For most IT teams, the best public cloud choices are:
1. **Microsoft Azure**
Best for: **Windows environments, Active Directory, Microsoft 365, hybrid IT**
Key products: **Azure Virtual Machines, Azure Arc, Azure Backup, Azure Monitor, Azure AD (Entra ID)**

- **Data-heavy or Kubernetes-first:** **GCP**
### Strong enterprise add-ons
- **Oracle Cloud Infrastructure (OCI)**: good for Oracle databases and lower-cost compute
- **IBM Cloud**: niche, mainly for regulated or legacy enterprise use cases
If you want, I can also rank them for **cost**, **security**, **hybrid management**, or **Windows/VMware migration**.
