Introduction 

Amazon Route 53 is a cloud Domain Name System (DNS) web service that is highly accessible and scalable. Service. Which gives developers and businesses an extremely reliable and cost-effective way to route end users to Internet applications by translating names like www.abc.com into the numeric IP addresses like 192.0.3.2 that computers use to connect.

Amazon Route 53

Amazon Route 53 enables developers to manage the IP addresses, known as "records," listed in the DNS phone book for domain names. Amazon Route 53 responds to requests, known as "queries," to translate domain names into IP addresses.

Developers can use Domain Name Registration to purchase and manage domain names, and Amazon Route 53 will automatically configure DNS settings for those domains. The Route 53 API or the AWS Management Console can configure DNS settings. This service can be used to set up DNS "health checks" to monitor the health of resources and applications and route traffic to healthy endpoints.

Amazon Route 53 may be linked with AWS Identity and Access Management (IAM) to manage rights and credentials for all users in your AWS account, providing additional protection.

With Amazon Route 53, users only pay for managing domains and the number of queries the DNS service answers for each domain.

What are the different routing policies available in Route 53?

Simple routing policy

This is one of the most basic types of routing. A response to DNS requests constitutes simple routing. Based on the AWS route table grades. Furthermore, it's perfect when you require a single resource to do a specific task for the domain in question.

                                               Source - link

Weighted

 You can use this to assign weights to resource record sets. For example, you can specify 25 for one resource and 75 for another, which means 25% of requests will be routed to the first resource, and 75% will be routed to the second.

LBR (Latency-based routing)

Latency Routing Policy is used when there are multiple resources for the same functionality. If DNS requests are sent to Route 53, you want it to answer with answers that provide the best latency, i.e., the region that will give the fastest response time.

Failover

Traffic can be directed to a server that has been designated as the primary server using Failover Routing Policy. However, keep in mind that the routing will only operate if the server is in good condition. If the health checks reveal that the primary server fails, traffic is diverted to a designated backup resource.

Geolocation

This allows you to balance the load on your resources by routing requests to specific endpoints based on their geographic origin.

Multivalue answer

Use this option when you want Route 53 to answer DNS queries with up to eight healthy records chosen at random.

Amazon Route 53 Traffic Flow enables you to manage traffic globally using a variety of routing types, such as Latency Based Routing, Geo DNS, Geoproximity, and Weighted Round Robin, all of which can be combined with DNS Failover to enable a variety of low-latency, fault-tolerant architectures. You can easily control how your end-users are directed to your application's endpoints using Amazon Route 53 Traffic Flow's simple visual editor, whether in a single AWS region or globally. Amazon Route 53 also provides Domain Name Registration, which allows you to buy and manage domain names like example.com, and Amazon Route 53 will automatically configure DNS settings for your domains.

How to configure Amazon Route 53?

The steps for configuring Route 53 are as follows.

Step 1:  Now, search Route 53 in the search bar in the AWS Console.

Step 2: In the upper left corner of the page, the navigation bar and select Create Hosted Zone.

Step 3: A form page appears. Provide the necessary information, such as the domain name and comments. And click the Create button.                                            

Step 4: The domain's hosted zone will be created. There will be four DNS endpoints known as delegation sets, and these endpoints must be updated in the domain's Nameserver settings.

Step 5: If it's godaddy.com, navigate the domain's control panel and update the Route 53 DNS endpoints. Remove the remaining default values. It will take approximately 2-3 minutes to update.

Step 6: Return to the Route 53 console and select the option for go-to record sets. This will display a list of record sets. There are two record sets by default: NS and SOA.

Step 7: Select the Create Record Set option to begin creating your recordset. Fill the blanks with details like Name, Type, Alias, TTL seconds, Value, Routing policy, etc. Save the record set by clicking the Save button.

Step 8: Create another record set for a different region. Create two recordsets with the same domain name but pointing to different IP addresses using your chosen routing rules.

Once completed, user requests will be routed following network policy.

Frequently Asked Questions

What is Amazon Route 53?

Amazon Route 53 connects user requests to AWS infrastructures, such as Amazon EC2 instances, Elastic Load Balancing load balancers, Amazon S3 buckets, and infrastructure outside of AWS.

Why is it called Route 53?

AWS Route 53 is derived from Port 53, which handles DNS for TCP and UDP traffic requests; the phrase Route could relate to routing or a standard highway naming convention.

What is DNS?

The DomainName System (DNS) turns domain names into IP addresses, which browsers use to load internet pages.
