Should I Use Load Balancer

For this reason, load balancers are essential to balancing the traffic and making sure that new sessions are brought to servers with adequate spare capacity so that overloaded servers can process their backlog successfully and then be returned to the pool of resources available for new sessions.

Why do we need NLB?

Network Load Balancer (NLB) should be used to balance Layer 4 traffic across multiple services. It’s the only AWS LB that supports fixed IP addresses with the use of Elastic IPs (EIP) and can provide the best throughput operating at Layer 4.

Why load balancing is important in a modern network design?

Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overload of any single resource. Using multiple components with load balancing instead of a single component may increase reliability and availability through redundancy.
