Advanced Load Balancer

Introduction:

The load balancer distributes incoming service requests among multiple servers in such a way that the load distribution is transparent to users. Load balancing helps achieve optimal resource use, maximizing throughput, minimizing response time, and avoiding overload.

Components of Advanced Load balancer:

• Virtual Services

  o Abstract of an application service, represented by a unique combination of IP, port, protocol and application profile such as TCP or UDP. A virtual service advertises an IP address and ports to the external world and listens for client traffic.

• Pools

  o Pools maintain the list of servers assigned to them and perform health monitoring, load balancing, persistence.
