Elastic Load Balance Video

Elastic Load Balance (ELB) automatically distributes incoming traffic across multiple Elastic Cloud Servers (ECSs) to balance their workload, increasing the service capabilities and fault tolerance of your applications.

Robust Performance

ELB offers high cluster scalability to handle a large number of access requests.

High Availability

ELB is deployed in cluster mode and supports real-time seamless switchover 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.

Application Scenarios

  • High Traffic Websites

  • Disaster Recovery

High Traffic Websites

High Traffic Websites

ELB intelligently distributes traffic to ensure smooth running of application services. This makes ELB the right choice for websites with a large number of simultaneous requests.

Advantages

  • Flexible Expansion

    ELB automatically scales according to changes in the incoming traffic.

  • High Performance

    ELB offers high cluster scalability, making it the right choice for scenarios involving a massive number of access requests.

Disaster Recovery

Disaster Recovery

ELB distributes incoming traffic across AZs, facilitating real-time disaster recovery. Enterprises like banks can use ELB to ensure high service availability.

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.

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.

Getting Started

  • Create Certificate

  • Apply for ELB

  • Add Listener

  • Add Backend ECS

Create Certificate

Steps

1. Log in to the ManageOne operation plane and go to the ELB console.

2. On the Certificate tag page, click Create Certificate.

3. Create a certificate.

Note

• Region Type I supports certificate creation is supported only in the scenario.

Apply for ELB

Steps

1. Log in to the ManageOne operation plane and go to the ELB console.

2. In the upper right corner of the page, click Apply for ELB.

3. Apply for a load balancer.

Note

• You can set a virtual IP address for the load balancer or bind an EIP to the load balancer.

Add Listener

Steps

1. Log in to the ManageOne operation plane and go to the ELB console.

2. Select an ELB and click Add Listener on the Listener tab page.

3. Add a Listener.

Note

• Region Type I supports the configuration of a backend ECS group.

• If you select Create new for Backend ECS Group, the backend ECS group and health check can be configured at the same time.

Add Backend ECS

Steps

1. Log in to the ManageOne operation plane and go to the ELB console.

2. (Type I) On the Backend ECS Group tab page, click Add Backend ECS in the Operation column.

3. (Type II) Select an ELB and click Add Backend ECS in the Operation column of the listener.

4. Add backend ECSs.
