IBM® Tivoli® Service Automation Manager (TSAM) 7.2.2 introduces the concept of extension, a set of TSAM software components that can implement a new IT service automation solution (known as a service definition) or add capabilities to existing service definitions.
This article (Deploy a J2EE app with TSAM extensions) defines a scenario in which the desired result is to securely deploy a three-tiered enterprise application (a J2EE app) to the cloud. It demonstrates how to set up and provision extensions in TSAM as the first step to accomplishing this task. Then it describes how to standardize the three-tiered business application and provision it using standard TSAM offerings.
The second part of the article (Manage a J2EE app with TSAM extensions) focuses on the management aspects of the J2EE app. The authors explain how to add and remove application servers as the workload of the business application changes; and how to modify the security settings and why you might need to do that.

IBM® Tivoli® Service Automation Manager - Extension for Juniper SRX Firewall, and,
IBM® Tivoli® Service Automation Manager - Extension for F5 BIG-IP Load Balancer
These network extensions deliver out-of-the-box automation in infrastructure cloud services for configuring security access (Firewall) and scalability and redundancy (Load Balancer).
This extension enables customers to configure network security settings automatically when a project is provisioned, and manage security configuration over the lifetime of the project. Through use of security zones and traffic management policies all virtual networks resources are secured and access to applications and VMs within a project is customizable throughout the project life cycle.
A Juniper SRX Firewall implementation was chosen because of its large diffusion among service providers who are either using or evaluating IBM Tivoli Service Automation Manager.
The Juniper SRX Firewall extension provides the following functionality:
The screenshot below shows a typical firewall setup.
IBM Tivoli Service Automation Manager - Extension for F5 BIG-IP Load Balancer
Load balancing is one of the key values of any cloud project. The load balancer extension enables the definition of rules to automatically distribute the workload amongst VMs in the project whilst providing a single entry point (Virtual-IP) to external users (i.e. it presents itself as a single powerful machine to the user).
The BIG-IP Local Traffic Manager is the F5 product that performs load balancing across servers in a single data center providing intelligent load balancing and traffic management as well as advanced application security, acceleration, and optimization.
The F5 BIG-IP Load Balancer extension provides the following functionality:
The screenshot below shows one of the load balancer setup screens.
These extensions can be leveraged and verified through testing with other Juniper and F5 devices (with the same use cases). If you have other devices and/or other use cases you may wish to create your own custom extension by using these extensions as a starting point or example.
The diagram below gives and overview of the extension plug-points.
