Cloud Migration & Modernisation for UK Businesses
Organisations with legacy on-premises infrastructure face rising maintenance costs, limited scalability, and increasing security risks. Failed or stalled migrations waste budgets and leave businesses stuck between two worlds.
Our Solution
Cloudshire provides structured, low-risk cloud migration and modernisation services. We move workloads to AWS, Azure, or GCP with minimal disruption while modernising applications to exploit cloud-native capabilities.
The Challenge
Legacy infrastructure constrains business agility and accumulates technical debt. On-premises servers reach end-of-life, maintenance contracts escalate, and scaling to meet demand becomes expensive and slow.
Many organisations attempt migrations without structured planning, resulting in stalled projects, budget overruns, and hybrid states that combine the costs of both environments. Applications moved without modernisation often perform worse in cloud than on-premises.
The longer organisations delay, the greater the risk from unsupported platforms, unpatched systems, and inability to adopt modern services.
Our Approach
Cloudshire’s migration specialists have moved hundreds of workloads to cloud across AWS, Azure, and GCP. We combine proven methodologies with practical engineering to deliver migrations that stay on budget and on schedule.
We start with portfolio assessment to prioritise workloads by business value, complexity, and risk. Each application gets the right migration strategy — not every workload needs refactoring, and not every workload should simply be lifted and shifted.
Our wave-based execution model manages risk through incremental delivery. Each wave is tested, validated, and optimised before the next begins.
The Process
Our four-phase approach provides structure while remaining adaptable to your specific context.
Step 1 — Assessment & Planning. We discover your application portfolio, map dependencies, assess cloud readiness, and build a prioritised migration plan with clear business cases for each workload.
Step 2 — Migration Strategy. For each workload, we define the optimal approach: rehost for quick wins, replatform for moderate gains, or refactor/rebuild for maximum cloud-native benefit.
Step 3 — Execution & Migration. We execute migrations in controlled waves using automated tooling, rehearsal runs, and validated runbooks. Rollback plans ensure every cutover is reversible.
Step 4 — Optimisation & Handover. Post-migration, we right-size resources, implement cost controls, and hand over with full documentation and team training.
Outcomes You Can Expect
Clients typically achieve 30-50% infrastructure cost reduction within six months of migration. Applications gain improved availability through cloud resilience patterns and auto-scaling capabilities.
Teams accelerate delivery by adopting cloud-native CI/CD and managed services. End-of-life infrastructure risk is eliminated, and compliance posture improves through cloud provider security controls.
Frequently Asked Questions
What is cloud modernisation?
Cloud modernisation transforms legacy applications to exploit cloud-native services. This includes containerisation, serverless adoption, managed database migration, and event-driven architecture patterns that improve performance and reduce operational overhead.
How does Cloudshire handle data migration?
We use provider-native migration services (AWS DMS, Azure Database Migration Service) combined with custom tooling for complex scenarios. Data integrity is validated at every stage with automated comparison and reconciliation checks.
Do you support migrations to any cloud provider?
Yes. We deliver migrations to AWS, Azure, and GCP based on your requirements. Our vendor-agnostic approach ensures the target platform is chosen for fit rather than familiarity.
Our Process
-
Assessment & Planning
We assess your application portfolio, dependencies, and data flows to build a prioritised migration plan with clear business cases.
-
Migration Strategy
We define the right approach for each workload — rehost, replatform, refactor, or rebuild — based on value and complexity.
-
Execution & Migration
We execute migrations in waves, using automated tooling and proven runbooks to minimise downtime and risk.
-
Optimisation & Handover
Post-migration, we optimise for cost and performance, then hand over with documentation and team enablement.
Expected Outcomes
- 30-50% reduction in infrastructure costs post-migration
- Zero or near-zero downtime migrations using proven patterns
- Improved application performance through cloud-native optimisation
- Eliminated end-of-life infrastructure risk and technical debt
Frequently Asked Questions
- What is cloud migration?
- Cloud migration is the process of moving applications, data, and infrastructure from on-premises data centres to cloud platforms. It encompasses planning, execution, testing, and optimisation of workloads in their new cloud environment.
- How does Cloudshire minimise migration risk?
- We use a wave-based approach with automated discovery, dependency mapping, and rehearsal migrations. Each wave is tested and validated before cutover, with rollback plans in place for every workload.
- How long does a typical cloud migration take?
- Timelines vary by portfolio size. A single application can migrate in 2-4 weeks. An enterprise portfolio of 50+ applications typically takes 3-6 months using a phased wave approach.
- What is the difference between migration and modernisation?
- Migration moves workloads to cloud with minimal changes (rehost/replatform). Modernisation transforms applications to use cloud-native services like containers, serverless, and managed databases for greater efficiency.
