The list of what Kubernetes does is long and rapidly increasing. Together with Docker, it is becoming a platform that envelops the whole software development and deployment lifecycle.

The Kubernetes project has just started. It is in its infancy, and we can expect vast improvements and new features coming soon. Still, do not be fooled with “infancy”. Even though the project is young, it has one of the biggest communities behind it and is used in some of the biggest clusters in the world.

Do not wait. Adopt it now!

The result we accomplished through different Namespaces is very similar to what we’d expect by using separate clusters. The main difference is that we did not need to complicate things by creating a new cluster. We saved time and resources by using a new Namespace instead.

If this would be a “real world” situation, we’d run functional and other types of tests using the newly deployed release. Hopefully, those tests would be automated, and they would last for only a few minutes. We’ll skip the testing part since it’s not within the scope of this chapter. Instead, we’ll imagine that the tests were executed and that they were successful.

Communication is an important subject when working with Namespaces, so in the next lesson, we’ll spend a few moments exploring it.
