Design Decision: Cost Optimization

How can I use Citrix Autoscale for both on-premises and cloud workloads?

  • Use cloud workloads for burst capacity or for business continuity by tagging cloud workloads in the delivery group. Set Autoscale to power manage these tagged workloads. Use the selective power management feature to set the zone preference and failover to prefer on-premises workloads.

  • Use the dynamic provisioning feature of Autoscale with low and high watermark machine counts. This approach reduces costs and still support demand under high loads. This feature is especially useful for instance types with high monthly charges.

  • If usage and capacity patterns can be predicted on a consistent basis, use the schedule-based scaling feature to manage available capacity. Configure the settings to start within a 30-minute window. When paired with the capacity buffer, the scheduler prevents users from waiting for capacity to come online.

  • When enabling Autoscale, prefer smaller instances over larger instances. Smaller instances drain faster and go offline sooner.

Should I use Windows 10 Multisession or Windows Server OS?

  • Windows 10 Multisession has about 10% lower densities than the Windows Server operating systems

  • Windows 10 Multisession allows users access to the Windows Store, which is not available on the server operating systems

  • Azure Virtual Desktop (AVD) entitlement grants you the base VM price (Linux Pricing), saving a considerable amount over the normal Windows VM price
