Why thermal management is emerging as a strategic enabler

AI is transforming how we compute, but it is also exposing a critical infrastructure challenge: how do we cool increasingly powerful compute environments? For decades, air cooling has been the foundation of data centre design. It is proven, familiar, and effective for traditional enterprise workloads. However, the demands of AI are fundamentally different. Large-scale AI training, high-performance computing, and dense GPU deployments are driving power densities to levels that push the practical limits of air cooling. Whilst average rack densities have historically ranged from 10 to 20kW, the industry is rapidly moving towards deployments measured in hundreds of kilowatts per rack, with discussions of 600kW and even 1MW architecture becoming more common. This shift is forcing data centre operators to rethink how infrastructure is designed, powered, and cooled. Innovative technologies such as immersion cooling are becoming part of that conversation, not simply as a way to remove heat, but as an enabler of higher compute density, improved efficiency, and scalable AI infrastructure. In the AI era, cooling is no longer just a facilities consideration; rather, it is a strategic infrastructure decision that will help determine how far and how fast organisations can scale the next generation of computing.

Multiverse Computing, YellowDog target European sovereign AI

Multiverse Computing, a Spanish company specialising in compressing large language models (LLMs), and UK cloud workload orchestration firm YellowDog.ai have agreed to work together to improve compute efficiency and support the development and deployment of European sovereign AI. The collaboration will combine AI model compression with hybrid and multi-cloud compute management to help enterprises, research organisations, and public sector institutions operate AI within European infrastructure. Multiverse Computing’s CompactifAI technology uses quantum-inspired tensor-network methods to compress large AI models, while YellowDog.ai provides a platform for managing compute resources across hybrid and multi-cloud environments. The companies say they aim to bring together processing capacity, secure access, storage, networking, and data centre operations, whilst simultaneously reducing costs, energy consumption, and infrastructure complexity. They also identify GPU shortages as a key challenge, particularly for European organisations seeking to make more efficient use of available capacity. Customers will be able to use the combined capabilities for model development, benchmarking, optimisation, compressed model deployment, inference, and sovereign infrastructure planning. Target sectors include financial services, life sciences, advanced engineering, energy, telecoms, public services, and defence-adjacent industries, where data residency, security, cost, compute availability, and regulatory compliance are important considerations. Supporting Europe's AI compute infrastructure Enrique Lizaso, co-founder and CEO of Multiverse Computing, says, “Sovereign AI will only succeed if it is economically and technically sustainable. Our compressed AI models are designed to run faster, use less energy, and operate closer to the data. "Working with YellowDog.ai gives customers a powerful route to deploy efficient AI across cloud, on-premises, edge, and sovereign data centre environments.” Bruce Beckloff, CEO of YellowDog.ai, adds, “Europe has the talent, data, and industrial base to lead in AI, but it needs infrastructure that is fast, efficient, secure, and sovereign by design. “By partnering with Multiverse Computing, we are creating practical capacity solutions where organisations can scale compute intelligently, reduce bottlenecks, and retain control of critical workloads.” The agreement comes as European organisations seek alternatives to fragmented, expensive, and capacity-constrained AI infrastructure. The companies also point to the European Commission’s AI Gigafactory initiative, which envisages large-scale facilities providing computing capacity for the development, training, fine-tuning, and deployment of advanced AI models and applications. These facilities are expected to combine AI-optimised computing, secure cloud access, high-capacity storage, advanced networking, energy-efficient data centres, and specialist support services. The stated priorities include improving access to hybrid compute, reducing operational costs and energy use through model compression and workload scheduling, and supporting deployments that meet European requirements for data protection, security, and technological autonomy.

