I'm sure you've heard of containers, but have you heard of images? In this course, Containers and Images: The Big Picture, you'll learn about the big picture of both. This course will help you understand why containers exist and what exactly a container is, down to the level of understanding what changes in the Operating System to support these. You'll learn a bit of history and begin to understand the significance of images because without a means of distributing images for containers, containers wouldn't be a big deal. You'll learn how image technology can be brought to highly optimized VMs and other execution environments. In doing this, you'll start to see where the future of app packaging and distribution is heading. After this, you'll learn about some ways you can get started with the benefits of containers and images outside of production environments, and finally, you'll explore what your infrastructure might look like when you need to scale to large capacity with hundreds or thousands of containers. By the time you're done with this course, you'll have a good understanding of the what and why of containers, images, and clusters.
