Deployment models for cloud computing

When selecting a cloud strategy, a company must consider why would they want a cloud AWS solution.

There are three cloud comping deployment models:

Cloud-based deployment

• Run all parts of the application in the cloud.
• Migrate existing applications to the cloud.
• Design and build new applications in the cloud.

On-premises deployment // Private cloud deployment

• Deploy resources by using virtualization and resource management tools.
• Increase resource utilization by using application management and virtualization technologies.

Resources are fully kept in-premises by using virtualization and resource management tools.

Hybrid deployment

• Connect cloud-based resources to on-premises infrastructure.
• Integrate cloud-based resources with legacy IT applications.

If there is a need to keep some application in-premises due to the impossibility of migration or privacy concerns, a hybrid approach may be better to met the requirements of the applications and get the benefits of the cloud.
