Load balancing software will help in network administration as it is used to address the network load management needs. The software is used to route network traffic to the right servers based on configuration; doing so with the help of load balancing software will prevent costly bottlenecks. The load balancing software can be directly installed onto servers or may be purchased as a service, known as a load balancer as a service. The best load balancing software can be deployed on-premises and off-premises easily. This software will evaluate client usage in real-time and their requests then, accordingly, allocate requests to different servers based on different algorithms. The load balancing software market is expected to reach USD 6.5 billion by 2025, at a CAGR of 13.8 % from 2020-2025.
Let us know a little more about load balancing software; there can be different algorithms that it may use for optimizing network traffic and assigning available servers
Round-robin algorithm: this algorithm is the simplest where the request is moved in the same order to available servers.
Least time algorithm: this algorithm may integrate weighted algorithms with preferences to the server with better capacity, higher memory, and power; in this case, servers are selected based on the fastest processing speed and least active requests.
Least-connection algorithm: this algorithm figures out the least busy server and directs the request to the server with the least workload.
Hash-based algorithm: a hash key is assigned to the client and server IP addresses. In this algorithm, the request from users is sent to the same server that contains data from the previous session. It is believed to be an efficient way of working.
Here is how you make your network secure with the help of a balancing software
Using balancing software can add additional layers of security without any changes to the application; it helps in following ways
- Eliminates the risk of emerging threats, and scan viruses and protect from hackers with the help of web application firewall load balancing software.
- Before even distributed denial-of-service can get your way, load balancing software will detect and drop it.
- The software can implement strict authentication policies, wherein the software can request a username and password before granting access to the website.
- Simplifies payment card industry regulations
Load balancing software helps in reducing the load on web servers and optimizes the traffic; it secures the traffic with Secure Socket Layers and removes overhead from web servers leading to increased availability of resources for web applications. The software also has the ability to even compress the traffic for a better user experience; it can also retain a copy of frequently accessed elements so that it can quickly deliver the content to users. The most important feature of the software is that it supports HTTP 2.0 even if the webserver does not support it and results in a much quicker response of websites.
If the webserver fails, the load balancing software will continue to provide service to the remaining servers with no impact on other users, and on being busy, the request is sent to another web server without any issue plus they can be deployed in pairs so that if one server fails, another server can take over and balance the load. With the help of load balancing software, it is easier to change the infrastructure without disrupting other users; one can detect site outages and redirect users to the alternate website.
It is easy to scale up the infrastructure without disruption to other users. One can detect site outages and will redirect users to the alternate site with the help of load balancing software. The software enables to add of more websites by just deploying additional servers, and it will be available to other users easily.
Unlike hardware, software load balancers can easily be deployed on-demand and can save money as well.
