Case Study
Azure “Lift and Shift” Migration
Cloud Enablement
Vodafone Ireland partnered with SevTech to migrate over 50 critical applications to Microsoft Azure, enhancing scalability, performance, and cost efficiency. Prompted by aging data center infrastructure, the move ensured a secure, future-ready cloud environment. SevTech’s expertise enabled a smooth transition with minimal disruption and full application continuity.
Overview
Zurich Insurance partnered with SevTech to define a comprehensive Cloud Migration Strategy, enabling the transition of critical applications from a legacy London-based data center to a multi-cloud environment leveraging AWS and Azure.
SevTech conducted in-depth assessments, facilitated workshops with key stakeholders, and developed a structured roadmap to ensure a smooth and risk-mitigated migration. The strategy aimed to optimise cloud adoption while aligning with Zurich’s business objectives, IT governance, and operational needs.
Challenge
Zurich needed a structured and strategic approach to migrate 59 critical applications to the cloud while maintaining operational resilience. Key challenges included:
Selecting the optimal cloud provider for each application.
Ensuring minimal disruption to business operations.
Managing dependencies between cloud and on-premise applications.
Aligning with Zurich’s global IT governance, security, and compliance standards.
Results
Phased Migration Plan: A structured, risk-mitigated approach for transitioning applications.
Optimised Cloud: Partnering AWS and Azure alignment based on application needs.
Robust Governance Model: Defined roles and responsibilities across Zurich, DXC, and CCOE.
Future-Proofing IT Infrastructure: A scalable cloud strategy supporting Zurich’s long-term digital transformation.
Solution
SevTech conducted in-depth assessments of Zurich’s application landscape, evaluating each application’s suitability for AWS or Azure. A four-phase migration approach was defined, starting with pilot applications and progressing to more critical systems.
The strategy incorporated a tailored operating model, a governance framework, and a clear RACI structure, ensuring seamless execution while aligning with Zurich’s Cloud Centre of Excellence (CCOE) and DXC, its managed service provider.
