We orchestrate our IT landscape

Docker Build • Images with your application & entire env/system Ship • Share images (dockerhub.com, private registry) Run • Docker Client, Daemon, Registry

Conclusion Docker For Developers •

Isolated, repeatable and relocatable runtime environment setup

•

Isolation between containers and against the host

•

Fast and Simple in Use

For Operators

12

30.04.2018

•

A standard format for an „executable“

•

A unified API for operating these executables

Optimized for Kubernetes Any OCI-compliant registry Improved security Performance at scale

We orchestrate our IT landscape

We need more than containers

Scheduling

Security

Decide where to deploy containers

Control who can do what

Lifecycle and health

Scaling

Keep containers running despite failures

Scale containers up and down

Discovery

Persistence

Find other containers on the network

Survive data beyond container lifecycle

Summary & Conclusion

38

30.04.2018

We orchestrate our IT landscape

Summary ▪ Containerize you IT landscape is “No free lunch” ▪ Decide wisely between CaaS & PaaS

▪ If the your IT remains the same (ops, build, …) and Container is only a runtime to you, go with CaaS

▪ If DevOps is an option/goal, choose PaaS

39

30.04.2018

We orchestrate our IT landscape

Conclusion ▪ With PaaS you have more “vendor lock-in”, (even when building on standards)

▪ Think of support vs. diy ▪ Update & security

▪ Knowhow

40

30.04.2018

We orchestrate our IT landscape

Conclusion ▪ CaaS & PaaS usage is constantly growing ▪ Increases development velocity & robustness ▪ Operational efficiancy ▪ Basis for concepts like FaaS & “modern” architectures
