Hydra vs Parallels Remote Application Server (RAS)

Hydra provides a management layer for Azure Virtual Desktop and Windows 365 environments. For AVD, it can scale capacity and manage power according to usage, helping reduce idle compute costs; image lifecycle management includes one-click rollback. An optional Hydra Agent measures session-host performance and shows user processes on a session or host. Documented integrations include FSLogix, Hybrid Active Directory, Microsoft Entra and Intune. Hydra can be deployed from the Azure Marketplace into an Azure resource group and accessed through a web portal. It can use a least-privilege Azure service principal, with activity auditable through Azure Activity Logs and Microsoft Graph. Tenant isolation uses Azure RBAC boundaries and tenant-specific credentials. The free Community Edition has limited tenants and host pools. Hydra for Windows 365 is listed at $1 a month, and Hydra for AVD at $5 a month, both billed month-to-month. Login VSI states that it is ISO 27001 certified and GDPR compliant.
