ETAS and Microsoft team up to speed up automotive software development with cloud calibration tools
Press release, 13 December 2025
German automotive software tools provider ETAS and tech giant Microsoft have announced a strategic collaboration to transform how automotive software is developed, calibrated, and tested — by bringing ETAS’s advanced calibration tool suite to the Microsoft Azure cloud platform. This move is designed to dramatically speed up automotive software workflows, reduce reliance on costly local hardware, and help engineers and OEMs (original equipment manufacturers) build the next generation of vehicle software far more efficiently.
Traditionally, developing and calibrating automotive control software — the code that runs everything from engine management to advanced driver assistance systems — relies on powerful local machines and complex toolchains. ETAS is known across the auto industry for its suite of calibration and data tools, including the ETAS Calibration Suite, Data Operator, ETAS Analytics Toolbox (EATB), and Advanced Simulation and Calibration Model (ASCMO). Under the new partnership, these flagship products will be made available directly through the Microsoft Azure Marketplaceand tightly integrated with Azure’s scalable cloud infrastructure, marking the first time ETAS calibration tools can be used natively in the cloud.
By migrating these tools to Azure, automotive developers can automate calibration tasks, collaborate more seamlessly across teams, and leverage the nearly unlimited compute power of cloud environments to run simulations and analyses that would be slow or impractical on traditional workstations. Engineers will be able to detect issues earlier in the development cycle, iterate faster, and ultimately shorten the time it takes to bring new software functions to production vehicles. The cloud deployment also aligns with broader industry trends toward software-defined vehicles, where frequent updates, complex feature stacks, and over-the-air capabilities require robust, flexible development pipelines capable of handling large data volumes and advanced analytics.
This collaboration goes beyond merely hosting tools in the cloud. ETAS and Microsoft are building out a cloud-centric calibration and validation ecosystem that supports advanced workflows — such as automated testing sequences, cross-team version control, and integration with other cloud-native development services. Access to Azure’s high-performance infrastructure means automotive teams can scale their work up or down based on project needs, reduce hardware costs, and free up physical resources previously tied up by intense computation tasks. According to company statements, this will also enable earlier identification of software faults and more efficient handling of calibration data, which becomes increasingly important as vehicles grow more software-intensive and functionally complex.
Another key benefit of the cloud approach is enhanced collaboration among global engineering teams. Vehicle software development often involves specialists spread across multiple countries and companies. With ETAS’s tools on Azure, teams can collaborate in real time, share results across distributed workflows, and access the same datasets and analytics dashboards without the need for local installations or cumbersome data transfers. This streamlined environment supports DevOps practices — a critical factor in modern software engineering that emphasizes continuous integration and delivery, rapid feedback loops, and automated verification.
The first preview of these cloud-hosted tools will be showcased at CES 2026, where ETAS plans to demonstrate how the integration with Azure can accelerate both development and calibration tasks for vehicles ranging from conventional powertrains to electrified and autonomous platforms. OEMs and Tier-1 suppliers in the automotive ecosystem are expected to benefit from quicker calibration cycles, improved test coverage, and greater flexibility in handling complex software stacks — features that are increasingly essential in an era where vehicles are defined as much by their software as by their hardware.
Overall, this partnership signals a shift in how automotive software is built and validated, leveraging cloud computing’s strength to tackle the growing complexity of modern vehicle systems. By combining ETAS’s deep expertise in automotive calibration with Microsoft’s powerful cloud platform, the collaboration aims to help the industry meet the demands of future mobility — where faster development, cloud scalability, and robust data workflows will be key differentiators in the race to deliver safe, reliable, and cutting-edge automotive software.
