Cloud Computing Technology

Description

As the world's leading provider of ICT (information and communication technology) infrastructure and intelligence terminals, Huawei's products are already available in a number of areas, including connectivity, security, wireless, storage, cloud computing, intelligent computing, and artificial intelligence. The development of computing technology, especially Internet technology, has given birth to cloud computing technology. Cloud computing technology is considered a major revolution in information technology. It provides computing resources, storage resources, and all kinds of resources to users in the form of services through the network, changing the pattern of direct exclusive use of physical resources in traditional information technology architecture, and providing users with high reliability, high scalability, and low-cost on-demand services. This open access book introduces cloud computing and related technologies from the concept, technology, and architecture of cloud computing, combined with typical application cases of cloud; provides students with a more complete knowledge framework in the field of cloud computing; and lays the foundation for future research, development, and further study in cloud computing, big data, and other related fields.
