Usually, load balancers are implemented in high-availability pairs which may also replicate session persistence data if required by the specific application. [13] Certain applications are programmed with immunity to this problem, by offsetting the load balancing point over differential sharing platforms beyond the defined network.
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.
HAProxy is a free and open source software that provides a high availability load balancer and Proxy (forward proxy, [2] reverse proxy) for TCP and HTTP-based applications that spreads requests across multiple servers. [3] It is written in C [4] and has a reputation for being fast and efficient (in terms of processor and memory usage). [5]
Perlbal is a Perl-based reverse proxy load balancer and web server. [2] Perlbal is maintained by a group connected to Danga Interactive.The program is in common use by large web sites to distribute the load over a number of servers.
Nginx can be deployed to also serve dynamic content on the network using FastCGI, SCGI handlers for scripts, WSGI application servers or Phusion Passenger modules, and can serve as a software load balancer. [21] [20] Nginx uses an asynchronous event-driven approach, rather than threads, to handle requests. [22]
Network load balancing is the ability to balance traffic across two or more WAN links without using complex routing protocols like BGP.. This capability balances network sessions like Web, email, etc. over multiple connections in order to spread out the amount of bandwidth used by each LAN user, thus increasing the total amount of bandwidth available.
An application delivery controller (ADC) is a computer network device in a datacenter, often part of an application delivery network (ADN), that helps perform common tasks, such as those done by web accelerators to remove load from the web servers themselves. Many also provide load balancing.
For a typical web application, the application server sits behind the web servers. An application server framework is a service layer model. It includes software components available to a software developer through an application programming interface. An application server may have features such as clustering, fail-over, and load-balancing.
