Containers and virtualization have changed the way we think about running applications. They’ve made things faster, more efficient, and much easier to manage – especially as environments grow more complex. In this chapter, we’ll take a closer look at what containerization is, how it compares to virtualization, and why it’s become such a big deal in the world of modern infrastructure.
Containerization is a lightweight way to package and run software consistently across environments – from a laptop to production. Unlike virtual machines (VMs), which each run a full operating system, containers share the host’s kernel, making them faster and more efficient.
While both containers and VMs allow multiple apps on one machine, they use different approaches. That distinction affects performance, resource use, and deployment speed – topics we’ll break down with clear examples. It’s also worth noting...
