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.

Benefits of Load Balancer as a Service

1.    Cost-Effective

Load balancing as a service is usually cheaper than the traditional methods of handling your incoming traffic.

In addition to being cheaper, it is simpler to implement as well.

2.    Increased Stability

Load balancing as a service operating over a cloud makes it a more stable solution for handling app or website traffic.

Cloud enables it to redistribute the traffic over different servers and devices with that much more ease.

3.    Continuity of Operations

Making sure your website/app holds up at all times is pretty critical for any business.

It might so happen that on certain occasions that a server goes down (for whatever reason there might be) and therein a load balancer is so much helpful.

The load balancer would very quickly switch over the load to one of the other running servers.
