Atos launches EU-designed Sovereign Cloud platform for government and critical infrastructure modernisation

Atos has launched Atos Sovereign Cloud, a next-generation application platform designed for governments, defence organisations, healthcare providers, and critical infrastructure operators. The cloud service combines enterprise capabilities with sovereign controls for data management, operational independence, and cyber resilience. Designed and engineered in the EU, the platform addresses growing demand for sovereign IT services amid stricter regional regulations. Gartner predicts over 50% of multinational organisations will have digital sovereign strategies by 2029, up from less than 10% today. The platform leverages Atos' expertise in cloud transformation, cybersecurity, and AI infrastructure. It enables organisations to modernise mission-critical applications whilst maintaining control over data, operations, and IT supply chains. The service forms part of Atos Group's integrated digital sovereignty strategy.

Viasat partners with Atos on digital workplace modernisation amid execution concerns

Viasat has announced a multi-year partnership with Atos to modernise its global digital workplace, including service desk, advanced support and intelligent collaboration tools across worldwide operations. The initiative focuses on internal technology and process upgrades aimed at improving operational efficiency and customer service delivery. The partnership represents an incremental development in Viasat's investment narrative, though it doesn't materially change the near-term focus on ViaSat 3 execution and key risks around high capital expenditure and free cash flow pressure. More significant for investors is the recent addition of Shekar Ayyar and Jinhy Yoon to the Board and Strategic Review Committee, which directly affects governance and oversight of major programmes. Viasat's narrative projects $5.1 billion revenue and $557.4 million earnings by 2029, though analyst opinions vary widely on the company's prospects.

Airbus rents $112M HPC supercomputer from Bull over 5 years

Airbus has inaugurated a new supercomputer from Bull, delivering three times the performance of its previous system under a €100 million five-year HPC-as-a-service contract. Bull won the deal from previous supplier HPE after 24 years. The system, based on Bull's BullSequana XH3000 infrastructure, uses AMD Epyc processors, Nvidia GPU blades, IBM Spectrum Scale storage and Nvidia InfiniBand NDR interconnect. Hardware is spread across sites in Toulouse and Hamburg but functions as a single supercomputer. Airbus will use the system to develop future aircraft through digital twins, simulating entire airframes alongside design work. The company is likely using CODA computational fluid dynamics software, developed jointly with German and French aerospace laboratories. Bull is also working with Airbus on quantum and AI algorithms.
