More detail below, but the the crux of my question is: What's the best way
to spin up/down "on demand" an ES cluster on EC2 that uses ephermal local
storage? Essentially, I want to run the cluster during the week and spin
down over the weekend. Other than brute force snapshot/restore, is there
any more creative way to do this, like mirroring local storage to EBS or
Some more background:
We run multiple ES clusters on ec2 (we use opsworks for deployment
automation). We started out several years back using EBS because we didn't
know any better, and have switched over to using SSD based local storage.
The performance improvements have been unbelievable.
Obviously, using ephermal local storage comes at a cost: we use
replication, take frequent snapshots, and store all source data to mitigate
the risk of data loss. the other thing that local storage means is that our
cluster essentially needs to be up and running 24/7, which I think is a
I'm investigating some ways to save on cost for a large-ish cluster, and
one of the things is that we don't need it to necessarily run 24/7;
specifically, we want to turn the cluster off over the weekend. That said,
restoring terabytes from snapshot doesn't seem like a very efficient way to
do this, so I want to consider options, and was hoping the community could
help me in identifying options that I am missing.
thanks in advance for any thoughts you may have.
