Note: Below is a translation of the article Client Side Load Balancing for Web 2.0 Applications , which addresses the issues of load balancing between multiple servers and discusses a solution that balances this load directly on the client’s computer.
The server handles HTTP ( HyperText Transfer Protocol ) requests from browsers. If you enter a URL in the address bar, for example, www.digital-web.com , your computer will send a search request to determine which servers will process your request and send data. The technique for handling such requests for a cluster of web servers is called load balancing.
Load Balancing for Web Applications
')
Load balancing improves website reliability by distributing requests among multiple (cluster) servers if one of them is overloaded or failed. There are many methods to ensure this behavior, but they all must meet the following requirements:
Distribute the load within the cluster of working servers.
Correctly handle the failure of one of the working servers.
The entire cluster must exist for the end user as one single machine.
