6 Key Reasons for Using a Software-based Load Balancing Software

Everybody loves apps that run on request. Not only are applications that are offline or late to react annoying, but they also pose a major danger to customer loyalty, brand awareness, distinction, competitiveness, and sales. The load balancer is an important network tool that allows for device quality and availability. For application compatibility, efficiency, and data security, load balancing software smartly manages network traffic between numerous registered databases. It is possible to divide load balancers into two categories: software and hardware. This blog offers six main reasons why businesses should accept software-driven load balancers to manage incoming traffic and provide business-critical services with availability, reliability, and transparency.

Considerable benefits are offered by software-driven load balancers. They aren’t just easier to procure, supply, and install, but are often customizable, modular, efficient, and much less expensive. Based on the IP addresses of the optimal database, client, and server positions, server accessibility and tunable routing algorithms (e.g., Round Robin, Weighted Round Robin, topography, global, etc.), they can effectively disperse incoming traffic. They also support a variety of configurable application and network health checks, SSL termination, aggregate throughput, and more. Let’s take a quick look at the benefits given by software-defined load balancers.

Quick Acquisition & On-Demand Implementation

A major benefit of software-defined load balancers is that they can be installed and implemented on demand. In comparison, hardware-based load balancers must be selected, purchased, and then physically shipped, assembled, calibrated, implemented, and eventually managed, usually after a waiting period. However, software-based systems only need a dedicated registry and a license key for installation before implementation. Instant implementation is a preferable option when speed, performance, and lower costs are critical. It can be deployed in on-premises or cloud systems and can be distributed to Intranet apps internally and Internet applications externally. It could also be used where datacenters and servers are geographically dispersed for Global Server Load Balancing (GSLB).

Scalability for Optimized Utilization

Scalability refers to the ability to handle high traffic levels and enhanced network & processor demand in actual environments without quality harm. Software-defined load balancers level up in real time to ensure scalability. Hardware-based best load Balancing software, on the other hand, have intrinsic physical constraints that make it harder to scale beyond equipment thresholds. By comparison, software load balancers can channel thousands and thousands of concurrent requests and can accommodate an unexpected amount of traffic since they use server power instead of specialized hardware. When traffic increases, dynamic automated-scaling adds and records servers and retracts when traffic declines. This prevents over-subscribing or under-utilizing of servers.

Designed for Quick Response

Programmability makes software load balancers significantly more beneficial. Health checks may be specified for a shared system of databases, for different clusters of different servers, or for containers. This can also be achieved at the device and network stages. To verify the health of goal endpoints, status check codes may be programmed. In order to prevent bottlenecks or over-subscribed cases, a number of health tests, including HTTP/S, SNMP, TCP, SIP, PDP, and ICMP, may be established. To automatically create structured business processes based on health tests, measurements for tracking systems and servers can be used. To save time, decrease errors, increase capacity, and monitor load balancer frameworks, automation can be introduced through scripts. In addition, for greater precision, expandable characteristics may be specified to provide administrators with the required visibility across the network.

Security for Data Protection and Malware Mitigation

Positioned between the server and the client, load balancers provide the enterprise with an additional layer of software protection. The SSL communication may be broken at the load balancer or at the recommended intervals, using SSL/TLS communication protocols. This prevents message alteration when the packages are in transit. Domain controllers or a virtual firewall can create inbound laws and regulations, while the program can be mounted up in private nodes. Only input from the load balancers would be permitted by inbound/outbound rules and regulations linked to the application servers. In addition, in the mutual accountability model, cloud vendors take accountability for the balancers’ external protection and also ensure that they follow varying levels of conformity.

Centralized Management for Visibility, Control, and Efficiency

By managing global server load balancing (GSLB) and DNS from a single domain controller, a consolidated UI for the whole organization with no need for a different device simplifies compliance, quickens rollout, increases operating performance, and reduces costs. Joint effort between IPAM and GSLB facilitates request responsiveness by linking client and server positions, usability of servers, internet user location GeoIP data, and policy settings from one central framework for load balancing judgments. Advanced reporting, request logging, and predictive analytics with prebuilt, out-of-the-box, and customized reports, offers the requisite network insight to access data when and where it is most required. Finally, it helps to forecast the future; using modeling to determine when future needs might not be fulfilled by DNS / DHCP capabilities.

Lower Cost

Last, and definitely not least, one of the most persuasive advantages of load balancers is their significantly lower price. Cloud provisioning of load balancers helps users to set up as many load balancers as they want but pay even less. Unlike their hardware counterparts, which are significantly more costly to procure, update, deploy, and manage, provisioning for software-defined load balancing software is achieved easily via a single interactive console or CLI.


In order to ensure continuous availability, performance, and visibility of business-critical applications, load balancers are important in distributing traffic to ideal servers. Hardware and software load balancers can achieve these tasks using different routing algorithms and health tests. There are, however, a range of persuasive reasons for businesses to choose a load balancer identified by software. Quick procurement and on-demand implementation, scalability for optimized usage, programmability for rapid response, stability, unified visibility management, monitoring and performance, and lower total costs are the most common benefits. Together, they create a persuasive case for the use of a load balancer powered by software.
