10. Hit me up on Twitter: @mhausenblas 10 • Manual == brittle & error-prone • Playbooks? • Agility? • Bus factor? Automation
11. Hit me up on Twitter: @mhausenblas 11 Immutable infrastructure
12. Hit me up on Twitter: @mhausenblas 12 Immutable infrastructure • Good old pets vs cattle • Idempotence?! • Increased reproducibility
13. Hit me up on Twitter: @mhausenblas 13 APIs The API (not the implementation) is important! Examples: • HDFS • GraphQL • Kubernetes API
14. Hit me up on Twitter: @mhausenblas 14 APIs • Decoupling • Open, standardized?! • Declarative?

23. Hit me up on Twitter: @mhausenblas 23 … and beyond • portability between environments • appropriate unit of deployment such as a container or a function • typically dealing with distributed systems • elasticity—workload-dependent auto-scaling 301.sh/cloud-native-def-wip
24. Hit me up on Twitter: @mhausenblas 24 Portability • Avoid platform lock-in • Enable hybrid cloud deployments • multi-cloud • on-premises and cloud
25. Hit me up on Twitter: @mhausenblas 25 Unit of deployment • Physical servers • VMs • Containers • Functions
26. Hit me up on Twitter: @mhausenblas 26 Distributed systems • Scale out on commodity hardware • Fallacies of distributed computing

27. Containers & Container Orchestration
28. Hit me up on Twitter: @mhausenblas 28 Containers 101 containerz.info … a process group on steroids using namespaces, cgroups, and a copy-on-write filesystem
29. Hit me up on Twitter: @mhausenblas 29 Container orchestration
30. Hit me up on Twitter: @mhausenblas 30 Container orchestration kubernetes.io • Container lifecycle management • Declarative, state-driven • Extensible, modular API • Robust, flexible, scalable
31. Service Meshes
32. Hit me up on Twitter: @mhausenblas 32 Service meshes istio.io • Traffic management • Monitoring & tracing • Policy enforcement • Service identity and security • No app code changes
33. Data Meshes
