On a daily basis, we use countless websites and applications at the same time as millions of other people on Earth. While we each access these platforms, or local area networks (LAN), from our own personal devices, the connections for each platform come from the same server or set of servers. If a platform has dozens of users at a time, it may use a single server to represent the data to the users; however, if a platform has hundreds or thousands of users at one time, it will require multiple servers. In turn, these servers must be balanced, and this need is met by the installation of a load balancer. Load balancing works as a ‘reverse-proxy’ to represent the application servers to the client through a virtual IP address (VIP). This technology is known as server load balancing (SLB). In order to increase both availability and scalability, a load balancer uses specific algorithms to steer traffic to the available servers, monitor for when additional servers are needed, and identify when servers are not required. This blog will cover the basics of what you need to know about the different types of load balancing for your applications.

Antennas are integral parts of wireless local area networks (WLANs). They generate and maintain the wireless signal we utilize to browse the web, stream movies, work from home, and more.
