Do you know more about Kubernetes than ChatGPT?

Sometimes it can be hard to get clear answers on the tricky topics in the world of cloud native. Which is the best service mesh? Is platform engineering just another label for devops? Is multicloud a risk?

If you can’t get a straight answer from a person — why not ask a machine?

So we spent a little time with ChatGPT and asked it some questions. GPT was coy about whether it runs on Kubernetes itself or not, but we think it’s kinda appropriate for an app to give its view on infrastructure, don’t you think?

(incidentally, the images in this blog were all generated by Dall-E)

Do you think the adoption of Kubernetes will continue to grow, or will some new alternative emerge to challenge its dominance?

Kubernetes has become the leading platform for managing and deploying containerized applications, and its popularity has continued to grow in recent years.
