Elastic Load Balance (ELB)
Elastic Load Balance (ELB) is a service that automatically distributes incoming traffic across multiple Elastic Cloud Servers (ECSs) to balance their service load. It enables you to increase service capabilities and fault tolerance of your applications.

Traditional Hardware Load Balancer
ELB: Features a redundancy design to automatically remove abnormal nodes and route traffic between normal nodes to ensure service availability.
Traditional Hardware Load Balancer: Service restoration is slow in case of an exception.
ELB: Automatically expands the processing capability based on the traffic on applications and seamlessly integrates with the Auto Scaling (AS) service to meet the requirements posed by traffic changes.
Traditional Hardware Load Balancer: Changes in traffic demands cannot be handled quickly. If hardware devices have reached their bottleneck, you need to purchase and deploy hardware devices with higher performance. The installation is difficult and the cost is high.
ELB: Supports concurrent processing of a maximum of 100,000 requests to meet users' requirements for heavy traffic, and layer-4 (TCP) and layer-7 (HTTP or HTTPS) load balancing as well.
Traditional Hardware Load Balancer: The service capability is limited and cannot meet a burst of concurrent service requests.
Automatically expands load balancing capabilities based on users' traffic.
Checks the status of backend ECSs, removes an unhealthy ECS from the traffic forwarding list, and resumes forwarding traffic to it after it recovers.
Distributes sessions of a user to a specific backend ECS.
Layer-4 and Layer-7 Load Distribution
Supports load distribution using the layer-4 protocol (TCP) or layer-7 protocol (HTTP or HTTPS).
Works with the AS service to ensure service flexibility and availability.
You can send HTTP/HTTPS requests for calling HUAWEI CLOUD APIs to manage your ECSs. In this way, you can flexibly, accurately, and promptly perform operations on your applications, resources, and data.
