Can Load balancing help against DDoS attacks?

The Load balancing is a critical component for preventing DDoS attacks. Why? We will take a detailed look at that a bit later in this article. Let’s start.

What does Load balancing mean?

Load balancing in DNS is a way of dispersing client requests among server machines using domain configuration. The domain can be linked to a website, email system, or any other Internet-based service.

If you operate a large and popular website, you may expect a lot of requests for it. It must also be speedy, give up-to-date information, and accurately and rapidly handle the requests it receives. This is where the concept of traffic balancing comes into play.

How does it work?

To better understand how DNS Load balancing works, it’s best to go through the steps in the following order:

  1. Your website receives traffic. The Internet sends a large number of requests from users and clients to your website’s server.
  2. The traffic is spread out over the server’s resources. Each request gets routed to the proper server via the load balancer.
  3. Each server is given a manageable burden. When the server receives the request, it decides whether or not to accept it. It then responds to the balancer with an answer if it is not overburdened with requests.
  4. Server answers to the query. Finally, the process repeats but in reverse order to return the server’s response to the user.

DDoS attack – definition

DDoS (Distributed Denial of Service) attacks are attempts that take advantage of network resources’ specific capacity restrictions. As a result, it disrupts critical objectives like a network, system, or server. The DDoS assault floods the targeted online site with requests. The goal is to exceed the website’s capacity in order to serve a higher volume of queries. Finally, to prevent the website from functioning properly.

Load balancing – a prevention of DDoS attacks

Load balancing is a good security strategy for protecting against DDoS attacks. We discuss above its primary purpose. To distribute workloads over numerous servers in order to avoid overloading them, improve productivity, and increase uptime. In addition, Load balancing enhances robustness by rerouting live traffic from one server to another in the event that one becomes unavailable due to DDoS attacks or other factors. Load balancers help to limit the attack surface, eliminate single points of failure, and make it more difficult to exhaust resources and saturate networks in this way.

Using several DNS servers to route data could help prevent DDoS attacks and be helpful in everyday settings. For example, consider the following scenario: you’re running a sale on your website, and you’re aware that a traffic spike at a specific period is conceivable. If you don’t hire additional labor, your website may fail, resulting in a slew of angry customers. This could potentially be detrimental to your brand.


Taking everything into account, Load balancing could be absolutely handy as a defense against DDoS attacks. Why? Because it redistributes the load, and in the event of a DDoS attack, your site will not be down and will continue to function normally.
