Module 9 – Guided Lab: Creating a Highly Available Environment
Lab overview and objectives
Critical business systems should be deployed as highly available applications—that is, applications remain operational even when some components fail. To achieve high availability in Amazon Web Services (AWS), we recommend that you run services across multiple Availability Zones.

Many AWS services are inherently highly available, such as load balancers. Many AWS services can also be configured for high availability, such as deploying Amazon Elastic Compute Cloud (Amazon EC2) instances in multiple Availability Zones.

In this lab, you will start with an application that runs on a single EC2 instance. You will then make the application highly available.

After completing this lab, you should be able to:

Inspect a provided virtual private cloud (VPC)
Create an Application Load Balancer
Create an Auto Scaling group
Test the application for high availability
