- 24/7Coverage
Six workstreams from on-prem to cloud-native.
Cloud assessment
Workload inventory, dependency mapping, target-platform fit assessment, cost modelling. Output: written migration roadmap with prioritised waves.
Architecture design
Landing zone design, identity federation, networking, security baselines, monitoring, backup. Cloud-adoption-framework aligned for Azure, AWS, or GCP.
Migration execution
Lift-and-shift, refactor, or replatform per workload. Database migrations, file-share migrations, application replatforming. Cutover rehearsed before the real one.
Optimization
Right-sizing, reserved-instance/savings-plan strategy, idle-resource cleanup, auto-scaling configuration. Most clients see 25-40% cost reduction post-optimization.
Security baselines
CIS benchmarks, secure landing zones, identity-first architecture, audit logging. Compliance-aware for ISO 27001, NIST CSF, SOX, NYDFS Part 500 clients.
Operations handover
Runbooks, monitoring dashboards, alerting integration, on-call escalation. Same team that migrated runs the cloud post-migration if you want continuity.
Cloud platforms we deploy and operate.
Four reasons clients pick us for the migration.
80+ migrations
Pattern recognition matters. We have moved workloads from on-prem to Azure, AWS, GCP across financial services, healthcare, retail, education.
Cost-discipline first
Cost modelling before migration, right-sizing during migration, optimization after migration. Most clients save 25-40% vs naive lift-and-shift.
Multi-cloud
Azure-native, AWS-native, GCP, plus hybrid configurations. We pick the platform that fits your workloads, not the one we resell.

The 6 R's of cloud migration.
Rehost (Lift and Shift)
Move applications as-is to the cloud with minimal changes. Best when speed matters more than cloud-native gains, or when the licence forces it. Fastest path to leaving the on-prem datacentre.
- Best for: time-sensitive migrations, quick wins
- Effort: low
- Benefit: fastest cutover, minimal risk
- Common workloads: Windows file servers, line-of-business apps
Replatform
Make minimal cloud optimisations without changing core architecture. Move database to managed RDS, swap NFS for managed file storage, containerise without redesign. Some cloud benefits without rewrite.
- Best for: balancing speed and optimisation
- Effort: medium
- Benefit: managed-service benefits, lower ops burden
- Common workloads: SQL Server to Azure SQL MI, MySQL to RDS
Refactor / Re-architect
Redesign applications to be cloud-native. Microservices, serverless functions, managed databases, container orchestration. Maximum cloud benefits, more time and risk in the move.
- Best for: long-term strategic value
- Effort: high
- Benefit: full cloud benefits, future-proof architecture
- Common workloads: legacy monoliths to microservices, container platforms
Repurchase (Replace)
Replace the application with a SaaS alternative. Common for CRM (Salesforce, Dynamics), HR (BambooHR, Workday), accounting (QuickBooks Online, Xero), email (M365, Workspace).
- Best for: standard business applications
- Effort: low (data migration only)
- Benefit: reduced maintenance, latest features
- Common workloads: legacy CRM, ERP, HRMS, email
Retire
Decommission applications that are no longer needed. Cloud assessment often reveals 10-20% of workloads are unused or duplicated. Retiring before migrating reduces scope and cost immediately.
- Best for: shadow-IT, unused or duplicated apps
- Effort: very low
- Benefit: reduced licence cost, smaller migration scope
- Common workloads: legacy reporting tools, old test environments
Retain
Keep certain workloads on-prem. Common for OT systems, regulator-bound data, hardware-tied licences, very recent capex. Hybrid architecture with cloud-on-prem connectivity preserves existing investment.
- Best for: OT systems, regulatory data, recent capex
- Effort: low (connectivity only)
- Benefit: preserves investment, regulator alignment
- Common workloads: SCADA, mainframes, on-prem-licensed apps

Optimize and operate
Continuous
Right-sizing, reserved-instance optimization, idle cleanup, ongoing monitoring. Steady-state cloud operations from week 1 post-migration.
“We had 23 on-prem servers running our trading floor and back office. GR IT spent four weeks on assessment, six weeks on design, and twelve weeks migrating to Azure with zero trading-day disruption. Two months post-migration, our cloud spend dropped 32% from the initial estimate after right-sizing and reserved instances. The cost discipline was as valuable as the migration itself.”
