Understanding load balancers
In the fast-paced world of modern computing, organizations face ever-increasing demands for high availability, scalability, and optimal performance of their online services and applications. Network load balancers are an integral component of modern network infrastructure, playing a crucial role in managing the distribution of network and application traffic across multiple servers. It’s a solution designed to ensure efficient resource utilization and prevent any single server from being overwhelmed and being a single point of failure:

Load balancers provide the following benefits:
- Increased scalability: They enhance the capacity and reliability of applications by ensuring no single server becomes a bottleneck
- Improved performance: They reduce response time by efficiently managing traffic and ensuring that no single server is overburdened
- High availability...
