Understanding load balancing algorithms
Load balancing algorithms help ensure efficient processing, and they are a fundamental component of cloud computing. At ReliaCloud, we provide several load balancing algorithms that each use a different technique to balance traffic across the cloud servers.
Clients can select the appropriate algorithm to fit their needs. For example, the “roundrobin” algorithm is the smoothest and fairest algorithm when the cloud server’s processing time remains equally distributed. Round robin is also the most commonly used load balancing algorithm.
When very long sessions are expected – such as LDAP, SQL or TSE, “leastconn” may be the most suitable algorithm. Leastconn ensures that the server with the lowest number of current connections receives the connection.
When the “source” algorithm is used, the source IP address is hashed and divided by the total weight of the running servers to designate which server will receive the request. This ensures that the same client IP address will always reach the same server as long as no server goes up or down.
