Synchronize Plesk Servers (Failover)
Keep two (or more) Plesk servers in sync for a failover scenario.
Migration Manager only allows manual "sync"
We hear you and see a clear demand for this feature.
I want to say that implementing these features requires a lot of investment, and in 2021 Plesk team keeps focusing on the delivery of other improvements (sad, but true).
We will back to the re-evaluation of these features at the beginning of the next year.
Please continue to share your use cases and requirements, and it would really helpful if you point to existing solutions that we can review and check before implementation.
Your feedback is important to us. Thank you, everyone.

Put this Option in your paid extension! is automatic also available ?
Automationsettings for DB replication between two Plesk servers to have a live backup or a second DB Server for Performance resons.
I could even imagine to use the upcoming Cloudflare loadbalancing function and two Pleskserver for higher performance or just high availability.

cluster is crucial, we need that option. also the ability to have more concurrent connections.

i agree this would be a very nice "why using plesk?" answer.
this sync would always be a nice functional backup.

If there would be a failover functionality in Plesk, we would most probably choose this solution for hosting 15 000 hosting accounts. But, it does not and failover/cluster is a must for us.
Let me know when you have the functionality in place ;-)
Anxious to see the new plesk multi-server roll out fully in 17, but this would dramatically improve our ability to host sites in a highly available manner, even when they are already hosted on Azure or AWS. I'd vote 5 times if I could.
would be great
not needed anymore - i have created my own Sync Solution with Failover
If you Need some Solutions for Failover, let me know via Email
i wish this Feature would be on top of your todo-list ...
Please can you tell me, are you resolved user data issues for plesk clustering. I want to also deploy cluster with plesk but issue is that how to mange users details after failover.

That would be brilliant !
I would love to see something like this. Maybe this could be accomplished by allowing at installation time the option to have the PSA and Website files/databases assigned to a separate location, possibly a Percona DB cluster and NFS file storage cluster. Then each subsequent plesk server could connect to the common storage cluster...
Obviously a lot of other details to figure out regarding pushing updates to all nodes without breaking the cluster, IP addressing issues, etc...
But this would be a great feature for ensuring that your services stay online, even if hardware fails...

It would be very nice, if it would be possible to use Plesk in a redundant environment, like a master / slave configuration. Where the slave can take over if the master isn't available anymore.
Or even better a load balanced environment, where all Plesk servers have the same functionality (like master - master replication in MySQL) and an outage of a single server does not interrupt any services at all.

Mirror two servers so that one can be used when primary server is down.

Well, if it's just email, just coded something for this in php ;)
The only thing you need to change is the source from where it should copy stuff.
Obviously only works on debian/ubuntu flavour servers and yes, it needs root (because of the file permissions for the files it needs to read to connect to the db/get the key)

just adding my 2 cents-
we've had to move away from plesk in some of our hosting efforts so we can have better HA.
we've had to build large clustered web systems, which is not ideal.
we lose the primary tools our customers have grown to love, and our staff understands: plesk.
we would love to see some solution around plesk being clustered.
if we had a this, it would allow us to shutdown a plesk node, and keep the services up- we would probably drop our complex beast in favor for it.
there are many options, and we've even done labs to see if we could trick plesk into being this way. We fault at IP failover, there's not an easy way to create a floating IP setup.
We have looked at software load balancer to address this- but to make the whole thing slick, and keep the plesk updates flowing we would need a vendor-supported solution- so we stopped in our efforts.
For future reference (if needed), we were looking at this: http://securityrouter.org/
the interface is easy enough for most plesk admins, or IT generalists to deploy and use.
Hopefully you guys will get this feature up and running one day!

@Odin: there are many people waiting for a feature like this. Can we expect it in a narrower future?
That would be a great feature ... for a better sleeping...
