Serverless Database
A serverless database is a cloud-based database service that automatically manages infrastructure, scaling, and maintenance, allowing developers to focus on application logic without provisioning or managing servers. It typically operates on a pay-per-use model, scaling resources up or down based on demand, and includes built-in high availability and fault tolerance. Examples include services like Amazon Aurora Serverless, Google Cloud Firestore, and Azure Cosmos DB in serverless mode.
Developers should use serverless databases for applications with variable or unpredictable workloads, such as web apps, mobile backends, or IoT systems, to reduce operational overhead and costs by eliminating idle capacity. They are ideal for rapid prototyping, microservices architectures, and scenarios where automatic scaling and minimal maintenance are priorities, though they may have limitations for high-throughput or latency-sensitive use cases compared to traditional databases.
