As organizations continue to pursue their digital transformations, their IT infrastructures are expanding in both size and diversity. Many are seeing the addition of two new technologies in particular: containers and Kubernetes.
Containerization has replaced virtual machines to a great extent because containers are lightweight and make efficient use of the OS kernel. Docker’s efficient nature helps with software development, testing, delivery, and deployment in a DevOps environment, and all the benefits of Docker also apply to Kubernetes. Let’s explore some of the additional agile and DevOps benefits you can gain by using Kubernetes.
Ryan Kenney, senior consultant at Coveros, chats with TechWell community manager Owen Gotimer about the difference between containers, container engines, and container orchestration; using containers in your CI/CD pipelines; and the cost of security.
Containerizing applications introduces major changes to the way we run those applications. We can now share infrastructure and resources, but this introduces the need to control the way resources are used—from a sanity perspective first and a financial objective second.
Docker is the most popular containerized solution being used in the software industry for development. However, implementation can get complicated, tricky, and unmaintainable if all you understand is the record-and-playback features or think it is the same as using a virtual machine.
