Top Cloud Consulting & SI Companies

Cloud consulting and systems integration (SI) firms plan and carry out the move of applications and data to AWS, Azure or Google Cloud, then connect it to the systems a company still runs on premises. The work spans readiness assessments, landing zone design, migration waves, identity and access, cost governance, and the integration that keeps ERP, CRM and data platforms talking. IT directors hire them when a data center lease ends, when a merger leaves two estates to combine, or when cloud bills climb.

Compare the firms here on partner tier with your chosen hyperscaler, on reference migrations of similar size and regulatory load, on whether they hand back infrastructure as code, and on reviews that talk about cost after go-live.
