Unlock[ed]

Nutanix[ed] is a blog sharing my experiences. I am hopeful it differentiates from the information overload that seems to be shared as there is so much information online; it can be all-consuming and often brings you no additional value. The goal is to share my experience, successes, and failures to help you navigate your journey, inspire you, and, most importantly, provide takeaways that will be useful in your career.  My last blog was all about the hypervisor. I chose to save the discussion on how to free yourself from a hypervisor, its inherent costs, and lock-in. So, now I will…

What’s in a hypervisor?

I came across a technical whitepaper comparing Citrix XenServer and VMware vSphere, the two leading server virtualization platforms back in 2009.

It only took a glance at "Authorizing inbound traffic for your Windows instances" for me to figure out the basics. I then had Linux instances to figure out. That also was straight forward. I had not…

As I work from home more than ever now, it is becoming blatantly evident that there are some processes that I need to get in order. Am I the only one suddenly realizing that my daily activities are scattered all over the place? I mean, my notes are being taken by hand, Apple Notes, GoodNotes, Evernote, and elsewhere. My files are stored locally, in OneDrive, Dropbox, Google Drive, and other various locations.  My unorganized workflow got me to thinking. I have to get this cleaned up, and quickly! What happens if my computer crashes? If I need to recover a…
