Robust Performance
ELB can simultaneously process hundred millions of 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 Auto Scaling (AS) to flexibly expand the service capabilities of your applications.
Easy to Use
ELB can be quickly deployed, and diverse protocols and algorithms are available, enabling you to easily configure load distribution policies for different scenarios.

Advantages
-
Flexible Expansion
ELB automatically scales its request handling capacity according to the incoming traffic.
-
Uninterrupted Service
ELB distributes traffic across AZs, ensuring service continuity even if an AZ becomes faulty.
Flash Sales
ELB works with AS to add more ECSs and balance the workload during promotion periods.
Advantages
-
Elastic Scaling
ECSs are automatically added or removed according to changes in the service traffic.
-
High Availability
ECS health status is regularly monitored and traffic is distributed only to healthy ECSs, ensuring service continuity.
-
High Performance
ELB automatically scales to hundred millions of concurrent connections, making it the right choice for handling a large number of access requests.
New Features
Functions
Multiple Protocols
Multiple protocols are supported at layer 4 and layer 7, facilitating diverse application scenarios.
-
Layer 4 load balancing
TCP and UDP are 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 are used at layer 7, and multiple encryption protocols and cipher suites are available for HTTPS to ensure service flexibility and security.
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.
-
Cross-AZ load balancing
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.
