Three service modes and four deployment models for cloud computing

Cloud computing technology is based on 3 kinds of special cloud computing service models, which are popular, effective, flexible, user-friendly and so on. Therefore, the basic pattern of the cloud architecture is:

1, infrastructure services: Infrastructure amenities include computers, networks, storage, load balancing devices, virtual machines. These software and hardware resources that serve the end-user can be extended or contracted according to their requirements.

2, Software as a service: As the name suggests, this model includes similar virtual desktops, a variety of practical applications, content resource management, e-mail, software and other software components. In this model, cloud service providers are responsible for installing, managing, and operating various software, while customers log in and use them through the cloud.

3, platform as a service: In this mode, the hosting service provider helps customers by providing a working platform, including execution time, databases, Web services, development tools, and operating systems, without the need for the customer to manually allocate resources.

Cloud computing has four deployment models, each with unique capabilities to meet different user requirements.

1. Public cloud: In this mode, applications, resources, storage, and other services are provided to users by cloud service providers, most of which are free, and partly on demand, which can only be accessed and used using the Internet. At the same time, this model is more secure in terms of private information and data protection. This deployment model typically provides scalable cloud services and can be set up efficiently.

2, Private cloud: This cloud infrastructure for a particular enterprise services, whether it is the management of their own or third party management, their own responsibility or third-party hosting, it does not matter. As long as the use of the way there is no problem, can bring significant help to the enterprise. However, this model is faced with, corrective, inspection and other security issues need to be responsible for the enterprise, otherwise, in addition to the problem can only bear their own consequences, in addition, the whole system also need their own money to buy, build and manage. This model of cloud computing can be very extensive to produce positive benefits, from the name of the model can also be seen, it can provide the owner with full advantage and functionality of the service.

3, Community Cloud: This model is based on a specific group of companies with similar goals, they share a set of infrastructure, enterprises are also like to move forward together. The resulting costs are shared by them, so the cost savings achieved are not very large. Members of the community cloud can access information and use applications in clouds.

4. Hybrid Cloud: A hybrid cloud is a hybrid of two or more cloud computing models, such as a public cloud and a private cloud mix. They are independent of each other, but they are combined in the interior of the cloud to give play to the advantages of the various cloud computing models that are mixed.
