Features & Benefits of Load Balancers
Load balancing offers high accessibility and scalability to enterprise-wide TCP/IP services, for instance terminal services, web, proxy, virtual private networking and streaming media services. Load balancing servers also known as hosts in a cluster communicate within themselves to offer a set of benefits such as:
Scalability – Server load balancing scales the performance of a server based program, for instance a web server, by disseminating its client requests all through various servers within the cluster.
High availability – Server load balancing offers high availability by detecting server failure automatically and repartitioning client traffic all through the remaining servers within as less as ten seconds, while offering users within ongoing service.
The way load balancers work
Load balancers scales the performance of a server based program, for instance a web server. With load balancing every incoming IP packet is received by every host, but accepted by the intended recipient. The cluster hosts simultaneously respond to multiple client request and even various requests from one client. For instance, a web browser may attain multiple images within a web page from various hosts in a load balancer cluster. This speeds up the processing and lessens the response time to clients.
Today service providers specializing in application delivery controllers have come up with advanced load balancers that efficiently leverage the multi-core processing to cost-efficiently drive excellent performance all through a rich server load balancing and application feature that offers unparalleled value of ownership. Load balancers boost application performance and accelerate the ROI. Other services and benefits include the following:
Offers local and global server load balancing with multi-unit clustering for 99.999% application uptime and data center scalability
Innovative application-fluent traffic management for optimized delivery of business critical applications and IP services
Provides offloading of Web and application servers for maximized efficiency, capacity and return on investment
Offers SSL acceleration for safeguarding data in transit, offloading compute-intensive processes from servers and improving application performance
Provides a reverse-proxy architecture with a packet-inspection firewall for guarding applications without impacting performance
There is application-specific certifications and configuration guides for rapid deployment of optimized configurations
Server load balancing can be installed automatically and enabled optionally on a server and datacenter server versions of the Windows 2000 operating system. It functions as a functional service for local area network connections and is enabled for a LAN connection in the system. There are no hardware charges to implement and operate server load balancing. It is also compatible with all Fiber Distributed Data Interface (FDDI) and Ethernet network adapters and hence no certain hardware compatibility criteria.
