- 59. Google Cloud Platform 59 Thank you @craigbox
- 61. Google Cloud Platform 61 • Lightweight Linux environment • Hermetically sealed, deployable application • Introspectable, runnable artifact • Recently popularized by Docker Containers
- 62. Google Cloud Platform 62 Necessary, but not sufficient
- 63. Google Cloud Platform 63 Optimizing packing shared cell (original) shared cell (compacted) non-prod load (compacted) prod-only load (compacted) # machines 25% overhead
- 64. Google Cloud Platform 64 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?
