Load balancing can optimize response time and avoid unevenly overloading some compute nodes while other compute nodes are left idle. Load balancing is the subject of research in the field of parallel computers. Two main approaches exist: static algorithms, which do not take into account the state of the different machines, and dynamic ...
Kemp, Inc. is an American technology company that was founded in 2000 in Bethpage, New York. [2] The company builds load balancing products which balances user traffic between multiple application servers in a physical, virtual or cloud environment.
To accomplish this, an ADC includes many OSI layer 3-7 services, including load-balancing. ADCs are intended to be deployed within the DMZ of a computer server cluster hosting web applications and/or services. In this sense, an ADC can be envisioned as a drop-in load balancer replacement. But that is where the similarities end.
Pound is a lightweight open source reverse proxy program and application firewall suitable to be used as a web server load balancing solution. Originally developed by an IT security company, it has a strong emphasis on security.
Incapsula also has a content delivery network that caches websites on their server network to speed up website load time. The cached information is returned from a server closest to the end user to provide fast page loads. This also allegedly militates against slow responses due to heavy server traffic. [14]
Round-robin DNS is a technique of load distribution, load balancing, or fault-tolerance provisioning multiple, redundant Internet Protocol service hosts, e.g., Web server, FTP servers, by managing the Domain Name System's (DNS) responses to address requests from client computers according to an appropriate statistical model.
Network Load Balancing Services (NLBS) is a Microsoft implementation of clustering and load balancing that is intended to provide high availability and high reliability, as well as high scalability. NLBS is intended for applications with relatively small data sets that rarely change (one example would be web pages), and do not have long-running ...
Server-load balancing uses one or more techniques including service-based (global load balancing) or hardware-based (i.e. layer 4–7 switches, also known as a web switch, content switch, or multilayer switch) to share traffic among a number of servers or web caches.
