A month and a half ago we released ValidKube, our first OS project that fused the capabilities of three other popular OS tools (kubeval, kubectl-neat and trivy) in a single easy-to-use microsite. Using the microsite, any user could ensure the security and hygiene of their K8s YAML, with just a few clicks of the button, pretty much on the fly. ValidKube was born out of a straightforward concept and we were happy to see its user-friendly approach resonate almost immediately.

One of the most challenging things when writing about DevOps and ITIL is finding the perfect phrases to define both of them. They not only mean different things to different people and organizations but are also implemented & used very differently. Let’s glance through their definitions first.

The past two years have seen erratic cloud spend thanks to the upheaval caused by the global pandemic. Looking ahead to 2022, business is beginning to normalize. Within that “new normal,” there is no question that cloud is more popular than ever, and Kubernetes is at an all-time high. Some companies are continuing to operate remote, or find that they are thriving thanks to an investment in the cloud.

You know you need to secure your software supply chain. Everyone’s telling you that these days - your executives, your vendors, even the United States government. Your organization has an initiative to do so, or maybe they’ve brought in an expert to help you achieve this goal. But hold on a minute - do we have a shared understanding of what a software supply chain is, and what exactly makes it secure?

March 29th, 2022—Canonical, the publisher of Ubuntu, announces that Firmus, the Australian cloud infrastructure provider that is revolutionising data centre technology, has built its ultra-efficient and sustainable public cloud on Canonical’s Charmed OpenStack and Charmed Kubernetes.

A brownout is an intentional but temporary disruption of service. Why would a company purposely cause a brownout and when does it make sense? In this post I will explain the what and why of brownouts, and provide some recent examples.

When building an incident response process, it’s easy to get overwhelmed by all the moving parts. Less is more: focus first on building solid foundations that you can develop over time. Here are three things we think form a key part of a strong process. I’d recommend taking these one at a time, introducing incident response throughout your organisation. Just being honest: we’re a startup selling incident management software.

Kubernetes is a rich ecosystem, and the native YAML or JSON manifest files remain a popular way to deploy applications. YAML’s support for multi-document files makes it often possible to describe complex applications with a single file. The Kubernetes CLI also allows for many individual YAML or JSON files to be applied at once by referencing their parent directory, reducing most Kubernetes deployments to a single kubectl call.

Deployment is an essential stage of any software development project. With the fast-paced modern agile software development needs, deployment frequency increases rapidly. Although it looks very appealing to often release due to its positive impact on customer satisfaction and improved customer engagement, it is risky at the same time. What if the deployment goes wrong on production?
