Deployment models for cloud computing

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.

For example, a company might create an application consisting of virtual servers, databases, and networking components that are fully based in the cloud.

on-premises deployment

• Deploy resources by using virtualization and resource management tools.
• Increase resource utilization by using application management and virtualization technologies.
  On-premises deployment is also known as a private cloud deployment. In this model, resources are deployed on 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.
  In a hybrid deployment, cloud-based resources are connected to on-premises infrastructure. You might want to use this approach in a number of situations. For example, you have legacy applications that are better maintained on premises, or government regulations require your business to keep certain records on premises.