Reliable piping infrastructure for high-density and AI workloads

As high-density racks and AI/ML clusters become standard, cooling systems must react quickly and reliably to changing loads. Liquid cooling circuits, combined with suitable piping systems, offer an effective way to manage these conditions. aquatherm blue is engineered for chilled- and process-water applications in data centres. Its PP-RCT material is resistant to corrosion, which supports long-term stability in temperature and flow. Fusion-welded joints create homogeneous, materially bonded connections, reducing leakage risk at critical points in the system. This robustness is particularly relevant where cooling must be maintained continuously and where downtimes are unacceptable. The system can be used for central chilled-water networks, rack-level cooling solutions, and the connection of heat exchangers in modern architectures.

Blueshift outlines thermal management for orbital data centres

US advanced materials company Blueshift has outlined a three-part thermal management approach for spacecraft in low Earth orbit (LEO), addressing the challenges posed by extreme temperature changes and increasingly powerful computing payloads. Presented at CAMX 2026, the approach treats thermal protection as an integral part of the spacecraft system. It focuses on moving internally generated heat to radiators for rejection at the highest practical temperature, controlling heat flow to protect temperature-sensitive components, and managing solar, Earth, and environmental exposure at the spacecraft surface. Blueshift reportedly has more than 20,000ft² (1,858m²) of its AeroZero Thermal Protection Systems (TPS) flying in LEO, alongside material testing and standards references including ASTM E595 and NASA-STD-6016. Spacecraft in LEO experience temperature swings from -180°C to +150°C between shadow and sunlight, with this cycle occurring 16 times a day. Computing payloads add to the challenge by generating substantial internal heat. Tim Burbey, co-founder and President of Blueshift, says thermal protection must be considered as part of the overall spacecraft design, regardless of vehicle type, noting, “Every spacecraft produces internal heat, and now we are seeing data centres produce 100 times more, forcing it to become a design driver.” Managing heat across spacecraft systems Blueshift says its AeroZero TPS materials can be used across the three areas of thermal management. Within the spacecraft, the material acts as a thermal break at brackets, joints, and other interfaces, helping to isolate batteries and temperature-sensitive components from hot electronics and coolant loops. This separation allows high-powered processors to determine the coolant loop temperature, enabling radiators to operate at higher temperatures and reject more heat per unit area. By separating hot and cold zones, the approach can also reduce radiator area and support smaller spacecraft thermal systems. In vacuum testing, Blueshift research found that AeroZero TPS had 19 times lower thermal conductivity and six times lower thermal diffusivity than standard polyimide tape. Thermal diffusivity determines how quickly temperature changes propagate through a thermal break, while the material is intended to buffer the temperature swings experienced every 90 minutes in LEO. In a modelled LEO scenario comparing thermal breaks, a solar cell mounted on a composite frame in sunlight ran almost 40°C cooler with AeroZero TPS than with standard tape. The comparison examined how thermal breaks could limit heat transfer between spacecraft structures and equipment. For exterior surfaces, Blueshift gives AeroZero TPS a solar absorptance-to-emittance ratio (α/ε) of 0.14, compared with 0.60 for uncoated Kapton. In illustrative steady-state calculations for a flat surface facing the Sun, the estimated surface temperature was -32°C (241 K) for AeroZero TPS and +73°C (346 K) for Kapton, a difference of 105°C. Tim concludes, “Supporting reliable, long-duration missions in increasingly demanding orbital environments is a key focus for Blueshift. Following CAMX, we look forward to further opportunities to showcase our AeroZero TPS portfolio and engage with spacecraft designers, engineers, and industry decision makers on how material innovation can support the next phase of commercial space development.”

