Introducing Dedicated Load Balancer (Beta)

Flexible Engine
Release Notes

May, 2022

A new version of the Elastic Load Balancer service called Dedicated Load Balancer will be available in Beta phase during the 1st half of May 2022. The service is not yet covered by SLAs during the Beta phase period and may be discontinued for upgrade purposes. During the Beta phase, the service is available for free to all Flexible Engine customers. The Beta phase is expected to end at the end of June 2022, at which time the service will be fully available.

Each Elastic Load Balancer service has its advantages for different requirements:

  • The Shared Load Balancer is suitable for high-traffic Web services. This type of load balancer is able to shift requests based on domain names or URLs to meet your needs. Resources are shared between load balancers, and the performance of one load balancer instance can be affected by other load balancer instances. The Shared Load Balancer service was previously called Enhanced Load Balancer.
  • The Dedicated Load Balancer service allows you to have exclusive use of resources, so the performance of a dedicated load balancer instance is not affected by other load balancer instances. In addition, a wide range of specifications is available for selection. Dedicated load balancers offer more powerful transfer performance, support cross-AZ deployment and dual IPv4/IPv6 stack.

More information is available in the service description, user manual or from our support team.
