About this course

Containers are units of software that package code and its dependencies to ensure applications run quickly and reliably across environments. In this course, you will explore the key differences between virtualization and containerization and the key benefits provided by both. Then you will differentiate between Kubernetes and Docker container solutions and find out why more teams are adopting containers. Next, you will examine how containers make DevSecOps. You will investigate common security challenges presented by containers, such as attack surface size, and you will learn how features such as application programming interface (API) microgateways can be used to complement programming language frameworks to help secure development practices. Then you will focus on how Cloud Native Buildpacks (CNB) and Paketo can be used to build modular container images that can help transform source code using modular, reusable build functions. Finally, you will learn how a strong culture can help provide top-tier container security.

Learning objectives

  • Discover the key concepts covered in this course
  • Differentiate between virtualization and containerization and outline key benefits provided by both
  • Differentiate between kubernetes and docker container orchestration systems

How Kubernetes Helps Manage Containerized Applications

Codecademy Team
May 19, 2023

If you’re a Back-End Developer or Full-Stack Developer, you may already be familiar with containerized applications. For those who aren’t: Containerized apps come with all the code, files, and packages they need to run properly on any device, and they’re especially popular with Agile and DevOps teams.

But how can an application run on hundreds or thousands of containers without causing problems? And when one container fails, why doesn’t the whole program crash?

The answer is Kubernetes. If you haven’t heard of it before, no problem. Ahead, we’ll walk you through the basics of what Kubernetes is and how it helps developers seamlessly manage huge containerized applications.
