It provides developers with an efficient and extremely reliable way to connect users to internet applications without any downtime, it still has downtime in servers or applications but users/customers may not be aware of it. It effectively connects user requests to AWS such as Amazon EC2 instances, Elastic Load Balancing, or Amazon S3 buckets. AWS Route 53 mainly performs three functions:-
- It registers the name for the website (Domain name) which needs a name. Like if you want to buy a domain name, you that domain name through Route 53.
- It helps the user to connect the website or web application with the browser in the server when he/she enters the website name.
- It keeps checking the health of resources before the customer notices it by sending an automated request over the internet to resources.
Benefits Of Using Amazon Route 53

Types Of Routing Policies
1. Simple Routing:- It allows configuring DNS with no unique Route 53 Routing. It is mainly used when you have a single resource that performs a given function for your domain.
2. Failover Routing:- It routes traffic to another or alternate resource when the previous resource is unhealthy. It makes one ELB (Elastic Load Balancing) on active mode and the other on standby mode. It switches automatically when there is a failover.3. Geolocation Routing:- It routes the resources based on the geographic location of the users. It localizes the content or website in the language of the user. These are specified by continent, or by country.
4. Geoproximity Routing:- It routes traffic to the resources based on the geographic location of users and their resources based on the geographic location of users and their resources. There is an option available to route less traffic or more to a given resource.
5. Latency-based Routing:- It is mainly used when we have installed or hosted a website across multiple AWS regions. It improves the performance by serving their request from the lowest latency AWS region.
6. Weighted Routing:- It routes multiple resources with a single domain name and controls the traffic to be routed to each resource. It is mainly useful for testing and load-balancing new versions of the software.

Key Features Of Route 53
- Traffic Volume: According to your application’s geolocation, latency, health, and other factors, you can direct end users to the optimal endpoint available.
- Routing based on Latency: End users can be directed to the AWS region with minimal latency.
- A Geo DNS: Your end users might be directed to an endpoint that is situated in their particular area or the closest geographical place.
- Failover DNS: In order to prevent website crashes or outages, you might direct your end customers to a different location.
- Health Monitoring and Checks: Amazon Route 53 keeps an eye on your website’s or application’s health and performance. You may also keep an eye on your servers.

Limitations of Amazon Route 53
Even though it is a sophisticated DNS service with many useful capabilities, Amazon Route 53 has a number of significant limitations. The most crucial are as follows:
DNSSEC is not supported. It is not possible to use DNSSEC on AWS Route 53. DNSSEC is able to thwart man in the middle (MITM) attacks and other kinds of DNS attacks.
a single point of failure. When combined with other AWS services, AWS Route 53 could form a single point of failure. AWS Route 53 disaster recovery and associated problems are a result of this.
Price of Route 53. The service is pricey, especially for enterprises using Route 53 with non-AWS endpoints/services. Particularly pricey are the inquiries for each record type to which you apply a query, which is an additional $50/month for the visual editor.
Optional forwarding. AWS Route 53 does not offer conditional forwarding or forwarding for domains used on an on-premises network. DNS load balancing for Route 53 only.
Only minimal load balancing functions are offered by AWS Route 53 load balancer features, which lack enterprise-class functionality and comprehensive policy support.

Step 6:-To create your record select the record name and click on the create record option.
Step 7:− Fill in all the required details such as Name, Type, Alias, TTL seconds, Value, etc. Click the Create Record option. Create one more record for some other region so that there will be two records with the same domain name pointing to different IP addresses with your selected routing policy.
When completed, the request of the user will be routed based on the network policy.
