Lesson Recap

• Regions
• Availability Zones (AZs)
• Virtual Private Clouds (VPCs)
• AWS VPC Networking

There are many tools and capabilities at your disposal with Regions, AZs, VPCs and AWS networking. Most things that are possible in an in-house network are available in AWS. These functions allow you to have flexibility and security as well as global reach.

Lesson Objectives

You will be able to:

• Build on the AWS global infrastructure
• Take advantage of the multiple availability options AWS provides
• Build multiple AWS VPCs to suit requirements
• Create custom isolated networks to meet business needs
