How does AWS Route 53 work?

Last updated on September 25, 2022 @ 6:32 pm

AWS Route 53 is an Amazon Web Services public cloud DNS service. Route 53 manages and distributes DNS requests for millions of customers across the world.

It can be used to resolve DNS queries for domains that are not hosted on AWS, as well as to power DNS resolution for AWS services.

Route 53 uses a combination of a DNS server and a database to store DNS records. DNS server instances act as the authoritative source of DNS data for the Route 53 zone. Route 53 also uses a database to store DNS records for both A records and MX records.

When a DNS request is received, Route 53 checks the database to see if the requested record exists. If the record is found, Route 53 returns the hostname or IP address for the requested record.

PRO TIP: AWS Route 53 is a DNS (domain name system) service that can be used to route end users to internet applications by translating human-readable domain names, such as example.com, into IP addresses. However, because Route 53 is a DNS service, it can also be used to route end users to other types of resources, such as an Amazon S3 bucket or an Amazon EC2 instance. When you create a Route 53 record, you specify the values that you want Route 53 to return when a DNS query matches the record.

Route 53 also has the ability to handle large numbers of DNS requests. It has been reported that Route 53 can handle more than 1 million DNS requests per second.

Route 53 can also handle requests for multiple hostnames or IP addresses at the same time. This allows Route 53 to be used to resolve DNS queries for domains that are not hosted on AWS.

Route 53 is a valuable tool for both small and large businesses. It can be used to power DNS resolution for AWS services, as well as to resolve DNS queries for domains that are not hosted on AWS.

Route 53 also has the ability to handle large numbers of DNS requests.
