Improve Website Availability with Server Load Balancing
Recently IT infrastructure has gained prominence and playing an important role in the success of a
business organization. The brand image, reputation, market share and customer satisfaction that a
company generates depends to a huge extent on the continuous availability of the corporate
website. Today usually network servers are used for hosting eCommerce, ERP and other
applications. The eBusiness architecture is expected to provide high availability, performance and
secure and scalable solutions to help other applications every time.
There are situations when the application accessibility is obstructed by server/application failures
and network overloads. There are times when the resource utilization was out of balance that
resulted in lower performance resources from attaining overloaded with requests. There are also
cases where the high-performance resources remain idle. Therefore, server load balancers are the
obvious choice for efficiently managing accessibility concerns and stable performance.
Server load balancing is thus the process where the load balancers disseminate service requests all
through the server groups. The process addresses the various requirements that are an important
aspect of the network, such as:
High performance , availability and disaster recovery
Various content-intensive applications can scale beyond a point where a single server can provide
enough processing capacity. However, both the organization and solution providers need elasticity
to implement additional servers quickly and transparently to the end users. Furthermore, server
load balancing allows various servers to appear as a single server, i.e. one virtual service. This can be
done by distributing requests amidst the servers transparently.
Solution providers of SSL VPN services have come up with advanced load balancing solutions that
enable end users to gain a high performance by intelligently using the processing power of the
servers. High-end server load balancers can therefore direct user request to the servers that are less
busy and can provide fast response time. This apart, an efficient load balancer should possess the
capacity to manage the aggregate traffic of multiple servers. If a server load balancing equipment
becomes an obstacle then it’s an additional issue that requires to be sorted out. Simultaneously,
load balancers also have the capacity to improve application availability. When a server or
application fails, then load balancing appliances automatically redistribute the user service requests
to other servers within the server farm.
In addition to that, the process of server load balancing avoids planned outages for hardware or
software maintenance from hindering service to end-users. Distributed server load balancing
solutions provide disaster recovery solutions by redirecting service requests to a backup location
any failure blocks the primary server.
