Do we need a serverless framework? With Python, I did not
The document discusses the need for a serverless framework, emphasizing the benefits of cost reduction, flexibility, and streamlined operations in a serverless computing model where cloud platforms execute user functions. It highlights the use of various tools for deployment and management, including claudia.js and zappa, while noting the challenges of provider independence and the importance of good architecture and testing practices in this context. Ultimately, the author advocates for Python as a suitable runtime for serverless applications.
