Infrastructure in a Nutshell
If you've read my previous article detailing the architecture and technical stack I chose to deploy OpenClaw, today we're getting practical! I'm going to show you, step by step, how to deploy your own instance on a freshly installed Ubuntu virtual machine.
I wondered how I could connect artificial intelligence closer to my VMs. With this in mind, I got my hands on OpenClaw. Honestly, it was a bit of an obstacle course at the start.
With the future (and inevitable) blocking of SSH access on Prism Element and Prism Central, I had no choice: I had to seriously start learning the APIs...
I often get questions about this: how do you assign a physical graphics card to a VM in a simple and performant way? Today, I suggest we look together at how to deploy an NVIDIA Tesla P4 GPU on an Ubuntu Server 24.04 VM hosted on Nutanix AHV, using "Passthrough" mode.
AI-assisted coding, for a complete novice in development like me, is a revolution. It allows me to turn ideas into reality in a few hours where it would have been impossible before. Here's my honest feedback.
I will never forget the day the reality of hyperconvergence hit me. We were in the middle of an infrastructure migration. On one side, we had two full 42U racks from the 3-tier era, packed with servers and storage arrays. On the other side, to replace them, we only needed... 6U.
I've seen too many "cowboys" pull the plug or perform a brutal "Shutdown" via IPMI, thinking data resiliency would handle the rest. Spoiler alert: this often ends with Level 3 Nutanix support. This guide is my lifeline to ensure my cluster restarts without issues.
In this feedback report, I’ll share my experience with Nutanix Centreon monitoring and explain why you should stop monitoring your cluster solely through its Virtual IP (VIP) and switch to a granular node-by-node strategy.
While Hyperconvergence (HCI) and Public Cloud seem to be the norm today, it is crucial to understand that 3-Tier was the backbone of enterprise IT for nearly 20 years. To understand this architecture is to understand where we come from, and why we sought to change it.
