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 area 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.
Progent is experienced with a wide range of load balancing technologies covering server balancing, application balancing, and LAN/WAN infrastructure routing. Progent offers consulting expertise with products from the leading vendors of load balancing technology including Microsoft, Cisco, Citrix, and F-5 networks.
Windows Server 2016 Virtual Machine Load Balancing
VM Load Balancing is a new feature of Windows Server 2016 that can automatically and non-disruptively migrate virtual machines between nodes within a Failover Cluster. VM Load Balancing improves Failover Cluster availability and performance and can help you avoid the need to add physical servers to peak workloads. Virtual Machine M Load Balancing automatically determines whether a node has become over utilized and moves virtual machines from the over-committed node to an under-committed node, for example a server that has been freshly rebooted. This entails no cluster downtime, adheres to failure policies such as fault domains, and uses advanced heuristics for measuring VM memory pressure and CPU utilization of the node. Virtual Machine Load Balancing can be set up to run every 30 minutes or on demand. You can use PowerShell to pick one of three thresholds for establishing the aggressiveness of load balancing.
VM Load Balancing automatically performs live migration of virtual machines from over-utilized to under-utilized nodes
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. Progent'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.
