Understanding Linux containers

Applications are getting more complex. Demand to develop faster is ever-increasing. This puts stress on your infrastructure, IT teams, and processes. Linux® containers help you alleviate issues and iterate faster—across multiple environments.

What are Linux containers?

Linux containers are technologies that allow you to package and isolate applications with their entire runtime environment—all of the files necessary to run. This makes it easy to move the contained application between environments (dev, test, production, etc.) while retaining full functionality.

Linux containers help reduce conflicts between your development and operations teams by separating areas of responsibility. Developers can focus on their apps and operations can focus on the infrastructure. And, because Linux containers are based on open source technology, you get the latest and greatest advancement as soon as they’re available. Container technologies—including CRI-O, Kubernetes, and Docker—help your team simplify, speed up, and orchestrate application development and deployment.

What can you do with containers?

You can deploy containers for a number of workloads and use cases–big to small. Containers give your team the underlying technology needed for a modern approach to software development, such as DevOps and CI/CD (continuous integration and continuous deployment). You can also deploy integration technologies in containers, so you can easily scale how you connect apps and data.

When your business needs the ultimate portability across multiple environments, using containers might be the easiest decision, ever.
