OPS705 Assignment 2

Revision as of 20:20, 29 March 2023 by Chris.johnson (talk | contribs) (Subnets)

In this assignment, you will install a WordPress blog in AWS using Elastic Beanstalk and RDS. You will construct this assignment in our AWS Academy Learner Lab classroom.

Unlike labs, assignments have minimal instructions. You are given specifications on what the assignment needs, and you must rely on your previous work in the course. If the assignment doesn't have the command you need, you can find it in your labs. As with Assignment 1, don't be afraid to do a little research!

Assignments in OPS705 are built as an assessment of your ability to meet the course objectives.

Task 1: Networking

In this task, you will create all the networking required for your new web application.

Virtual Private Cloud
