While chipping away at many facilitating foundations, I am regularly confronted with a difficult inquiry by numerous individuals of our customers: How can one balance Availability, Performance and Price? Upon first look, it is a mind boggling question. In any case, when separated, there are clear answers that are relevant for any circumstance.
Initial, a couple of definitions:

Execution: The speed at which an application will react to a client demand. Which means, can your organization handle a great deal of traffic?
Load balancing for a web application is an extraordinary instrument for both accessibility and execution. A Load Balancer remains before the web workers, making a virtual location to which the customer associates. It at that point circulates traffic equally preposterous workers to lessen the load on any single worker. On the off chance that one of the web workers is not accessible, the Load Balancer will identify the disappointment and reroute the traffic to the entirety of the leftover accessible workers. It likewise gives a layer of safety by concealing the genuine IP locations of the application workers.
Who Needs it:
- High transfer speed use locales.
- Sites with steady traffic where accessibility is critical
Load Balancers on a Tight spending plan
In the event that you should have a load balancer yet cannot actually bear the cost of a different apparatus load balancing software, there is programming accessible that will get the job done at a small portion of the cost. This arrangement is not pretty much as proficient or vigorous as the equipment arrangement, yet bears the cost of the advantage of accessibility and is superior to not utilizing a load balancer by any means.
Web Accelerators use innovations, for example, reserving and pressure to convey data to a huge client local area quicker. It mitigates tension on your framework by putting away data that in any case will be communicated more than once and conveying it directly from the store.
Who needs it:
- Heavy-traffic, database driven locales that convey web applications
- Sites with a worldwide crowd
SSL Accelerators, likewise like Load Balancers, remain before application workers.
