Introduction

Route 53 offers two main services: domain registration and domain hosting. Route 53 is a globally resilient service as the name servers are distributed globally and have the same datasets across all the servers. So, even if a region is affected by outages, Route 53 will still function.

This section will begin with an overview of the Domain Name System (DNS), providing a solid understanding of its role in internet communication. Then, we will explore the registration and hosting of a domain using Route 53. Additionally, we will explore the key functionalities of Route 53, including routing policies, health checks, and the management of hosted zones.
