Load Balancing - What is Load Balancing?
Load balancing is simply defined as a method of distributing traffic across different servers. Traffic and volume of traffic from users will be distributed in a controlled manner to all servers in the system in a reasonable way, not just stopping at a single server.
The traffic volume will be effectively distributed among the servers to increase the responsiveness of the website system and enterprise applications to the highest level. The load balancing feature can do this because it stands between the user's access devices and the backend servers, receiving the queries to the system and distributing them to the servers currently capable of carrying the load and meeting the requirements of those queries.
Load balancing is divided into 2 modes - 2 completely different ways of operating. Includes Hardware Load Balancing and Software Load Balancing:
- Hardware Load Balancing: Hardware load balancing technology was born in the 90s of the last century. They are computer hardware devices that run on closed-source software, specifically built to run on custom processors. With more and more traffic, the number of load balancers must increase proportionally to be able to meet the service needs of customers.
- Software Load Balancing: A cost-effective solution that delivers optimal operating performance for businesses. We just need to install load balancing software into our system, and still ensure the amount of traffic that the system can bear while not having to spend a huge amount of money on the use and operation of physical load balancers.
Importance of load balancing to enterprise transmission problems
The Load Balancing tool's server management and query navigation is just the tip of the iceberg. Below, let's take a look at the top and most important benefits of load balancing, especially why it's being used by leading enterprises on a global scale.
1. Automate easily
Load Balancing tool in action will allow businesses to identify traffic bottlenecks in advance with its analysis and reporting tools. Load balancing provides detailed information about your systems, websites, and applications almost instantly when you need them, which greatly influences your business decisions. These are the most important foundations for building an effective automation process for business activities.
2. Seamless handling of traffic spikes on the system
When the enterprise's services are operating and the workload is too large, it will lead to single servers being overloaded by sudden traffic spikes. But with the Load Balancing feature, the system will automatically direct traffic to the available and stable servers in the system, thereby ensuring the fastest availability for the service of the business on the cloud platform. Even in times of constant incoming traffic, business processes and operations can continue to run without any disruption.
Beyond load balancing, sudden traffic spikes sometimes come from malicious requests targeting your web application. You can add a filtering layer based on the standard OWASP ruleset, set up in a few minutes and completely free with WAF Free.

3. Scalability and easy development
When there is an unusual spike in traffic on the system that negatively affects the performance of the origin server, Load Balancing can provide additional virtual servers to the system to handle the surging traffic load. That is, when there is a large amount of access to the website and application system of the enterprise, thanks to the load balancer, we can immediately expand the server system to respond to access requests.
With the support of the Load Balancing system, increased traffic will be seamlessly distributed between new servers and web application versions of the system, increasing the load capacity of the entire system and bringing stable operations to the business.
How Load Balancing deals with force majeure situations
In the event of force majeure situations, such as when a geographical area is affected by natural disasters such as earthquakes, floods, etc. that cause concerning impacts on the operation of the server system, the load balancer will immediately direct traffic at that location to servers in the surrounding area (without being affected by the situation) to ensure the availability of services of the operating business.
In addition, when a load balancing system is built using certain load balancing algorithms, the system will be able to identify and predict in advance which particular single servers or groups of servers are likely to get overloaded more quickly than usual when there is a spike in traffic. In this case, the load balancing feature on the system will automatically direct traffic to the server-connected networks in the system that it considers "stronger", built and fully equipped to handle this spike in traffic.
Keeping your website and web application available also means blocking abnormal requests early at the application layer. WAF Free helps you do that without a dedicated security team or complex infrastructure.

VNIS Smart Load Balancing with AI machine learning technology
To be able to operate the system smoothly and maintain the professional service level of your business, it is extremely important to invest in a Load Balancing system. Load balancing is the key to the responsiveness and availability of your system when your customers need you most, ensuring that none of your potential customers leave your website and enterprise application ecosystem with dissatisfaction when services and utilities take too long to respond.
At VNIS (VNETWORK Internet Security), the load balancing feature is built with the application of AI technology - Automatic Machine Learning. There is no transmission service provider on the market that can guarantee 100% uptime and the highest performance on their system. But with VNIS's AI Load Balancing feature, the system is trained by machine learning, and can accurately measure and evaluate the operating performance of the servers in the system. From there, it decides on traffic distribution or availability issues that the system predicts.
On the VNIS Platform, right after users Power-Up by activating the Multi CDN system, AI load balancing will be activated automatically. Our database-driven decision-making system continuously measures the performance of CDNs globally for the most accurate load balancing decisions. Maximize website availability by automatically switching between different CDN systems to ensure optimal system uptime. As soon as force majeure emergencies occur, users can easily direct traffic to a specific area with just a few clicks.
In addition, if you are looking for a companion for your business in security issues and fast information transmission, please contact us. VNETWORK is currently providing comprehensive solutions in the field of information technology for digital businesses:
VNIS - A comprehensive, dedicated website security solution for digital businesses, against DDoS attacks with the largest amount of traffic (global CDN bandwidth up to 2600Tbps).
VNCDN - Solution to accelerate website by CDN (Content Delivery Network) technology with domestic bandwidth up to 3Tbps. Ready to reach up to 3 million concurrent users.
With no large budget required, businesses can start with the WAF Free package within the VNIS ecosystem today — free, easy to integrate, and ready to upgrade to more comprehensive protection packages as traffic scales up.
