Kubernetes – the solution to all of our problems?

Viktor Farcic: My understanding is that you mostly work with Kubernetes, which means you're into the latest and greatest. Is that a concern for you?

Ádám Sándor: We've never had experience with this technology failing, so in that sense, it's not an issue in that it's the latest and greatest. We never advise customers to jump into something, even though we are surfing on the edge of new technology and watching out for everything that's coming our way. Usually, we recommend technologies that have already proven themselves for at least a year and that we know will work for the customer.

Viktor Farcic: Does that mean everybody should move to Kubernetes? What does it involve? I imagine it's not only creating new Docker images and YAML files. Let's say that I'm a company that has existed for a long time and I have everything, how does it look for me?

Ádám Sándor: For such a company it will start with a proof of concept to prove internally whether Kubernetes works for you. Depending on your short term plans this will either focus on moving a legacy application to Kubernetes or creating something new using technologies the company plans to move towards. Whether a company wants to move some or all of it's legacy applications to Kubernetes can depend on many factors. What I would point out is that it's not impossible or even undesirable to do so.

Kubernetes is actually a surprisingly good system for supporting legacy applications, for example, with simple things like being able to inject configuration into a pod using files. You can very easily simulate a configuration files-based environment to old-school services that require huge config files, and so containers are a pretty backward-compatible technology.
