The Challenge
The organisation was operating over 200 on-premises servers across a London data centre, with prior disaster recovery hosted in Singapore. Aging infrastructure, high operational costs, and complex maintenance meant the existing environment was no longer sustainable.
The customer needed a modern, secure, and scalable cloud platform that could:
Replace the legacy data centre without disrupting business-critical workloads
Maintain strict security, compliance, and identity controls
Provide rapid disaster recovery and resilience
Reduce operational and capital expenditure
Enable future growth and cloud-first adoption

The Solution
Venture 1 delivered a structured, phased migration of the entire on-premises estate into Microsoft Azure. The solution provided a secure, scalable, and cost-efficient cloud environment while maintaining operational continuity and compliance requirements.
Key elements of the solution included:
Discovery & Analysis: Identified dependencies, performance requirements, and potential migration risks.
Design & Planning: Developed high-level and low-level architecture documentation, including security, networking, and DR considerations.
Execution: Migrated workloads using a phased approach, optimising infrastructure and selectively re-engineering applications to improve performance and resilience.
Validation & Knowledge Transfer: Verified system integrity and provided training and documentation for ongoing management and governance.
The solution replaced a costly legacy data centre with a modern cloud environment, enabling operational agility, improved security, and future growth.
Benefits & Results Derived
Significant Cost Savings: Eliminated the need for data centre refurbishment and reduced operational expenditure.
Enhanced Security & Compliance: Cloud-based identity, access, and policy controls strengthened the organisation’s compliance posture.
Reliable Disaster Recovery: Azure-based DR capabilities improved resilience and reduced recovery times compared to previous setups.
Optimised Workloads & Modern Infrastructure: Selective re-engineering and cloud optimisation enhanced performance, reliability, and efficiency.
Operational Agility: The cloud-first model positioned IT teams to adopt new services and scale quickly.
Scalable, Future-Ready Environment: Established a foundation for further Azure adoption, cost management, and governance improvements.
