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 such data nodes for production purposes. The service level agreement (SLA) does not apply to such data nodes. Therefore, we recommend that you upgrade your data nodes with those specifications at the earliest opportunity.
  • 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.
