Overview
Deloitte Touche Tohmatsu Limited is the largest of the Big Four professional services networks by revenue, with reported FY2024 aggregate global revenues of US$67.2 billion and approximately 460,000 employees in more than 150 countries. The network is headquartered in London, United Kingdom, and led by global chief executive Joseph Ucuzoglu since 2023. Deloitte Consulting LLP, the US member firm, operates the largest national consulting practice in the network and is the principal entity that delivers cloud migration engagements in North America.
Cloud migration sits within Deloitte's Engineering, AI, and Data offering. The firm is a Premier consulting partner of AWS, a Microsoft Solutions Partner across all six designations, a Google Cloud Premier Partner, and an Oracle Cloud Service Expertise partner. Delivery uses Ascend, Deloitte's industry-aligned cloud platform pre-configured with reference data models for financial services, life sciences, government, and consumer products, plus an internal migration factory called CloudHive. The firm reports more than 70,000 cloud-certified practitioners globally and has executed multi-cloud migrations for organisations including the United States Department of Defense, US Internal Revenue Service, Unilever, and General Motors.
Deloitte is typically a fit for enterprises and large public sector bodies that need cloud migration delivered alongside risk, regulatory, audit, finance, or wider business transformation in a single integrated programme. The firm is rarely the cheapest option, can be slower to execute pure technical migrations than hyperscaler-specialist boutiques, and most low-complexity lift-and-shift programmes are better served by an India-headquartered systems integrator.

Strengths
- Strongest Big Four delivery in regulated and public sector cloud — federal, state and local, defence, healthcare, and central banks
- Integrated audit-aligned controls and regulatory expertise on the same engagement, reducing downstream remediation
- Ascend industry-cloud platforms accelerate target operating model design for banking, life sciences, and government workloads
- Strong programme governance and PMO discipline for complex multi-stakeholder migrations
- Top-tier partner across all four major hyperscalers, plus deep Oracle Cloud Infrastructure capability inherited from Deloitte's Oracle alliance
- Named a Leader in 2025 Gartner Magic Quadrant for Public Cloud IT Transformation Services and Forrester Wave for Cloud Migration
Limitations
- Rate cards are typically the highest among Big Four — 5 to 15% above Accenture at comparable seniority
- Engagement governance and matrix structure can slow technical decision making versus more nimble boutiques
- India-blended delivery is available but proportionally smaller than Accenture, TCS, Infosys, or Wipro
- Audit-firm independence rules constrain post-migration managed services for audit clients in some jurisdictions
- Member firm structure means delivery quality and rates vary between Deloitte US, UK, Germany, India, and Canada
- Less competitive on pure technical lift-and-shift where regulatory and operating-model overlay is not needed
