Azure Cosmos DB Updates – May Highlights

Azure Cosmos DB updates were in abundance at Microsoft Build, so here is a quick run through of our highlights along with links for further reading.

Serverless – Generally Available

Announced in preview in Build 2021, this has now hit general availability. This new tier goes a long way for optimising costs in applications that have spiky traffic patterns. Rather than trying to predict the throughput, simply choose the serverless option and you will only be charged for the resources consumed by your database operations.

Expanded Throughput and Storage for Free Tier – Generally Available

The free tier request units per second have now gone up from 400 to 1,000 and the monthly storage has been raised from 5 GB to 2 GB in a generous move by the Azure Cosmos DB team. If you already use a free account this will have been applied automatically.

Always Encrypted – Preview

Announced into preview, always encrypted allows developers to encrypt data in the client application before storing it in the cloud. This extra level of protection is perfect for those working with confidential and sensitive data and for those needing to comply with regulatory requirements.

Integrated Cache – Preview

Another way to optimize costs is coming soon with Azure Cosmos DB integrated cache. This is an in-memory cache that doesn’t require writing any code. This helps guarantee manageable costs and low latency reads as request volume grows.

Partial Document Update – Private Preview

Partial document update will help reduce network payload and lower latency by replacing a full read-replace with path-level document changes when only portions of a document get updated.
