Step by Step Comprehensive Detailed Explanation

Amazon Route 53 can provide DNS failover capabilities and health checks to ensure the availability of SecureInfo Pvt. Ltd.’s website. Here’s how it works:

Health Checks: Route 53 performs health checks on the website to monitor its health and performance1.

DNS Failover: If the primary site becomes unresponsive, Route 53 can automatically route traffic to a healthy backup site1.

Regular Examination: The health checks can be configured to run at regular intervals, ensuring continuous monitoring of the website’s availability1.

Traffic Routing: Route 53 uses DNS failover records to manage traffic failover for the application,

directing users to the best available endpoint1.

Reference: Amazon Route 53 is a scalable and highly available Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost-effective way to route end users to Internet applications by translating human-readable names like www.example.com into the numeric IP addresses like 192.0.2.1 that computers use to connect to each other1. Route 53 is fully compliant with IPv6 as well1.
