AWS Tutorial: AWS Connectivity

Welcome to the AWS Connectivity lesson. Once you have a VPC, you need a secure way for your corporate office (on-premises data center) to connect to it.

AWS Direct Connect vs VPN

Why Learn AWS Connectivity?

Most large enterprises run "Hybrid Cloud" architectures, meaning they use both their own data centers and AWS simultaneously. You must know how to link these two environments securely and reliably.

Tutorial Overview

In this tutorial, you will learn the two main ways to connect a corporate data center to an AWS VPC:

Connecting On-Premises to AWS

  1. AWS Site-to-Site VPN: This establishes a highly encrypted connection between your corporate office and your AWS VPC over the public internet. It is quick to set up and very cost-effective, but because it traverses the public internet, bandwidth and latency can occasionally fluctuate.
  2. AWS Direct Connect (DX): This establishes a dedicated, completely private fiber-optic network connection from your office straight to AWS. It entirely bypasses the public internet. It takes weeks to physically install and is very expensive, but it offers ultra-fast, perfectly consistent network performance (up to 100 Gbps).
