Comparison Table
Cognizant
enterprise_vendorGlobal IT services provider delivering cloud migration, application modernization, and cloud operations.
Program-level orchestration that links dependency discovery, wave sequencing, and cutover engineering across many applications.
Cognizant’s migration approach starts with application and dependency discovery that feeds migration readiness and wave planning, then moves into implementation across rehost, replatform, and refactor tracks under a controlled cutover plan. Engineering delivery commonly pairs landing zone configuration with infrastructure as code so environments, networking, and access controls can be replicated across multiple waves. API integration and automation matter in the program context, since Cognizant workstreams often need repeatable provisioning steps, environment promotion, and deployment orchestration for many applications.
A tradeoff shows up in implementation style because Cognizant delivery tends to expect strong enterprise input for target architecture decisions, shared tooling standards, and access approvals. Cognizant fits best when an enterprise needs a migration program manager plus engineers who can coordinate application, data, and connectivity workstreams into a single delivery timeline. It is also a strong fit for organizations using hybrid connectivity and private connectivity patterns where cutovers require careful rollback and rollback-ready deployment planning.
- +Dependency-driven wave planning for large enterprise application portfolios
- +Infrastructure as code usage supports repeatable environment provisioning
- +Engineering support for cutover and rollback planning across migration waves
- +Hybrid connectivity coordination for enterprise target environments
- –Requires enterprise decision speed for target architecture and access controls
- –Automation depth depends on alignment with existing toolchain standards

It then translates those findings into 6R strategy, target-state architecture, and detailed cutover and rollback planning for each migration wave. Deloitte adds operational rigor through observability and disaster recovery testing planning so migrations include run readiness rather than stopping at deployment.
A tradeoff is that Deloitte’s program depth can require stronger internal sponsorship and faster decision cycles for target architecture, identity federation, and environment standards. This fits situations where enterprise governance, multi-team coordination, and risk controls are part of the definition of done, such as regulated industries with many interconnected apps.
- +Strong migration readiness and dependency mapping for wave planning
- +Clear 6R strategy outputs tied to target-state architecture decisions
- +Governance-focused delivery for identity federation and environment standards
- +Run-readiness planning that includes disaster recovery testing approach

How to Choose the Right Cloud Application Migration
Options differ most in how much migration control they give you over the application inventory, the cutover lifecycle, and the repeatability of deployments. In practice, mapping out cutover and rollback options, and how testing results feed them, separates the tools you can trust from the ones that only move code.
Migration planning visibility
Why it matters
Migration planning visibility matters because cloud application migration succeeds or fails on sequencing and dependencies you can explain to teams. If the plan is opaque, you’ll discover issues late during waves.
How to check
Ask the vendor to show how they represent the migration waves from start to finish, including prerequisites and sequencing. During the demo, pick two sample apps and trace how the tool links them to an execution order.
Cutover and rollback controls
Why it matters
Cutover and rollback controls matter because application downtime and data risk come from the last mile of switching traffic and writes. Tools that only “launch” without reversible steps force risky manual work.
How to check
Request a live walkthrough of a cutover workflow that includes a rollback path. Confirm what artifacts the tool records before switching, and what actions it automates if you reverse.
Data replication and sync handling
Why it matters
Data replication and sync handling matters because most migrations fail on mismatched timing between services and databases. The right tool makes lag and reconciliation visible so you can choose a controlled final sync window.
How to check
Ask how the tool handles ongoing changes during migration and during the final sync. In the demo, show a sample reconciliation view and how it signals readiness to proceed.
Application dependency mapping depth
Why it matters
Application dependency mapping depth matters because cloud application migration often breaks through hidden call paths and shared services. Better dependency views let you move the right set of apps together.
How to check
Pick one business workflow and ask the vendor to show the dependency graph they discover for it. Validate the result by comparing the graph to a small set of manually provided service endpoints or logs.
Automation API and extensibility
Why it matters
Automation API and extensibility matters because migration programs run across multiple teams and tooling. If the product can’t integrate through an API and automation surface, you end up with spreadsheets and handoffs.
How to check
Ask for an API reference and a sample script or workflow that triggers a migration step programmatically. Verify whether you can export status and feed it into your own orchestration and reporting.
RBAC and audit log for operators
Why it matters
RBAC and audit log for operators matters because migration actions are high-impact and often cross teams. Without role separation and traceability, you can’t prove who changed what during waves.
How to check
In the demo, create two roles with different permissions and attempt to run the same migration action as each. Then open an audit view for a completed run and confirm it records actor, timestamp, and the specific action.
Red flags
- Plans show execution steps but hide why apps are sequenced that way
- Cutover looks one-way with rollback described only as “manual”
- Data sync readiness is unclear or doesn’t surface lag and reconciliation details
Fit by situation
- If your team runs migrations in planned waves across many apps, prioritize Migration planning visibility.
- If you must minimize downtime and can’t accept risky reversals, prioritize Cutover and rollback controls.
- If your workloads keep changing during migration, prioritize Data replication and sync handling.
