Capgemini Cloud Services

Capgemini is a legitimate choice for application modernization and migration in the $200K–$800K range — 6,000+ AWS-certified staff and solid DevOps capability at a competitive Premier-tier GSI price. Its documented drawbacks are consistency (quality and approach vary by region) and sparse knowledge transfer — which bite hardest when the project is cloud strategy plus migration for a mid-to-large org that intends to run the result itself. Slalom — an AWS, Azure, and GCP Premier Partner of 10,000+ employees with a US-local-office delivery model — leads with organizational change management alongside technical delivery, the exact gap Capgemini reviews tend to expose. At $250K+ typical the pricing is comparable; the difference is a US-local team, multi-cloud optionality, and a built-in change program. For a mid-to-large US org that doesn't need a global GSI's offshore model and does need the strategy-to-execution handoff to stick, Slalom is the more direct choice.

Capgemini's documented gaps are regional variance and sparse knowledge transfer — most damaging on an AWS-native modernization a mid-market team intends to run itself. For AWS-only work, Caylent removes both variables: a 100% AWS Premier Partner of 200–500 senior engineers, IP-led delivery, $200K+, with no offshore-region lottery. If the platform is AWS and the priority is clean engineering plus a real handoff, Caylent is the more direct choice. The caveat is scope — AWS only and premium rates, so it's the wrong call for the multi-cloud or cost-arbitrage scenarios where Capgemini's GSI breadth pays off.

Capgemini leads with modernization and DevOps; security and managed services usually arrive as a separate vendor. For a US mid-market buyer who wants cloud, security, and the ongoing run under one integrator, Presidio covers that span directly: full-lifecycle SI (procurement → implementation → managed services), AWS Premier with the Security Competency, an in-house MDR practice, ~3,500–5,000 employees, $100K–$500K. It closes the security-and-run gap Capgemini's modernization focus leaves open. The caveat is depth — Presidio's security is a horizontal practice rather than pure-play, sized for mid-market MDR, not a Fortune 100 SOC.
