Over the past several months industry focus on cloud computing seems to have only intensified. Within IBM and for the purposes of this blog, WebSphere, there have been several announcements and offerings that indicate our commitment and belief in the cloud computing approach.
To further highlight WebSphere's focus and offerings in the cloud computing realm, we are embarking on a "WebSphere in the Clouds" campaign during the months of September and October. Our intent is to virtually deliver information about our cloud strategy and offerings directly from the experts to you, our WebSphere users.
The event will be kicked off by WebSphere's Director of Product Management, Kareem Yusuf, on September 23rd from 9-10 EDT. Kareem will talk about cloud computing in the enterprise, and its unique relationship to SOA thoughts and principles. In addition, he'll give an overview of what WebSphere has been doing in the cloud computing space. This will be followed by sessions from technical experts that detail WebSphere offerings in both the public and private clouds, as well as sessions that discuss enablers of application and application infrastructure elasticity.
To find out more about the "WebSphere in the Clouds" campaign, you can check out the main announcement page. To sign up for the series of virtual events visit the registration page. We hope you will join us for the series of webcasts to learn all about WebSphere's work in the clouds.
I've blogged previously about some of IBM's work in the public cloud and specifically on our partnership with Amazon to deliver IBM offerings on the Amazon EC2 cloud. Mostly on this blog I've been focused on IBM WebSphere offerings on the Amazon cloud, but coming up on October 1st, you'll get a chance to hear about and see the full breadth of IBM software offerings available on the Amazon EC2 cloud. Better than simply hearing and seeing, by attending the virtual developer's day, you'll get access to try out some of this software absolutely free!
By leveraging IBM software on Amazon EC2, users can very quickly benefit from the advantages of a cloud computing approach to IT. Instead of focusing valuable time and resource on installing, updating, and otherwise maintaining software, users can simply activate instances of the IBM software of their choosing on Amazon's infrastructure. Besides delivering this rapid approach to getting up and going, users can also leverage cloud computing techniques to quickly and dynamically scale up and down their entire application infrastructure. This ability to dynamically scale up and down means your end-users will always enjoy a satisfactory experience when accessing your applications on the cloud.
You can sign up for the Cloud Computing for Developers day here. In the meantime you can learn more about IBM offerings on the Amazon EC2 cloud by visiting the IBM/Amazon EC2 landing page. I hope you can take advantage of a chance to hear both IBM and Amazon experts and learn how IBM software delivered on the Amazon EC2 cloud can make a real difference for your business.
There have been quite a few announcements from IBM lately that keep referring to the "IBM Cloud". Since IBM has been moving at a pretty substantial pace with cloud offerings as of late, I thought it may help to give readers a concise idea of exactly what the IBM Cloud provides.
Put very simply, the IBM Cloud is a public cloud offering that allows users to provision and utilize IBM Software on an infrastructure hosted by IBM. From the IBM Cloud's web-based dashboard, users choose a software package, provide some deployment information about the particular instance they wish to create, and then simply click OK. In a matter of minutes the software is up, running, and available for full use. At the time I wrote this blog, I saw software from our Information Management, Rational, and WebSphere brands available for use. In addition, users can launch plain SUSE Linux instances out onto the IBM Cloud.
Within WebSphere, users can choose from either the WebSphere Application Server or WebSphere sMash. I just went through a WebSphere sMash deployment, and in about 6 minutes the sMash instance was up and running, and I was able to log into the App Builder development environment. The WebSphere Application Server package that's available on the IBM Cloud is particularly interesting because it contains an embedded Rational Controller Agent. This makes it very easy to integrate some of the Rational offerings on the IBM Cloud (or elsewhere) with the WebSphere Application Server. Many of these integration scenarios focus on making it easier to very quickly build, package, and deploy applications from Rational development tooling to WebSphere Application Server environments.
The best thing about the IBM Cloud is that you can sign up and give it a whirl with absolutely no costs! Go and sign up for a free account and you'll immediately be able to spin up IBM Software in IBM's cloud. You can access and use that software, and then when you are done you can simply delete the running instance. There's no need to download anything to your computer, the interface to the IBM Cloud is completely web-based, and the launched software runs on IBM infrastructure. All of this adds up to give users a super easy way to kick the tires on some of our software. Sign up now by visiting the landing page for the IBM Cloud.
The majority of my posts on this blog address using various features of WebSphere CloudBurst to build private cloud computing environments. Today though, I want to switch gears and instead of talking private cloud, let's talk public cloud. Specifically, let's take a look at the capabilities and services delivered via the IBM Smart Business Development and Test on the IBM Cloud (hereafter referred to as the IBM Cloud).
For some of you, the fact that IBM has a public cloud offering may be a little surprising. After all, if you listen to some uninformed critics you may hear that IBM only cares about private clouds for large enterprises. That is simply untrue. The IBM Cloud is an Infrastructure as a Service public cloud that delivers rapid access to services hosted on IBM infrastructure via a self-service web portal. The IBM Cloud offers multiple payment options, including usage-based billing and reserved capacity billing, and even features a cost estimator so you can confidently establish a monthly budget for your usage.
