  • Message Queues
  • User Directories
  • Security Services
  • Machine Learning Services

Container Centric

Allows complete flexibility and control over the container

  • environment. It is a platform for building platforms.

Kubernetes

slide-31
SLIDE 31

Application Centric

Easier to learn, quicker to use but comes at the cost of flexibility. To be simple it needs to be opinionated.

Cloud Foundry

So who should care about containers?

slide-33
SLIDE 33

In depth container knowledge is perfect for:

  • DevOps engineers (at large companies)
  • Building a Cloud Platform
  • Running a highly available distributed service
  • Deploying highly customised workloads
  • Enthusiasts!

Where should I put my workload?

slide-35

Start building a new app...

Can it be built as decoupled functions? Can it be containerized? Serverless / FaaS PaaS Kubernetes Virtual Machine Is response time important? Is it stateless? Yes No Yes Yes No No Yes No

slide-36

Summary

  • Abstract as much as possible
  • Rent/buy as much as possible
  • Focus on software development
  • Learn containers only if it makes sense to do so
