Recap
Matthias Haeussler / Novatec - @maeddes #CFMEETUP #CLOUDFOUNDRY
Kubernetes❏ “Live” editing of the running config❏ “built-in” Zero-Downtime deployment behaviour❏ Large functional scope❏ Very granular configuration possibilities
❏ Very granular configuration possibilities❏ Skill demand beyond app dev level (Docker & K8s)❏ Container handling❏ Aggregated Logging
Matthias Haeussler / Novatec - @maeddes #CFMEETUP #CLOUDFOUNDRY
Cloud Foundry❏ simplicity❏ “Containerless” - power of containers without interacting with them❏ Fast “app to platform” path❏ Buildpacks
❏ Buildpacks❏ Reduced configuration possibilities❏ “Manual” Blue/green deployment❏ Imperative commands
Matthias Haeussler / Novatec - @maeddes #CFMEETUP #CLOUDFOUNDRY
You can do more, But you need to know more
Matthias Haeussler / Novatec - @maeddes #CFMEETUP #CLOUDFOUNDRY
Much simpler, But does it give me all I need?
Matthias Haeussler / Novatec - @maeddes #CFMEETUP #CLOUDFOUNDRY
Future wish:Simplicity of cloud foundry with functional scope of kubernetes
