Streaming data platforms have become foundational technologies for enterprises seeking to process, enrich and act on event data as it is generated. Organizations increasingly rely on streaming data capabilities to support real-time decision-making, event-driven architectures and AI-enabled automation across distributed environments. The convergence of streaming, analytics and AI is accelerating the shift from batch-centric processing toward continuous, responsive data operations.
Software Provider Summary
The ISG Buyers Guide™ for Streaming Data evaluates 25 software providers offering products that support event streaming, stream processing and governance of data in motion. The research ranked the top three overall leaders as Databricks, AWS and Microsoft. Providers were classified using weighted performance in Product Experience and Customer Experience for ISG quadrant placement. AWS, Cloudera, Confluent, Databricks, Google Cloud, Huawei Cloud, IBM, Microsoft and MongoDB were rated Exemplary, with Alibaba Cloud, Cloud Software Group, Palantir and Redis rated Innovative. Actian, Oracle, Salesforce and Solace were rated Assurance, and Aiven, Broadcom, Cumulocity, KX, Red Hat, SAS, Siemens and Tencent Cloud were rated Merit.
Product Experience Insights
Product Experience, representing 80% of the evaluation, focuses on Capability (50%) and Platform (30%), including adaptability, manageability, reliability and usability. Databricks, Confluent and AWS achieved the highest performance as Leaders in this category, supported by event streaming infrastructure and stream processing capabilities combined with stream governance and AI support for real-time data operations. Leaders demonstrated enterprise-grade platform capabilities across varied streaming, integration and operational data management contexts.
Customer Experience Value
Customer Experience, representing 20% of the evaluation, focuses on validation and TCO/ROI. AWS, IBM and Oracle were the Leaders in this category, demonstrating strong customer commitment and clear dedication to customer needs. Providers with lower performance often lacked sufficient information to demonstrate customer success, articulate commitment to customer experience or communicate measurable value through TCO/ROI.
Strategic Recommendations
Enterprises should evaluate streaming data platforms based on their ability to support scalable event processing, governance and integration across today’s data architectures. Assessment should prioritize stream processing performance, governance maturity, observability, AI integration and support for both stateless and stateful workloads. Organizations should also evaluate how effectively providers unify data in motion and data at rest while enabling real-time automation, analytics and intelligent applications.
The software providers and products evaluated in this research offer product and customer experiences, but not every feature is equally valuable to every enterprise or is needed to support the relevant business processes and use cases. Moreover, having too many product capabilities may be a negative factor for an enterprise if it introduces unnecessary complexity. Nonetheless, you may decide that a more comprehensive set of capabilities is important and meets your enterprise’s requirements.
An effective customer relationship with a software provider is vital to the success of any investment. The overall customer experience and the full lifecycle of engagement play a key role in ensuring satisfaction and long-term success. Providers with dedicated customer leadership, such as chief customer officers, tend to invest more
The research finds Databricks atop the list, followed by AWS and Microsoft. Providers that place in the top three of a category earn the designation of Leader. AWS and Databricks have done so in four categories, Confluent and Oracle in two and IBM, Microsoft and Palantir in one category.
