Implementing High Availability (HA) across multiple data centers

[powersupport]

Hi,

We have multiple server DCs, located in the same location, and the latency is good, is it possible to set up HA across these DCs?

Thank you.

the latency is good

What does that mean?

Running a cluster is primarily dependend on the latency. If it is good as you claim, it'll work. If it's not, it will not ... very simple.

Hi,

Anyone can tell if it is possible to setup HA across multiple clusters?

Not yet. I'd go with service resilience, so run your services in a Paas fashion and do not rely on IaaS HA.

Hi,

Has anyone here had experience setting up high availability with multiple clusters? Could you please share any advice or insights on the possibilities?

There is no HA, ie transparent live failover, between clusters in PVE. You can get service recovery via replication, however that is only within a cluster natively at this time. There may be some improvements in this area coming down the pipe shortly.

The only option that is available today between two isolated clusters (or solo nodes) is migration. Obviously, for that to work both sites have to be up. So this does not qualify for HA.

Trying to find out if any progress has been made in multi-cluster HA. Like the previous poster, I have multiple DCs. I have 10G at each side and <15ms latency between BUT I don't really love the idea of trying to cluster across that.
