Cloud Computing Basics

Six Major Advantages:

  • Less need for upfront capital, you pay for what you use
  • Share the costs with other customers, and benefit from that scale
  • No need to guess capacity
  • Launch resources in minutes
  • Maintaining and running data centers is a thing of the past.
  • Go global in minutes

"Let's See Nelly Loofah Massive Goats"

Setup

  1. Navigate to new account page and fill in information (AWS account name can be changed later on)
  2. If you so choose, navigate to IAM and modify the sign-in link to something a bit more user-friendly
  3. (optional) Set up billing alerts as needed in account preferences and CloudWatch
  4. Enable MFA for the account
  5. Setup individual users in IAM: Mgmt console should be enough for non-programmers or services that don't use the CLI, SDK, etc.

Organizations

  • This feature allows you to manage billing, access, compliance, security, and share resources amongst your accounts.
