3. Connectivity Services (20-25%)

Hybrid connectivity bridges your on-premises infrastructure with Azure. Without reliable connections, your cloud investment becomes an isolated island—unreachable by the users and systems that need it most.

💡 First Principle: Hybrid connectivity solves the "two networks, one organization" problem. Whether you choose VPN (encrypted tunnels over the internet), ExpressRoute (dedicated private connections), or Virtual WAN (managed hub-and-spoke), the goal is the same: make Azure feel like an extension of your datacenter, not a separate environment.

What breaks without this:

• Remote workers can't access Azure-hosted applications
• On-premises servers can't reach Azure databases
• Disaster recovery fails because replication can't flow
• Compliance requirements for private connectivity go unmet
