Cloud Delivery and Hosting Models - Deploying and Managing a Cloud Infrastructure - page 159

The following kinds of organizations are suited for a full private cloud deployment:

Banks that have an on-premises cloud computing infrastructure that delivers software,
computing, storage, security, and backup

■

Hospitals and health service providers, which have strict regulatory requirements and
implement private cloud and virtualization solutions within their IT facilities

■

Military services/armed forces that use secure and protected cloud computing technol-
ogies to automate their processes, store data, and share strategic knowledge

■

Government institutions that require massive pools of dedicated computing

Semi-private Cloud Deployment Model

This deployment model is rather confusing because it is neither entirely public nor entirely
private and yet it's not hybrid either. It is a type of cloud that is provisioned from a cloud
service provider that offers an entirely dedicated cloud environment to a client, one that's
separate from and not shared with other semi-private cloud customers. In short, it is a non-
multitenant cloud service offered by a public cloud service provider that is delivered over pub-
lic channels but contains all of the characteristics of a private cloud (including security and
control) but is still considered to be off-premises. A dedicated server is a common example of
a semi-private cloud that runs entirely for a single customer. It is not part of a public cloud
environment, is accessed over a secure VPN or web connection, and provides enhanced levels
of control of the cloud environment at the customer's side. Organizations looking to leverage
the power of a secure and exclusive cloud in a cost-effective way are well suited for this type
of cloud deployment model.
The following types of organizations are suited for a semi-private cloud deployment:
■ Application developers (mobile/web/SaaS) that can utilize a dedicated server to
develop, test, and deploy applications and services
■ Banks that deploy and deliver external or partner banking applications through an
external cloud
■ E-commerce stores and web portals hosted and managed within a private cloud envi-
ronment located on a provider's premises
Another, similar deployment is co-location, where the customer deploys and houses
servers and other computing resources within the cloud service facility of a provider. The
service provider maintains, manages, and operates the servers on the customer's behalf and
delivers a cloud environment that can be accessed from anywhere over the public Internet.
This is a good fit for organizations that are looking for a private cloud solution but have
no means of housing a hardware infrastructure and do not want on-premises IT staff and
other resources to operate the cloud environment.
