Release Notes

September, 2022


We are pleased to announce you that the Dedicated Load Balancer launched in Beta mode during the 1st half of May 2022 is now in general availability. The service is now fully supported. You can find the price list on Flexible Pricing list.  

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

  • Shared Load Balancer is suitable for web services with heavy traffic. This type of load balancer is capable of forwarding requests based on domain names or URLs to meet your needs. Resources are shared among load balancers, and the performance of a load balancer instance may be  affected by other load balancer instances. Shared Load Balancer service was previously named Enhanced Load Balancer.  
     
  • Dedicated Load Balancer allows you to have exclusive use of resources, so that the performance of a dedicated load balancer instance is not affected by other load balancer instances. In addition, there is a wide range of specifications available for selection. Dedicated Load balancers provide more powerful forwarding performance, support cross-AZ deployment and IPv4/IPv6 dual stack. 
     

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