Starting from February 5, 2021, MySQL will officially no longer provide follow-up update and maintenance of MySQL 5.6, but Alibaba Cloud RDS MySQL 5.6 will continue to provide update and maintenance services, extending for three years to February 05, 2024.
PolarDB MySQL 5.6 is not affected, and Alibaba Cloud will continue to provide support for this version.
Alibaba Cloud recommends that you purchase an instance of RDS MySQL 5.7 or 8.0. If you need to purchase a new instance of RDS MySQL 5.6 version, all RDS MySQL 5.6 version instances can continue to be used normally, and the Alibaba Cloud RDS team will continue to provide update and maintenance services.
It is recommended that you upgrade RDS MySQL 5.6 to 5.7 or 8.0, or migrate RDS MySQL 5.6 to PolarDB MySQL (5.6, 5.7 or 8.0) before the extension expires. You need to create a new instance of RDS MySQL 5.7 or 8.0, or PolarDB MySQL (5.6, 5.7 or 8.0) and then migrate data to the new instance through Data Transmission Service (DTS). For detailed steps on migration, please refer to the following guides:

AnalyticDB for MySQL elastic mode is released on the international site to support the features of elastic plan, resource group isolation and tiered storage.
Elastic plan is a good feature for adapting the compute resource to the fluctuation of analytical business workload to achieve a balance between cost and flexibility. As shown in the figure below, there are 3 obvious intervals of analytical business load in a day, of which 08:30 am to 11:30 am is the business peak, other times are relatively stable. Set the corresponding elastic plan, the processing capacity is upgraded to 256 cores meets the business processing capacity requirements at the peak time, and the processing capacity falls back to 64 cores at other times saves cost. The granularity of the elastic plan supports hour, day, and week period settings.
For detailed information about the elastic plan, please refer to：https://www.alibabacloud.com/help/doc-detail/189507.htm
Resource group isolation is very convenient for "one copy of data, multiple workload scenarios" within a cluster. In the computing layer, multiple stateless resource groups can be extended. The computing resources for each resource group are isolated and do not affect each other. Each resource group can be specifically bound to a business workload.
For example, we can define 3 resource groups: a group for interactive analytics, a group for batch jobs, and a group of machine learning interactive jobs.
For detailed information about resource group isolation, please refer to: https://www.alibabacloud.com/help/doc-detail/189504.htm
Hot (ESSD), warm (ESSD + OSS hybrid mode), cold (OSS) tiered storage is suitable for users to choose a suitable cost-effective storage method according to different business scenarios. For example, in the figure below:
