While dependable internet connectivity has become imperative, it is load balancing that helps in achieving a greater bandwidth. Load balancing helps distribute workload over two or more servers in order to achieve increased redundancy, scalability or security. It has specific significance in busy networks, especially when it is challenging to predict the number of requests that will be issued to a server. While it not only increases the performance of servers, load balancing leads to their optimal utilization while also ensuring that no particular server is burdened. Load balancing spreads the work of your managed server among two or more servers, optimizing resources, and output and response times. If a server fails in any way, requests are routed to other servers as per a predetermined standard to eliminate downtime. In load balancing, security is always important. Load balancers normally bring with them the added benefit of hiding the network and servers that are behind the scenes doing the actual work for the requested service. Requesting a map service from one URL (the load balancer) may actually be assembled from many different servers that were behind a firewall. Since only the load balancer is allowed to communicate through the firewall security is increased as there would only be one point of entry. Some load balancers also come equipped with some analysis capabilities to detect denial of service attacks and take preventative measures. With the increase in the size of an enterprise, there is an increase in the strain on the databases, network servers, and other crucial areas. Especially effective for organizations that use multiple data centers and server farms, load balancing solutions monitor the workload of servers and help to direct users. Distributing the work load is important but being able to automatically detect and handle the failure and the recovery of back-end servers is crucial. Load balancers offer many different capabilities in this area. While some can only detect if the server is alive and on the network, others have very elaborate methods such as retrieving content from pre-determined web pages. Depending on the hardware and organizational needs, it's important to speak with a reputable provider about implementing and customizing this solution to your needs. Each network faces different challenges and works within different constraints. Look for a service provider who can leverage parallel multi-core processing to cost-effectively drive industry-leading performance across a rich server load balancing and application acceleration feature set for unmatched total value of ownership.
