Load Balancer as a Service Explained in Detail

    Load Balancer as a Service

    Load balancing is the appropriate distribution of incoming traffic across a bunch of servers. This way it ensures that no one particular server is overloaded and thus performs with maximum efficiency.

    Now load balancer as a service is the availing of this service via 3rd party providers over the cloud.

    How Does Load Balancing as a Service Work?

    Load balancing as a service would mean that the provider would use a predetermined pattern for the distribution of traffic load.

    An application or a web browser would receive a request from the user’s end and fulfill that would try to connect it with a server.

    Now the load balancer, working on a set pattern would divert this request to an appropriate server.

    Then the server also responds back to the browser (or an application) with the help of the load balancer.

    The load balancer also pitches in by taking over the compute-intensive process of decrypting SSL encrypted data.
