There are three cloud computing service models, namely: infrastructure as a service (IasS), Platform as a Service (PasS), software as a service (SaaS) these types of models, each service mode is reduced by its very nature resource abstraction consumers build and deploy complexity of the system. In the traditional IDC room, the management team must be responsible for all construction and operation and maintenance activities.
IT Tuanhui service installation and administration servers must be hands-on, and then step by step to operating systems, firmware, applications, databases, etc. for maintenance, if security vulnerabilities to quickly patch. Relatively speaking, the use of cloud services, such as on the use of the new Core cloud can simplify complex issues, we can easily manage the server through different levels of abstraction, so that the time and energy into business on their own proprietary .

What IasS that?
There is a very important concept Infrastructure as a Service (IasS), its essence is the physical center of the device and the data center (disk, server, network) to maintain and manage in the cloud, and then put it into a series of abstract services available , can allow users to use a web page or other sub-code form for maintenance management and automated deployment.
So developers only need to design and develop applications, system operation and maintenance personnel only need to focus on data security, server security, and promptly marked the official patch can be! It no longer has the infrastructure and equipment of dedicated ......
IasS how to use?
IasS services that people can access through a virtual infrastructure in a few minutes to complete the landing page or by calling the API resource deployment and management of end run.
Like water and electricity as a public service, a virtual infrastructure is quantifiable service, only time will turn on and use billing! Closed when there is no cost.
Because of its specificity, allowing users to focus on their specific business, the ultimate goal is to create profit.
Currently the market offers many excellent infrastructure operators, like Google, Amazon, the new Core cloud can be selected. This article will not start because of space, everyone eyes of the beholder wise see wisdom, you can select the most suitable own!
