Stateful AWS Lambda with Redis® REST

The blog post discusses implementing a basic stateful API, specifically a page counter, using AWS Lambda and Upstash Redis through a REST API, addressing challenges associated with serverless architecture, such as statelessness and connection management. The serverless framework is used for deployment, and the project setup involves creating a database in the Upstash console, using node-fetch for API calls, and configuring the serverless.yml file to handle HTTP requests. The post emphasizes the benefits of serverless computing, like the pay-per-use model and reduced infrastructure maintenance, while also cautioning against the public sharing of API tokens and recommending best practices for performance, such as deploying in the same region and using a pipeline API for multiple commands.
