Microsoft Azure is the second-largest cloud provider and the default choice for organizations already invested in the Microsoft ecosystem. Azure integrates deeply with Active Directory, Office 365, and Windows Server.
Core Services
Compute: Virtual Machines, App Service (PaaS), Azure Functions (serverless), AKS (managed Kubernetes).
Storage: Blob Storage (object), Managed Disks (block), Azure Files (SMB/NFS file shares).
Database: Azure SQL, Cosmos DB (multi-model NoSQL), Cache for Redis, Synapse Analytics.
Networking: Virtual Network, Front Door (CDN + WAF), ExpressRoute (dedicated connectivity).
Enterprise Integration
Azure’s strongest differentiator is seamless integration with existing Microsoft infrastructure:
- Azure Active Directory — single identity platform across cloud and on-premises
- Hybrid cloud with Azure Arc — manage on-premises, multi-cloud, and edge from one control plane
- Microsoft 365 integration — unified management for productivity and infrastructure
- GitHub integration — CI/CD pipelines, Codespaces, Copilot
Pricing
Similar structure to AWS: pay-as-you-go, reserved instances (1-3 year), and spot VMs. Azure Hybrid Benefit allows existing Windows Server and SQL Server licenses to reduce cloud costs.
