Generally speaking, Load Balancers spread work between two or more computers, network links, CPUs, hard drives, or other resources, in order to get optimal resource utilisation, throughput, or response time. Using multiple components with load balancing, instead of a single component, may increase reliability through redundancy. The balancing service is usually provided by a dedicated program or hardware device.
Load balancing is most commonly used to mediate internal communications in computer clusters, especially high-availability clusters.
Through our partnership with Riverbed Technologies and now Brocade, IP Performance offer a variety of software and hardware appliance-based server load balancing solutions, including the award-winning Virtual Traffic Manager (VTM). Brocade VTM adds load balancing and resilience to your web services, with high-performance SSL and content compression, content-aware traffic management rules and flexible health monitoring. It offers a low-cost starting point, with a smooth and cost-effective upgrade path to scale as your service grows.
Brocade VTM is available as software, as a hardware appliance and as a Virtual Appliance (for VMware Virtual Infrastructure 3 and Windows Server 2005 R2).
