Elastic Load Balance (ELB)

Deployed in clusters: Redundant design and cluster deployment make traffic distribution across AZs and disaster recovery possible.

Health check: ELB automatically routes traffic to healthy servers. It works with Auto Scaling to add more servers to ensure service continuity or remove servers to avoid resource waste.

Ensured security: You can check the status of your load balancers by viewing metrics on Cloud Eye and various alarm rules you can configure. You can also use Anti-DDoS Service (AAD) to make sure your bandwidth never gets used up by a DDoS attack.

Massive concurrent connections: ELB can handle up to hundreds of millions of concurrent connections.

Seamless integration: You can combine other cloud services with ELB to meet different service requirements.

High scalability: ELB works with Auto Scaling to flexibly adjust the number of servers as traffic changes. Without resource bottlenecks, you can stay better focused on your services.

Service deployed in seconds: You can deploy and roll out services in seconds without need to spend your valuable time planning and cabling.

On-demand service: You pay as you go and just pay for what you use. Once your payment method is configured, you are good to go.

No fixed asset investment: You do not need to invest in equipment rooms, power supplies, construction, and hardware.

Seamless system upgrade: ELB can route traffic uninterruptedly when you launch new services or upgrade your services.

Smooth performance improvement: When you need to expand resources to meet service requirements, there are no hardware upgrades to deal with.
