Workload Specific Suggestions*

Application Recovery with PowerShell Desired State Configuration

Hemant Mahawar, Senior Program ManagerWindows PowerShell

Reconfiguration is tedious and error-proneSubnet, IP, firewall rules, DNS, permissions, share/resource access, Capacity availability

Contributes to higher RTO

Current solutions are expensive and do not scale in a cloud era

DR is the biggest configuration change for an Application

Future beckons us with…..

….. PowerShell Desired State Configuration

PowerShell Progression …

Life in the Cloud bigger scale and faster cadence

Scale * Complexity >> Skills Change is Primary cause of outage

Rapid change, at scale with, constant failures

DSC scales, simplifies complexity and can auto-correct

Why Desired State Configuration

DSC Decouples …

Configuration Management Platform for Windows

Simplify configuration

Enable continuous deployment

Prevent configuration drift

PowerShell Desired State Configuration

Deterministic, automated re-configuration of Application post failover

Recovery configuration should be identical to primary

Recovery side environment should be captured in a Recovery side Environment File

Recovery Configuration Requirements

Demo:DSC with Azure Site Recovery

Deterministic, automated re-configuration of Application post failover

MOF file provides documented evidence of what change got applied

Scales with Cloud deployments while keeping RTO low

We are just getting started. As DSC adoption grows, ASR will be there to leverage it
