Containers have become a cornerstone of modern IT infrastructure, yet, despite their widespread adoption, many technical fundamentals behind the container ecosystem are not widely known and lead to confusion and open questions like:

- Are containers just lightweight virtual machines?

- What are the layers of a container image?

- Are containers inherently more secure than workloads running on bare metal?

This session aims to demystify the underlying concepts behind containers and container images. We will trace the historical and technical evolution, beginning with foundational features like namespaces and cgroups, and how they are employed by container engines like Docker and Podman. Then we will provide an overview of how container images are constructed and how containers are launched from container images by Docker and Podman.

Whether you are new to containerization or looking to solidify your foundational knowledge, this talk will provide you with the necessary groundwork to successfully navigate the containerization landscape.
