# Sustainable and Reliable Information and Communication Technology for Resilient Smart Cities
## 8 Towards Reliable Information and Communication Technology for Resilient Smart Cities  
This section summarizes our key findings for a viable path towards the establishment of reliable and trustworthy urban ICT for sustainable smart cities across Europe and the globe in the coming decades. We structure the recommendations in four categories (see Table 4) relating to oupPLUS and present calls for action based on the current state of play. The target group for our recommendations is constituted by IT decision makers at city/community level. This includes Chief Digital Officers (CDO) and IT architects of relevant municipal/utility companies in addition to people responsible for tender definition and strategy development towards the establishment of resilient and sustainable ICT-based smart cities. The so defined target group outlines a clear profile of stakeholders within a city development team that take a role between official city representatives, who are normally not familiar with IT terminology, and the core IT technological teams (e.g., within a subcontractor), which on the contrary do not need to be familiar with the final receivers of the provided ICT services.
