A Custom Federated Identity Management System with Microsoft Azure

Terrace designs and develops a custom Federated Identity Authentication System for Varian Medical Systems.

Before releasing Varian Medical System’s new generation oncology patient management system and the very first comprehensive software platform for coordinating cancer care, Varian needed to optimize their previously used secure user authentication system.

The new system would need to ensure 1) the secure identity management and verification properties of Varian’s proprietary system and 2) a seamless flow of tokenized information between Varian’s systems and databases and all other user and third-party provider systems and devices.

With their legacy software in hospitals worldwide, they needed a robust system to protect all user information, including all patients’ personal health care information (PHI data) shared on the system.

Varian had considered other consultants, but once connected with Terrace, Gunther Lenz, Director of OCS Technology Office at Varian noted, “We were impressed with the knowledge Terrace showed even in that first design session. It became
very apparent that it would be a huge help to get their expertise to help our journey towards Azure or with technical problems.”

The Terrace Process

Terrace + Varian

The Microsoft Azure team introduced Varian to Terrace. Varian selected Terrace during their first architecture and design session, feeling most comfortable with Terrace’s expertise and ability to design a solution.

  • Varian wanted to leverage the flexible, authentication mechanisms of customer systems, like Active Directory, with that of their own proprietary system. The Varian team wanted a New World Integration System. Terrace would need
    to make sure authentication flowed nicely between the different components in the system and that it was “future proof” to upcoming features from Microsoft.
  • The Federated Authentication System would be an integral part of 360 Oncology, designed to bring the data of patients to the places needed at the time needed. It would be accessed from the web and mobile networks across the globe
    and would be the first thing users would experience in logging in. So access to patient care information would need to be efficient and convenient.
  • Terrace designed a system that would ensure a smooth, seamless customer experience from the first moment they logged in, whether they accessed the system from EMRs (electronic medical records) or from other health care systems.

The Results

The Federated Identity Authentication System is an integral piece of the system. Terrace helped Varian create a smooth experience between the systems.

“This is a product for customers. All Terrace’s work may not be visible.  All the complexities are taken care of in the back end. The advantage for the customer is if they have a health information system, another EMR, or any other
system, we can seamlessly integrate that with the same authentication mechanism they are already using. That is really the benefit! For the customers, it’s all behind the scenes. They just know that suddenly everything works together
nicely with just one login. That is the cool part.”
