Network Structure Used in this Tutorial

In this tutorial three nodes will be created. Node-A and Node-B will be used as the Active node and Standby node, respectively. In addition to these two nodes, Node-C (the Quorum/Witness node), will also be created. (See What is for an explanation of the need for a Quorum/Witness Node).

As discussed in How Workloads Should be Distributed when Migrating to a Cloud Environment, SIOS strongly recommends the use of split workloads within different Availability Zones (‘datacenters’).

*Although this Evaluation Guide discusses the Quorum / Witness Node (node-c), this third node may be skipped to simplify the learning experience. However, for a production environment (or a formal PoC project), SIOS strongly recommends the use of the Quorum/Witness node.

In the following topics, nodes in different Availability Zones will be created.
