Q

What is IaaS?

A

Contains the basic building blocks for cloud IT
and typically provide access to:
-networking features
-computers (virtual or on dedicated hardware)
-data storage space
This model provides the highest level of flexibility and management control over your IT resources and is
most similar to existing IT resources that many IT departments and developers are familiar with today

Q

What is the cloud deployment model?

A

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.

Q

What is the hybrid deployment model?

A

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.

Q

What is the on premises deployment model?

A

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 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.
