One question drives everything we do in this engagement: "What should move, why, when, and how?" We answer it with rigour — covering business case, current-state analysis, workload assessment, security, architecture, cost, and a practical roadmap.
Define the business goals driving cloud adoption and align stakeholders on what success looks like.
Every cloud strategy begins with a clear understanding of why the organisation is moving. We work with your leadership team to articulate the primary drivers — whether that is cost reduction, scalability, faster product delivery, resilience, modernisation, or regulatory compliance.
This phase identifies key stakeholders and their priorities, establishes measurable success metrics, and surfaces any industry-specific constraints such as data residency requirements, sector regulations, or board-level risk appetite. The output is a shared definition of scope and a set of guiding principles that will govern every decision downstream.
A detailed inventory of your existing IT landscape — infrastructure, applications, data, and operations.
You cannot plan a migration without knowing what you have. Our discovery process produces a comprehensive picture of your current environment through a combination of automated tooling, stakeholder interviews, and documentation review.
We document every layer of the stack: physical and virtual infrastructure, application portfolio, data platforms and flows, network topology, identity and access model, security controls, and operational processes. Dependency mapping is a critical output here — understanding what talks to what prevents costly surprises during migration.
Every application evaluated for cloud suitability with a clear disposition recommendation.
Not every workload belongs in the cloud, and not every workload should move the same way. We assess each application or service against a consistent framework covering business criticality, technical complexity, dependency footprint, performance requirements, licensing constraints, and supportability.
The output for each workload is a disposition recommendation using the standard 6-R model. This becomes the foundation of the migration roadmap and ensures effort is directed where it delivers the most value.
Assess your current security posture and define what changes are required in the cloud model.
Security cannot be retrofitted. This section evaluates your existing controls against cloud-native security requirements and identifies the gaps that must be addressed before, during, and after migration.
We review identity and access management, encryption at rest and in transit, logging and monitoring coverage, vulnerability management practices, data classification and protection, and audit trail requirements. Where applicable standards such as GDPR, HIPAA, PCI DSS, or ISO 27001 apply, we map your current posture against those frameworks and produce a remediation plan.
Define the target cloud model, provider selection, and high-level architecture direction.
With the current state understood and workloads assessed, we define the target architecture. This includes cloud provider selection or multi-cloud strategy, landing zone design principles, network architecture, tenancy model, and governance framework.
We evaluate public, private, hybrid, and multi-cloud options against your requirements and produce a reference architecture that will guide the detailed design phase. Provider selection is always driven by workload fit, commercial terms, and your team's existing skills — not by partner incentives.
Compare current costs with projected cloud spend and build the financial case for leadership.
Cloud should deliver measurable financial value. We build a detailed total cost of ownership model that compares your current on-premises or legacy costs — including hardware refresh cycles, data centre costs, licensing, and operational overhead — against projected cloud costs across compute, storage, networking, and managed services.
The business case includes ROI analysis, migration effort and one-time costs, ongoing run rate, reserved capacity and savings plan opportunities, and a payback period. The output is a financial recommendation that leadership can take to the board.
Address the people and process changes required to operate effectively in the cloud.
Technology is the easy part. The organisations that struggle with cloud are almost always dealing with a skills gap, an unclear operating model, or a governance structure that was designed for on-premises. We assess your team's current cloud maturity and define what needs to change.
This covers cloud skills gaps and training plans, DevOps and automation maturity, support model design (who owns what in the cloud), governance readiness, and how day-to-day operations will change post-migration. We also define the target operating model so your team knows exactly what they are building towards.
Turn all findings into a phased, actionable migration plan with clear priorities and next steps.
The roadmap is the deliverable that ties everything together. It translates the findings from every preceding section into a sequenced, phase-wise migration plan that is realistic, risk-managed, and aligned to your business priorities.
We identify quick wins that can demonstrate value early, sequence complex workloads to minimise risk, and define clear milestones and success criteria for each phase. The executive summary distils the entire assessment into a concise narrative for leadership, with a clear recommendation on how to proceed.
