Your Architecture Has a Cost Personality
Cloud conversations still tend to start in the same place. We talk about scalability, resilience, performance, and maybe security if we are feeling disciplined. Cost usually shows up later (way later), almost like a postscript to the architecture. It is something we validate after the system is live, after usage patterns are real, and after the bill gives us a reason to care. The problem with that sequence is that by the time cost shows up, most of the meaningful decisions ha

GCC Is Not Azure. And That Mix-Up May Cost You Later!
This keeps coming up in real conversations, and it usually surfaces right when decisions start to matter. Someone says they are "in GCC," and from there the assumption creeps in that Azure Government is somehow already in the picture. That leap feels small in the moment, but know it is not. The reference and assumption snowballs into bad architecture, wrong scoping, and uncomfortable conversations when compliance teams start asking harder questions. People are not being carel

Why Your Azure File Sync Migration Doesn’t Look Like On-Premises
There's a very specific moment in almost every Azure File Sync conversation where things go from "this is going great" to "wait, what do you mean we can't do that?" P.S. That happened this week and it took me back, hence the blog post. This usually happens right after the POC looks successful. You've synced a few hundred gigs from the D: drive of an on-premises file server, cloud tiering is working, ACLs look intact, and everyone feels good. Then someone asks how you expose

When Git blocks your push and you know you’re right
There is a special kind of annoyance that only Git seems capable of producing. You clean up a repo locally, get rid of the files you do not want, maybe tighten up the structure a bit so it actually looks like something worth keeping, and then you go to push it up to GitHub expecting a normal, uneventful success. Instead, Git throws a fit and tells you the remote contains work you do not have locally. Suddenly this simple little task turns into a standoff, and Git is acting li

Lost Your SSH Key to an Azure VM? Don’t Panic. Here’s the Fix.
Check it...all code referenced in this blog is for you to peruse here ! There is a moment that almost every cloud engineer eventually experiences. You sit down at a new computer, try to SSH into a VM you built months ago, and realize something uncomfortable. The SSH key you originally used to create that machine is nowhere to be found. Maybe it lived on a laptop that was replaced. Maybe it was tucked away in a .ssh folder that never got backed up. Maybe it was generated autom

RC4 in Kerberos: The Cipher That Wouldn’t Die (Until Now)
Like with previous blogs, all code can be found here ! A fully usable PowerShell module to help you hunt! If you’ve spent any meaningful time working with Active Directory, you’ve probably heard the refrain: “Just disable RC4.” It has been de facto security advice floating around for well over a decade. Most of us nodded when we first heard it, assumed someone in the security team took care of it during the last domain functional level upgrade, and moved on to the next operat
