Moving a Windows environment to the cloud - DevOps Galway Meetup
Download as PPTX, PDF1 like171 views
This document provides an overview of moving a Windows environment to the cloud. It discusses initial considerations like infrastructure as a code (IaaS) and automation pillars for provisioning, configuration, and deployment. It also covers specific Azure technologies and considerations for subscriptions, resource groups, regions, and other unique aspects. Tips are provided for storage, bootstrapping, key vaults, Terraform, Desired State Configuration (DSC), and Azure DevOps Pipelines.
