Difference Between Load Balancing and Load Sharing in Distributed System
A distributed system is a computing environment in which different components are dispersed among several computers (or other computing devices) connected to a network. These devices broke up the work and coordinated their efforts to do the job faster than if it had been assigned to a single device.
Load balancing is the practice of spreading the workload across distributed system nodes in order to optimize resource efficiency and task response time while avoiding a situation in which some nodes are substantially loaded while others are idle or performing little work.
Load balancing solutions are designed to establish a dispersed network in which requests are evenly spread across several servers. Load sharing, on the other hand, includes sending a portion of the traffic to one server and the rest to another.
Differences between Load Balancing and Load Sharing:
|Load Balancing||Load Sharing|
Load balancing equally distributes network traffic or load across different channels and can be achieved using both static and dynamic load balancing techniques.
Load sharing delivers a portion of the traffic or load to one connection in the network while the remainder is routed through other channels.
focuses on the notion of traffic dispersion across connections.
works with the notion of traffic splitting across connections.
The creation of Ratios, Least connections, Fastest, Round robin, and observed approaches are used in load balancing.
Load Sharing is based on the notion of sharing traffic or network load among connections based on destination IP or MAC address selections.
It is unidirectional.
it is unidirectional.
no instance is load sharing.
All instances are load sharing.
Accurate Load Balancing is not an easy task.
Load sharing is easy compared with load balancing.
Load sharing is a more specific phrase that refers to the distribution of traffic across different routes, even if in an uneven manner. If you compare two traffic graphs, the two graphs should be almost same with load balancing, however they may be comparable with load sharing, but the traffic flow pattern will be different.
