Introduciendo Serverless en Proyectos Python
This document discusses introducing serverless architectures to Python projects. It begins by showing the growth in popularity of serverless technologies. It then discusses using AWS Lambda for periodic scripts, tasks, and small HTTP APIs. It provides code examples of packaging and deploying Python code to AWS Lambda. It also discusses using services like AWS Lambda, CloudWatch Events and Celery to run periodic tasks like backups and reports. Overall it presents serverless as a way to run scripts, tasks and small APIs without managing servers.
