The application will be made up of the following components:

• A web server

-Steps to confirm the web server is operating correctly will take 15 minutes after the application server is online.

• An application server

-Steps to confirm application server integrity will take 15 minutes after the database is online.

• A database server

-The database server will be managed by a database administrator, with an agreed service-level agreement (SLA) to restore and validate database services within one hour.

The existing VMware infrastructure offers a recovery point objective (RPO) of 5 minutes and recovery time objective (RTO) of 15 minutes through a combination of backups and replication.
