Solving the Bottleneck Challenge in Distributed Systems with Load Balancing
In today’s digital era, the demand for high-performance distributed systems is ever-growing. However, as systems scale, they often encounter bottlenecks that hinder their ability to handle increasing loads efficiently. One common bottleneck arises from uneven distribution of workload across system components, leading to resource exhaustion, degraded performance, and even system failures. In this blog post, we'll explore a scenario of a distributed system encountering such a bottleneck and propose a solution using load balancing techniques.?
Understanding the Bottleneck
We are managing a cloud-based application that experienced sudden spikes in user traffic during peak hours. Our application comprises multiple servers that handle incoming requests. However, due to uneven distribution of requests, some servers are overloaded while others remain underutilized. This resulted in degraded performance for users and increased the risk of server failures.?
Identifying the Solution: Load Balancing
We worked on the problem and identified that load balancing is a technique used to distribute incoming network traffic across multiple servers, ensuring optimal resource utilization, improved responsiveness, and high availability. By evenly distributing the workload, load balancers mitigated bottlenecks and enhanced system scalability and reliability.?
Implementing Load Balancing
There are popular open source load balancers renowned for high performance, reliability, and advanced load balancing capabilities.
Let's delve into how we can leverage these to address the bottleneck in the distributed system.

Step 2: Configuration?
In this configuration requests are forwarded to the backend servers in a round-robin fashion.?
Step 3: Restart
After making changes to the configuration file, restart to apply the changes.?
Conclusion
In this blog post, we explored a scenario of a distributed system facing a bottleneck due to uneven workload distribution. By implementing load balancing technique, we can effectively address the bottleneck, ensuring optimal resource utilization and enhanced system performance. Load balancing is a powerful technique for improving scalability, reliability, and responsiveness in distributed systems, making it a cornerstone of modern infrastructure architecture.
