Application maintenance
Once infrastructure is deployed, updating it in a consistent way across all your AMS environments, from QA to staging to production, is the challenge.
This section provides an overview of the AMS workload ingestion process and some examples of different methods you can use to keep your cloud infrastructure layer up to date.
Application maintenance strategies
How you deploy your applications impacts how you maintain them. This section provides some strategies for application maintenance.
Environment updates can involve any of these changes:
Security updates
New versions of your applications
Application configuration changes
Updates to dependencies
Note
For any application deployment, no matter the method, always file a service request beforehand to let AMS know that you are going to deploy an application.
