Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry What this talk is not about ❏ Everything below container level ❏ Platform infrastructure ❏ Vendor-specific implementations

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry What this talk is about app app deploy recovery (auto) scaling external configuration service bindings (aggregated) logging zero-downtime deployment

DEMO

RECAP

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry You can configure more, But you need to know more

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry Much simpler, But does it give me all I need?

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry ❏ “Live” editing of the running config with “built-in” Zero-Downtime deployment behaviour ❏ Large functional scope with Very granular configuration possibilities ❏ different levels of service exposure and easy service discovery ❏ very robust and resilient core ❏ popularity - exploding CNCF ecosystem, big oss community, everywhere available the advantages of Kubernetes

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry ❏ Very granular configuration possibilities ❏ Skill demand beyond app dev level (Docker & K8s) ❏ Container handling - build, maintain, registry ❏ Aggregated Logging ❏ requires more from ecosystem: helm, istio, prometheus, etc the problems with Kubernetes

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry ❏ simplicity ❏ “Containerless” - power of containers without interacting with them ❏ Fast “app to platform” path - developer productivity ❏ Buildpacks ❏ maturity level the advantages of Cloud Foundry

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry ❏ Buildpacks ❏ Reduced configuration possibilities ❏ “Manual” Blue/green deployment and staging ❏ Imperative commands ❏ “boring” the problems with cloud foundry

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry Future wish: Simplicity of cloud foundry with functional scope of kubernetes

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry options

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry eirini Pluggable container orchestration for Cloud Foundry, and a Kubernetes backend

Matthias Haeussler / Novatec - @maeddes #springio19 #cloudfoundry cloud foundry architecture
