Comparison Table
Capgemini
enterprise_vendorConsultancy delivering cloud migration advisory and implementation services.
Migration runbook and cutover planning artifacts that align wave sequencing with landing zone and dependency constraints.
Capgemini’s migration advisory approach combines workload discovery with application portfolio rationalization to separate rehost candidates from replatform and refactor targets. The program outputs commonly include migration runbook artifacts and cutover and rollback planning plans for each migration wave. Capgemini also brings identity and access architecture and network topology guidance into the cloud foundation work so teams do not design landing zones in isolation.
A key tradeoff is that advisory depth often increases delivery lead time because governance, architecture, and wave planning workshops require stakeholder attendance and decision windows. Capgemini fits best when an enterprise needs a controlled migration factory model across multiple business units and wants repeatable guardrails for execution, not just a one-time assessment.
- +Dependency-aware migration wave planning tied to landing zone constraints
- +Strong identity and access architecture guidance across target environments
- +Detailed cutover and rollback planning for staged execution
- +Clear governance guardrails for ongoing migration program control
- –Workshop-heavy approach requires consistent stakeholder availability
- –Advisory deliverables can require internal delivery bandwidth to operationalize
- –Extensibility tooling depends on integration with existing enterprise processes
- –Multicloud sequencing choices can add complexity for late decision teams

Best for: Fits when enterprise teams need governed migration planning across many apps and business units.
Infosys
enterprise_vendorGlobal consulting providing cloud migration advisory and modernization.
Dependency mapping plus workload discovery feeds migration wave planning with explicit runbook-ready sequencing artifacts.
Infosys works well when cloud migration requires more than app-by-app movement and instead needs coordinated planning across networking, security, and program delivery. Stronger signals include detailed dependency mapping, repeatable migration wave planning, and explicit landing zone and access control designs that support audit-ready governance workflows. Delivery fit is highest for multi-workload programs where migration sequencing affects cutover planning and operational readiness.
A key tradeoff is that Infosys’ advisory depth can demand tighter client governance and decision cadence to keep migration waves moving. Infosys fits situations where a large enterprise needs workload placement guidance, a staged cutover and rollback approach, and consistent execution through a migration runbook.
- +Detailed dependency mapping drives practical migration wave sequencing
- +Landing zone design and identity architecture support governance guardrails
- +Clear application rationalization inputs for rehost versus replatform decisions
- +Execution workflows turn advisory outputs into migration runbooks
- –Requires strong client decision cadence to avoid wave delays
- –Best results depend on providing accurate application and dependency inventory

Best for: Fits when large enterprises need structured migration planning and governed execution across many workloads.
Deloitte
enterprise_vendorBig Four consultancy providing cloud migration and modernization advisory.
Cloud operating model and wave planning artifacts that tie governance guardrails to execution runbooks and cutover readiness.
Deloitte fits large enterprises that need structured decision support across cloud adoption, from cloud readiness and dependency mapping to workload placement and sequencing. Engagement teams commonly bring coverage for identity and access architecture, connectivity architecture, and hybrid cloud integration points that are prerequisites for safe workload moves. The advisory output tends to include migration runbook structures, rollback planning expectations, and cutover planning guidance that supports disciplined execution.
A practical tradeoff is that Deloitte’s value concentrates when leadership expects governance guardrails and defined delivery processes, because advisory quality depends on timely client inputs and target-state clarity. Deloitte works well when multiple business units and application owners must align on rehost versus replatform versus refactor decisions and when wave planning must coordinate dependencies across portfolios. Deloitte is less efficient for teams seeking only tactical technical design without migration factory-style sequencing artifacts.
- +Produces migration wave plans with cutover and rollback expectations
- +Translates identity and network constraints into governance guardrails
- +Builds cloud operating model artifacts for multi-wave execution
- +Connects workload discovery to portfolio decisions across teams
- –Advisory output requires strong client participation and decision ownership
- –Less suited for narrow migrations without broader operating model work
- –Engagement artifacts can be heavy for teams wanting lightweight guidance
- –Requires tight coordination with implementers to realize sequencing guidance

How to Choose the Right Cloud Migration Advisory
We separate cloud migration advisory tools by how they turn strategy into execution: they differ most in the Migration runbook, the Automation and API surface, and the Audit log and RBAC controls. When these three are weak, the plan stays a slide deck instead of a controlled migration workflow.
Migration runbook readiness
Why it matters
Migration runbook readiness matters because advisory only becomes usable when it includes step-level actions, owners, and decision points. For cloud migration advisory, readers need a repeatable path for how work should start, proceed, and end.
How to check
Ask for a sample runbook that covers discovery-to-cutover and includes clear prerequisites and rollback decision triggers. In the demo, pick one migration stage and confirm you can export the runbook for your team to operate without extra back-and-forth.
API and automation surface depth
Why it matters
API and automation surface depth matters because advisors save time when they connect to your existing tools and keep decisions synchronized. Strong integration also helps you apply the same advisory outputs across multiple environments.
How to check
On a demo, request an API call or workflow that updates one advisory artifact after you change a plan input. Ask what objects can be created or updated via API, and what automation exists for recurring migrations.
Audit log and RBAC controls
Why it matters
Audit log and RBAC controls matter because advisory work often involves many contributors and sensitive architecture notes. Without traceability, you cannot prove who approved changes or why a decision was updated.
How to check
Request to view an audit trail for a plan change, including timestamp and actor. In the admin screens, verify role-based permissions (read vs edit vs approve) and confirm you can restrict access to project data.
Data model and change tracking
Why it matters
Data model and change tracking matter because advisory outputs lose value when they can’t be versioned against new findings. You need stable fields for workloads, dependencies, and migration decisions so updates don’t break earlier work.
How to check
Ask how the tool represents a workload and migration decision, then check whether revisions keep history. Try changing one input in a sandbox project and confirm the tool shows what downstream outputs were affected.
Governance guardrails for approvals
Why it matters
Governance guardrails for approvals matters because migration decisions need controlled signoff paths, not ad-hoc edits. Good guardrails reduce the risk of inconsistent waves and mismatched environments.
How to check
In the demo, set up a simple approval flow for a migration wave artifact and confirm state transitions (draft, review, approved). Ask whether you can require specific fields to be completed before approval.
Red flags
- Runbooks are high-level checklists with no owners, prerequisites, or rollback triggers.
- APIs or exports don’t let your team keep advisory outputs synchronized after input changes.
- Audit trails and permissions are missing or don’t distinguish who approved what.
Fit by situation
- If you need to hand execution tasks to multiple teams, prioritize Migration runbook readiness.
- If you already run planning workflows in-house, prioritize API and automation surface depth.
- If several teams will edit architecture and decisions, prioritize Audit log and RBAC controls.
