Infrastructure consultant argues strong architecture depends on hands-on production experience

An infrastructure consultant writes about years of advising financial, logistics, and healthcare organizations on turning architectural diagrams into systems that run in real operating conditions. The author describes early work managing Microsoft Exchange, mailbox migrations, and Active Directory in the financial sector. Later roles covered hybrid cloud design, identity management with Microsoft Entra ID and MFA, endpoint management with Intune and SCCM, and HIPAA-compliant AWS systems in healthcare. The piece argues that architects who have operated systems hands-on are better placed to design architectures that survive production, and it ends by emphasizing designing from operational reality rather than from the whiteboard.
