Karthik Iyer is Sirius Star's senior cloud architect. He spent 10 years deep in the Microsoft stack as a partner consultant (Azure, Microsoft 365, Entra ID, Dynamics 365, Power Platform, Sentinel) before adding four years of AWS work for Indian mid-market customers running hybrid workloads. His bias is anti-hype. He'll tell a Microsoft-anchored buyer to consider Zoho where it fits, push back on AWS region defaults that ignore Indian data-residency, and explain when a customer is paying for licences they don't use. Karthik writes on cloud architecture, productivity stack decisions, vendor lock-in, and the messy reality of running Microsoft and Google Workspace side-by-side. Based in Navi Mumbai with a strong opinion that the best cloud strategy is the one your team can actually run on a Tuesday afternoon. Black coffee, no sugar.
