Web services security interoperability using Kerberos
XML Web services provide an open, standards-based mechanism for inter-process communication and are common in implementations of Service Oriented Architecture (SOA). From a security perspective, complementary standards such as WS-Security exist to enable cross-platform, cross-domain interoperability for message level security. Implementations using these standards often reveal subtle challenges. In this article, security interoperability using Kerberos security tokens in a heterogeneous Microsoft .NET and IBM WebSphere J2EE environment is examined. A number of non-obvious implementation details are provided to assist readers in implementing their own solutions.

Web service mediation patterns for dynamic routing of multiple tenant requests using WebSphere Business Services Fabric
Explore one of three IBM middleware based mediation patterns for rapid enablement of multi-tenancy for existing Web services implementations. The pattern in this demo uses WebSphere Business Services Fabric. The remaining two patterns show the use of WebSphere Enterprise Services Bus and WebSphere DataPower. In the demo, multi-tenancy is enabled for an existing single tenant credit check service by introducing a WebSphere Business Services Fabric based mediation pattern layer. This pattern layer uses a new TenantID assertion defined as an extension to the core WebSphere Business Services Fabric ontology. The assertion acts on properties defined in the Web services context to dynamically route credit check service requests from users for a particular tenant bank to service endpoints dedicated to that bank. The WebSphere Business Services Fabric subscription manager is used to enroll users and organization to the credit check service and the WebSphere Business Services Fabric performance manager is used to view service usage logs for each tenant.

Increase business agility through BRM systems and SOA
The widespread acceptance of Service-Oriented Architecture (SOA) proves that
enterprises have realized the promise of this technology. That promise of increased
agility comes from a basic software design principle: loose coupling. SOA allows for
business functions to be exposed as independent services. Web services, which is one
way to implement SOA, makes any business functionality available over the Internet.
Another technology that promises to extend that agility to business users is
business rules management (BRM) systems. A BRM system gives business users direct
control over the business logic, allowing them to change it without much
intervention from IT. This article explores how these two technologies--SOA and
BRM--promise to help businesses respond more quickly and cost effectively to
changing market conditions. |

Simplified tenant provisioning using IBM entry level middleware
This demo focuses on the ease of provisioning new tenant banks in a sample
banking application through the use of Apache ANT scripts and a few portlets for the
administrator roles. A new WebSphere Application Server Community Edition virtual
host and security realm are provisioned through ANT scripts invoked from a new
service provider administrator portlet. A new openLDAP user database is created and
new LDAP Data Interchange Format (LDIF) files imported through another ANT script. The portal for the new tenant bank is customized through a tenant administrator portlet by modifying style sheets, providing tenant specific images and uploading and deploying these to the running application. Custom fields are added to other portlets which use XML columns defined in DB2 Express-C V9 through simple configuration steps in a tenant administrator portlet.

Develop and deploy multitenant Web-delivered solutions using IBM
middleware, Part 1: Challenges and architectural patterns
Web-delivered solutions that follow a Software as a Service (SaaS) delivery
model -- where customers subscribe to software and access it from a service provider
site rather than get licenses and have software installed on their premises -- can
offer compelling business value for businesses of any size. Solution developers who
develop new solutions or transform existing solutions and service providers who
deploy these solutions are faced with several technical challenges. One example is
multitenancy, where a single instance of the software, running on a service
provider's premises, serves multiple organizations. This article series describes
different patterns to address these challenges, often using Service-Oriented
Architecture (SOA) techniques. Also learn how IBM software
products can help you build and deploy

Comment lines: Andre Tost: Visualizing SOA, from the first step to Second Life
Those of us involved in SOA projects are constantly looking to find appropriate ways to visualize aspects of the systems we are developing, from component maps and business models to patterns and flows, and even monitoring dashboards. But much of this information is static, and all of it is two-dimentional. New technologies present the possibility of dynamic and three-dimentional views that could enable us to not only observe a system in a virtual world, but also to interact with it so that our actions are applied to the real system.

IBM SOA Foundation product integration: Using WebSphere Transformation Extender with IBM Enterprise Service Bus products
The transformation to a service-oriented architecture (SOA) includes aspects that cover the entire lifecycle of a solution, from inception, to design and development, to its ultimate deployment and management. IBM published an SOA Reference Architecture that helps structure and position these aspects into a number of different components, and the IBM SOA Foundation includes a set of products that address specific components within the overall architecture. This article is the first of several that will discuss how products that are part of the IBM SOA Foundation can be used together. First up: how to add advanced transformation capabilities to IBM's set of Enterprise Service Bus (ESB) products: WebSphere Message Broker, WebSphere ESB, and WebSphere DataPower.

Transformation to SOA: Part 4. How Web service processes transform from UML to BPEL in IBM Rational Software Architect
The article explains how to model BPEL process implementation details in
UML. The Unified Modeling Language (UML) provides convenient, well-understood,
well-documented, and commonly practiced support for use case, collaboration, data,
interface, class, component, interaction, state, and activity modeling. You can
exploit this to capture application models that can be transformed to various
platform architectures. The transformation from UML to Process Execution Language
(UML-to-BPEL) that this article describes translates UML artifacts into BPEL
artifacts. |
