Docker has changed the way we build, package, and deploy applications. But this concept of packaging apps in containers isn’t new—it was in existence long before Docker. Docker just made container technology easy for people to use. This is why Docker is a must-have in most development workflows today. Most likely, your dream company is using Docker right now. Docker’s official documentation has a lot of moving parts. Honestly, it can be overwhelming at first.

Globally, cybercrime was the second most reported crime in 2016, and cybercrime damages are anticipated to cost businesses and organizations $6 trillion annually by 2021. One of the ways that cybercriminals attack businesses is through the use of web application vulnerabilities. A web application vulnerability is a flaw or loophole in an application’s code that can be exploited by attackers to facilitate cybercrime. Imperva reports that web application vulnerabilities are on the rise.

There’s a new shapeshifting strain of Android malware in the mix. It replaces legitimate apps with compromised ones and is imaginatively named Agent Smith after the iconic villain in The Matrix.

Open source is one of the key drivers of DevOps. The need for flexibility, speed, and cost-efficiency, is pushing organizations to embrace an open source-first approach when designing and implementing the DevOps lifecycle. Monitoring — the process of gathering telemetry data on the operation of an IT environment to gauge performance and troubleshoot issues — is a perfect example of how open source acts as both a driver and enabler of DevOps methodologies.

The other day whilst using a very popular website I came across a series of 404 unavailable page messages. I didn’t think much about it at the time but on reflection it made me wonder how many people actually understand what different error codes mean? Hands up, I only know a few and I work in the website monitoring sector. To most, it just means a weird IT message when things go wrong.

Technology is changing the world faster than ever. Thanks in part to the rise of the Software-as-a-Service (SaaS) model, customers have come to expect the apps they use to be accessible at all times.
