Cloud Architecture & Migration
Design a sound cloud architecture and migration strategy before committing to cloud spend — vendor-neutral, business-aligned, and built to govern.
Understanding This Service
What We Design
We assess your current IT landscape, define a target cloud architecture, and produce a phased migration roadmap — covering workload classification, provider selection rationale, and hybrid cloud governance.
Architecture-First Approach
Cloud migrations that skip the architecture phase routinely fail or overspend. We apply TOGAF® ADM principles to ensure your cloud strategy is aligned to business objectives before any workloads move.
Vendor-Neutral Advisory
We are vendor-neutral and advise on AWS, Microsoft Azure, and Google Cloud based on your specific workload characteristics, cost profile, and existing technology investments.
Why Clients Request This Service
No defined cloud target architecture
Stalled or failed migration attempts
Unclear workload suitability for cloud
Uncontrolled cloud costs and governance gaps
Scope of Testing
Our Cloud Architecture & Migration engagement covers:
Workload Assessment
Inventory and classification of your application portfolio by cloud readiness, migration complexity, and business criticality.
Target Cloud Architecture
Design of your target cloud architecture including landing zone, network topology, identity management, and security baseline.
Migration Strategy
Per-workload migration strategy selection (rehost, replatform, refactor, retire, retain) with rationale and dependency mapping.
Governance Framework
Cloud governance design covering cost management, policy enforcement, tagging standards, and operational model for hybrid environments.
Migration Roadmap
Phased, prioritised migration roadmap with wave planning, timeline estimates, and risk assessment per migration wave.
How We Run This Engagement
Discovery
Landscape inventory, stakeholder interviews, and current-state architecture review focused on cloud-relevant characteristics.
Workload Assessment
Classification of applications and infrastructure by cloud readiness, migration complexity, and strategic value.
Architecture Design
Target cloud architecture design including landing zone, network, identity, and security baseline.
Migration Planning
Migration strategy selection per workload, dependency mapping, and wave planning with risk assessment.
Roadmap Delivery
Final migration roadmap presentation with governance framework and go-forward operating model.
What You Walk Away With

What Makes Our Testing Different
Cloud Architecture & Migration consulting from Portamus ensures your organisation designs its cloud strategy before committing to migration — avoiding the costly mistakes that result from lifting and shifting without an architectural foundation. We apply TOGAF® ADM principles to produce a target cloud architecture, assess your workload portfolio for cloud suitability, and deliver a phased migration roadmap that is realistic about complexity, cost, and risk. The result is a cloud strategy your leadership can fund with confidence and your IT teams can execute without surprises.
