The rapid evolution of cloud technologies requires companies to modernize their IT infrastructure to stay competitive. Migrating information systems to high-performance cloud platforms enables the optimization of security, flexibility, and cost management. This migration project aims to support a telecom infrastructure operator in transitioning its core applications to a new cloud platform, while minimizing the impact on operations and partners. The success of this transformation relies on meticulous planning, controlled execution, and adherence to best practices in the industry.
Client’s needs: migration to a modern Cloud platform
Facing the end of support for a legacy cloud service, it becomes imperative for the organization to migrate its critical applications to a more modern and efficient platform. The migration must address several key challenges:
- Ensure business continuity without major disruptions: the migration should be carried out with minimal impact on users and partners.
- Optimize operational costs: reduce expenses related to infrastructure management while maintaining high performance.
- Strengthen data and application security: comply with industry security standards to protect critical assets.
- Facilitate integration and management of new platforms: automate deployment and resource management to enhance agility.
- Prepare for the future with SaaS architecture: simplify maintenance and application evolution through a modern architecture.
- Meet deadlines and regulatory constraints: plan the migration carefully to avoid delays or non-compliance.
Sofrecom methodology for a successful Cloud migration
To effectively support this transition, Sofrecom adopts a structured approach focused on risk management and maximizing benefits. Its methodology is based on several key phases, each essential to ensuring a smooth and secure migration:
Precise mapping of the existing infrastructure: analyze the current environment to identify all applications, dependencies, and configurations.
Design of the target environment on Google Cloud Platform (GCP): define a tailored architecture aligned with future needs, incorporating best practices.
Compliance with GCP standards for security, performance, and costs: implement recommendations to ensure a robust and optimized infrastructure.
Deployment automation with GitOps: leverage Terraform, GitLab CI, Helm, and Flux to deploy and manage resources automatically and reproducibly.
Cost planning and management with FinOps: optimize resource usage to reduce expenses while maintaining performance.
Close collaboration with stakeholders: ensure smooth communication with internal teams, partners, and suppliers to anticipate and resolve potential obstacles.
Progressive and secure migration: transfer data and applications in stages to limit risks and ensure an interruption-free transition.
Training and team support: guarantee effective adoption of new technologies and processes.
