Active/active clustering

[Steve92]

Hi!

Today, only active/passive clustering can be used with ECS V8.

Will active/active clustering be available with V9 ?

Regards,

Steve.

Hi, in version 9 an Enterprise Cloud Server Cluster (ECSC) is a pair of Cloud Servers that work together to maintain high available access to the centralized infrastructure. Let me sum up how it will work. This is an active-active cluster where the cluster master and slave roles can be switched between the primary and secondary servers. The master is in charge of distributing client connections and the load of session negotiation and management between itself and the slave. The primary and secondary server constantly monitor each other, hence active/active. When one of the servers loses contact with the other one, it replaces the failed server. Sessions already managed by this working server remain connected and the failover is transparent for them. The management of sessions handled by the failed server is passed from the failed server to the working server. The sessions running on the remote nodes continue to be running (they are not lost during the failover), but clients will have to reconnect to them.

Hi,

When, very approximatively, will V9 be released ?

We can’t wait for it and have to find a solution to get load balancing with v8.

Are ECS compatible with HAProxy solution in TCP (NX) mode ?

What third-party solution can handle load balancing between many ECS ?

Thanks,

Regards,

Steve.
