In general, a load balancer is placed between a client and a host, and its function is that when a host encounters a disruption or fails, the load balancer service detects this problem and quickly directs or routes the requests of clients related to that unavailable host to healthy hosts.
“Load balancing is used to increase network performance and speed, and is generally important for servers where it is difficult to predict the number of requests sent to the server. These include sites with high traffic and university sites that require a large number of users to register at the same time.”
The Least Response Time method is based on the amount of server resources and the low response time.
The Round Robin mechanism works like a queue. For example: first request to the first server, second request to the second server, and so on.
The Least Connection method performs load balancing based on the fewest active connections.
The Custom method is custom and can be used in combination with several of the above methods.
The Least Packets method performs the check based on the smallest amount of packets.
The Least Bandwidth method performs LB based on the maximum bandwidth of the server.
SPF or Single Point Of Failure is used when you do not have redundancy and if that thing fails, your network will suffer. Example: In a network, if you have a router and the router fails and there is no replacement, it is called SPF.
Clustering means clustering. In clustering, the user sees only one IP, while behind this there may be several servers and they LB your request among themselves and deliver the result to you in the form of an IP address. The word Distribute means that we have several specific things and then we distribute something on them. Example: Distributing user requests on LB.
Load balancing is the division of workload between servers. For example, suppose you enter the Google website and use it in any way. Here your request does not go to only one server, but your request is divided between multiple servers. This concept is called load balancing.
As briefly mentioned above, load balancing technology is one of the fundamental factors in information exchange in today’s cyberspace. Unfortunately, this technology is currently unfamiliar to most people and in many cases is not considered a principle in network engineering.
Load balancing initially began its role in the IT world in the form of network-based traffic load balancing hardware and is now a vital component of Application Delivery Controller (ADC) methods.
After the initial use of load balancing in networks, their second significant use as more advanced devices was the network load balancer, which actually played the role of the father of today’s ADC methods. Since these devices were able to operate independently and outside the application server (Application server), they could properly perform the task of load sharing using Straightforward network techniques.
Load balancers incorporate concepts such as the following, although the literal meaning of each of them differs depending on its use in this technology.
