    Object store is quickly becoming the new core data substrate. Lets build kafka, but on s3. Lets build github, but on s3. It feels like we going to see more and more "object-store first" systems in the next few years.

    I am excited about this future. Give me stateless servers and a storage bucket over having to manage systems with disks any day.

    I do wonder if we will see an expansion of the s3 api to support more of these use cases. S3 added a janky file append operation to their new express-one-zone bucket type, and limited to 10k total file append operations. I wonder what else we will get in the next few years.

      doesn't that make egress fees egregious? or still cheaper than disks?

        This all depends on the cloud you are building on and if the data ever leaves the datacenter.

        You can download objects from S3 from EC2 without traversing the public internet using things like gateway endpoints [0] which avoids s3 egress fees. But doesn't avoid egress fees from EC2 to the end user.

        they are indeed egregious, like, downloading all your data one time costs about three times as much as buying disks to store it.
