The difference between cloud computing software and traditional software

Cloud computing technology has completely changed the consumption mode and service mode of the traditional IT industry. Consumers changed from "buying software and hardware products" to "buying IT services", and obtained and used services through the Internet, which greatly improved IT efficiency and agility. Traditional software is a document-driven process, which divides the whole software development process into several stages in sequence, and each stage must complete all the specified tasks (documents) before entering the next stage. If all the system requirements specifications must be completed before entering the outline design stage, coding must be carried out after the system design is completed. The essential difference between cloud computing products and traditional software products lies in integrity. Traditional products only consider local applications, for example, smart cities only consider local applications in a certain city, regardless of the relationship with other cities. Real cloud computing products are designed at the national level. The product can be used in small areas and large areas. Government managers in different regions can easily understand the information they need to obtain authorization, and provide decision-making reference data for them to design and adjust the industrial structure.
