Who really uses it?

Why Go?• Simple Compiled Language

• Good Standard Library

• Concurrency

• Synchronous Programming Model

• Garbage Collection

• STACKS!

Why Go?

• Not C/C++

• Not Java (or any JVM based language)

• Not Ruby/Python/Node.js

Why Go at Apcera?

Why Go at Apcera?• Best choice for distributed systems IMO

• Can test majority of system via Go routines

• Good core language, great(ish) performance

• easy to hire talent, because..

• easy to understand and grok in short period of time (its not erlang)

• Good standard library support - Get better faster!

• Great tooling that is built-in - a critical part of our CI

• go vet, go fmt, go test -race, etc

How do you build a Cloud OS?

Building a Cloud OS• Messaging System

• Distributed Scheduling System

• Orchestrator

• Policy Engine

• Isolation - Secure Perimeter Networking

• Semantically Aware Communications (for us)

Building a Cloud OS• Messaging System!

• NATS - High Performance (> 5M msgs/sec) and Secure

• Distributed Scheduling System!

• DDSS - Drop Dead Simple Scheduler (Mesos, Omega, Kubernates, Diego)

• Orchestrator!

• Own chef server, own Golang vSphere and OpenStack APIs.

• Policy Engine!

• pEngine: new policy language (dconf), secure distribution, pluggable enforcement

• Isolation - Secure Perimeter Networking!

• cgroupContainer (w/ user namespaces, networking) -> libContainer

• Semantically aware communications!!

• Transparent Semantic Pipelines and extensible frameworks

Where are we headed?

Go 1.3• Better GC

• Stacks now contiguous

• Defer is more performant

• Faster race detector - Please USE THIS!

• Go on Android and ChromeOS via NaCL

• My favorite: []byte -> string and vice versa is free

Why Go?

Its Simple! Its Getting Better Faster!

Its time for us to give back! !

Stay Tuned!
