Serverless computing has evolved from a buzzword into a mainstream architectural choice for building scalable, efficient applications. While AWS Lambda has been the poster child for this movement, the serverless ecosystem is rapidly expanding beyond a single platform. Developers and SaaS teams now have access to a range of options that cater to more complex workloads, multi-cloud strategies, and specialized use cases. The next wave of serverless isn’t just about running small functions — it’s about building entire systems without the traditional infrastructure headaches.
