What do you dislike?

This technology is, as for today, still pretty new and amount of experienced specialists on the market is limited - but growing. If you switch from server- or VM-based approach, you might need to re-think infrastructure lifecycle management approach - it's pretty different with Kubernetes and might seem problematic in the beginning, but in end effect it forces you to architect your infrastructure in resilient way.

What do you like best?

Kubernetes does a really good job when it comes to container orchestration. It offers vast amount of feature sets, which allow applying modern container-based management techniques also for older applications. Being able to write custom operators allows to deploy very sophisticated infrastructure lifecycle scenarios. It has reduced time-to-live for our services by the order of magnitude. It also helps to avoid vendor lock-in and allows easy portability of your tech stack between various infrastructure providers, both in cloud and on premise.

Recommendations to others considering the product

If you want to start using Kubernetes, you might need to re-think infrastructure administration. It might seem to be irrational in the beginning, but you might want stop using older configuration management systems like puppet/ansible/chef/saltstack and re-think your application and service delivery towards containers and CI/CD pipelines.

What do you dislike?

It gets slower when there are many pods (over 100) and kubectl operations take too long to finish and would benefit from optimizing the speed of kubectl ops

What do you like best?

Extremely balanced and reliable and can fit into any big organization that seeks multiple environments and good CD, I like its ability to recover itself and keep all pods in sync

Recommendations to others considering the product

Use Kubernetes if you're going to create multiple environments and need scalability

What do you dislike?

The documentation isn't good. It's hard to find good information online. Since the product is changing a lot, we almost always get outdated information.

What do you like best?

The way that we can describe the entire deployment of the application is very good. It is easy to write and easy to understand.

Another good point is how easy to replicate the environment in another cluster.

What do you dislike?

Forced upgrades are sometimes a problem. Google will by default upgrade a k8s setup to the newest version, even if you're not fully ready for the change. It's frustrating, but can be worked around.

What do you like best?

K8s is very well documented and any issues that arise are typically solved by reviewing the documentation. It's well supported by Google.

Recommendations to others considering the product

It's google - so you know it's done right. They manage a huge infrastructure with this software, so it will likely handle your containerized platform requirements.
