Learn snapcraft by example - multi-app client-server snap

Over the past few months, we published a number of articles showing how to snap desktop applications written in different languages – Rust, Java, C/C++, and others. In each one of these zero-to-hero guides, we went through a representative snapcraft.yaml file and highlighted the specific bits and pieces developers need to successfully build a snap. Today, we want to diverge from this journey and focus on the server side of things.

Securing open source through CVE prioritisation

According to a recent study, 96% of applications in the enterprise market use open-source software. As the open-source landscape becomes more and more fragmented, the task to assess the impact of potential security vulnerabilities for an organisation can become overwhelming. Ubuntu is known as one of the most secure operating systems, but why? Ubuntu is a leader in security because, every day, the Ubuntu Security team is fixing and releasing updated software packages for known vulnerabilities.

Building a Raspberry Pi cluster with MicroK8s

The tutorial for building a Raspberry Pi cluster with MicroK8s is here. This blog is not a tutorial. This blog aims to answer; why? Why would you build a Raspberry Pi cluster with MicroK8s? Here we go a little deeper to understand the hype around Kubernetes, the uses of cluster computing and the capabilities of MicroK8s.

Episode 7: Provisioning Linux Machines With Ansible

It's time to provision our Request Metrics server. There is some common configuration that applies to all Linux servers. We want this base configuration regardless of what that specific server is doing. This a great use case for an Ansible role. Our "linux-common" role includes these among other things:

What Is Syslog? Everything You Need to Know

For those out there searching for “What is syslog?,” this post has answers to all of your questions. Simply put, syslog handles a very important task—collecting events—and is present in almost all systems and peripherals out there.
