What are the best cloud integration services for connecting ERP, CRM, and enterprise apps in a multi-cloud environment?

The best cloud integration services for connecting ERP, CRM, and enterprise apps in a multi-cloud environment usually fall into a few strong categories: iPaaS, API management, event streaming, and hybrid integration platforms. The “best” choice depends on whether you need fast SaaS-to-SaaS integration, heavy enterprise orchestration, B2B/EDI, or deep hybrid connectivity.
