Elasticsearch Deployment architecture

Dinesh_Chandra · April 29, 2014, 10:40am

Hi,

I am very new to elasticsearch, I am trying to deploy elasticsearch in my
dev environment - While there are many ways in which Elasticsearch can be
deployed, I and my team have arrived at this architecture

4 Data Nodes
3 Master Nodes
2 Search Load Balancers (SLB)

Now my question is:

Does it make sense to have SLB at all?
Can I just have master nodes and have them perform the JOB of SLB too?

Please enlighten me on a sensible Elasticsearch Architecture!

1 - Yes if you do a lot of intense querying, eg facets.
2 - Yes that's perfectly fine.

We have a 20 node cluster, with 3 master only nodes that also act as our
search nodes, and the setup works great for us. We may need to revisit this
in the future though.

On a related note, if you have separate slb and master, your main LB (say,
haproxy) would be pointing to the slb , not the master , right?

For searches, yes. You'd want the indexing to go to the masters.

Sending indexing requests to SLB - is this less optimal, or would outright
fail?

It will work, but if you want to maintain HA then it'd make sense to keep
your inputs separate from your outputs. At least, that's my take