Rethinking cybersecurity for an always-on digital enterprise

In this exclusive article for DCNN, Sharat Sinha (pictured above), CEO at Airtel Business, assesses how unified security platforms combining AI-driven threat detection, automated response, and human oversight can strengthen cyber resilience across increasingly complex digital environments: The world has entered an era where more than 20 billion connected devices generate continuous digital exhaust. Every transaction, sensor read, API call, and remote login now feeds a vast digital nervous system supporting economies, governments, and critical infrastructure. As adversaries weaponise automation and AI to scale reconnaissance and exploitation, the cyberattack surface has expanded faster than traditional defences can adapt. To safeguard national and enterprise resilience, security must evolve from fragmented, reactive controls to an AI-powered, human-led, always-on model delivered through a unified security platform. Traditional architectures were designed for static networks and stable perimeters; they were never built for cloud-native workloads, edge computing, distributed workforces, or API-centric digital ecosystems. Threat actors, however, now operate at machine speed, using AI to craft hyper-targeted phishing, escalate privileges autonomously, and exploit misconfigurations in minutes. Meanwhile, breach discovery in many organisations still spans months. This widening gap between attacker speed and defender response highlights the need for continuous, intelligence-driven protection across network, identity, cloud, and data layers. Using AI to identify weaknesses Within this shift, AI is emerging as a force multiplier - not a replacement - for human expertise. AI-driven analytics reduce false positives by up to 60%, correlate billions of signals across hybrid environments, and detect weak anomalies invisible to manual analysis. Predictive models identify the vulnerabilities most likely to be weaponised, shrinking patch backlogs and strengthening overall resilience. Behavioural algorithms reinforce identity security by spotting subtle deviations that precede credential compromise. Even configuration hygiene improves as AI continuously validates cloud and network settings, eliminating exposures before they become incidents. AI is also enabling entirely new security capabilities. AI assistants for security leaders can summarise incidents, explain posture drift, and produce board-ready insights in seconds. Autonomous SOC workflows now triage, enrich, and contain threats across identity, endpoint, and cloud layers. DevOps and cloud engineering teams use AI copilots to enforce guardrails and detect compliance drift, addressing misconfiguration risks that consistently rank amongst the top causes of breaches worldwide. These advancements reflect a broader global shift towards unified, AI-first cybersecurity platforms, where intelligence becomes the connective fabric linking telemetry from identity, network, cloud, and data. Rather than operating dozens of siloed tools, organisations gain a single operating layer where detection, decision making, and response flow seamlessly. This consolidation accelerates containment, eliminates blind spots, and frees up security teams to focus on high-impact decisions. AI also strengthens data protection and regulatory alignment, including emerging requirements under India’s DPDP Act. Automated data classification, policy violation monitoring, retention enforcement, and real-time breach alerts shift privacy oversight from periodic checks to continuous assurance. As India’s digital economy scales - driven by cloud adoption, fintech innovation, and public digital infrastructure - AI-driven governance ensures both compliance and protection without increasing operational burden. Confidence in an unpredictable landscape The global direction is clear: AI-first, human-centred, unified platforms are becoming the foundation of modern cyber resilience. With cyber incidents costing organisations millions of dollars and often causing systemic ripple effects, intelligent consolidation is no longer an efficiency strategy; it is a national and enterprise resilience strategy. Looking ahead, cybersecurity will be defined by how effectively organisations integrate AI across the entire lifecycle (posture management, threat prediction, protection, governance, and automated response) whilst empowering human judgement at every critical decision point. In a world where threats operate at machine speed, always-on, AI-powered, end-to-end protection is becoming the new standard. Organisations that embrace unified, AI-driven architectures will be best positioned to safeguard their people, data, and services with confidence in an increasingly unpredictable digital landscape.

Edge to core: Fibre infrastructure and the retrofit challenge

AFL, a manufacturer of fibre optic cables and connectivity equipment, has published a new blog exploring how distributed AI workloads change fibre infrastructure requirements across edge, metro/regional, and core environments. The blog also addresses a practical question for operators with facilities already in service: at what point does a brownfield retrofit stop making sense compared with a greenfield new build? Industry forecasts suggest inference will overtake training as the dominant use of AI data centres by 2027, shifting demand towards regional and edge sites that can respond within 1–10ms. This means edge, regional, and core tiers can no longer be planned as separate projects, since every tier depends on shared fibre infrastructure. The blog outlines what a fibre retrofit assessment should cover and explains how separating long-life backbone elements from short-life connectivity helps operators avoid designing for obsolescence.
