# Hybrid Cloud Benefits and Use Cases > Chapter 50 of the Courseiva AZ-900 curriculum — https://courseiva.com/learn/az-900/hybrid-cloud-benefits **Official objective:** 1.3 — Cloud Concepts ## Introduction This chapter covers the practical benefits and common use cases of hybrid cloud, building on the deployment models chapter with a sharper focus on why organizations specifically choose this approach. AZ-900 tests this under objective 1.3. ## Keeping One Foot in Each World, Deliberately Some businesses keep a physical storefront while also selling online — not out of indecision, but because each channel serves a specific purpose the other doesn't fully cover. A hybrid cloud approach works similarly: an organization deliberately keeps some infrastructure on-premises while extending into the public cloud, because each environment serves specific needs the other doesn't fully address on its own. ## Core explanation ### Why organizations choose hybrid cloud Organizations often adopt a hybrid cloud approach for reasons like regulatory or data-residency requirements affecting specific workloads, existing infrastructure investments they aren't ready to fully retire, or specific performance needs that are better served by keeping certain workloads on-premises. ### Common hybrid cloud use cases - **Gradual migration**: extending into the cloud incrementally, rather than migrating everything at once. - **Regulatory compliance**: keeping specific regulated data on-premises while using the public cloud for other workloads. - **Burst capacity**: using the public cloud to handle temporary demand spikes beyond what on-premises infrastructure can support, while keeping steady-state workloads on-premises. - **Disaster recovery**: using the public cloud as a backup or recovery target for on-premises workloads. ### The connectivity foundation Hybrid cloud depends on reliable, secure connectivity between on-premises infrastructure and the public cloud — this is where services like VPN Gateway and ExpressRoute (covered in an earlier chapter) become directly relevant, providing that connection. ### Hybrid cloud is a deliberate strategy, not a temporary state While hybrid cloud is sometimes a step during a longer migration journey, for many organizations it's a deliberate, long-term strategy driven by specific, ongoing requirements — not just a temporary phase on the way to a fully public cloud environment. ## Real-world context A healthcare organization keeps patient records on-premises to meet strict regulatory requirements, while using the public cloud for less sensitive workloads like its public-facing website — a deliberate hybrid strategy driven by ongoing compliance needs, not a temporary phase toward eventually moving everything to the cloud. ## Exam focus Objective 1.3 expects candidates to understand common reasons organizations choose hybrid cloud and recognize it as a legitimate, often long-term strategy, not just a temporary migration phase. A common wrong answer is assuming hybrid cloud is always just a stepping stone toward eventually moving everything to the public cloud — for many organizations, it's a deliberate, ongoing strategy driven by specific, lasting requirements. Stable terms: **hybrid cloud**. Memory trick: hybrid cloud is often a deliberate choice, not just a temporary transition — driven by specific needs like regulation, existing investment, or particular performance requirements. ## Step by step 1. **Identify workloads with specific requirements** — Determine which workloads have requirements (regulatory, performance, or otherwise) that specifically call for remaining on-premises. 2. **Keep those workloads on-premises** — Workloads with those specific requirements remain in a private, on-premises environment. 3. **Extend other workloads into the public cloud** — Workloads without those specific constraints can take advantage of the public cloud's scalability and other benefits. 4. **Establish reliable connectivity between the two** — A secure, reliable connection (via VPN Gateway or ExpressRoute) links the on-premises and cloud environments together. ## Common misconceptions - **Misconception:** Hybrid cloud is always just a temporary phase before fully moving to the public cloud. **Reality:** For many organizations, hybrid cloud is a deliberate, long-term strategy driven by ongoing requirements like regulation or specific performance needs, not just a transitional step. ## Key takeaways - Organizations choose hybrid cloud for reasons like regulatory requirements, existing infrastructure investments, burst capacity needs, or disaster recovery. - Hybrid cloud depends on reliable, secure connectivity between on-premises infrastructure and the public cloud. - Hybrid cloud is often a deliberate, long-term strategy, not simply a temporary phase toward full public cloud adoption. ## FAQ **Why do organizations choose hybrid cloud?** Common reasons include regulatory or data-residency requirements for specific workloads, existing on-premises infrastructure investments, needing extra capacity for demand spikes, and using the cloud for disaster recovery — while keeping other workloads on-premises for specific reasons. **Is hybrid cloud always a temporary step toward full cloud adoption?** Not necessarily — for many organizations, it's a deliberate, ongoing strategy driven by lasting requirements, rather than just a temporary phase on the way to eventually moving everything to the public cloud. --- Interactive version with quiz and diagrams: https://courseiva.com/learn/az-900/hybrid-cloud-benefits
