Why Are Containers Isolated If They Share The Host OS Kernel? - Cloud Stack Studio

Why Are Containers Isolated If They Share The Host OS Kernel? Have you ever wondered how containers operate on a computer and what makes them both efficient and secure? In this video, we’ll explain the core concepts behind container isolation and sharing the host operating system kernel. We’ll cover how containers use features like namespaces and control groups to create separate environments for processes, filesystems, network interfaces, and resource limits. You’ll learn why containers are lightweight and quick to start, making them popular choices for deploying applications in cloud environments.

We’ll also discuss the security considerations involved with sharing a single kernel among multiple containers. You’ll understand the potential risks if a vulnerability is exploited and how cloud providers implement additional layers of security, such as sandboxing tools like Google’s gVisor or running containers inside microVMs for enhanced protection.

By the end of this video, you’ll gain a clearer picture of the balance between efficiency and security in container technology. We’ll share best practices for keeping your container environment safe, including kernel updates and security tools. Whether you're a developer, system administrator, or cloud enthusiast, this overview will help you grasp how containers operate and how to manage their security effectively.
