Application Lifecycle Management (ALM) Community

(

http://bit.ly/IBMALM

)

Establish ALM community as YOUR community where you can find useful and usable

information and make it the most desirable community to became its member

Place to discuss ideas and issues in ALM that go beyond the tools, as well as follow trends that affect the software lifecycle emerging from many disciplines

By forming this community on developerWorks, we are able to tap into a talented network of practitioners and enthusiasts from not only software development and delivery, but cloud, big data, agile, mobile, middleware, etc.

To become a member and share information about ALM community read Welcome to ALM Community blog

Members gets notification when useful information is available Send feedback and suggestion here

surface?

“In practice, integration has proven to be the most enlightening activity in

exposing the risks and uncertainties in software development.”**

Test my own piece

• Integration Testing requires components that may not be ready/available yet, or expensive to use - Test Virtualization enables replacing them with a virtual component.

• Services, applications, systems are introduced into the continuous integration cycle in a prioritized, controlled fashion.

Example:

• Test C1 with three virtualized services.

• Can use simple or complex integration scenarios.

• Quick to setup and low-cost.
