PRODUCTION REDEPLOYMENT THROUGH APPLICATION VERSIONING

摘要

In one embodiment, application versioning and production redeployment support is designed to handle application upgrade needs in mission-critical, production environments. With multiple application versions, application availability to both existing and new clients is not interrupted during the process of application upgrade. It also provides the ability to test a new application version before opening it to general public as well as the ability to roll back to previous safe versions if there are any errors in the currently active version. Clients see consistent application versions, irrespective and transparent of all failure conditions, including admin or managed server restarts and/or failover. Administrators can monitor and manage application versions easily with the management Console. Being a software-based solution, it improves upon traditional application upgrade solution by eliminating the need of hardware load-balancers and duplicate cluster/domain configurations and their associated resource requirements and by providing sophisticated management capabilities.
