Amazon Route 53

Amazon Route 53 is a web service which is a highly scalable and available Domain Name System (DNS). This is accomplished by translating domain names (www.apponix.com) into IP addresses which is how computers connect.

Functions of Route53

Domain Registration:

This allows the user to create public DNS records. Users can also manage the IP address available for user’s domain names in the Internet’s DNS record.

Domain Name System (DNS)service:

Route53 translates domain names like www.apponix.com into IP addresses like 192.0.1.2. It responds to request via a network of DNS servers. Users can use Route53 to create records for a new domain or to transfer DNS records for an existing domain.

Health Checking:

Route53 monitor the health of user’s application, web servers and other resources. Route53 periodically sends requests to the endpoint to verify that it is functional, available and reachable.

Benefits of Amazon53

Route53 provides several benefits. They are:

Simple
Flexible
Reliable and Highly Available
Fast
Cost-effective
Scalable
Secure
Designed to Integrate with Other AWS Services

Simple:

User’s DNS requests are answered by Route53 in AWS within minutes and it’s a self-service sign-up Users can simple AWS Route 53 API and embed it in web applications too.

Flexible:

Amazon Route53 provides users flexibility in choosing traffic policies based on different criteria such as latency, geographic location, and endpoint health.

Reliable and Highly Available:

Aws Route53 is designed and built using AWS's reliable and highly available infrastructure. DNS servers are distributed across many availability zones which helps in routing to websites consistently by end-users.

Fast:

Distributed servers around the world make a low-latency service because of Rooute53, route users to the nearest DNS servers available.

Cost-effective:

AWS follows the Pay-as-you-go model so users can pay for what you use. For example, the hosted zones are managing the number of queries and user’s domains, etc., Optional features like health checks and traffic policies are available at very low cost

Scalable:

When the query volume size varies, Amazon Route53 is designed to automatically scale up or down.

Secure:

Users can create and grant permission and unique credentials to every user with the AWS account. Designed to Integrate with Other AWS Services Amazon Route53 works well with other services like Amazon s3 and Amazon EC2

For Example, Route53 can be used to domain names or IP addresses to Amazon S3 buckets and Amazon EC2 instances.

AWS Routing policies

Below are the routing policies which are used by AWS Route53 are:

Simple Routing
Latency-based Routing
Geolocation Routing

Simple Routing:

This type of routing responds to DNS requests based only on the values in AWS Route Table. When users have a single resource that performs a given function of a user-defined domain using a simple routing policy.

Latency-based Routing:

If an application is hosted in multiple regions on EC2 instances, user latency can be reduced by serving requests from the region where network latency is the lowest.

Geolocation Routing:

Geolocation routing can be used to send traffic to resources based on the geographical location of users.
