Confluent's serverless Apache Flink service abstracts away the underlying infrastructure and provides a fully managed environment for stream processing applications, empowering users to focus on app development without operational overhead. The service offers elastic autoscaling with scale-to-zero, evergreen runtime and APIs, and usage-based billing, reducing infrastructure costs and providing accurate billing based on fluctuating usage. The serverless architecture is designed to pass dynamic billing features and benefits on to users, making mixed workloads, including variable and short-lived explorative workloads, very cost-effective. The service provides fast rescaling with sub-second rescaling, minimizing downtime duration driven by how much time it takes to repartition the state into the new degree of parallelization before restarting the Flink job. With a base price of $0 for compute pools and no additional charges for state management or networking, users can take advantage of accurate usage-based billing and efficient resource allocation, resulting in cost savings.
