Microsoft cloud operating system platform is named or at least codenamed as “Windows Strata” Microsoft is indirectly confirming the name on its Professional Developers Conference (PDC) Web site, where all of its cloud-related sessions are now lumped under the “Windows Strata” heading. Is Strata the product currently codenamed “Red Dog”? I’m not sure. But I think Strata might be the Red Dog plus a layer of cloud infrastructure services (like management, virtualization, networking, storage, etc.).
