Software Load Balancers
Software load balancers are applications or components that run on general-purpose servers. They are implemented in software, making them flexible and adaptable to various environments.
- The application chooses the first one in the list and requests data from the server.
- If any failure occurs persistently (after a configurable number of retries) and the server becomes unavailable, it discards that server and chooses the other one from the list to continue the process.
- This is one of the cheapest ways to implement load balancing.
Types of Load Balancer
Load Balancers distribute incoming network traffic across multiple servers to ensure optimal resource utilization, minimize response time, and prevent server overload. When it comes to load balancing, three primary types exist: software load balancers, hardware load balancers, and virtual load balancers.
