Azure Search Pricing

Search-as-a-service for web and mobile app development

Azure Search is search-as-a-service that helps developers build sophisticated search experiences into web and mobile applications, reduce the friction and complexity of implementing full-text search, and differentiate their application by leveraging powerful features not available with any other search package. With Azure Search a developer can integrate search, one of the most popular navigation methods, into their application more easily than they could by running their own search package. They also get access to rich and powerful capabilities to enhance the search experience and tie results to business objectives.

Pricing Details

Offered in combinable units that include reliable storage and throughput, Azure Search allows developers to set-up and scale a search experience quickly and cost-effectively. As the volume of data or throughput needs of an application change, Azure Search can scale out to meet these needs and then scale back down to reduce costs. To get more performance, a customer can combine units to gain more QPS or a higher document count or both. Units can also be combined to enable high availability or faster data ingestion.

High density (HD) mode is an optional setting available for Standard S3. High density mode enables customers to pack in a higher number of indices per Search service. This is ideal for customers building multi-tenant SaaS apps that have a large number of small tenants, trials, or free accounts and want to provide a powerful search experience at a low cost per index.

1 Queries per second and documents hosted, are based on target latency level of 350 milliseconds for reference data set. Actual performance may vary depending on data set and specific query used. For more information, please see documentation

2 Monthly price estimates are based on 31 days per month.

3 High Density (HD) mode is an option available within the Standard S3 service that allows larger number of indexes to be created in a single service. Using HD mode, a service can create up to 1000 indexes / partition where an index may be no more than 1 million documents (or 2 GB storage) and the total number of documents and storage across all indexes may not exceed 120 Million documents / partition or 200 GB / partition.

FAQ

  • With Microsoft Azure Search, you are billed on a flat, predictable hourly rate based on the number of units that have been used during any given hour.

  • You are billed the maximum number of search units provisioned during any hour. If you start with two units and scale to four units and scale back down to two units all within an hour, you will be charged for four units.

  • The stop button is meant to stop traffic to your service instance. As a result, your service is still running and will continue to be charged the hourly rate.

  • You are billed the flat rate for each hour the unit exists, regardless of usage or if the unit is active for less than an hour. For example, if you create a unit and delete it 5 minutes later, your bill will reflect a charge for 1 unit hour.

  • Azure Search Units combine to provide additional throughput and storage. For example, to scale from 15MM documents to 30MM (additional partitions), a customer can purchase two units. To increase throughput (additional replicas), they can purchase two units. To increase both storage and throughput, a customer would need to purchase four units (2 replicas x 2 partitions = 4 search units).

  • Free is a free version of Azure Search designed to provide developers a sandbox to test features and implementations of Search. It is not designed for production workloads. Basic and Standard are the go-to options for building applications that benefit from a self-managed search-as-a-service solution. Standard delivers storage and predictable throughput that scales with application needs. For very high-demand applications, please contact azuresearch_contact@microsoft.com.

  • Microsoft Azure Search is available in the new Microsoft Azure portal. First you must sign up for a Microsoft Azure subscription. Once you sign up for a Microsoft Azure subscription, you can add a Search account to your Azure subscription via the Gallery in the Preview Portal.
