Ask HN: What are the gaps in current infrastructure software?

There's a lot of open infrastructure software out there, but it wasn't until recently that some problems got decent solutions (like prometheus for monitoring, kubernetes for orchestration, minio for object storage). What problems could do with fresh implementations? What's some internal software you wish had an open implementation?

If you had three months to work solidly on a new piece of open source infrastructure level software, where would you place your effort?

Use this thread to generally complain about infrastructure.
