Why Citrix Is the Best Platform to Host Siemens Varian ARIA — from Small Clinics to Large Health Systems
Organizations running Siemens Healthineers Varian ARIA or ARIA Core often ask us the same question: “We only have 10 or 12 ARIA users. Do we really need Citrix?”
It’s a fair question, especially for smaller oncology clinics and local healthcare providers. But it’s also a question that comes up in much larger organizations that already rely on Citrix for hundreds or even thousands of users.
Based on our experience supporting Siemens Varian ARIA environments across the United States and Canada, the answer is consistent: Citrix is the best platform to host Siemens Varian ARIA — not only for large health systems, but also for small environments with fewer than 15 users.
The same architectural principles that make Citrix the standard for large ARIA deployments also apply to smaller ones.
Citrix is widely used to host large Siemens Varian ARIA environments, including:
In these organizations, Citrix is not chosen for convenience. It is chosen because it delivers predictable behavior, strong isolation, and longterm stability at scale.
What matters is that ARIA behaves the same way on Citrix whether there are 10, 50 or 500 users. The architecture does not change — only the scale does. This is why the reasoning behind using Citrix for small ARIA environments remains valid, and in many cases even more important.
ARIA supports oncology workflows, treatment coordination, and access to highly sensitive patient data. Performance issues, session instability, or inconsistent behavior are not just IT problems — they directly affect clinical operations.
Citrix, managed by Altanora, has long been used in healthcare precisely because it provides:
These characteristics align well with the operational expectations of Siemens Varian ARIA environments.
A common misconception is that fewer users mean lower risk. In practice, small ARIA environments are often more sensitive to disruptions.
Smaller clinics typically have:
In a 10 or 15 user ARIA deployment, one unstable session can disrupt an entire care team. Citrix reduces this risk by providing strong session isolation and controlled application behavior, even during long clinical sessions or under imperfect network conditions.
One of the oftenoverlooked benefits of Citrix is how much it simplifies support and longterm operations when deployed correctly.
Citrix enables:
For support teams, this means:
This is a key reason Citrix remains a trusted platform in healthcare environments where uptime and reliability are critical.
Generic VDI, basic RDP, or cloud desktops are often designed for office productivity workloads. They may appear easier to deploy, but they typically lack the controls and predictability required for clinical systems like ARIA.
Citrix provides capabilities that are particularly relevant for ARIA:
For both small clinics and large health systems, these characteristics translate into fewer disruptions and more consistent clinical workflows.
When evaluating how to host Siemens Healthineers Varian ARIA, organizations often compare Citrix with Omnissa Horizon (formerly VMware Horizon), Azure Virtual Desktop (AVD), Windows 365, or even traditional PCs. While each option has valid use cases, they are not equivalent for clinical oncology workloads.
Citrix is better suited for ARIA because it was designed for applicationcentric, longrunning, stateful workloads that must remain stable over time.
l workloads that must remain stable over time.
For Siemens Varian ARIA, the goal is not just access — it is predictable, supportable clinical operations. Citrix is designed for exactly that.
Citrix is powerful but operating it correctly requires expertise. This is where Altanora and its partner ecosystem play a critical role.
Altanora does not operate in isolation. We work closely with a network of trusted partners who support local health systems, clinics, and healthcare providers across the US and Canada.
Together, we deliver Citrix as a fully managed, pay-per-user, hosted service, designed specifically for regulated healthcare workloads such as Siemens Varian ARIA.

These capabilities are delivered as a unified, managed service, reducing complexity while increasing security and operational consistency.
Altanora Secure DaaS+ is not limited to a single hosting model. The platform is designed to adapt to the operational, regulatory, and clinical realities of healthcare organizations.
Secure DaaS+ can be:
Regardless of the deployment model, the same Citrixbased architecture, security controls, and operational practices apply. This ensures consistency, portability, and longterm stability as organizations evolve.
Citrix is undeniably enterprise technology. It is used by large health systems, supports thousands of users, and powers missioncritical clinical platforms like Siemens Varian ARIA.
What Altanora changes is how that enterprise technology is consumed.
Through Secure DaaS+ and a partnerled delivery model, Altanora removes architectural and operational complexity while preserving the robustness of Citrix. Healthcare organizations get enterprisegrade reliability, security, and scalability — without needing to operate enterprisegrade complexity internally.
This makes Citrix agile, accessible, and practical for both small clinics and large health systems.
Citrix is sometimes perceived as expensive. In reality, cost is driven far more by how the platform is operated than by the technology itself. By delivering Citrix through Altanora and our healthcare partner ecosystem:
This approach lowers total cost of ownership without compromising reliability or safety — a critical balance for healthcare organizations.
Whether you are supporting:
The same principles apply: stability, supportability, and security matter more than simplicity on paper. Citrix provides that foundation. Altanora and its partners make it practical, manageable, and costeffective.
Citrix remains the best platform to host Siemens Healthineers Varian ARIA, from small clinics to large, complex health systems. When delivered through Altanora Secure DaaS+, Citrix becomes simpler to operate, easier to support, and more economically sustainable — while preserving the stability and reliability that clinical environments demand.
