Clalit Health Services Experts Help Healthcare Company Optimize Architecture to Unite 1,300 Clinics

“We’ve been able to switch to a more proactive way of working…. We’re no longer engaged in ‘putting out fires.’ Instead we work in a way that’s much more positive, efficient, and economical.”
Moshe Belker, WIN System Team Leader, Clalit Health Services

Business Needs

More than 3.8 million people depend on Clalit Health Services for vital services and care in Israel. The substantial scope of its care facilities—14 hospitals, 1,300 community clinics, and 54 x-ray institutes—involves a complex network of varying computer platforms and almost 1,000 separate applications.

Clalit Health Services recently executed an extensive project to connect its 1,300 clinics throughout Israel to a single central database, using its already in-place Active Directory® directory service. The project necessitated precise and meticulous architecture planning to ensure efficiency and optimal performance.

“We needed to conduct a design review to ensure that the Active Directory infrastructure was stable and prepared for such a drastic change,” recounts Moshe Belker, the WIN System Team Leader at Clalit Health Services.


After an in-depth investigation, Clalit Health Services chose to take advantage of the extensive knowledge Microsoft had at its disposal, including experience with similar projects.

“We decided not to reinvent the wheel. The overhead associated with training an internal team to conduct the same infrastructure check would have been prohibitively expensive—and lengthy,” states Belker.

The Microsoft® Active Directory Risk Assessment Program (ADRAP) provided Clalit Health Services information workers with critical insights into the condition of the company’s Active Directory infrastructure. During the in-house visit, a Microsoft engineer and a software architect verified that the company’s existing Active Directory was optimally synchronized and diagnosed.  They then provided solutions for potential issues and created a roadmap for future endeavors.

“The Active Directory health check has been designed to examine whether the Microsoft products you’ve purchased and deployed are working properly and safely—and you’re exploiting the product’s complete capabilities,” says Ran Landsberg, Senior
Technical Account Manager at Microsoft Israel.

Adds Belker, “The visit by Microsoft experts created a safe work environment. It’s like taking a car to a master mechanic for a thorough check. Afterward, you know you can put your mind at ease.”


The ADRAP service helped enable Clalit Health Services to seamlessly connect 1,300 clinics—and 26,000 computers—through a single domain. But the benefits were more far-reaching than Clalit Health Services had anticipated. In addition to supporting the server consolidation, ADRAP increased the company’s wherewithal to work more effectively day-to-day within Active Directory.

Peak Operational Efficiency

The ADRAP session empowered Clalit Health Services to exceed performance goals for Active Directory. During the course of the ADRAP, Microsoft scouted out issues within operations, configuration, and architecture to improve the efficiency of Active Directory.

“Instead of simply telling us the symptoms—we knew those already—Microsoft was able to diagnose the cause of our frustrations. We now know, for instance, whether replication was actually executed, whether everything is properly protected, and if all systems are synchronized. This information creates a very stable system; our uptime has been greatly improved,” says Belker. 

A Proactive—not Reactive—Approach

“We’ve been able to switch to a more proactive way of working. Possible problems are being dealt with long before they actually happen. We’re no longer engaged in ‘putting out fires.’ Instead, we work in a way that’s much more positive, efficient, and economical,” states Belker.

The ADRAP process exposed vulnerabilities in the Active Directory infrastructure and operational processes—before they had an impact on Clalit Health Services customers and employees. And, because of the knowledge gained from the process, the company’s technology team is now able to resolve concerns before they become actual problems.

Performance Stability

As part of the ADRAP engagement, the Microsoft representatives installed the Active Directory Snapshot Tool on the Clalit Health Services system. The company’s internal technology team is now able to analyze performance, as well as pinpoint new vulnerabilities.

“Our system is very stable. The snapshot tool is running in the background, reporting every problem and enabling immediate repairs,” states Belker. “My team is empowered to preserve system stability and availability in the future.”
