WVD Session Host High Availability
zimmie Hopefully I can help with some items. With WVD you get some HA built in. The endpoint that users connect to is a Microsoft service, so that part is quite resilient. The Servers or Windows 10 Multi-Session when deployed automatically comes with a AV set that the system is put into. If you deploy with 10 VM's in the Host Pool, they will all be part of that single AV set, so that part is good. Then if you use FSLogix with Azure Files you will also receive a highly available profile for the users.
Let me know if you have more questions on this.
Jeremy Brewer thanks for the response. Just to make sure that i am clear: Session Hosts are automatically built in ScaleSets, so there is local redundancy already. What if there is a datacenter outage?
If we use Azure Files or NetApp Files for the FSLogix profile container, those services have built in resiliency as well.
If, for whatever reason, we go with a traditional file share on a VM and I want redundancy, I assume setting up a DFS share between 2+ servers would work.
Again, thank youzimmie I was reading through documentation the other day and I THINK that is all correct. The VM's are in AV Sets to start, but you are NOT getting zone redundancy with the VMs. If you need to protect the VM's like that you may be looking at doing something like Azure Site Recovery or Cross Regional Backups.
With Regards to the profile containers, I am not sure what NetApp files is doing for HA and regional recovery, I have not looked into it. The Azure files has some protections and if you have Geo-Redundant enabled then at least your data is made available in a MSFT declared disaster in the paired region. Lastly, if you go the route of a File Share server, I believe most people are going with 2 servers and using storage spaces direct. I know that shared disks in Azure was announced a little bit ago, so perhaps clustered storage is also usable? I am just not sure what limitations that introduces in Azure. I do believe some people were having success with DFS, I have not, so i just use name spaces but not syncing.
Happy to help 🙂
Still not getting whether Host Pool is multi-regional or not. Hosts may be located in different regions, that is clear but if the host region is down whether or not the host object will be alive itself? Will VMs be able to connect to the pool and be available to the client?
