and the ability to clone an existing configuration. They are certainly substantial new features of the Database-as-a-Service solution in Workload Deployer V3.1. However, there are a number of other significant enhancements that I would just like to mention as well. In other posts we've discussed the new ability to deploy virtual applications to run on AIX with a PowerVM hypervisor. As you might expect this same ability is also available to deploy database patterns to run on AIX systems leveraging PowerVM. Management capabilities have also been significantly enhanced with the ability to configure automated database backups using the IBM Tivoli Storage Manager. These features and many other aspect of the Database-as-a-Service model are detailed in the IBM Database Patterns information center and the IBM Workload Deployer information center. My goal here has not been to replicate our product documentation - it is rather my goal to provide a few highlights and provide pointers to help you get started. I hope it has been useful.
You can be sure that we will continue enhancing and improving our Database-as-a-Service offering in IBM Workload Deployer. Please provide your feedback so that we can make it even better.
