In situations where a single server or cluster can’t provide the throughput required for a critical application, load balancing of multiple servers offers a solution that not only enhances performance but, as a natural byproduct, provides fault tolerance by working around failed servers in a load-balanced farm. Firewalls and routers can also be set up in a load-balanced and fault-tolerant configuration so that failures of a single device have limited impact on overall system functionality. It is far easier for users and organizations to manage the impacts of reduced resources or bandwidth than to deal with complete outages.
Load balancing solutions are well suited for many web based applications where the front-end web servers can utilize the services of a back-end clustered SQL Server data repository. Applications such as web-based eCommerce are ideal candidates for a load-balanced configuration. Load balancing can provide greatly improved operational reliability because failed servers are transparently removed from the resource farm, thus making such failures nearly invisible to users.
Once you have established a base architecture for a load balancing environment, you have cleared the way for future growth and scalability because adding additional resources to the server farm is a seamless process.
LG Networks’ is experienced with a wide range of load balancing technologies covering server balancing, application balancing, and LAN/WAN infrastructure routing. LG Networks’ offers consulting expertise with products from the leading vendors of load balancing technology including Microsoft, Cisco, Citrix, and F-5 networks.
Microsoft Windows Server 2003 Network Load Balancing Manager
Microsoft Network Load Balancing (NLB) Manager allows you to create and manage Network Load Balancing clusters from a single computer, and you can also replicate the cluster configuration to other hosts. Microsoft Network Load Balancing Manager makes it easy to create new clusters, add hosts to an existing cluster, configure all host and cluster properties, replicate the cluster configuration to other hosts, and diagnose problems with existing Network Load Balancing clusters. Adding hosts to an existing cluster automatically enables Network Load Balancing on that host and configures cluster parameters on that host. Removing hosts from a cluster automatically disables Network Load Balancing on that host. LG Networks’ Microsoft-certified engineers can show you how to configure and operate Microsoft Network Load Balancing Manager to enhance network performance and simplify system management.
Microsoft Windows Server 2008 Network Load Balancing Manager
Network Load Balancing (NLB) is improved in Windows Server 2008 by the inclusion of support for Internet Protocol version 6 (IPv6) and Network Driver Interface Specification (NDIS) 6.0, Windows Management Instrumentation (WMI) enhancements, and improved functionality with Microsoft Internet Security and Acceleration Server (ISA Server). ISA Server can configure multiple dedicated IP addresses per each NLB node for environments with both IPv4 and IPv6 traffic. ISA Server can also provide NLB with SYN attack and timer starvation notifications during scenarios when a computer is overloaded or is being infected by an Internet virus. Windows Server 2008 R2 includes additional improvements to load balancing clusters with an IP Stickiness feature for providing persistent connections for applications such as shopping carts and a Network Load Balancing Management Pack that allows you to monitor the applications and services running in load balancing clusters.

Cisco Content Services Switches and Cisco IOS-based Routers
Through content fast switching and forwarding, the Cisco CSS 11500 Series switches improve utilization, responsiveness, availability, scalability, and security of Web sites, server farms, cache clusters, and firewall systems. Load balancing is a standard functionality of the Cisco IOS router software, and is available across all router platforms. It is based on standard routing protocols, such as Routing Information Protocol (RIP), RIPv2, Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), and Interior Gateway Routing Protocol (IGRP), or derived from statically configured routes and packet forwarding mechanisms. LG Networks’’s Cisco-certified network engineers can help you select and deploy a Cisco-based network infrastructure that makes good business sense for your environment and can configure Cisco’s IOS Server Load Balancing (SLB) service.
