Load balancing software divides user traffic across servers to prevent strain and maintain optimal network performance. When a user requests access to a resource, load balancing software assigns the request to a server based on static and dynamic algorithms. The purpose of this process is to evenly distribute incoming network traffic to ensure a high level of availability and application performance.

Load balancing software can be deployed in various ways, including as hardware software solutions, and cloud-based services, all designed with the goal of evenly distributing the network load to prevent overload, optimize resource usage, and minimize latency. Modern load balancing solutions cater to different types of applications, architectures, and network protocols while providing features like SSL/TLS offloading, session persistence, health monitoring, and analytics.

In this article, we will cover our list of the top load balancing software based on their features, performance, scalability, ease of deployment, and overall customer satisfaction.

AWS Elastic Load Balancing (ELB) distributes network traffic across multiple targets, ensuring improved application scalability and high availability. ELB supports various environments, such as Amazon EC2 instances, containers, IP addresses, microservices, Lambda functions, and appliances in single or multiple Availability Zones (AZs).

There are three types of load balancers to choose from based on specific application needs – Application Load Balancer for flexible application management, Network Load Balancer for extreme performance and static IP, and Classic Load Balancer for applications built within the EC2-Classic network. ELB offers enhanced security through Amazon Virtual Private Cloud (VPC) and its associated security groups, allowing configuration for internet-facing or internal load balancers.

Elastic Load Balancing efficiently scales its request handling capacity in response to incoming traffic and can handle sudden surges in demand. ELB also conducts health checks on targets to make sure they are available, ensuring traffic is only routed to healthy instances. Other notable features include sticky sessions for routing requests from the same client to the same target, operational monitoring through Amazon CloudWatch metrics and AWS CloudTrail API call tracking, as well as delete protection to prevent accidental load balancer deletion.
