Amazon Route 53 is a Domain Name System offered by Amazon. Domain Name System is a hierarchical and decentralized naming system used to identify computers reachable through the internet or other internet protocol networks. Simply put, it is the phonebook of the internet. 
Route 53 is Amazon's highly available and scalable domain name system that provides secure and reliable routing of requests, both for services within AWS and infrastructure that is outside of AWS. Route 53 is able to provide this service through its global network of authoritative DNS servers that reduce latency and can be managed via the management console.
Amazon Route 53 effectively connects user requests to infrastructure running in AWS such as Amazon EC2 instances, Elastic Load Balancing load balancers, or Amazon S3 buckets and can also be used to route users to infrastructure outside of AWS. You can use Amazon Route 53 to configure DNS health checks, then continuously monitor your applications’ ability to recover from failures and control application recovery with Route 53 Application Recovery Controller.
Some of the components used within Amazon Route 53 are;
**Hosted Zone**- A hosted zone is a container that holds information about how you want to route traffic for a domain registered within Aws. Route 53 supports Public and Private hosted domains

**Resolver** - Use the Resolver feature of Route 53 for your Virtual Private Clouds (VPC) which integrates easily with DNS on your network. To get started, configure endpoints for DNS queries into and out of VPCs that you created with Amazon Virtual Private Cloud(VPC).
**DNS Firewall**- this is a managed firewall service for queries that originate in your Virtual Private Clouds.
**Application Recovery Controller** - The application Recovery Controller allows you to check whether your resources are ready for recovery. It can be done by checking if an application in a region is ready for recovery or checking the status of each resource type across regions. You can also use the Application Recovery Controller to manage failovers by using routing controls integrated with health checks.
 
Some benefits of Route 53 are;
1. It is highly available and reliable
2. It is flexible
3. It is designed for use with other AWS services.
