The Evolution of Containers
Containers represent a significant shift in Software Development, providing a lightweight alternative to Virtual Machines. By utilizing Operating System-Level Virtualization, they allow multiple isolated applications to run on a single host by sharing the Kernel. This efficiency is powered by Linux features such as Cgroups and Namespaces.
The industry standard for creating containerized applications was established by Docker, which simplifies the process of packaging code and dependencies into Container Images. For managing these applications at scale, Kubernetes serves as the leading Container Orchestration engine. Detailed insights can be found at the Docker Information Center and the Kubernetes Documentation.
Containers are essential for Microservices architectures and are a key component of DevOps workflows, enabling Continuous Integration and Continuous Deployment.
