It is part of the Cloud & IT Cert Prep learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Three Ways to Deploy the Cloud
IaaS, PaaS, and SaaS describe what you get. The deployment model describes where it lives and who can reach it: public, private, or hybrid cloud.
Public Cloud Defined
A public cloud is owned by a provider like Microsoft and shared by many customers. Smart logical isolation keeps your data private even on shared hardware. Azure is one.
Benefits and Limitations of Public Cloud
Public cloud perks: no upfront cost, instant scale, global reach, latest services. The catch: less hardware control and you trust the provider on security and compliance.
Private Cloud Defined
A private cloud is dedicated to one organisation — cloud tech, but single-tenant. Azure Stack Hub, for example, brings Azure into your own data centre.
Benefits and Limitations of Private Cloud
Private cloud gives maximum control and easier compliance, even air-gapped. The cost: heavy CapEx and limited scale. Common in defence, banking, and healthcare.
Hybrid Cloud Defined
A hybrid cloud mixes public and private (and on-prem), letting data and apps move between them. Tools like Azure Arc and VPN Gateway stitch it all together.
# Connect on-premises network to Azure via VPN Gateway
az network vnet-gateway create \
--name myVpnGateway \
--resource-group myRG \
--vnet myVNet \
--gateway-type Vpn \
--sku VpnGw1Common Hybrid Scenarios
Common hybrid uses: cloud bursting to Azure on a spike, gradual migration one app at a time, and keeping regulated data on-prem while serving the rest from the cloud.
Multi-Cloud: Beyond Hybrid
A multi-cloud setup uses two or more public providers at once. Hybrid mixes public with private; multi-cloud mixes providers. Azure Arc can govern AWS or GCP too.
Choosing a Deployment Model
Picking a deployment model? Strict data rules point to private or hybrid; max scale and low cost point to public; a gradual move from on-prem points to hybrid.
Azure's Role in Each Model
Azure plays in all three: a public cloud in Microsoft data centres, Stack Hub for private, and VPN Gateway or ExpressRoute to link your on-prem network securely.
Latency and Compliance Considerations
Two big factors in your choice: latency may push real-time work to private or edge, and compliance may require data to stay in one country or boundary.

Lesson Recap
Quick recap: public is shared infra with no CapEx, private is dedicated for max control, and hybrid blends both to meet rules and scale at once.
