technology to utilize automation and architectures to
manage complexity and unlock velocity

35. Google Cloud Platform 35
Containers have taken the
world by storm!
• 2013: LXC is a niche technology
• 2016: “Container” wins buzzword bingo
It’s a huge paradigm shift
• VMs are out, containers are in
It’s happening way faster than
anyone could have predicted
• Adoption is up 5x in 12 months
The right tech at the right time

36. Microservice oriented

37. Google Cloud Platform 37
Avoid tight coupling

38. Develop and deploy on different schedules

● Container orchestrator
● Builds on Docker containers
○ also supporting other container technologies
● Multiple cloud and bare-metal environments
● Supports existing OSS apps
○ cannot require apps becoming cloud-native
● Inspired and informed by Google’s
experiences and internal systems
● 100% Open source, written in Go
Let users manage applications, not machines

Kubernetes & Container Engine
Containers are powering a revolution
For Developers:
Easy dev-test environments
Easy to compose micro-services
Update your cluster with one command
For Ops/IT:
Kubernetes is managed for you
Deploying becomes file-copy
Highly portable

This might be a big change for you!
Move to using containers for packaging
Docker, rkt
Set up continuous integration & continuous delivery
Jenkins, Spinnaker
Would you rather do less work?
Use App Engine
Would you rather use the tooling you have in place today?
You can do that too
Walk, don't run

65. How do I get there?