Regardless of whether you use a private or a public cloud, security should always be a chief concern. As such, IBM takes security very seriously in the IBM Public Cloud. The infrastructure that constitutes the cloud is subject to internal IBM security policies that include regular security scans and tight administrative governance. Your data and virtual machines stay in the data center to which you provisioned them, and physical security policies match those of internal IBM data centers. Additionally, you can optionally make use of the virtual private network option to isolate access to the virtual machines that you provision on the IBM Cloud. Rest assured that security in the IBM Cloud was a guiding design principle and not an afterthought.
With the basics out of the way, let's get on to the question I'm sure you have: What can I run on the IBM Cloud? To get you started, the IBM Cloud provides a nice list of public images in its catalog that are ready for you to provision. These images include WebSphere Application Server, WebSphere sMash, DB2, WebSphere Portal Server, IBM Cognos Business Intelligence, Tivoli Monitoring, Rational Build Forge, and many more. In addition to the public images provided by the IBM Cloud, you can build your own private images. Private images allow you to start with a base public image and then customize it by adjusting the configuration or installing new software. Once customized, you can store these private images on the IBM Cloud and provision them whenever needed. Whether you are using public or private images, you have a number of server configurations to choose from in order to host your environments.
While very brief, I hope this overview provides you with some of the more important details regarding the IBM Cloud. There are few, if any, service providers out there with the enterprise expertise of IBM, and I think you see that reflected in the IBM Cloud. If you are looking at public cloud options for your enterprise application environments, you should definitely take a closer look at the IBM Cloud.
When I talk with WebSphere CloudBurst users, the topic of custom virtual images comes up frequently. In some cases they simply want to customize a shipped IBM Hypervisor Edition, and in other cases they want to create a completely custom image. Creating a customized version of an IBM Hypervisor Edition is relatively easy since we give you extend & capture in WebSphere CloudBurst. Creating a completely custom image has historically been a bit tougher, mostly owing ot the fact that there was not a standard tool or process for image assembly. I am happy to say that today's publication of the IBM Image Construction and Composition Tool changes all that.
Watch a demo of the IBM Image Construction and Composition Tool
The primary purpose of the Image Construction and Composition Tool is to enable a modular approach to virtual image construction, while taking into account the typical division of responsibilities within an organization. The tool allows the right people within an organization to contribute their specialized knowledge as appropriate to the virtual image creation process. This means OS teams can handle the OS and software teams can handle the appropriate software. A separate image builder can then use both OS and software components to meet the needs of users within the organization. Best of all, the image builder does not need intimate knowledge of how to install or configure any of the components in the image. They simply need to know which OS and software components to use.
When using the Image Construction and Composition Tool, you start by defining the base operating system you wish to use for your images. You can do this by importing an existing virtual image with an OS already installed, providing an ISO for the OS, or pointing to a base OS image on the IBM Cloud. The bottom line is that you have necessary flexibility to start with your certified or ‘golden’ operating system build. Once you have the base OS image defined in the Image Construction and Composition Tool, you can start defining custom software for use in the images you will compose.
In the tool, bundles represent the software you wish to install within a virtual image. The definition of a bundle contains two major parts: Installation and Configuration. The installation component of a bundle tells the Image Construction and Composition Tool how to install your software into the virtual image. You provide a script or set of scripts that install the necessary components into your image, and you direct the tool to call these scripts. These tasks run once during the initial creation of the virtual image, thus allowing you to capture large binaries, long-running installation tasks, or other necessary actions directly into your image.
The configuration section of a bundle defines actions that configure the software installed into the image. Like with the installation tasks, you provide a script or set of scripts for configuration tasks. Unlike installation tasks that run exactly once, configuration scripts become part of the image’s activation framework and as such, run during each image deployment. Using the tool, you can define input parameters for configuration scripts and optionally expose them so that users can provide values for the parameters at image deploy-time. Configuration tasks are important in providing flexibility that allows users to leverage a single virtual image for a number of different deployment scenarios.
Once you have your base OS image and one or more bundles defined in the Image Construction and Composition Tool, you can compose a virtual image. To compose a virtual image, you extend the base OS image and add any number of bundles into the new image. A base OS image plus a set of bundles defines a unique image.
After you define the image you want to construct, you initiate a synchronize action in the Image Construction and Composition Tool. When you start the synchronize action, the tool first creates a virtual machine in either a VMware or IBM Cloud environment (based on how you configured the tool). Next, the installation tasks of each bundle you included in the virtual image run to install the required software. Finally, the tool copies the configuration scripts from each bundle into the virtual machine and adds them to the image’s activation framework. This ensures the automatic invocation of all configuration scripts during subsequent image deployments.
Once the image is in the synchronized state, you can capture it. Capturing the image results in the creation of a virtual image based on the state of the synchronized virtual machine. The tool also automates the generation of metadata that becomes part of the virtual image package. When the capture of the virtual image completes, you can export it from the Image Construction and Composition Tool and deploy it using WebSphere CloudBurst, Tivoli Provisioning Manager, or the IBM Cloud.
I am excited for users to get their hands on the Image Construction and Composition Tool. I believe it represents the first big step in helping users to design and construct more sustainable virtual images. Did I mention it is completely free to download and use? Visit the Image Construction and Composition Tool website for more details and a download link. I look forward to your comments and feedback.
