How to Scale PostgreSQL on AWS: Learnings from Citus Cloud
I saw the section on EBS, but it didn't offer much advice. Getting good performance on networked storage is the biggest challenge to me. The last time I asked about that here [1], I got this answer:    nasalgoat 161 days ago [-]

    The secret to EBS is to use General SSD,
    not Provisioned, but use a RAID stripe.

    The reason this works is because IOPS are provisioned
    per EBS drive and by the size of the drive. So a RAID0 
    stripe of, say, ten General SSD drives will outperform 
    the more expensive PIOPS single drive.

That sounds like a great approach, although I haven't had time to try it out yet. I'm curious if anyone else has done anything like that.[1] https://news.ycombinator.com/item?id=12609172
