To ensure the resilience and efficient operation of the cluster in senhasegura, especially in an environment with two nodes and one arbitrator, it is crucial to distribute these instances across different locations. This practice ensures that in the event of a failure in a data center or cloud instance, the other nodes continue to operate.
- Distribution in Different Data Centers (On-Premises):
- Strategy: Each environment (node) should be located in a different data center.
- Reason: If a problem occurs in a specific data center, the other nodes will still be operational, ensuring service continuity.
- Distribution in Different Networks or Instances (Cloud):
- Strategy: Each node and the arbitrator should be in distinct networks or instances within the cloud environment.
- Reason: In the event of a failure in a specific instance or network in the cloud, the other nodes and the arbitrator will remain operational, maintaining the integrity of the cluster.
For an optimized configuration of senhasegura in a cluster environment with two nodes and one arbitrator, it is essential to distribute each instance across different locations. Whether in an on-premises environment or in the cloud, this practice ensures that in the event of localized failures, the system maintains functionality and integrity, providing high availability and resilience.
