Is loadbalancing over 2 or multiple HA-groups possible ?

Hi,

It are actually 2 datacenters (sites). The applications are cassandra database based. So as soon as 2 cassandra nodes drop, I lose consistency and the last surviving node in that site cannot handle any writes.

However, the 2 sites are in terms of speed equal with high bandwidth in between, hence the balancing over all nodes with 1 entry point, as if both sites were just 1 big application.

i was told that was not possible in active/active. So wanted to double check.

Not sure why you redirect to a sorry page. I actually want to continue processing in the other site.

So :

• 1 dns name, 6 nodes
• 2 sites, each 3 nodes
• service should ALWAYS be running
• if 1 node fails, it gets excluded from the pool, both sites continue to process
• if 2 nodes fail within the same site, that entire site is excluded from the pool, leaving the other site to continue handling the requests

Unless the 2 sites fail with 2 nodes each, I should never get a 500 error.
