6 DNS and Load Balancing

Domain Name System (DNS) and load balancing are critical components of designing highly available and scalable cloud architectures. DNS allows domain names to be mapped to IP addresses so that computers can find each other on the internet. It functions as the address book of the internet. Amazon Route 53 is the AWS service for managing DNS and supports various routing policies and health checks to direct traffic. Load balancers distribute incoming requests across multiple servers/endpoints to prevent overloading any single resource. They ensure traffic is routed to healthy endpoints. Elastic Load Balancing (ELB) is the AWS-managed load balancing service and offers Classic, Application, Network, and Gateway load balancers ...
