2 projects came out that implement scalable git hosting just by using an s3 bucket as the data plane thanks to the somewhat new conditional PUT primitive supported by S3: gitwal.io by Scott Chacon and github.com/tobi/walgit by Tobi Lutke. Implementations of cursor.com/blog/git-at-any-scale. Makes for a nice reading and I'm sure we'll see many new projects around that.
