Today, we are excited to announce general availability of the S3 tier of service! The S3 tier of Azure Search is designed to handle large volumes of documents and heavy traffic. Identically priced and backed by the same high performance CPUs and SSD storage, the S3 tier comes in two configurations: S3 and S3 High Density (HD).
S3
The standard S3 tier of Azure Search is suited for customers with large numbers of documents and can handle many hundreds of queries per second. With each partition supporting 120 million documents (or 200 GB), it is possible to search up to 1.4 billion documents (or 2.4TB) in a single search service while still maintaining low latency for high query volumes.
S3 High Density
The S3 HD tier is targeted at ISVs and SaaS providers who build applications which support a large number of relatively small indexes in a single search service. In fact, Microsoft Dynamics 365 has been using Azure Search’s S3 HD tier to power its search experience for thousands of its online customers:
“Dynamics 365 (online) took a huge leap forward and paved the way for significant future search innovation by leveraging Azure Search. Delivering a high level of performance and functionality, the S3 HD SKU makes it straightforward and cost-effective to manage Azure Search for thousands of Dynamics 365 customers.”
– Mike Carter, Principal Program Manager, Dynamics 365
In a single S3 HD service, there can be up to 3,000 indexes which can each support 1 million documents which makes it an attractive option to support numerous smaller applications with many low-cost indexes. You can read more about multitenant applications and Azure Search.
