📖 What is Hybrid Cloud?
Hybrid cloud integrates on-premises infrastructure, private clouds, and public cloud services, enabling data and application portability. This model allows organizations to leverage the scalability of the public cloud while maintaining control over sensitive data and legacy systems within a private environment.
"The exam emphasizes the practical benefits of hybrid cloud, such as phased migration and disaster recovery. Understand the distinction between hybrid, public, and private cloud models. Be prepared to identify scenarios where hybrid is the optimal solution, considering factors like compliance and cost."

🔑 What are the Key Concepts of Hybrid Cloud?
- ▸ Hybrid cloud allows organizations to extend their datacenter to the cloud, maintaining control over sensitive data while utilizing cloud resources.
- ▸ Key benefits include phased cloud adoption, enabling organizations to migrate workloads gradually and minimize disruption.
- ▸ Hybrid models support disaster recovery scenarios by replicating on-premises data to the cloud for business continuity.
- ▸ Connectivity between on-premises and Azure is often established using VPN gateways or ExpressRoute for secure and reliable access.
- ▸ Understanding compliance requirements is crucial; hybrid cloud allows keeping regulated data on-premises while leveraging cloud for other workloads.
🎯 How does Hybrid Cloud appear on the AZ-900 Exam?
You may be asked to identify the best cloud model for a company needing to retain full control over customer Personally Identifiable Information (PII) due to strict regulatory requirements.
A scenario might describe a business wanting to test a new application with minimal upfront investment – determine how hybrid cloud facilitates this through bursting.
Expect questions about choosing between VPN Gateway and ExpressRoute based on bandwidth needs, latency requirements, and cost considerations for a hybrid setup.
❓ Frequently Asked Questions
When would a company choose hybrid cloud *over* a full public cloud migration?
Hybrid is ideal when data residency, compliance, or legacy application dependencies prevent a complete move to the public cloud. It offers a balance of control and scalability.
What's the difference between hybrid cloud and multi-cloud?
Hybrid cloud specifically connects on-premises infrastructure to *one* public cloud. Multi-cloud uses multiple public clouds, potentially without on-premises integration.
How does Azure Arc fit into a hybrid cloud strategy?
Azure Arc extends Azure management capabilities to on-premises servers and other clouds, allowing centralized governance and policy enforcement across your entire hybrid environment.
