AWS Route53

Amazon Route 53 is a highly scalable and reliable Domain Name System (DNS) service provided by Amazon Web Services (AWS). It helps route end users to internet applications by translating human-readable domain names, such as www.example.com, into the IP addresses that computers use to identify each other on the internet. Route53 can be used for both public & private domain names as well

In Route 53 most common records are:

• A: maps the hostname to the IPV4 address
• AAAA: maps the hostname to the IPV6 address
• Cname: maps one hostname to another hostname (Non-root domain)
• Alias: maps a hostname to the AWS resource (both root & non -root domain)
• MX: specifies the mail servers responsible for receiving email messages for a domain.

Features of Route53

• Load balancing
• Health checks
• Routing policy

Routing Policies:

Simple Routing policy: A simple routing has one record with multiple IP addresses. In this routing policy, we cannot attach health checks. if multiple values are returned a random one is chosen by the client.

Weighted routed policy: This policy is used to handle the requests based on the percentage (%) that go to a specific endpoint. It is mainly helpful to test any new app versions, in simple terms split traffic requests.

Latency routing policy: The latency routing policy in Route 53 is a DNS routing method that helps improve the performance of web applications by directing users to the AWS region with the lowest latency or fastest response time. super helpful when the latency of users is a priority.

Failover routing policy: The failover routing policy in Amazon Route 53 is used to route traffic to a standby resource (such as a backup server) when the primary resource becomes unavailable. This helps ensure high availability and continuity of service for critical applications. (active/passive)

Multi-value routing policy: Multivalue routing is a routing policy provided by Amazon Route 53, which allows you to configure multiple values for a single DNS record. Each value represents a different IP address or endpoint for the same resource, and Route 53 will randomly respond to each DNS query with a different IP address from the configured set of values. This can be useful for load-balancing traffic across multiple resources or for providing fault tolerance by directing traffic to healthy resources if some of them become unavailable.
