Using advanced forwarding for application iteration

As the business grows, you may need to upgrade your application based on the users' feedback. Both the old and new versions are used. After the new version is ready, all the users are directed to the new version. In this process, you can use advanced forwarding to route requests to different versions.

Routing traffic across cloud servers and on-premises servers

You can enable IP as a Backend when creating a dedicated load balancer and associate on-premises servers with this load balancer by using their IP addresses.

2

Transfer client IP address

Generally, shared load balancers use IP addresses in 100.125.0.0/16 to communicate with backend servers. If you want a load balancer to communicate with backend servers using the real IP addresses of the clients, you can enable Transfer Client IP Address.

Security policy

ELB supports three more security policies, including TLS-1-0-WITH-1-3, TLS-1-2-FS-WITH-1-3, and TLS-1-2-FS.

Supported TLS protocol versions:

• TLS-1-0-WITH-1-3: TLS 1.3, TLS 1.2, TLS 1.1, and TLS 1.0
• TLS-1-2-FS-WITH-1-3: TLS 1.3 and TLS 1.2
• TLS-1-2-FS: TLS 1.3 and TLS 1.2

Hybrid load balancing

For dedicated load balancers, you can associate servers in a peer VPC, in a VPC connected through a cloud connection, or in an on-premises data center at the other end of a Direct Connect or VPN connection, by using the server IP addresses. In this way, incoming traffic can be flexibly distributed to cloud servers and on-premises servers for hybrid load balancing.

Dedicated load balancer

ELB has launched dedicated load balancers that feature exclusive resources and guaranteed performance. Enhanced load balancers are renamed shared load balancers. ELB now provides the following types of load balancers.

3

HTTPS support

You can select HTTPS for both your listener and the associated backend server group to verify the validity of requests on your load balancer and backend servers and improve service security. This allows you to enable mutual authentication on the load balancer and backend servers.

4

Slow start

You can enable slow start for HTTP and HTTPS listeners. After it is enabled, the load balancer linearly increases the proportion of requests to backend servers in this mode. When the slow start duration elapses, the load balancer sends full share of requests to backend servers and exits the slow start mode. Slow start ensures that applications start smoothly and can respond to requests with optimal performance.

IPv4/IPv6 dual stack

Dedicated load balancers can work in both private and public networks and support IPv4/IPv6 dual stack.

QUIC

If you add a UDP listener to a dedicated load balancer, you can select QUIC for the associated backend server group and use the connection ID algorithm to route requests with the same connection ID to the same backend server.
