Pause = delete VM. Resume = remount volume and keep going. Built a self-hosted cloud coding agent on k3s + Kata VMs, but the key trick is storage: JuiceFS (Redis metadata + S3 data + cache) makes sessions truly persistent.

Some users use JuiceFS with CephFS RADOS, as alternative with Ceph MDS.

Agree, don't recommend POSIX proxy on S3 for complex workload, like S3FS. In the design of JuiceFS, S3 is like raw disk, JuiceFS metadata engine is like partition table, compare with local file system.

Can run MySQL and PG, but don't recommend, not good performance for production. but for temporary it's OK. Here's a case study -> https://juicefs.com/en/blog/user-stories/xiachufang-mysql-ba...

And here's a POSIX compatibility comparison with other cloud file system, like AWS EFS. https://juicefs.com/en/blog/engineering/posix-compatibility-...

metadata backup is very important. don't forget.

The MLPerf performance of JuiceFS last year, FUSE client, and TCP/IP network. There're some analysis about performance and bottleneck. -> https://juicefs.com/en/blog/engineering/mlperf-storage-v2-ai...

Truth. It supports very large volume, more than 100PiB and 10B files in a single volume.

Disclosure: I'm co-founder of JuiceFS

yes, support more 10 options, include redis, SQL-like DB, TiKV, FoundationDB, and more. see here -> https://juicefs.com/docs/community/databases_for_metadata

I'm from JuiceFS team. We run JuiceFS full managed service on every public cloud worldwide for 4 years. We decide open source it for more explore and usage.
