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. Containers are also an important part of IT security. By building security into the container pipeline and defending your infrastructure, you can make sure your containers are reliable, scalable, and trusted.
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.
Containers let developers focus on their apps while operations focus on the infrastructure—container orchestration is the way you manage these deployments across an enterprise.
Kubernetes is an open source platform that automates Linux container operations. It eliminates many of the manual processes involved in deploying and scaling containerized applications. Kubernetes gives you the platform to schedule and run containers on clusters of physical or virtual machines.
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 cloud-native development style, so you can get started with DevOps, CI/CD (continuous integration and continuous deployment), and even go serverless.
Container-based applications can work across highly-distributed cloud architectures. Application runtimes middleware provides tools to support a unified environment for development, delivery, integration, and automation.
You can also deploy integration technologies in containers, so you can easily scale how you connect apps and data, like real-time data streaming through Apache Kafka. If you’re building a microservices architecture, containers are the ideal deployment unit for each microservice and the service mesh network that connects them.
When your business needs the ultimate portability across multiple environments, using containers might be the easiest decision, ever.
