Elastic load balancing

What is Elastic Load Balancing

Elastic Load Balancing (ELB) is a powerful cloud-based service provided by Amazon Web Services (AWS) that automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, and IP addresses. At Startup House, we leverage the capabilities of Elastic Load Balancing to ensure high availability, fault tolerance, and scalability for our clients' software applications.

ELB acts as a virtual load balancer, seamlessly distributing the incoming traffic to multiple resources in a way that optimizes performance and minimizes downtime. By evenly distributing the workload across multiple instances, ELB helps prevent any single resource from becoming overwhelmed, thus enhancing the overall performance and reliability of the application.

There are three main types of Elastic Load Balancers offered by AWS:

• Application Load Balancer (ALB): This type of load balancer operates at the application layer (Layer 7) of the OSI model, allowing it to intelligently route traffic based on content and application-specific details. ALB is an ideal choice for applications that require advanced routing capabilities, such as those based on HTTP and HTTPS protocols.


• Network Load Balancer (NLB): NLB operates at the transport layer (Layer 4) and is designed to handle high-throughput, low-latency traffic. It is well-suited for applications that require extreme performance, such as gaming or real-time streaming.


• Classic Load Balancer (CLB): CLB is the original load balancer offered by AWS, providing basic load balancing across multiple instances. While it lacks some of the advanced features of ALB and NLB, it remains a reliable choice for many applications.

Startup House understands the importance of load balancing in modern software development. By utilizing Elastic Load Balancing, we can ensure that our clients' applications are highly available, fault-tolerant, and scalable. ELB automatically scales the load balancer as traffic to the application fluctuates, dynamically adjusting capacity to meet demand and maintaining a consistent user experience.

In addition to distributing traffic, Elastic Load Balancing also performs health checks on the registered resources, ensuring that only healthy instances receive traffic. If an instance fails or becomes unhealthy, ELB automatically reroutes traffic to the remaining healthy instances, effectively isolating any potential issues and minimizing downtime.

Furthermore, ELB integrates seamlessly with other AWS services, such as Auto Scaling, which allows for automatic scaling of the underlying resources based on predefined conditions. This ensures that the application can handle sudden spikes in traffic without compromising performance or availability.

In conclusion, Elastic Load Balancing is a critical component of modern software development, enabling high availability, fault tolerance, and scalability. By leveraging the power of ELB at Startup House, we can deliver robust and reliable applications that meet the demands of our clients and their users.
