Final answer:
Amazon Route 53 is a DNS service that does not perform domain registration but provides load balancing and health checks for resources.
Step-by-step explanation:
Amazon Route 53 is a fully managed DNS (Domain Name System) web service offered by Amazon Web Services (AWS). It does not perform domain registration as this is a separate service. Route 53 provides DNS service, allowing users to manage domain names and map them to IP addresses.
In addition to DNS service, Route 53 also performs load balancing, allowing users to distribute traffic to multiple resources such as EC2 instances, S3 buckets, ELB load balancers, and more. It also offers health checks, which regularly monitor the health of resources and route traffic away from any unhealthy endpoints.
