What is the difference between the IT architecture of cloud computing mode and the traditional IT architecture?

1. Cloud computing architecture: This layer of cloud computing architecture in most data centers is mainly used to show the content and service experience required by users in a friendly way, and will make use of various services provided by the middleware layer below.

2. Traditional architecture: refers to a series of corresponding abstract patterns, which can provide corresponding guidance for all aspects of designing large-scale software systems.

Second, the characteristics are different.

1. Cloud computing architecture: Cloud architecture is divided into three levels: infrastructure layer, platform layer and software service layer.

2. Traditional architecture: The objects described in the software architecture are directly composed of system abstract components. Connecting the components of the system is to describe the communication between components clearly and in detail.

Third, the advantages are different.

1. Cloud computing architecture: a software application mode that provides software services through the Internet. In this mode, users don't need to spend a lot of money on the construction of hardware, software and development teams, but only need to pay a certain rental fee.

2. Traditional architecture: it provides a high-level abstraction of structure, behavior and attributes for software systems, which consists of component descriptions, component interactions, patterns that guide component integration and constraints of these patterns.
