Serverless Infrastructure and API πβοΈ #54
Considerations and trade-offs, authorization and Architecture as Code to build Serverless APIs
In the previous issue, Serverless APIs are evolving πβοΈ #53 we looked into updates on the Serverless APIs front and some amazing things around APIs; also a poll to check about whatβs your preferred Serverless API with Amazon API Gateway leading it!
In this issue, we are continuing to explore the Serverless APIs while taking into consideration the Lambda Cold Starts, response streaming with Lambda function URL, AppSync for GraphQL APIs, cost-effective consideration and trade-offs!
And in other news IBM acquires Hashicorp.

Gregor Hohpe addresses if Serverless is an illusion in the world of abstractions where it removes the complexity for the developer but also shifts the complexity on the provider to make it as developer-friendly as possible with AaC (Architecture as Code).
Riley Peronto from Edge Delta writes about 10 methods to reduce AWS Lambda cost from memory considerations, reducing Cold Starts, and ARM-based processors to enabling monitoring and alerts for cost.
Martina Della Corte addresses the performance with Secrets Manager v/s Lambda Extenstion and uses the Lambda Power tuning tool to compare the results.
