This got me excited, then I checked the source and found out it's still in Scala. Which is... "not for everyone", right. At least the part where one needs a JVM to run it. I was really hoping for something lighter-weight.

If you can't justify spending a paltry few gigabytes of RAM to middle-manage your infrastructure, maybe you don't yet have the kind of colossal scaling problem that *needs* microservices?

To be fair, the less you have to scale vertically, the less your horizontal scaling will cost. Though I don't think a 100 MB RAM JVM is going to be a big problem unless you plan on something like Toasters as a Service. GCs usually get efficient if the heap is about 6 times as big as it needs to be, and at that point you're still only at 600 MB RAM. At any rate, I doubt the bottleneck will be in linkerd.

Well, linkerd-tcp is in Rust. Just recently got posted to /r/rust, in fact: https://www.reddit.com/r/rust/comments/62avcc/introducing...
