Cloud computing technology is based on three special cloud computing service models, which are popular, effective, flexible, and user-friendly. Therefore, the basic model of the cloud architecture is:
1. Infrastructure as a Service: Infrastructure benefits include computers, networks, storage, load balancing devices, and virtual machines. These hardware and software resources that serve end users can be expanded or contracted according to their needs.
2. Software as a Service: As the name suggests, this model includes software components like virtual desktops, various utility applications, content resource management, email, software, and more. 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 model, managed service providers help customers by providing a work platform, including runtime, databases, Web services, development tools, and operating systems, without the need for customers to manually allocate resources.
There are four deployment models for cloud computing, each with unique features 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 these services are free, and some are paid on an as-needed basis. This mode can only be accessed and used using the Internet. At the same time, this model is also 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 is dedicated to a certain enterprise, whether it is self-management or third-party management, whether it is responsible for own or third-party hosting, it does not matter. As long as there is no problem with the way you use it, you can bring significant help to your business. However, what this model faces is that the security problems such as correction and inspection require the company to be responsible for it. Otherwise, the problem can only bear the consequences itself. In addition, the entire system also needs to pay for purchase, construction and management. This cloud computing model can produce positive benefits in a very wide range. As can be seen from the name of the model, it can provide owners with services with sufficient advantages and functions.
3. Community Cloud: This model is built between multiple companies with similar goals in a specific group. They share a set of infrastructure, and the company seems to move forward together. The costs incurred are shared by them, so the cost savings that can be achieved are not very large. Members of the community cloud can log into the cloud to get information and use the app.
4. Hybrid Cloud: A hybrid cloud is a hybrid of two or more cloud computing modes, such as a mix of public and private clouds. They are independent of each other, but they are combined within the cloud to take advantage of the hybrid cloud computing models.
