Types of cloud computing
Cloud computing provides developers and IT departments with the ability to focus on what matters most and avoid undifferentiated work such as procurement, maintenance, and capacity planning. As cloud computing has grown in popularity, several different models and deployment strategies have emerged to help meet specific needs of different users. Each type provides you with different levels of control, flexibility, and management.
Deployment models
Cloud
A cloud-based application is fully deployed in the cloud and all parts of the application
run in the cloud. Applications in the cloud have either been created in the cloud or have been
migrated from an existing infrastructure to take advantage of the benefits of cloud computing
Private cloud (on-premises)
The deployment of resources on-premises, using virtualization and resource management
tools, is sometimes called the private cloud. On-premises
deployment doesn’t provide many of the benefits of cloud computing but it is sometimes sought for
its ability to provide dedicated resources. In most cases, this deployment model is the same as
legacy IT infrastructure while using application management and virtualization technologies to
try and increase resource utilization. For more information on how AWS can help, refer to

Hybrid
A hybrid deployment is a way to connect infrastructure and applications between cloud-based
resources and existing resources that are not located in the cloud. The most common method of
hybrid deployment is between the cloud and existing on-premises infrastructure to extend, and
grow, an organization's infrastructure into the cloud while connecting cloud resources to the
internal system. For more information on how AWS can help you with your hybrid deployment,
