| description.long | Confluent Cloud is a managed Kafka service that automates infrastructure management and scaling across multiple cloud providers. It combines Kafka for streaming data with integrated Apache Flink for stream processing, providing enterprise-grade security, hundreds of pre-built connectors, and usage-based pricing with no upfront capacity provisioning required. | Inngest enables developers to write durable functions with built-in checkpointing and retry logic that survive failures. Functions execute step-by-step with automatic recovery and detailed observability, eliminating the need for manual infrastructure management. |
