Amazon MemoryDB for Redis – Where speed meets consistency
Posted on November 16, 2021, Level beginner Resource Length long
Modern apps are not monolithic; they're composed of a complex graph of interconnected microservices, where the response time for one component can impact the performance of the entire system. For instance, a page load on an e-commerce website may require inputs from a dozen microservices, each of which must execute quickly to render the entire page as fast as possible so you don't lose a customer. It's critical that the data systems that support those microservices perform rapidly and reliably, and where speed is a primary concern, Redis has always been top performer. By Dr. Werner Vogels.

Posted on October 21, 2021, Level intermediate Resource Length medium
If you're making an HTTP request in Node.js there's a good chance you'll want to cancel it if it takes too long to receive a response.
