The Architecture Board Loves Approving New Systems. It Almost Never Retires the Old Ones.

August 7, 2026 by Ryan Horst

Ask anyone on your architecture board to name the last system the board actually voted to retire, not deprecate in a slide, not flagged "legacy" in a spreadsheet somewhere, but formally decommissioned. Watch them pause. They'll rattle off every platform evaluation and integration exception from the last year without breaking a sweat, but retirement almost never shows up as its own agenda item. It shows up as a footnote buried in someone else's proposal, if it shows up at all. That's not because … [Read more...]

Architecture Principles Don’t Score an RFP. Implications Do.

August 5, 2026 by Ryan Horst

low angle photography of architecture building

Ten principles on a slide, a paragraph of rationale under each, reviewed by the board twice a year and opened by nobody else in between. That's how most architecture principles documents live out their existence. Then a $2M platform RFP goes out the door, gets scored on cost, feature checklist, and vendor references, and the principles document never enters the room. Nobody decided it didn't matter, and that's kind of the point, nobody did the work required to make it matter to an evaluator … [Read more...]

Architecture Decision Records Are a Governance Control, Not a Documentation Habit

August 3, 2026 by Ryan Horst

a black and white photo of a bridge over water

Someone challenges your team right now to produce the reasoning behind last quarter's biggest architecture call, not the decision itself, the actual reasoning, and I want you to be honest with yourself about how long that would take. For most EA boards, the honest answer is "we'd have to ask around and hope the right person still works here." That gap is where a familiar meeting keeps happening: someone proposes a change, a senior architect objects that "we already decided against this," and … [Read more...]

Why I Standardized on LeanIX as the EAM System of Record

Why I Standardized on LeanIX as the EAM System of Record

A director on our ARB asked a simple question last quarter: how many identity providers are we running in production, right now, today. Three architects in the room gave three different numbers, and none of them matched the CMDB export somebody pulled up on the spot to settle it. The meeting stalled for ten minutes while people argued over whose spreadsheet was current (mine wasn't, for what it's worth). That's not a staffing problem, and it's not a communication problem either. That's what … [Read more...]

The Architecture Review Board: Narrow Docket, Small Room, Hard Exceptions

July 31, 2026 by Ryan Horst

A blueprint of a building with a bunch of windows

A board that reviews everything ends up governing nothing. I've sat through review meetings that burned a full hour on one team's API contract, argued clause by clause, while the actual risk in the portfolio sat three agenda items down, untouched, ticking. The fix isn't more rigor in the room. It's a shorter, sharper definition of what the room is actually for. I hold one of these seats myself, and I take the calendar invite seriously enough that it changes how I spend the rest of my week. The … [Read more...]

Reuse, Buy, Build: The Order Most Companies Get Backwards

July 30, 2026 by Ryan Horst

Thirty-five percent of enterprises have already replaced at least one SaaS tool with something built in-house, and sixty percent of those builds happened as shadow IT, outside procurement and outside architecture review, according to Retool's 2026 Build vs. Buy Report. That second number is the one that should keep an EA board up at night, not the first. A tool getting replaced is just the market doing its job. A tool getting replaced by something nobody on the architecture side ever laid eyes … [Read more...]

Ivory Tower vs. Distributed EA: The Federated Model Wins, But Only With Teeth

April 28, 2026 by Ryan Horst

a close up of a building made of concrete

My take is federated with some teeth. I've run architecture both ways, and now I sit on an EA board that has to answer this question with actual budget and actual risk attached to it, not as some abstract debate you have over coffee. A pure central-authority model doesn't survive a modern delivery cadence, full stop. A pure distributed model quietly gives up the consistency that security, compliance, and cost control all depend on, and it does it fast. The fix isn't a philosophy. It's a short … [Read more...]

I Am Back For Round 2

January 15, 2026 by ryanhorst

New year, and I'm making myself an actual resolution instead of a vague one: write more, share more of what I'm actually seeing and thinking about. It's been a while since I posted here, so consider this the restart. Somewhere in the gap between my last post and this one, I had kids. Then more kids. I'm now outnumbered by four boys, all under ten, which is exactly as loud and chaotic as it sounds and I wouldn't trade it. Somewhere in that same stretch I moved from hands-on cybersecurity work … [Read more...]

FireEye Dashboards Replicated In Splunk

August 21, 2014 by ryanhorst Leave a Comment

My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. After installing the FireEye app for Spunk and having some issues with it, the app was uninstalled, which left a gap that needed to be filled. So off I went into Splunk land to see if I could scrounge together some decent "dashboard" worthy search queries that could help display important information. Below are a collection of the search queries I have built thus far. It … [Read more...]

FireEye Role Based Access Control (RBAC)

April 16, 2014 by ryanhorst 7 Comments

My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. Regarding role based access control and Active Directory integration with FireEye back in FEOS versions 7.0.x (webmps), 6.3.2 (emailmps) and 6.4.1 (CMS), we only had the ability to map a single Active Directory group to a single FireEye "role". And most enterprises would probably have mapped that single group to the Admin role. Well..... Fast >> Forward >> … [Read more...]
