Criticism and help on Vmware infrastructure?

Question

VMware

Actually, criticism and help in building such an infrastructure is required.
Live server replication and failover are required, while two identical infrastructures must lie on different subnets and be accessible via DNS round-robin. thanks for the help

Answer 1

From the picture it is not clear, I would like a more detailed description.
For the main site, you can use storage that supports volume synchronization / mirroring (for example, HP P4000) and organize one VMware vSphere cluster that includes two sites. As for DNS failover / Round Robin, it's not entirely clear, AD and Exchange have built-in failover mechanisms.
For a remote site, you can use VMware Site Recovery Manager, or a more budget-friendly option is to create VM replicas using Veeam Backup & Replication.

Answer 2

I also have a few questions - the distance between the infrastructures? what is the channel between them? what is meant by infrastructure identity? What is nat/pat for? what services need load balancing? What services require failover?
It seems to me that we need to approach from the other end - tell the introductory in more detail what you will have there, what budget, what is already made of iron, and so on.
A two-site HA cluster is sometimes not the most convenient solution due to the inconvenience of keeping track of HA primaries and constantly maintaining the correct balance.
