Docker For Mac/Windows
- In the past: Had to have VirtualBox installed on your machine
- Now: you can now run containers on OSX/Windows w/out VirtualBox
- How: Uses a technology called xhyve, which is a lighweight VM for OSX, to run Alpine Linux, which hosts the containers
- https://docs.docker.com/docker-for-mac/
Docker Swarm
- Problem: How do you manage many containers spread across many nodes? Orchestration
- In the past: Had to use a 3rd party tool like Kubernetes
- Now: Latest Docker beta (1.1.2) comes with Swarm Mode
- Provides very simple command-line API for complex orchestration
Talk: Docker For New Dev Setup
- Problem: New developer on job and need to get started working easily
- Solution: Docker for Mac + docker-compose
- Can live debug code within a container and push change to staging server via Docker Cloud

Micro-service Best Practices
- Consistent error messaging
- Use one base URL for everything
- consumers should not know they are hitting a micro service
- Micro-services are an implementation detail, so need to expose this to a consumer
