Marco Schilder · independent IT consultant and architect

Clarity
between Clouds

I design Microsoft cloud environments, lead the migrations towards them, and make sure identity and certificates still hold up afterwards. Twenty-five years in IT, and a habit of explaining complicated technology to the people who have to live with it.

Worked for, among others

What I get brought in for

Usually by organisations moving to the cloud who discover halfway through that the environment has outgrown its documentation.

Cloud design and architecture

Azure, Microsoft 365 and Modern Workplace. High Level and Low Level Designs, baseline blueprints, and infrastructure as code with Terraform and Azure DevOps. Designs a team can actually execute, not just read.

Migrations and transitions

From on-premises datacentre to private or public cloud, cross-forest Active Directory, Exchange, file servers and virtual machines. Runbook, execution and aftercare — including the systems nobody wants to touch.

Identity, PKI and security

Active Directory, Entra ID, Entra Connect, ADFS and federation. Public Key Infrastructure and Certificate Lifecycle Management: from issuance architecture to the management process that stops anything expiring unexpectedly.

Advice and handover

Workshops, assessments and plans of approach. I approach technology from the user's point of view and deliver the documentation your organisation needs to take it over.

Engagements

Twenty-five years in IT, independent since 2023. A selection of recent work.
