Cloud deployment models

1.1 Deployment

The three different service models can be deployed for a customer in various way varying from the public internet to a private data center. The Figure 4 shows the different deployment strategies which are detailed in the following paragraphs.

Public

is a deployment strategy which uses the publicly available internet to deliver the services to the users. A great advantage of this deployment type is that the services is available for any internet connection, an down side however is the security. The cloud services like Gmail and Azure are services provided trough the public cloud (Armbrust, et al., 2009).

Private

This deployment strategy can be compared with the traditional in-house hosting of an service, however it uses the technologies on which cloud computing is based such as virtualization to provide advantages to the organization(Armbrust, et al., 2009).

Community

A community cloud is a bit like a private cloud however the cloud is share among a community of organizations. This is done to divide the costs and risks of running a own cloud. These cloud can be found in share service centers which service multiple organizations (Buyya, 2009).

Hybrid

A hybrid cloud is a cloud computing environment in which an organization provides and manages some resources in-house and has others provided externally. For example, an organization might use a public cloud service, such as Amazon’s Elastic Compute Cloud (EC2) for general computing but store customer data within its own data center (Cole, 2009).
