Benefits of Innovative Load Balancing Appliances
Whilst discussing on the features and advantages of load balancing appliances it is essential to have a clear understanding about the phenomena itself and the way it is applicable to web security. In simple terms, load balancing is the method of evenly distributing work amidst numerous computers. The process has few benefits such as:-
* Reducing the load on individual systems
* Brings down the response time
* Increases network utilization
* Improved reliability
* Enables scaling
* Improves user satisfaction
Load balancing means a systematic practice of routing outgoing and incoming HTTP traffic to either of the numerous servers for monitoring access to websites. It also entails scanning traffic for malware, spyware, phishing and other unimportant content. Furthermore, load balancing addresses few other concerns such as:-
* Enabling the more seat addition i.e. horizontal scalability
* Balances the load of one or more local servers i.e. Server Load Balancing or SLB
* Balances the load across globally-distributed servers i.e. Global Server Load Balancing or GSLB
* Balances across multiple security devices i.e. Firewall Load Balancing
* Fault tolerance
* High accessibility
Leading service providers in application delivery solutions have introduced new age load balancers that enables users to leverage parallel multi-core processing to be able to cost-effectively generate industry leading functionality upon a rich application acceleration and load balancing feature suite for unparallel overall ownership value. Selected advantages of these load balancing appliances are as follows:-
* There are global and local server load balancing along with multi-unit clustering for 99.999% application uptime as well as data center scalability
* There is advanced application traffic management for optimized delivery of business crucial applications and other IP services
* There is offloading of application and Web servers for high efficiency, capacity as well as return on investment
* There is integrated TCP connection multiplexing, high-speed HTTP processing, compression and caching for a 5X improvement in application functionality
* SSL acceleration for safeguarding data in transit, offloading compute-intensive processes from servers and enhancing application performance
* There are reverse-proxy infrastructure with an advanced packet-inspection firewall for securing applications without influencing the performance
* There are application-specific criteria and configuration guidelines for quick implementation of optimized configurations
* Advanced performance of 2048-bit SSL encryption for aligning with NIST and certificate authority security needs
* Extensible XML-RPC for incorporation along with proprietary and other third party data center management and monitoring products
Such high end load balancing appliances improves the application performance and accelerates the return-on-investment for both the small and large scale enterprises.
