Elastic Load Balance (ELB)

Elastic Load Balance (ELB) automatically distributes incoming traffic across servers to balance their workloads, increasing the service capabilities and fault tolerance of your applications.

Robust Performance

With a dedicated load balancer, you get exclusive access to load balancer resources. One dedicated load balancer can easily handle up to hundreds of millions of concurrent connections.

High Availability

You can deploy a load balancer in multiple AZs, so even if one of them goes down, the load balancer in another AZ can take over and continue to route traffic.

Flexible Scalability

ELB makes sure that your applications always have enough capacity for different workloads. It works with Auto Scaling to flexibly adjust the number of servers deployed and intelligently distribute incoming traffic across them.

Low Cost

Take advantage of multiple billing modes to make sure you only pay for what you use or enjoy discounts on long-term subscriptions.

Why Huawei Cloud ELB?

99.95% Service Availability

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.

High Performance and Flexibility

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.

Low Cost, Easy Upgrade, and One-stop Scalability

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.
