  3. Introduction • @spedge • Engineering Manager • Development Mechanics (DMX) • Deployment & Orchestration (DO)

  4. Once upon a time… I want you to create a platform that will deploy 10,000 changes a day to our website. Uhm. I think you mean 10? Nope, I mean 10,000. Ok, err. I think you mean a year? Nope, I mean 10,000 per day. Every day. Oooookay. Right. So…uh….any idea how? Nope, that’s what we pay for you for. But if you need anything, any support or any messaging – let me know. ….Gin?

  5. “The Jenkins Paradox” • Q: How did we find out that we were a strategic enabler? • A: When it became apparent we were a strategic roadblock…

  6. Schedulers

  7. The BIG PLAN

  9. High-Level Architecture Build Publish Package API SWF Gitlab Your Service ECS Lambda Continuous Integration Continuous Deployment “From source to service in zero clicks…”

  10. Registry • Your image registry is one of the most important parts of your infrastructure... • It will lull you into a false sense of security when things are going well... • But when you need it… • When you really, really need it.. • Unless you are prepared… • It WILL fail you.

  11. Does it scale?

  12. What’s Next? • Re-evaluating any tooling that isn’t cloud native. • Getting the hang of multi-tenancy hosting • Working harder at reducing technical obsolescence

  13. Deep Thought • Enablement isn’t doing something for a team, enablement is helping them do it themselves. • If you are experimenting with a new tool or process – find the quickest and easiest one to use. From that, learn about what you actually need. • The tools and systems that you’ve invested so much time in today will be considered obsolete tomorrow. Accept that as part of what you do as professional engineers – it’s part of the joy of software. • A journey of a thousand miles starts with a single step.
