Implementing Serverless Node.js Functions Using Google Cloud

by Vignes Aruljothi

Serverless computing is an architecture style in which the code is executed in a cloud platform where we don’t need to worry about the hardware and software setup, security, performance, and CPU idle time costs. It's an advancement of cloud computing that goes beyond infrastructure that abstracts the software environment as well. It means no configuration is required to run the code.

Server-side I/O Performance: Node vs. PHP vs. Java vs. Go

by Brad Peabody

Understanding the Input/Output (I/O) model of your application can mean the difference between an application that deals with the load it is subjected to, and one that crumples in the face of real-world uses cases. Perhaps while your application is small and does not serve high loads, it may matter far less. But as your application’s traffic load increases, working with the wrong I/O model can get you into a world of hurt.
