Consul vs Pacemaker

[Chaman Bagga]

Hello,

Looking at consul documentation, there is comparison with etcd, zookeeper etc. However, its not clear how consul and pacemaker differ.

Can someone point out please?

Chaman,

The two differ in scope. Pacemaker is really only designed to do membership and failure detection

at small scale (< 50 nodes). Consul provides a much broader scope of features including

service discovery, key value, and coordination (including leader election and failure detection),

but is designed to operate at much larger scale. 

Hope that helps!

Best Regards,

Armon Dadgar

Thanks.

Does Consul also offer failover support like pacemaker does (e.g. using Virtual IP for failover)?

I have a few services that use VIP for failover today, and my clients use hardcoded IP, so VIP is a necessity.

Chaman,

Take a look at the “consul lock” command (https://www.consul.io/docs/commands/lock.html) for easily

doing fail over between services. That is based on the Consul implementation of leader election under

the hood (https://www.consul.io/docs/guides/leader-election.html).

Consul does not implement it at the VIP layer however, it is implemented much higher up the stack,

as it is designed to work in environments without VIP (e.g. public cloud environments).

Hope that helps!

Best Regards,
