Hi,
Thanks so much for coming to answer our questions.

For anyone working in large enterprise, especially something like FinTech, things tend to grow into huge scales. Are there easy ways to organize and group containers when they hit milestones of 10k, 20k,30k containers? In your experience do containers promote the building of less infrastructure or expand more when compared to VM's? I imagine people would want to build out more containers as microservices.

From the little I understand when coupled with pipelines docker can be extremely flexible and easy to update/deploy and roll back, (CI/CD). Is it easy to keep applications organized, and debug issues? Again especially as things scale across hundreds of applications?

Thanks!,
Peter

That's what products like Kubernetes are for. Once you start getting elastic, having a master console that can track all the instances of a container and parcel them out to servers in a balanced way is critical. I've currently got abput 4 Docker hosts running in production and probably not more than a dozen containers and while configuring and deploying them is easy, remembering which container is on which host is an annoyance. If I was to mega-scale it, doing it manually would be prohibitive.

Thanks Tim, thank makes sense. It makes sense where kubernetes fits into the picture. Thanks!

Best of luck on your book, I will try to check it out.
