Pay-as-you-go standard GA instances support multiple endpoint groups for Layer 7 (HTTP/HTTPS) listeners

Update

Pay-as-you-go standard GA instances now allow you to configure multiple default endpoint groups in different regions for a single HTTP or HTTPS listener. You can set traffic distribution ratios for the endpoint groups to control the traffic forwarded to each group.

Additionally, pay-as-you-go standard GA instances now offer these capabilities:

You can configure traffic distribution for virtual endpoint groups that are associated with HTTP and HTTPS listeners.
You can associate custom forwarding rules with multiple default or virtual endpoint groups. You can select only one endpoint group in each region. You can also write request IDs to headers.
You can specify a domain name for health checks.

Pay-as-you-go standard GA now integrates with Anti-DDoS

New

Pay-as-you-go standard GA instances now integrate with Anti-DDoS. Using Alibaba Cloud's global scrubbing centers, this feature provides terabit-level DDoS protection for the secure CNAME (secure accelerated IP address) of a GA instance.

Pay-as-you-go standard Global Accelerator instances now support Anycast Elastic IP Address

New

Pay-as-you-go standard Global Accelerator instances now support Anycast Elastic IP Address as a type of accelerated IP address.
