Synchronize Plesk Servers (Failover)
Keep two (or more) Plesk servers in sync for a failover scenario.
Migration Manager only allows manual "sync"
it would be fine!
2013 ... gosch. It would also be good to have sync between subscriptions on different Plesk Servers.
As then Cloudflares IP based Loadbalancing would be awesome!!
please make a fail-over that can be used with two IPs and one server... that would be incrediably usefull.

All needed system tools are already available, you just need to write a GUI to set them up:
- MySQL supports replication; actually it can be set up via Tools & Settings > Database Servers > phpMyAdmin > Replication;
- Dovecot supports master/master replication using dsync: https://wiki.dovecot.org/Replication
- File replication: mmmmhh

Please add this plesk :D
I would love to have this, or on site level. lets say you build a site and active sync this to another server.

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.
Jan Bludau commented
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 ...

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.
