In this Episode, we are joined with our colleagues Allen Brokken and Shannon Kuehn on how they leveraged components of Azure to introduce automation for a customer to keep 1000’s of VMs updated regardless of where the infrastructure is running!
This was accomplished using in-built capabilities in Azure called update management and a component called Hybrid runbook workers. This is facilitated by a feature called Azure Automation which you can think of as a server-less script scheduler and execution environment in the cloud. In a nutshell, hybrid workers are machines running anywhere (on-premises, Azure or other clouds) with a specialized agent installed that permits Azure Automation to instruct these targeted machines the ability to perform work within a private/isolated network. Azure Automation can easily target resources within Azure; but should it need to do something such as apply a specific update to a machine within the boundaries of a private datacenter the hybrid worker provides a firewall friendly facility to poll for work to run locally. In this video we walk through how this can all be stitched together to address the simple task of keeping servers up to date at scale!
