How to Choose the Right Global Cloud Services
A practical selection framework matches the provider's delivery model to the program's technical complexity, governance needs, and integration depth.
Match the delivery model to the program scale and decision cadence
For enterprise programs that need repeatable execution, Accenture provides a Cloud First model built around migration factories and managed operations. Infosys uses a Cloud Migration Factory to deliver structured, repeatable enterprise migrations when multi-region consistency matters. For programs that can stall under heavy process, Wipro and Atos still deliver governance-led transitions, but they perform best when internal ownership and agile decision cadence are clearly defined.
Verify that security engineering and cloud governance are built into delivery
Deloitte delivers cloud risk and security aligned to enterprise governance controls across environments. Capgemini integrates cloud security engineering into delivery for governance and risk reduction during migration and modernization. IBM Consulting pairs security architecture and compliance controls with operating model design and managed operations.
Confirm hybrid integration capability if on-prem connectivity is required

Common Mistakes to Avoid
Selection errors show up when governance depth, integration requirements, or delivery structure are mismatched to the program’s actual constraints.
Choosing a vendor that treats cloud security and governance as a side activity
Deloitte, IBM Consulting, and Capgemini embed cloud risk and security delivery into the program through governance alignment, security architecture, and security engineering integrated with delivery. Accenture also integrates cloud security and governance practices for regulated clients so security is part of engineering and run models rather than a separate workstream.
Underestimating the impact of heavy enterprise delivery structures on small teams
Accenture, Deloitte, Capgemini, and NTT DATA can slow decisions when delivery scope is large and stakeholder alignment is hard to achieve. Infosys and Tata Consultancy Services mitigate this risk by using factory-based or standardized pipeline delivery patterns that can keep migration execution structured.
Ignoring hybrid integration requirements until late in the migration lifecycle
CGI and NTT DATA are built around hybrid integration and enterprise systems connectivity, so selecting a provider without that focus can increase coordination overhead later. CGI keeps enterprise systems tightly connected during adoption, while NTT DATA delivers cloud migration and modernization paired with managed operations under enterprise integration governance.
Failing to plan for an operating model change needed for post-launch stability
Accenture notes operating model changes can require significant client process alignment, which becomes a delivery risk if internal ownership is not established. Atos and Wipro also depend on clear target-state ownership so migration waves and managed operations transitions land cleanly.
