Note
  • Alibaba Cloud Elasticsearch no longer provides data nodes with 1 vCPU and 2 GiB of memory or data nodes with 2 vCPUs and 2 GiB of memory due to inventory issues and the impact on performance stability. Existing data nodes with these specifications are not affected.
  • Data nodes with 1 vCPU and 2 GiB of memory are designed only for testing purposes. Do not use clusters that contain such data nodes for production purposes. The service-level agreement (SLA) does not apply to these clusters. Therefore, we recommend that you upgrade your data nodes with 1 vCPU and 2 GiB of memory.
  • Data node specifications supported in different regions may vary. The specifications on the buy page or the specifications provided in Pricing of Alibaba Cloud Elasticsearch prevail.
