Virtualisation Basics

In previous rooms, you learned what the components of a computer are and how they communicate with each other. In this room, you will learn how companies have optimized these computer components to reduce costs and build flexible, scalable systems that power the modern internet through a concept known as virtualization.

Have you ever considered how expensive and inefficient it would be if every piece of software or every website required its own physical server? 
Virtualization was created to solve exactly this problem.

Your manager asked for help on improving the hardware utilization of a computer that hosts a website. Let's explore the concept of virtualization and help your manager!

Learning Objectives

• Understand why managing applications on individual physical servers is inefficient.
• Learn how virtualization addresses hardware utilization and scalability challenges.
• Understand the components of a lab machine.
• Learn how containers have further optimized hardware utilization for applications.
