Founded in 1958, Taipei VGH is a national medical center in Taiwan with responsibilities spanning patient care, clinical training and medical research. It operates at a significant scale, with nearly 10,000 employees, 3,136 beds and 68 operating rooms, while serving roughly 8,000 outpatient visits per day.
As an early adopter of hospital IT in Taiwan, Taipei VGH began mainframe system development in 1978 and completed a major shift to open systems by 2020. The hospital’s IT roadmap now supports a new wave of AI- and data-driven initiatives that require faster change, stronger stability and tighter security controls than its prior platform could deliver.
At-a-Glance
Taipei Veterans General Hospital (Taipei VGH) modernized its legacy Java-centric application platform with SUSE Rancher Prime to support more flexible development, stronger resilience and a security posture better suited to data-driven healthcare. Alongside building an AI-ready foundation, the SUSE solution reduced application recovery time by over 95%, from 10–30 minutes to three to five seconds improving the experience for busy hospital staff.
Overcoming limits of a shared Java runtime and platform-wide outages
Taipei VGH’s legacy Java application server model required all systems to run on the same Java runtime environment (JRE) version. That constraint limited development teams’ ability to adopt newer Java technologies, because newer versions often did not match the platform’s baseline JRE. When the application server required upgrades, teams also had to update and revalidate code across systems, which increased effort and slowed delivery.
The legacy architecture also increased operational risk. A failure in one application could destabilize the entire platform on a host, affecting multiple systems at once. Recoveries required full restarts that typically took up to 30 minutes, an unacceptable disruption window for clinical services that depend on consistent access to applications.
Finally, the legacy stack struggled to support non-Java development. Taipei VGH could not easily run Python, C# or PHP workloads, which constrained AI application plans and reduced flexibility for outsourced development models.
"Thanks to SUSE Rancher Prime, application failures that previously required 10–30 minutes to recover can now be resolved by restarting a single container in just three to five seconds — a change that frontline medical staff barely notice."

Why SUSE Rancher Prime?
In 2022, Taipei VGH evaluated leading container platforms and chose SUSE Rancher Prime for its open source flexibility with the stability and commercial support expected in healthcare. The hospital sought a platform to reduce the operational burden associated with running upstream Kubernetes alone, while still giving teams a scalable foundation for modernization.
Taipei VGH selected SUSE Rancher Prime based on three decision factors: strong support, cost-effectiveness and access to technical assistance through its local services partner, WebComm Technology. Together, those criteria aligned with the hospital’s need for predictable operations and a manageable path to expanding container adoption across many application teams.
The impact of SUSE Rancher Prime
Taipei Veterans General Hospital has made steady progress moving Java applications onto its container platform. Thus far, the hospital has migrated 72 of 109 targeted application projects, 66% of the current scope, giving more teams a consistent foundation to modernize services while reducing reliance on the legacy application server model.
Reduces application recovery time by more than 95%
With SUSE Rancher Prime, Taipei VGH moved away from platform-wide restarts when an application fails. Teams now restart only the affected container, restoring service in three to five seconds instead of up to 30 minutes, which is more than 95% faster. That change improves continuity for frontline clinical staff, who see minimal disruption during recovery events.
Improves development flexibility with independent runtime environments
SUSE Rancher Prime improves development agility by allowing each project to run in an independent runtime environment rather than forcing all systems onto a single JRE version. Taipei VGH also increased consistency between development and production environments, which supports faster development cycles and smoother releases.
Builds a foundation for AI-ready development and stronger security practices
By supporting a broader range of languages such as Python, C# and PHP, SUSE Rancher Prime helped Taipei VGH remove a barrier to future AI applications and create more options for outsourcing work when needed. The container model also makes it easier to upgrade to newer, more secure runtime versions, reducing exposure when older runtimes stop receiving security updates.
In addition, SUSE Rancher Prime’s automatic scaling helps the hospital maintain stable service under high-concurrency demand, which supports the operational consistency expected from clinical systems.
What’s next for Taipei Veterans General Hospital?
Taipei VGH plans to deepen its modernization work in three areas. First, the hospital aims to refactor shared capabilities, such as billing and queue management, into microservices, trusting some of their most sensitive workloads and migrating them with confidence into SUSE Rancher Prime. Second, the hospital plans to strengthen container security by adopting SUSE Security to improve east–west protections in container environments. Lastly, the hospital intends to adjust licensing and deployment strategies based on resource usage as it expands the platform’s capacity for additional projects.
