Building a global file service platform and automated migration of 6 PB of data to Microsoft Azure across multiple Siemens business sectors.

Challenge / Problem

Siemens faced the challenge of consolidating globally distributed file systems. Different local IT infrastructures led to high operating costs, limited scalability, and security risks related to data access and management.

  • Decentralized file storage across global locations with complex access rights
  • High administrative effort with limited scalability
  • Security gaps caused by outdated infrastructure
  • High IT operating costs due to multiple local IT providers
  • No centralized system for cost allocation and monitoring


Our Approach

CloudAstro designed a global, standardized file service concept focused on security, scalability, and automation—tailored to the requirements of a large international enterprise.

  • Development of a global file service based on a Zero Trust security architecture
  • Scalable model for access rights and identity management
  • Consistent use of Infrastructure as Code and DevOps principles
  • Unified approach to permissions and identity management
  • Phased migration with pilot projects and continuous testing

Implementation

The solution was implemented using a highly automated and standardized approach to deliver a secure, reproducible, and globally scalable platform on Microsoft Azure.

  • Automated migration of 6 PB of data to Microsoft Azure (project in progress)
  • Entire infrastructure defined via Terraform and controlled through automated pipelines
  • Automated provisioning of scalable infrastructure
  • Implementation of a Zero Trust security architecture
  • Deployment of a monitoring solution for the global file service platform in Azure

Results

The new file service platform provides a unified, secure, and cost-efficient foundation for global collaboration and modern work at Siemens.

  • 20% reduction in operating costs through optimized IT infrastructure and centralization on Microsoft Azure
  • Global, unified file service platform for over 300,000 Siemens users—highly available and scalable worldwide
  • Significant reduction in total costs by eliminating legacy infrastructure and reducing administrative overhead
  • Increased productivity and flexibility for employees
  • Future-ready remote workplaces with strong compliance and security
