Use the simple deployment mode in the following cases:
- For product evaluation and proof of concept. This mode allows you to get aware of the basic VAO functionality.
- If you need to delegate permissions on failover plan creation and maintenance to other users, and/or if you do not need to provide multisite enterprise delegation of permissions on failover procedures.
This mode will suit a situation when there are no security concerns regarding users who will perform failover plan management. This mode will also suit an administrator who is responsible for all disaster recovery operations in the company.
- As soon as you install a DR VAO server and connect standalone Veeam Backup & Replication servers to it, VAO will push its agents to all the servers.
VAO uses the agents to collect data about vCenter Servers managed by the standalone Veeam Backup & Replication servers, and to pass management command from the DR VAO server. That is why this mode applies only if there is no traffic limitation on data transfered between the DR site and remote Production sites.
The diagram below illustrates the simple deployment mode.
