Docker©* containers play an important and increasing role in modern IT stacks. Making containers part of your architecture can make your applications flexible, resilient and platform independent.
A containerized application typically runs on one or more containers that are encapsulated with all the dependencies and configurations needed to run the application. The application is not only portable but also runs consistently across environments and operating systems. The application can also scale dynamically and almost instantly.
A more complex container environment requires an orchestration software. The best-known orchestration platform is Kubernetes©. Kubernetes is also offered as a tool by various software vendors (VMware-Tanzu, Redhat- Openshift, HPE-Ezmeral) or as “Platform-as-a-Service” (PaaS) by cloud providers (AWS-EKS, Azure AKS, Google GKE).
“Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications.
It groups containers that make up an application into logical units for easy management and discovery.”
Architecting, building and managing a Kubernetes cluster(s) can be a complex task. We have a lot of experience in this area. If you want to know more about how Containers and Kubernetes can be part of your environment, do not hesitate to contact us. One of our experienced CKA (Certified Kubernetes Administrator) consultants will be happy to help you!
“A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.”
*Next to “Docker” there are also other open source container initiatives like https://opencontainers.org/
