So far in this series, you have learned why it’s important to understand how to use the command line, some command line basics and shell commands, and all about running CLI-based applications and command line tools. In this part of our CLI intro series, you are going to learn the basics of customizing your shell user experience. In this part of the CLI intro series, we’re going to focus on.

Calico v3.23 is out, and with it a lot of new features! This release marks a long-awaited milestone for me and my team, as it includes the Calico VPP data plane (beta). So now seems to be a good time to reflect on what this integration actually is, and why we built it.

It’s funny how even today, in 2022, people still ask me if WordPress is a good choice for a high-traffic website. There are few website-building solutions on the internet as tested as WordPress. And brands like TechCrunch and The New Yorker wouldn’t be hosted on WordPress if traffic was an issue. But here’s the thing: WordPress is self-managed. As a result, you as an individual or organization using it for your business are responsible for monitoring your WordPress site.

At this point in my career, I’ve realized the responsibilities of database administrators (DBAs) and database reliability engineers (DBREs) can differ from company to company, from year to year, and even from quarter to quarter.

Site Reliability Engineers (SREs) have a considerable set of tasks to juggle no matter where they work or how long their company has had an SRE practice. But if you’re the very first SRE to join an organization – as many SREs are these days, given that the SRE trend is trickling down into smaller and smaller companies – you face a special group of challenges. You may find it difficult to get buy-in for SRE from other technical teams.

Having trouble deploying Kubernetes in a highly available mode and have a backing remote database? This blog is for you. I will explain how to deploy K3s in HA configuration with an external database Postgres. K3s is a certified Kubernetes distribution for IoT and Edge computing. I deployed it on virtual machines in an IBM Z mainframe. Instead of etcd, I choose Postgres as my storage for my K3s clusters. I deployed Postgres in non HA mode.

It is an exciting time to be a startup. Our vast technological landscape has made powerful digital tools available to businesses of all sizes, making starting (and scaling) an organization easier than ever before. In an era where technology is a fundamental building block of almost every business, methodologies like DevOps have become ubiquitous across many industries.

To keep ahead of the curve, many organizations are looking at how to evolve their technical processes to accelerate their IT infrastructure development. Fast and robust deployments to the latest platforms are key to achieving the low lead times that enable this evolution. Two of the most widely-used technologies to host these deployments are serverless functions and containers. What are they, how do they differ, and how do you decide which is best for your application?

Let's say you’re already adhering to ITIL standards and an ITIL maintenance plan. That's excellent. But as we know, improvement is a “forever” process; an ongoing, continuous, ever-present quest for betterment. With that in mind, we think it’s a good idea to check out these 5 ITIL standards and best practices you can’t live without.

Yep, you read that right, THE fastest. Like the Usain Bolt of check rates, just without the Olympic gold medal to back it up (but it’s safe to say that if there was a gold medal for quickest check rates, we would win gold). So what does this actually mean? It means that your website will be checked almost constantly; every 30 seconds depending on the plan that you pick.
