Billing methods
Billing method | Description |
Subscription | If you use this billing method, you are charged when you create an instance. This billing method is more cost-effective than the pay-as-you-go billing method. A subscription instance cannot be released within the subscription period. You cannot change the billing method of an instance from subscription to pay-as-you-go. |
Pay-as-you-go | If you use this billing method, you are charged per hour based on your actual resource usage. All the hourly-fee bills belong to the same purchase order and the fees are deducted from the balance of your Alibaba Cloud account. You can change the billing method of an instance from pay-as-you-go to subscription. |
Pricing (general fees)
OpenSearch High-performance Search Edition provides four types of application instances for you to use in different scenarios. The billable items of application instances include the instance leasing duration, storage capacity, and computing resources. The fee is calculated by using the following formula: Total fee = Fee of instance leasing + Fee of storage + Fee of computing resources.

Storage capacity: 10 GB to 500 GB. | 1,000 LCUs and 10 GB | 271.38 | 5.19 | 335.11 |
Exclusive cluster - storage-optimized | All the purchased cluster resources are independently deployed, and you exclusively own these resources. The cluster provides high-specification storage resources, and is suitable for scenarios that require large storage space. | Computing resources: 500 LCUs to 2,000 LCUs. Storage capacity: 500 GB to 2,000 GB. | 500 LCUs and 500 GB | 254.77 | 1.38 | 28.25 |

Note:
Reference instance types in OpenSearch API and SDKs: When you use OpenSearch API or SDKs to create an application instance or query details of an application instance, you can specify or obtain the instance type in the spec field of the quota parameter. Valid values of the spec field: opensearch.share.common, opensearch.private.compute, opensearch.private.storage, and opensearch.private.common. They indicate the instance types of shared cluster - compute-optimized, shared cluster - storage-optimized, shared cluster - general-purpose, exclusive cluster - compute-optimized, exclusive cluster - storage-optimized, and exclusive cluster - general-purpose, respectively.
Billable items: Billable items for application instances include the instance leasing duration, storage capacity, and computing resources. For a pay-as-you-go application instance, the billable items are represented as consumption.portal.opensearch.spec/buytype, consumption.portal.opensearch.doc_size/storage, and consumption.portal.opensearch.compute_resource/compute. For a subscription application instance, the billable items are represented as buytype, storage, and compute.

Quota selection:
Item | Description | Estimation method |
Storage capacity | The storage capacity used by documents that are synchronized to OpenSearch. | The required storage capacity is estimated based on the total number of bytes that you will store in your OpenSearch application instance. |
Computing resources (LCU) | LCUs are used to measure the computing power of a search service. An LCU indicates the computing power of 0.01 core in a search cluster. | Total number of LCUs = Queries per second (QPS) × Number of LCUs consumed in each query. The number of LCUs consumed in each query can be obtained from search tests. |
When you select a storage quota for the first time, we recommend that you multiply the number of documents by the number of bytes in a document with an average size to estimate the total number of bytes. This way, you can estimate the storage quota that you need.
When you select a computing resource quota for the first time, we recommend that you select the minimum quota of the instance type. After your application instance is created, you can test the application instance and view the LCU information in CloudMonitor. You can increase the computing resource quota as needed.
An instance upgrade or downgrade immediately takes effect and does not affect the search service.
