Stream Big on Azure: Announcing DeltaStream Early Access for Microsoft Azure
We are thrilled to announce a milestone that has been one of our top customer requests: DeltaStream is now available for Early Access (EA) on Microsoft Azure.
Data teams operating in the Azure ecosystem can build, manage, and scale sophisticated, stateful streaming data pipelines from end to end using only SQL. This release is a major step in our mission to make powerful stream processing simple, accessible, and truly serverless—no matter where your data lives.
The Real-Time Challenge in the Azure Ecosystem
The Microsoft Azure stack is a powerhouse for data. Teams rely on Azure Event Hubs for high-throughput data ingestion and Azure Data Lake Storage (ADLS) Gen2 for building massive, cost-effective data lakes. Combined with services like Azure Synapse Analytics and Microsoft Fabric, it's a world-class analytics platform.
But a critical gap exists: the real-time processing layer that connects ingestion to analytics.
Until now, data teams faced a difficult choice:
- Manage Complex Clusters: Use powerful but operationally heavy platforms like Apache Spark or Flink. This requires a dedicated team of specialized engineers, high costs for idle clusters, and a steep learning curve.
- Default to Batch: Give up on real-time. Teams are forced to run batch ETL jobs every 15 minutes, 30 minutes, or even hourly, delivering stale data to the business.
We believe Azure users deserve a better option. You shouldn't have to be a distributed systems expert to build a real-time medallion architecture.
DeltaStream: The Serverless Streaming Layer for Azure
DeltaStream is the serverless, SQL-native stream processing platform that bridges this gap. We provide the power of a complex streaming engine with the simplicity of SQL, all delivered through flexible deployment models that fit your needs.
- 100% SQL-Native: If you and your team know SQL, you can now build and manage robust streaming pipelines. Create streams, tables, and materialized views using the language you already know. No Java, Scala, or Flink expertise is required.
- Powerful Stateful Processing: Go far beyond simple ETL. Perform time-windowed aggregations (e.g., "count clicks by user in the last 5 minutes"), join your real-time Event Hub stream against a reference table, and materialize those results for downstream consumption.
Flexible Deployment: SaaS or Your Own VNet (BYOC)
We understand that every enterprise has different security and governance requirements. That's why DeltaStream on Azure is available in two models:
- SaaS (Software-as-a-Service): The simplest way to get started. This is our fully managed, multi-tenant environment. You get all the power of DeltaStream without managing any infrastructure—just connect to your Azure sources and sinks, and we handle the rest.
- BYOC (Bring Your Own Cloud): For organizations with strict data residency and security needs. DeltaStream deploys its serverless data plane directly inside your Azure subscription (in your VNet). This ensures your data never leaves your network boundary, giving you the full security and governance of your own environment, but with the simplicity of a managed serverless platform.
This flexibility empowers all Azure customers—from fast-moving startups to security-conscious enterprises—to build the real-time use cases they’ve always wanted with a fraction of the cost and complexity.
Join Our Early Access Program
We are now opening our Early Access program for a select group of Azure customers.
EA participants will be the first to build production-grade streaming pipelines on Azure with DeltaStream, and they will work directly with our founding engineering and product teams to help shape the future of our Azure integration.
