Cloud Modernisation & Transformation
We take a technical, structured approach to cloud transformation — starting with how your estate actually runs today, not how it looks on a slide. Application dependencies, integration points, and operational constraints are mapped first; migration plans follow. Our cloud architects and engineers deliver across Amazon Web Services, Microsoft Azure, Google Cloud Platform, Red Hat OpenShift, OpenStack, and VMware.
Lay of the Land
Before any target architecture is drawn, we establish a clear picture of the current environment — workloads, hosting, networks, data flows, ownership, and operational support. You know what is in scope, what is fragile, and what cannot move without downstream impact.
Cloud Architects & Engineers
SolStak's cloud architects and engineers work across the platforms you run today and the ones you are moving toward — including Amazon Web Services, Microsoft Azure, Google Cloud Platform, Red Hat OpenShift, OpenStack, and VMware. Whether the target is public cloud, private cloud, hybrid, or containerised, we design and build with platform-native patterns rather than one-size-fits-all templates.
Application Dependencies
Applications rarely move in isolation. We document upstream and downstream dependencies, batch interfaces, shared services, and identity integrations so migration sequencing is based on fact — not assumption.
OSI Stack Breakdown
Each application is assessed layer by layer across the OSI model — physical and virtual infrastructure, network paths, transport and session behaviour, application protocols, and data semantics. That breakdown exposes where complexity lives and where cutover risk concentrates.
Migration Strategy & the 6 Rs
We classify each workload using the 6 Rs — Rehost, Replatform, Refactor, Retire, Retain, and Repurchase — and build a migration strategy that matches business priority, technical readiness, and assurance requirements. Not everything should move; not everything should stay.
Migration Planning & Delivery
From strategy to execution, we produce migration plans with defined waves, rollback positions, test criteria, and cutover steps. Delivery is staged so teams retain service continuity while the estate shifts toward the target cloud operating model.
Security & Operational Readiness
Security, monitoring, backup, and run-state controls are designed into the transition — aligned with IRAP, ISM, and enterprise governance where required. The goal is a cloud environment your teams can operate and defend, not just migrate into.
