The world's new way for more web software development is cloud-based API applications. Governments and private sector organizations are trying to streamline their operations as they expand their footprint. New technologies are already enabling infrastructure savings like never before. Just as importantly, a number of new technological innovations are now helping us reimagine the efficiency and optimization of infrastructure and services in general. The greatest impact is seen in the area of ​​smart cities, which are transforming the delivery of management, energy and utility services. Software and website developers save a lot of time by leveraging various cloud services and focus their attention on new business logic solutions. Centralized, intelligent cloud services automatically improve app functionality or performance based on data, not unlike Amazon for making recommendations based on previous purchases or ad tech companies for optimizing retargeting. Cloud application architecture bears some resemblance to SDN. , where a centralized intelligent element, often plays the role of analyzing data from many endpoints and modifying the behavior of the endpoints. Distributing application logic across many centralized cloud services enables more automated and intelligent applications. And the timing couldn't be better. However, as they mature, more and more of these companies are deploying intelligence and automation at your service. This will allow you to use the SDN qualities of its architecture to analyze data from all applications that run these services and then modify the application to improve performance or change the behavior of...... middle of paper. ... .s and end nodes change behavior. Distributed across many cloud service application logics, enabling more centralized and intelligent automation applications. The back of the cloud computing system, a variety of computers, servers and data storage systems to create the cloud computing services. I start reading these articles one by one. This article taught the basics of cloud computing to the user who is not familiar with the cloud computing system. The author of this article attempts to cover all aspects of cloud computing. The author attempts to innovatively discuss all the logical, front-end and back-end aspects of this latest technology. Works Cited The Little Book of Cloud Computing. (2011).
