What is redundancy and load balancing?

In short redundancy is a relative choice and should be decided based on criticality and affordability. Load balancer is usually configured to distribute traffic based on round robin algorithm to all the healthy and connected nodes. It also does a health check at regular intervals to keep a track of healthy nodes.

What is load balancing in network?

Load balancing is defined as the methodical and efficient distribution of network or application traffic across multiple servers in a server farm. Each load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to any available server capable of fulfilling them.

What is network load balancing and failover?

The Network Load Balancing (NLB) feature distributes traffic across several servers by using the TCP/IP networking protocol. By combining two or more computers that are running applications into a single virtual cluster, NLB provides reliability and performance for web servers and other mission-critical servers.

What is redundancy in network?

Network redundancy is the process of adding additional instances of network devices and lines of communication to help ensure network availability and decrease the risk of failure along the critical data path.

What is redundant load?

A member is considered load path redundant if an alternative and sufficient load path is determined to exist. The alternative load paths must have sufficient capacity to carry the load redistributed to them from an adjacent failed member.

Where is network load balancer used?

Best use cases for Network Load Balancer: When you need to seamlessly support spiky or high-volume inbound TCP requests. When you need to support a static or elastic IP address. If you are using container services and/or want to support more than one port on an EC2 instance.
