All websites, computers, and linked gadgets use IP addresses to interact with one another. Since IP addresses are hard to remember, they are given domain names instead, which are often simple to remember and input into browser search bars. For instance, if Google’s IP address is 184.108.40.206 in IPv4 format, it would be simple to enter Google.com as the URL. A DNS service allows users to reach a website or target server by typing in a domain name and mapping IP addresses to domain names.
Through the use of a DNS service called AWS Route 53, Internet traffic is routed to the proper servers that are home to the requested Web application. Traditional DNS administration registers website domains and routes user queries to the hosting infrastructure. Amazon goes beyond this with their solution. Using the AWS Management Console, customers of the subscription-based AWS service may register domain names, implement routing policies, run infrastructure health checks, and manage configurations without coding. With a variety of AWS services, Amazon Route 53, in contrast to conventional DNS management services, allows scalable, flexible, secure, and managed traffic routing.
AWS Route 53 is named after Port 53, which manages DNS queries for TCP and UDP traffic. The word “Route” might relate to routing or even the well-known highway naming tradition. An authoritative DNS service called Route 53 provides data on the correspondence between IP addresses and domain names.
The AWS Route 53 service routes traffic between end users and the hosted Web apps as described in the following succinctly:
- Before configuring AWS Route 53 to direct Internet traffic to the servers hosting the domain name, the domain name must first be
- registered. Private cloud architecture and the AWS public cloud can be used as servers.
- The domain name or the whole URL is entered by end users into the browser’s search box.
- The DNS resolver, a programme that changes a domain name into an IP address, receives the request from the ISP.
- The user’s request is sent by the DNS resolver to a DNS root name server, which then routes it through a Top Level Domain (TLD) server before arriving at AWS Route 53.
- The DNS resolver receives the IP address of the domain name from the Route 53 name server.
- The DNS resolver may now redirect the user request to the relevant server hosting the content by the AWS Route 53 service parameters since it has the necessary IP address.
- The health of the backend servers is also checked by AWS Route 53. The DNS Failover service feature checks the endpoints for availability.
- Route 53 will divert traffic to a different healthy endpoint if the current endpoint is unhealthy. To alert the designated receiver of the required steps, an alarm will be set off using the AWS CloudWatch feature.
The following is a succinct summary of the current AWS Route 53 Features:
Resolver: The Route 53 Resolver may be used to resolve DNS issues between local networks and VPC. Users can use conditional setups to redirect DNS requests from AWS instances to a local network and forward DNS inquiries from the local network to a Route 53 Resolver. IPv4 and IPv6 formats are both supported by AWS Route 53.
Traffic Flow: Intelligent traffic routing that considers essential factors like distance, endpoint health, and latency, among others.
Geo DNS and Latency-Based Routing: By routing traffic from servers nearest to end users, latency is reduced, and the end-user experience is improved.
Configure Route 53 to reply to DNS requests from private hosted VPC zones when using private DNS for Amazon VPC. As a result, the public networks are not exposed to the DNS resolution data.
Health Checks, Monitoring, and Failover: According to the provided specifications, Route 53 routes internet traffic to target instances that are in good health. The health-checking agents will direct traffic to healthy endpoints in the case of an outage. The CloudWatch metrics produced by the health check functionality can further trigger AWS Lambda functions to take the necessary remedial action.
Domain Registration: Users may register new domain names or transfer administration of existing domains to AWS Route 53 using the scalable DNS management service. This function streamlines management and billing for providing Web-hosted services.
S3 and CloudFront Zone Apex Support: Generate Custom SSL certificates without requiring complex setups or proprietary code. Since an additional proxy server is not needed to reach the backend servers,
Route 53 may respond to requests for root domains like example.com in the same way as the whole example.com URL scheme, thanks to Zone Apex support.
Integration of Amazon ELB: To increase service availability and performance, several AWS target instances can share the traffic load using AWS Elastic Load Balancing. Using AWS ELB, customers may provide their Web services more fault tolerance for healthy target instances in AWS and on-premise infrastructure resources.
Weighted Round Robin: A programme that allows programmers to control how frequently a DNS answer is sent back. This functionality is helpful for traffic balancing across target instances as well as service testing.
Users may see resources and carry out operational duties using a straightforward and intuitive administration panel. There is a mobile app available for the management console as well. Using the AWS Identity and Access Management service, users may further manage Route 53 controls, including the authorization to modify DNS records.
Amazon Route 53 has a significant advantage over its rivals thanks to its policy-based routing, health check and monitoring, support for bi-directional query resolution for hybrid cloud settings, and interaction with a wide range of AWS services. Users have better management and control over their internet traffic thanks to routing policies like Multi-Value Routing and Weighted Routing. A variety of AWS services required to execute apps hosted on the AWS architecture are compatible with Route 53. The tight integration of services enables customers to make changes to their architecture and scale resources to handle growing Internet traffic volumes without requiring a lot of DNS resolution, configuration, and maintenance.
