Answer from AI

Main types of load balancers:

  1. DNS-level load balancing — distributes requests among multiple IP addresses but does not consider server health and does not ensure even load.

  2. Hardware Load Balancers — specialized devices with high performance, support complex balancing algorithms and SSL termination.

  3. Software Load Balancers — e.g., Nginx, HAProxy. Flexible, easy to configure, support various algorithms (round-robin, least connections, IP-hash).

  4. Application layer (L7) load balancing — analyze the content of HTTP requests, can direct traffic based on URL, headers, etc.

  5. Transport layer (L4) load balancing — work with TCP/UDP, faster but less flexible.

The choice depends on performance requirements, flexibility, and application type.
