The invention discloses a development, testing, operation and maintenance integration
system, deployment and a full-quantity and incremental updating method. The
system comprises an automatic deployment module and an automatic updating module, wherein the automatic deployment module configures corresponding
backup controller information and load balancer information according to mirror images in a
mirror image warehouse at a developer end, automatically generates an application deployment script, and automatically / manually spreads the application deployment script to a testing deployment end; the testing deployment end automatically deploys an application to the testing, operation and maintenance environment by executing an application deployment script file, the automatic updating module updates an application program according to the mirror images in the
mirror image warehouse at the developer end, generates an update pack file in a full-quantity or incremental updating mode and automatically / manually spreads the update pack file to the testing deployment end; the testing deployment end automatically deploys the updated application to the testing, operation and maintenance environment by executing the update pack file. Cooperation obstacles among development, testing, operation and maintenance are reduced, the cooperation efficiency is improved, application deployment processes are simplified, a developer pays close attention to business flows, and the requirement for technological levels of operation and maintenance staffs is lowered.
