With the rise of cloud computing and modern distributed systems, we also witnessed the rise of a new practice area: DevOps. Despite being fundamental for smooth cloud operations, a dedicated DevOps practitioner is a luxury most teams can’t afford. Salaries average $130K in San Francisco, for example. When a dedicated DevOps practitioner is not available in our team, what should we do? The answer could unfold a multitude of aspects.

Web proxies intercept traffic from your systems as they move to other systems, analyze the packets, then send the data along. There are a lot of reasons why you might want to intercept packets. Originally the main use case for a proxy was as a caching server. In this use case, the first time a person in your network goes to a website, the static content (particularly graphic images) gets downloaded and cached. Then, because the content is local, the next person to hit that site will get a fast response.

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.

Canonical today announced full enterprise support for Kubernetes 1.18, with support covering Charmed Kubernetes, MicroK8s and kubeadm. Committed to releasing in tandem with upstream Kubernetes, enterprises can benefit from the latest additions to enhance their day to day operations.

Uh oh, the site’s certificate has expired. How do we generate a new one? Where’s the private key? Which servers need the new cert? What even goes in the cert? If this sounds all too familiar, rest assured you’re not alone. Outages due to expired certs are far too common and it happens to sites of all sizes (one recent example includes Microsoft Teams going down for several hours due to an expired cert). Disruptions like this are entirely preventable with proper monitoring in place.
