Cloud & Infrastructure
Digital Foundations
Drive performance through intelligent, resilient, and scalable cloud infrastructures.
Adopting a Cloud ecosystem and interconnected enterprise platforms acts as a triple driver of performance
Operational Agility & Scalability
Define your Cloud or Multi-Cloud trajectory to modernize applications and infrastructures. By adopting hybrid, containerized, or private models, you ensure service scalability while optimizing costs and accelerating release cycles.
Platform Integration & Performance
Integrate best-in-class solutions and guarantee interoperability to break down data silos and transform operating models. By eliminating technological fragmentation, you streamline business flows, rationalize application landscapes, and optimize maintenance and operating costs.
Connectivity & Operational Excellence
Design resilient critical networks (5G, IoT, WAN) and industrialize operations through a DevOps culture. By securing data flows and automating deployments, you ensure rigorous performance governance and high availability of services worldwide.
Accelerate your technology transformation and Cloud journey, combining performance, sovereignty, and security
In a context of increasing cost pressure, growing Cloud dependency, and rising operational risks, we help organizations build high‑performance, secure, and resilient Cloud infrastructures, leveraging automation and AI‑enhanced operations to support sustainable growth. Astek acts as a trusted partner to define your target architecture and lead your transformation.
We support the redesign of your technology foundation and operating model, from defining your Cloud roadmap to optimizing intelligent networks and platforms. We transform your processes, tools, and operating methods.

“Cloud & Cyber” Center of Excellence (CoE)
Modern Cloud & Infrastructure Strategy
- Definition and governance of your Cloud and Multicloud journey: we assess your organizational model, cloud maturity, and business challenges, then define your cloud strategy (technology choices, use cases, target architectures, and governance) and your roadmap, integrating security, compliance, sovereignty, and business requirements from the design phase onward.
- Solution integration and transformation: support for the integration of leading market and/or sovereign solutions, and the modernization of applications and infrastructures toward cloud‑native, hybrid, containerized (Kubernetes, OpenShift), or private (OpenStack) models, ensuring agility, scalability, and resilience.
Intelligent Networks & Connectivity
- Design, security, and operation of mission‑critical enterprise networks: we ensure reliable connectivity across your sites, Cloud environments, and digital platforms—essential to business continuity.
- Critical and resilient connectivity: expertise across WAN, 5G, and IoT architectures, with a performance‑driven approach focused on resilience and data‑flow security, delivering global, seamless, and reliable connectivity.
Cloud‑Native Operations & DevSecOps
- Industrialization of Cloud environments and infrastructures: leveraging our DevSecOps practices, combining security by design, automation, and AI‑enhanced operations (AIOps), we reduce incidents, accelerate releases, and sustainably optimize operational costs.
- Secure deployment industrialization: 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‑enhanced operations: we rely on advanced analysis of metrics, logs, and events to proactively 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.
