4.1 Hybrid Strategy

The IT of the City of Vienna follows a hybrid strategy that combines Opens Source and licensed solutions. Decisions are based on comprehensive Total Cost of Ownership (TCO) analyses, ensuring technological independence and security. Key focus areas include the expansion of API (Application Programming Interfaces) management as a further development of open data initiatives, and the consistent use of on-premises and cloud infrastructure. With Infrastructure as Code (IaC), applications are intended to be made “mobile”, allowing them to be shifted between the data center and cloud providers – ensuring that the City of Vienna’s IT remains future-proof and efficient.
