Deployment Environments
Because of the availability and failover advantages of using a cluster, we recommend that Active Cluster be used in your QA/staging and production environments. Follow these guidelines:
• Deploy at least two clusters – one for QA/staging and one for production.
Note: Modifying the same/dependent artifacts on different servers in a single cluster may cause conflicts. So it is recommended to deploy separate clusters for development and production.
• Enterprise deployments should consider deploying multiple clusters.
• For production nodes, use 4+ CPU cores. These are minimum requirements. The actual configurations depend on such factors as the number of expected requests, number of clients, level of availability required, and so on.
• Since Version Control for TDV does not support clusters, it is recommended to use a single DEV instance.
