Introduction to the Serverless paradigm

A
Alex Casalboni

The document introduces the serverless paradigm, emphasizing its key characteristics such as zero administration and pay-per-execution. It discusses common misconceptions, asserts the importance of microservice principles, and details AWS Lambda capabilities and use cases. Additionally, it outlines organizational patterns for serverless architectures, distinguishing between nanoservice, microservice, and new monolithic patterns, while mentioning other cloud platforms supporting function as a service.
