Is realtime mirroring of virtual machines possible? If yes, how to mirror?

Answer 1

VM mirroring is synchronous replication with RPO 0. There are options depending on the goal:
1. VMware Fault Tolerance - a shadow copy of the VM, activated when the main VM fails
2. array-based replication - ala HPE 3PAR Peer persistence, etc. with a stretched vSphere cluster (on the second site there is also a read-only shadow copy)
3. if I’m not lying, the storage system has Split-mirror technology,
you need to understand whether to mirror virtual machine data on disk or the calculations themselves (CPU calculations, data in RAM) or all together.

Answer 2

How do you like this decision?
I haven’t personally tried it, my hands haven’t reached it yet, but I feel that it’s impossible to delay with this ...

Answer 3

such a thing

such a thing is called tabs. You should go to the codepen and look at the examples , there people are as soon as they are not burned out: both on pure CSS, and on scripts, and with wai-aria support, and without. In your case, this element is turned on its side instead of its traditional horizontal position.
