WordPress cluster solutions? What are the best places to get them?

[MRIK]

Any good and reliable provider offering WordPress cluster automatic scaling?
Do you know anything about Jelastic and its auto-clustering solutions?
I've found them with Google search. Any reviews? What do you know about them?

Any alternatives for comparison?

They are great. I have several clients who have had a good run dealing and their auto-clustering solutions.
For example, one of the possible cluster topologies that their solution supports: 2 x Load Balancer + 2 x App Server + 3 x MariaDB Galera + 2 x Storage Container + 2 Redis (per request).
Just contact them directly for further details, OP
