The Federal Government began on Tuesday (11th) the SUS Sovereign Cloud program. This initiative involves a large transfer of national health data to internally located servers. The administration of these computers will be managed by the State, utilizing Serpro (Federal Data Processing Service), aiming to ensure digital sovereignty in the area.
In addition to ensuring greater accessibility to patient data for health institutions, the measure aims to reduce dependence on foreign technologies. Implementation will occur in distinct phases: the first phase will cover more than 230 million Brazilian and foreign citizens registered in the National Registry of SUS Users (CadSUS). Subsequently, the second stage will focus on the National Health Data Network (RNDS), which covers about 5 billion records. The final plan foresees the consolidation of over 450 integrated applications.
As informed by the Ministry of Health, the experience of Brazilian users accessing SUS digital services will remain unchanged, but with reinforced security guarantees, in compliance with the LGPD, and with data integration at the federal level. Minister Alexandre Padilha announced an initial contribution of R$ 18 million for this first phase, named Foundation, with the goal of completing the CadSUS migration by the end of 2027.
This action is aligned with the concept of digital governance. The government mentioned that nations such as China, Russia, and various European countries are undergoing similar processes, seeking internal control over public services, which are currently fully embedded in the digital environment.
A study conducted in 2025 by the Department of Geography of the Federal University of Paraná (UFPR) had highlighted the risks of keeping sensitive SUS data on foreign company platforms. Currently, the RNDS is hosted on Serpro MultiCloud, an infrastructure that uses services from large technology companies, such as Amazon Web Services (AWS). The proposed migration serves as a strategy to circumvent this technological dependence.
In another context of digital governance, the participation of Brazil in WAICO, the International Organization for Artificial Intelligence Cooperation, stands out. The 29 members of this organization work to find methods that increase the Global South's access to artificial intelligence development. Despite having national AI models, Brazil still depends on LLMs from foreign corporations, notably American ones like Google, OpenAI, and Anthropic, and there is still a long way to go to achieve independence in this sector.
During the event held in Brasília, the Federal Government presented data on the digitalization of SUS. Currently, the SUS Digital application registers more than 70 million downloads, and its professional version already has integration with 84% of municipalities in the country. The unification of this information promises to facilitate access for these professionals. Additionally, the ministry emphasizes the relevance of digitalization for offering services such as telemedicine, which saw growth last year. This service can also benefit from migration to fully national servers, allowing greater agility in cross-referencing data and information about specialized care and support networks.
