Cloud Migration Strategy

Overview

Vodafone partnered with SevTech to define a Cloud Migration Strategy for transitioning its extensive application landscape from legacy data centres to a multi-cloud environment spanning AWS, Azure and Oracle Cloud.

SevTech conducted an in-depth assessment, engaged key stakeholders through workshops and developed a structured roadmap to ensure a seamless, secure and efficient migration. The strategy prioritised scalability, performance optimisation and long-term cost efficiency.

Challenge

Vodafone’s existing IT infrastructure was heavily reliant on ageing, on-premises data centres, leading to high maintenance costs and operational inefficiencies. Migrating to the Cloud required careful selection of cloud platforms, ensuring regulatory compliance, minimising service disruptions and managing complex application interdependencies.

Additionally, Vodafone needed a clear governance and operating model to effectively manage workloads across multiple cloud providers while ensuring security and performance consistency.

Results

• Phased migration roadmap: Minimise risk and operational disruption.

• Optimal Cloud Placement: Aligning applications to AWS, Azure or Oracle based on performance and cost.

• Enhanced Business Agility: Scalable, cloud-native infrastructure.

• Long-term cost efficiency: Optimised cloud resource utilisation.

Solution

SevTech executed a comprehensive cloud assessment, categorising Vodafone’s applications based on technical feasibility, cost and business impact.

A phased migration plan was developed, starting with non-critical applications before transitioning mission-critical systems. The strategy leveraged AWS, Azure and Oracle Cloud to align with specific workload requirements. SevTech also designed a governance framework and a cloud operating model to ensure a smooth transition and ongoing cloud management.
