It takes tremendous amount of time for developers to setup the environment to fix a bug in an application. Depending upon the complexity of application, it may take a few days to several weeks for developer to replicate a production environment. Very few solutions exist today that help reduce that time. With the help of Amazon EC2 you can in theory set up instantaneous infrastructure through a bug tracking system (JIRA).For each application, the developers usually need a machine for the old platform on which the bug exists, and a separate machine to install the new environment, which has the bug fix. In some situations, the QA environment could need a separate machine for all the testing. If the total number of applications increases to say 40, then this leads to a maintenance nightmare, and the whole solution would be really expensive. The solution will consist of extending an issue tracking system to capture the configuration of a specific environment through a plugin and automatic installation and configuration of a system through templating of a system.
