ES is billed on a pay-as-you-go basis.
ES is a distributed cluster deployed in VPC which typically consists of 3 or more nodes. Each node contains computing resources (available with specified CVM models) and storage resources (SSD/premium cloud disk with a certain storage capacity).
Total fees for a cluster = Fees per node (compute fees + storage fees) * number of nodes
Hardware devices of different specifications come with different computing capabilities to meet the diverse requirements for cluster write and query performance. In addition, ES offers multiple editions of Elastic Stack. Specifically, the Basic Edition and Platinum Edition contain Elasticsearch's official commercial features (formerly X-Pack). The pricing of node models varies by the Elastic Stack edition. For more information, see Product Pricing.
ES currently uses SSD and premium cloud disks as the storage media for ES clusters to ensure overall performance of data writes, queries, and reads as well as data security.
