In one recent article, we covered Virtualization vs. Containerization. In this article, we would like to take you through Kubernetes, which has been used by many companies for containerization.
Earlier enterprises used to have physical servers with basic services, such as Apache, Bind, MySQL, and PHP. Then, there came the need for migrating those servers because another service provider offered a better price. Updating was hard when there were multiple websites hosted on the server because some of them relied on specific versions. Because of these issues, enterprises often ended up keeping some servers and avoid the pain of migration. This is probably a familiar scenario to most of you!
- Run a cluster of containers.
- Manage deployments of applications across those containers.
- Monitor these containers.
- Deploy applications quickly and predictably.
- Scale applications on the fly.
- Seamlessly roll out new features.
- Optimize use of hardware by using only the resources that are needed.
Kubernetes has been built on software that has been developed at Google. It has been running their workloads for more than a decade. Since its announcement, Kubernetes has been one of the most popular repositories on GitHub.
The project has seen significant backing from multiple vendors, and one of its most notable features is that it is able to run across multiple cloud providers and even on-premise infrastructure. It is not currently tied to any particular vendor.
