Understanding Multi-Cloud: Beyond Hybrid Cloud
It's crucial to distinguish multi-cloud from other cloud strategies:
- Single Cloud: Relying on one public cloud provider for all or most of your cloud needs.
- Hybrid Cloud: A combination of a public cloud and a private cloud (on-premise data center or dedicated private cloud). Data and applications can move between them.
- Multi-Cloud: The use of two or more public cloud providers. This can involve using different providers for different applications, or even for different components of the same application.
While a hybrid cloud often involves a multi-cloud component (e.g., private cloud + AWS + Azure), the defining characteristic of multi-cloud is the intentional use of multiple public cloud vendors.
Compelling Drivers Behind Multi-Cloud Adoption
The shift towards multi-cloud is driven by a confluence of strategic and operational factors:
1. Vendor Lock-in Avoidance
- Driver: Relying on a single cloud provider can lead to dependence on their specific technologies, pricing models, and service roadmaps. Switching providers later can be costly and complex.
