What Is Citrix DaaS?
Citrix DaaS is a cloud-managed desktop delivery platform that separates the management plane from your resource locations. Your virtual desktops and applications can run on any combination of on-premises infrastructure, Microsoft Azure, Amazon Web Services (AWS), or Google Cloud Platform (GCP) — all managed through a single, cloud-hosted control plane.
Unlike traditional Virtual Apps and Desktops (CVAD) deployments where you manage every infrastructure component yourself, DaaS shifts the responsibility for the management layer to Citrix Cloud. You retain full control over where your workloads run and how your data is stored, while Citrix handles platform updates, monitoring infrastructure, and service availability.
For South African organisations, this model addresses two persistent challenges: reducing the operational burden of managing virtual desktop infrastructure while maintaining data sovereignty through local Azure regions in Johannesburg and Cape Town.

Key Capabilities
Hybrid and Multi-Cloud Flexibility
Citrix DaaS supports resource locations across on-premises data centres, Azure, AWS, and GCP — simultaneously. Organisations running existing CVAD environments can extend into DaaS incrementally, maintaining their current investments while gaining cloud-managed capabilities. This hybrid approach means you migrate at your own pace, not on a vendor's timeline.
HDX Protocol for Optimal User Experience
The Citrix HDX protocol delivers high-definition desktop and application sessions even over constrained networks. Adaptive transport and EDT (Enlightened Data Transport) protocol automatically adjust to network conditions, providing consistent performance for users in Johannesburg head offices and remote branches alike. HDX ensures that graphics-intensive applications, video conferencing, and unified communications perform reliably across any connection.
Azure South Africa Regions for Data Sovereignty
Running Citrix DaaS on Azure South Africa (Johannesburg and Cape Town regions) keeps your data within the country's borders. This architecture supports POPIA compliance requirements and addresses data residency concerns that prevent many organisations from adopting cloud-hosted desktops. OAS designs and deploys Citrix-on-Azure architectures that optimise for both compliance and performance.
Citrix Aidrien — AI-Powered Administration
Citrix Aidrien, generally available since March 2026, brings AI-assisted administration to DaaS and CVAD environments. Aidrien translates natural-language queries into OData API calls, enabling administrators to troubleshoot session issues, analyse usage patterns, and generate reports without writing complex queries. This reduces mean time to resolution and makes your operations team more effective.
Enterprise Security and Identity
Microsoft Entra single sign-on (SSO) support extends across Workspace app platforms, simplifying authentication for end users. Citrix Gateway Service for StoreFront — now generally available for both DaaS and on-premises CVAD — provides secure remote access without requiring dedicated gateway appliances. Follow-me tagging tracks individual end-user VM usage via hypervisor-level tags, giving administrators granular visibility into resource consumption.
