AWS Route 53

Amazon Route 53 is the DNS service provided by AWS and is one of the most well known, reliable and cost-effective services for managing domains.

Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. It is designed for developers and corporates to route the end users to Internet applications by translating human-readable names like www.mydomain.com, into the numeric IP addresses like 192.0.2.1 that computers use to connect to each other.

Easy to register your domain − We can purchase all levels of domains like .com, .net, .org, etc. directly from Route 53.

Highly Available and Reliable− Route 53 is built using AWS infrastructure. Its distributed nature towards DNS servers help to ensure a consistent ability to route applications of end-users.

Scalable − Route 53 is designed in such a way that it automatically handles large volume queries without the user’s interaction.

Designed to Integrate with Other AWS Services− Route 53 also works with other AWS services. It can be used to map domain names to our Amazon EC2 instances, Amazon S3 buckets, Amazon and other AWS resources.

Easy to use − It is easy to sign-up, easy to configure DNS settings, and provides quick response to DNS queries.

Health Check - Route 53 monitors the health of the application. If an outage is detected, then it automatically redirects the users to a healthy resource.

Cost-Effective − Pay only for the domain service and the number of queries that the service answers for each domain.

Secure − By integrating Route 53 with AWS (IAM), there is complete control over every user within the AWS account, such as deciding which user can access which part of Route 53.

There are several types of routing policies. The below list provides the routing policies which are used by AWS Route 53.

Simple routing responds to DNS queries based only on the values in AWS route table. Use the simple routing policy when you have a single resource that performs a given function for your domain.

If an application is hosted on EC2 instances in multiple regions, user latency can be reduced by serving requests from the region where network latency is the lowest. Create a latency resource record set for the Amazon EC2 resource in each region that hosts the application. Latency will sometimes change when there are changes in the routes.

Geolocation routing can be used to send traffic to resources based on the geographical location of users, e.g., all queries from Canada can be routed to the IP address 10.20.30.40. Geolocation works by mapping IP addresses, irrespective of regions, to locations.

Amazon Route 53 currently supports the following DNS record types:

A (IPv4 address record)

AAAA (IPv6 address record)

CNAME (Canonical Name record)

CAA (Certification authority authorization)

MX (Mail Exchange record)

NAPTR (Name authority pointer record)

NS (Name server record)

PTR (Pointer Record)

SOA (Start of Authority record)

SPF (Sender policy framework)

SRV (Service locator)

TXT (Text Record)
