Introduction to Azure Automation

Deploying and maintaining the desired state to servers and application is one of the hardest parts for IT Pros and Infrastructure Engineers, further it can be an error prone. Azure Automation Desired State Configuration (DSC), we can consistently deploy, reliably monitor, and automatically update the desired state of our It infrastructure at scale from the cloud. It build based on the PowerShell DSC, Automation DSC can configure machine configuration with a specific state in physical and virtual machines (VMs), using Windows or Linux, and in the cloud, on-premises or other cloud vendors . By Azure Automation we can deliver application with consistent control and manage rapid change across your heterogeneous hybrid IT environment with easy control.

Key Advantages of using Azure Automation DSC

  • Simplify administrative tasks by configuring one or more resources automatically.
  • Configure servers identically for standardization to reduce support cost.
  • Remediate unauthorized changers to prevent configuration drift.
  • Simple and automated deployment on demand for private,public or hybrid cloud.
