2. sendachi.com Enterprise DevOps in 2016 • Matt Saunders • Principal Consultant • Sendachi
3. sendachi.com Sendachi • Formed in 2016 • Merging Clutch (US) and Contino (UK) • VC Funded Services Company • Docker Premier Partner
4. sendachi.com Sendachi • Enterprise Focus • DevOps & Continuous Delivery • Containerisation & Virtualisation • Microservices • Security, Reliability & Resilience • Cloud Architecture
5. sendachi.com Matt Saunders • Old-school Sysadmin • DevOps since before it was cool • Twitter @cm6051 • matt.saunders@sendachi.com
6. sendachi.com London DevOps Meetup
7. sendachi.com Docker London Meetup
8. sendachi.com Cloud
9. sendachi.com Cloud
10. sendachi.com Private Cloud Adoption • The bad – Some failed projects – PaaS ideal is hard to realise – Private clouds encumbered by process – Agility hard to deliver
11. sendachi.com Private Cloud Adoption • The good – Accelerated by simpler requirements of Docker – Fewer dependencies – Shorter provisioning lead times
12. sendachi.com Public Cloud Adoption • The bad – Cost models still less understood – Replatforming for cloud-native is still rare – Enterprises with data-centre sunk costs
13. sendachi.com Public Cloud Adoption • The good – Enterprises keen to pilot public cloud – Enterprises understand public cloud is years ahead – Regulatory requirements often met
14. sendachi.com Public Cloud Adoption
15. sendachi.com Public Cloud Adoption
16. sendachi.com Containers
17. sendachi.com Containers
18. sendachi.com Docker • Enterprise adoption of Docker – 2015: 13% – 2016: 29% • Source: Rightscale
19. sendachi.com Docker • Larger Companies are the Early Adopters
20. sendachi.com Docker
21. sendachi.com Docker • Big money investors • $1 billion market cap
22. sendachi.com Container Benefits • Container Abstraction Layer – Common point of entry for containers – Run diverse technology stacks – HTTP with RESTful interfaces work well
23. sendachi.com Container Benefits • Platform Portability – Move applications easily between servers – Private and public cloud – Everything is contained
24. sendachi.com Container Benefits • Resilience with Clustering – Multiple clustering options – Built specifically for Docker – Docker Swarm gaining traction
25. sendachi.com Container Benefits • Provenance and Traceability – Container builds can be automated – Cryptographic signing of images – Docker registry communication is encrypted – Proof that an image is as-built
26. sendachi.com Container Benefits • Environment Consistency – Applications run entirely in containers – Environment info stored outside containers – The same container runs everywhere – Environmental drift is minimised
27. sendachi.com Container Benefits • Improved Resource Utilisation – Applications can be limited by memory or CPU – Pre-allocation of resource isn’t required – Docker containers can be multi-tenanted – Remove the virtualisation tax
28. sendachi.com Regulation
29. sendachi.com Regulatory Changes • Regulation becoming harder • But Enterprises being more prepared to deal with it • Leveraging Cloud, Containers and Regulation gains competitive advantage
30. sendachi.com Microservices
31. sendachi.com Microservices
32. sendachi.com Microservices
33. sendachi.com Microservices • Small replaceable services • Loosely coupled together • Deploy seperately • REST APIs • Independent backends
34. sendachi.com Microservices • Release at Independent speed • Continuous Integration • Continuous Delivery • Social Contracts
35. sendachi.com Microservices • Breaking up monoliths • Unsupportably large • Different release cadences needed • Carve bits off the edge
36. sendachi.com Microservices • Breaking up monoliths • Unsupportably large • Different release cadences needed • Carve bits off the edge
37. sendachi.com Microservices • Breaking up monoliths • Unsupportably large • Different release cadences needed • Carve bits off the edge
38. sendachi.com Microservices
39. sendachi.com Microservices: Not a Free Lunch • Significant DevOps skills needed • Significant Operations overhead • Distributed Systems complexity • Testability challenges
40. sendachi.com Microservices: Not a Free Lunch
41. sendachi.com Microservices: Continuous Integration
42. sendachi.com Microservices: Deployment
43. sendachi.com Organisation
44. sendachi.com Organisational Design • The bad – Silos can be rigid in Enterprises – Hearts and Minds hard to influence – Cross-functional teams hard to form – Limited scope of DevOps projects
45. sendachi.com Organisational Design • The good – DevOps pilot projects having some success – Not so many “DevOps teams” – Projects in large enterprises have a chance to flourish – Upskilling always welcome
