Serverless computing represents a shift in application deployment where the underlying server infrastructure is abstracted, allowing developers to focus solely on writing code, which is executed by cloud providers like AWS, Azure, or Google Cloud Platform in response to events. This model contrasts with microservices, as serverless functions are deployed independently and billed based on actual usage, offering potential cost savings especially for sporadically used services. While serverless architecture facilitates scalability and reduces administrative overhead, it may not suit all applications, particularly those requiring continuous operation or complex function management. Couchbase Server integrates with major serverless platforms, providing flexible, scalable NoSQL database solutions without vendor lock-in, and supports a variety of programming languages through its SDKs, making it a versatile choice for cloud-based applications.
