With JRebel, developers get to see their code changes immediately, fine-tune their code with incremental changes, debug, explore and deploy their code with ease (both locally and remotely), and ultimately spend more time coding instead of waiting for the dreaded application redeploy to finish.
Every time a developer tests a code change it takes minutes to build and deploy the application. JRebel keeps the app server running at all times, so testing is instantaneous and interactive.
Today's competitive marketplace requires the organization to frequently release and deploy applications at the pace of user demands, with reduced cost, risk, and increased quality. This book defines the basics of application release and deployment, and provides best practices for implementation with resources for a deeper dive.
Inside you will find:
The business and technical drivers behind automated application release and deployment.
Evaluation guides for application release and deployment solutions.
