What are Microservices?

Nearly every computer system performs multiple tasks using shared resources, and one of the questions of computer programming is how closely the bits of code that perform those tasks should be tied to one another. An increasingly popular answer is the concept of a microservice—a small, discrete chunk of

This is how Sofware as a Service (SaaS) Transformed Software Development

Back in the early days of the internet, there weren’t many internet applications. Instead, applications were overwhelmingly written for the Windows, Linux, and Macintosh operating systems. “Software delivery” often meant copying a binary to a server or building a blue-screen Windows installer and making that available on a CD-ROM

What is Python?

Dating from 1991, the Python programming language was considered a gap-filler, a way to write scripts that “automate the boring stuff” (as one popular book on learning Python put it) or to rapidly prototype applications that will be implemented in other languages. However, over the past few years, Python has
