Choosing Serverless Over Managed Services: When and Why to Make the Switch

The text discusses the benefits of serverless cloud services over managed services, using storage and stream processing as examples. In traditional on-prem environments, users must handle all operational aspects, including setting up clusters and managing resources, which can be both complex and costly. Even with managed cloud services like HDFS, users still face decisions about provisioning and resource management, leading to potential inefficiencies and extra costs. In contrast, serverless platforms like AWS S3 and DeltaStream abstract away these complexities, allowing users to focus on application development rather than infrastructure management. Serverless solutions provide scalability, isolation, and ease of use, as users only pay for resources they actively use, eliminating the need for resource over-provisioning. DeltaStream, in particular, offers a unified platform for stream processing and database functionalities, enabling seamless integration with streaming stores and real-time query execution without the concept of clusters, thus simplifying the user experience and optimizing costs.
