A fourth deployment model has begun to gain traction among organizations:
- Multi-cloud. This model leverages cloud computing services (storage, computing, and applications) from multiple cloud providers. A multi-cloud model relies on more than one public cloud provider, but it can also use a hybrid cloud. For example, a company can store sensitive data on its servers and use one public cloud provider for infrastructure-as-a-service (IaaS) and a second provider for software-as-a-service (SaaS).
So, how should you decide which cloud deployment model is right for your organization?
To determine the cloud computing deployment model that best suits your needs, you must evaluate your list of unique requirements. You shouldn’t have to compromise and pick one model, though. Many companies combine different models to access the varying benefits.
For example, public clouds might be cheaper, as they have no capital expenses. Private clouds, though, involve capital expenditures, but they are still cheaper than owning and maintaining on-premises infrastructure.
