This is the second article in our open source series. After having briefly discussed the history of open source in the first article, let’s focus now on the several dimensions or layers of FOSS (Free and Open Source Software). We won’t linger much on the development side here. Obviously, coding is a large part of Free and Open Source Software (FOSS) but it’s only the tip of the iceberg. As we wrote in the first post of this Open Source Series, the evolutions of both FOSS and of the Internet are interleaved and interrelated. One of the biggest disruptions that FOSS created regarding coding is collaborative development. FOSS generated several methods and tools to coordinate and organize projects with many developers spread around the globe. Distributed Versionning Systems like Git , bug and case management systems like BugZilla , continuous integration and nightly builds, quality tools like SonarQube , etc. Today, all these tools have been adopted into our companies and are used every day as commodities by enterprise developers to design, build and implement industrial development pipelines. More recently, FOSS reinforced this trend with DevOps tools and methods, largely promoted by Open Source native companies like the Internet giants. So yes, FOSS is a major source of IT industrialization and will continue to be so.

Introduction

“Linux is a cancer”, “Open source sofware is not sure and not secured”… Nowadays these affirmations sound weird, but a decade ago we could hear that kind of affirmations by some people working in IT. Currently, Open Source is everywhere, not only in software. This article is the first part of a series dedicated to Open Source’s world. In this first article we will cover the history from the beginning up to the mass market deployment.

Introduction

Monitoring, the practice of observing systems and determining if they are healthy, is hard and getting harder. There are many reasons for this: we are managing many more systems (servers and applications or services) and much more data than ever before, and we are monitoring them in higher resolution: it is not only possible but desirable to monitor practically everything we can, so we are also monitoring many more signals from these systems than we used to.
