Windows Containers are a lightweight form of virtualization that allow developers to package applications and their dependencies into a single unit. This makes it easier to deploy and run applications consistently across different environments, such as development, testing, and production. Unlike traditional virtual machines, containers share the host operating system's kernel, which makes them more efficient in terms of resource usage. These containers can run on any system that supports the Windows operating system, providing flexibility for developers. They are particularly useful for microservices architecture, where applications are broken down into smaller, manageable components. This approach enhances scalability and simplifies application management.
