“Cloud & Cyber” Center of Excellence (CoE)
Modern Cloud & Infrastructure Strategy
- Aligned roadmap with business challenges: we assess your organizational model, cloud maturity, and key challenges, then define the strategy (technology choices, use cases, target architectures, governance) and your roadmap, integrating security, sovereignty, and business requirements from the outset.
- Application and infrastructure transformation: we support the integration of market-leading and/or sovereign solutions, and the modernization of applications and infrastructure toward cloud-native, hybrid, containerized (Kubernetes, OpenShift), or private (OpenStack) models.
Intelligent Networks & Connectivity
- Operational continuity: we ensure reliable connectivity between your sites, cloud environments, digital platforms, telecom networks, and IoT equipment, which is essential to the continuity of your operations.
- Scaling digital and industrial use cases: we deploy WAN (Wide Area Network) architectures, 5G, and IoT sensors to enable data collection and the large-scale rollout of Cloud, Data, AI, and IoT use cases across all client sites.
Cloud‑Native Operations & DevSecOps
- Industrialization of environments: through our DevSecOps practices integrating security by design, automation, and AI-augmented operations (AIOps), we reduce incidents, accelerate production releases, and sustainably optimize operational costs.
- Deployment security: implementation of secure and automated CI/CD pipelines, combining Infrastructure as Code, embedded security controls, and continuous deployments to accelerate and secure production releases.
- AI-augmented operations: we leverage advanced analysis of metrics, logs, and events to anticipate incidents, optimize performance, and automate remediation actions.

Cloud & Big Data Acceleration: Operational Excellence and GCP Migration via a Dedicated Center
Astek supports teams of a leading European telecommunications operator responsible for Run/Maintenance (MCO/MCS) of Big Data platforms through a dedicated skills pool, outsourced since 2023 within a Delivery Center in Rennes. The setup covers all technologies around Hadoop clusters and GCP Cloud environments.
Support spans Hadoop cluster administration, user support, GCP project administration and support, cloud migration advisory, documentation maintenance, and operational team governance. Astek ensures high service availability, rapid scalability, strict adherence to procedures and KPIs, and long-term skills continuity—driving performance and reliability of the client’s Big Data platforms.
Operational Continuity of the Brazilian Naval Program
As part of a strategic defense export program (submarine construction), the Group steers the Run & Maintenance (MCO) and evolution of a critical application ecosystem. Beyond corrective and evolutive Application Maintenance (AMS), our teams deliver reliability engineering and deploy major releases on international sites—ensuring operational availability and service continuity of sovereign systems in complex environments.
Accelerating the Digital Pivot and Scaling a Subscription Model for a Wellness Market Leader
For a long-established healthcare player (publicly listed, 60+ years), we orchestrated the critical transition from a traditional physical model to a Digital-First growth strategy focused on recurring revenue. The challenge was to transform a legacy organization into a digital subscription platform serving 2.5 million customers, while outperforming pure digital players in agility.
By leading full Cloud migration and adopting a scalable open-source architecture, we drastically reduced time-to-market for new offerings and turned IT infrastructure into a profitability lever. This transformation enabled the Group to successfully pivot its business model, absorb massive subscriber growth without proportional operating cost increases, and secure margins and leadership in a highly competitive market.
Cloud Data Strategy: Data Governance and Cloud Transformation for Airport Operational Excellence
For a leading airport infrastructure operator, the Group orchestrates the transition to a Data-Driven Cloud model by designing a global governance strategy. The engagement combines definition of a target governance framework (GDO) with technical implementation of a Microsoft Purview & Azure ecosystem—structuring security, compliance, and data quality to turn Cloud into an agile, strategic decision-making lever for airport performance.
Cloud Strategy & Cyber Resilience: Multi-Cloud Strategy, Security, and Microsegmentation for a Banking Industry Player
For a leading European banking group, the Group secures cloud-native environments within a complex Multi-Cloud architecture (Azure & IBM). The mission transforms a traditional perimeter-based security model into a microsegmentation strategy (Illumio) combined with native filtering (ACLs, Security Groups).
This approach ensures granular traffic protection, strict compliance of application migrations, and precise governance of network resilience against cyber threats.
