Learn how to build and run AWS workloads with the most effective use of AWS services (compute, networking, storage, serverless) and resources to achieve enterprise-grade business outcomes with the lowest operating cost.

In this lab scenario, you'll learn how to optimize an already deployed and running web application. The existing web application contains several configurations that should be optimized to achieve better performance, availability, scalability, and improvements in overall operating cost.

Note: To keep things simple and to quicken the lab launch time, all AWS networking and compute resources provisioned within this lab take place in the publicly zoned area of the default VPC, and as such the security posture is limited and should not be replicated in your own production environments.

Learning Objectives

Upon completion of this lab, you will be able to:

• Cloud optimize an existing AWS web application

Intended Audience

• Those interested in learning how to optimize AWS architectures to be more performant, scale on-demand, and minimize running costs

Prerequisites

Familiarity with the following will be beneficial but is not required:

• Be comfortable with basic Linux command line administration

Lab Environment

This lab will start with the following AWS resources provisioned automatically for you:

• 1 x EC2 t3.small instance (hashgen.cloudacademy.platform.instance):
  • Configured as an NFS server
  • Runs a cronjob to generate a hash which is written into an NFS share
• 1 x ASG containing a static set of:
  • 2 x EC2 t3.small instances (app.cloudacademy.platform.instance)
    • Each instance mounts to the NFS share for read-only purposes
• 1 x ALB
  • Listener (port 80)
  • App Target Group (port 8080)

To achieve the lab end state, you will be walked through the process of:

• Using your local workstation browser to remotely connect to the AWS Console
• Within the AWS Console perform several cloud optimization configurations to improve:
  
  • Performance
  • Availability
  • Scalability
  • Operating Cost
