Develop and Deploy Multi-Tenant Web-delivered Solutions Using IBM Middleware: Part 5: A mediation approach for multi-tenancy and three implementation options
Part 1 of this series described multi-tenancy in a web-delivered business solution (a.k.a Software-as-a-Service) and Part 2 discussed the three different approaches for enabling multi-tenancy. In this article, we focus on the mediation approach for multi-tenancy first introduced in Part 2. We present three implementation options for this approach using different IBM middleware products and compare the relative benefits. The detailed implementation steps for each option will be described in the following three tutorials. 		Articles 01 Jun 2009  
 
Develop and Deploy Multi-Tenant Web-delivered Solutions Using IBM Middleware: Part 7: A Web service mediation proxy pattern for routing multiple tenant requests using WebSphere Enterprise Service Bus
Part 1 of this series describes multi-tenancy and several technical challenges faced by service providers for deploying multi-tenant web-delivered solutions. In part 4, we presented a technical challenge on how to enable multi-tenancy for existing single tenant Web services with little or no code changes for shorter time to market and lower costs. We presented a mediation approach for addressing this challenge and introduced three implementation options using multiple IBM middleware products. In this tutorial, we describe detailed implementation steps for utilizing WebSphere Enterprise Services Bus for enabling multi-tenancy for existing Web services. 		Tutorial 29 Jul 2009  
 
Develop and Deploy Multi-Tenant Web-delivered Solutions Using IBM Middleware: Part 8: A Web service mediation proxy pattern for routing of multiple tenant requests using WebSphere DataPower SOA appliance
Part 1 of this series describes multi-tenancy and several technical challenges faced by service providers for deploying multi-tenant web-delivered solutions. In part 4, we presented a technical challenge on how to enable multi-tenancy for existing single tenant web services with little or no code changes for shorter time to market and lower costs. In this tutorial we will present detailed implementations steps using a WebSphere DataPower SOA appliance in combination with Tivoli Access Manager. 		Tutorial 10 Aug 2009  
 
Develop and Deploy Multi-Tenant Web-delivered Solutions using IBM middleware: Part 2: Approaches for enabling multi-tenancy
Part 1 of this series describes what multi-tenancy is and presents several technical challenges for building and deploying multi-tenant web-delivered solutions. In this article, we identify five representative approaches for enabling multi-tenancy in web-delivered solutions (also known as software-as-a-service) and compare their costs and benefits.

Develop and Deploy Multi-Tenant Web-delivered Solutions using IBM middleware: Part 4: Design patterns for sharing resources in single instance multi-tenant applications
This article is the fourth in a series which addresses how to develop cost effective, secure and configurable Web deliverable applications by leveraging the multi-tenancy model. This model enables a single, shared application instance with the capability to support multiple client organizations (or tenants) simultaneously, so as to achieve the goal of cost effectiveness through sharing infrastructure and operation resource among tenants.

Develop and Deploy Multi-Tenant Web-delivered Solutions using IBM middleware: Part 3: Resource sharing, isolation and customization in the single instance multi-tenant application
This article focuses on the single shared application instance based on the multi-tenancy enablement model. It introduces the multi-tenant resources sharing, isolation and customization mechanisms of those important J2EE artifacts in such patterns. It also leverages a sample application to illustrate how to design a multi-tenant enabled J2EE application base on IBM middleware software. 		Articles 11 Mar 2009

Develop and Deploy Multi-Tenant Web-delivered Solutions Using IBM Middleware: Part 6: Web service mediation proxy pattern for routing multiple tenant requests using WebSphere Business Services Fabric
Part 1 of this series describes multi-tenancy and several technical challenges faced by service providers for deploying multi-tenant web-delivered solutions. In part 5, we presented a mediation approach for addressing this challenge and introduced three implementation options using multiple IBM middleware products. In this tutorial, we describe detailed implementation steps for one of those three options i.e. how to use WebSphere Business Services Fabric in the context of a example multi-tenant banking application scenario also introduced in part 5.

Develop and Deploy Multi-Tenant 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 scalable, configurable, and cost-effective multitenant Web-delivered solutions. 		Articles 24 Apr 2008
