What type of technology is commonly used for load balancing in cloud environments?

The technology commonly used for load balancing in cloud environments is DNS. DNS, or Domain Name System, can distribute traffic across multiple servers by resolving the domain name to different IP addresses, effectively balancing the load based on defined policies. This method can enhance fault tolerance, optimize resource utilization, and improve response times by directing users to the nearest or least busy server.

In cloud environments, effective load balancing is crucial for ensuring that no single server becomes overwhelmed with requests, thereby maintaining service availability and performance. By leveraging DNS for load balancing, organizations can route client requests intelligently across various servers, depending on factors like geographical location or current server load.

While DRS (Distributed Resource Scheduler) is related to resource distribution in virtualized environments, it does not specifically pertain to load balancing in the same capacity as DNS. A CDN (Content Delivery Network) is designed primarily for delivering content quickly and efficiently but is not the core technology for load balancing. HTTP, being a protocol, does not inherently provide load balancing functionality either.
