Robust Performance

ELB can simultaneously process up to 100 million connections.

High Availability

ELB is deployed in cluster mode and supports active-active disaster recovery across AZs.

High Scalability

Incoming traffic is intelligently distributed to ECSs. ELB can work with AS to flexibly expand the service capabilities of your applications.

Easy to Use

ELB can be quickly deployed, and load distribution policies can be easily configured for different scenarios.

Functions

Multiple Protocols

Multiple protocols are supported at layer 4 and layer 7, facilitating diverse application scenarios.

  • Layer 4 Load Balancing

    TCP is used to handle services that require high performance and simultaneous processing of a large number of access requests.

  • Layer 7 Load Balancing

    HTTP and HTTPS ensure service flexibility, security, and reliability.

High Availability

A variety of policies ensure high service availability and quality.

  • Health Check

    ECS health status is regularly monitored and traffic is distributed only to healthy ECSs, ensuring service continuity.

  • Intra-City Active-Active Disaster Recovery

    ELB can be deployed across AZs and ensures service continuity even if any AZ fails in the event of a disaster.

Sticky Sessions

Requests from the same client are forwarded to the same ECS within a certain time period to ensure continuous access.

  • Layer 4

    Load balancing at layer 4 maintains sessions using source IP addresses.

  • Layer 7

    Load balancing at layer 7 maintains sessions using cookies.

Elastic Scaling

ELB automatically scales its request handling capacity and works with AS to add or remove ECSs to improve service flexibility and reliability.

  • Seamless Interconnection

    ELB interworks with AS to adjust the number of ECSs according to changes in the service traffic.

  • Automatic Expansion

    ELB automatically scales to the incoming traffic to ensure user experience.
