Static Load Balancing

Advantage:

1. Simplicity: Static load balancing is less complicated to enforce and manipulate. The constant configuration makes it less complicated to installation and keep.
2. Predictability: In environments with consistent and predictable workloads, static load balancing can perform well since it distributes traffic based totally on a predetermined configuration.
3. Lower Overhead: Static load balancing commonly incurs lower computational overhead because the distribution of traffic is fixed and does now not require continuous tracking or changes.

Disadvantages:

1. Inflexibility: It lacks adaptability to changing conditions. Sudden increases in traffic or changes in server capacities can lead to suboptimal useful resource utilization.
2. Risk of Overloading: If the workload distribution isn’t always well-balanced to begin with, there may be a threat of overloading certain servers while others remain underutilized.
3. Limited Fault Tolerance: Static load balancing may additionally struggle to deal with server failure, as it does not dynamically adjust to change in the availability of resource.

A load balancer is a device that acts as a reverse proxy and distributes network or application traffic across a number of servers. Load balancing usually involves dedicated software or hardware, such as a multilayer switch or a Domain Name Service server process.

Load Balancing can be classified into two types based on the behavior of the algorithm:

• Static Load Balancing: Static load balancing is the method of dividing the incoming load on a server using algorithms that have prior information about the existing servers in the distributed network. These load balancing schemes have a pre-defined load schedule that determines a fixed amount of load that can be shed on other systems.
• Dynamic Load Balancing: It is a more versatile scheme of load balancing which can dynamically identify the amount of load that needs to be shed during runtime and which system should bear the load.
