What are cloud computing cloud services?

Cloud computing: By distributing computing over a large number of distributed computers rather than local computers or remote servers, enterprise data centers will operate more like the Internet. This enables enterprises to switch resources to needed applications and access computers and storage systems on demand.

This type of service mobilizes various resources in the network to serve users. (Personally, I think it's a bit like BT). Unity is strength! This kind of service will be the mainstream in the future.

The business model of cloud services is to multiply a large number of start-up companies to provide rich personalized products to meet the growing personalized needs in the market. Its method of reproduction is to provide start-up companies with a complete set of services including funding, promotion, payment, logistics, and customer service, and make its own operating capabilities available to outsiders for on-demand use like water and electricity.

The premise for the birth of cloud services is that the Internet breaks down geographical divisions to form a unified market, and it becomes profitable to provide products for personalized needs. The objective effect is: to reduce the cost of starting a business to a minimum, entrepreneurs will only focus on core aspects such as creativity, and operations and management will no longer be important. Small companies began to challenge large companies and subvert the industrial civilization of "win at scale". Our society and culture will be more independent and free.

A major change brought about by cloud services is the shift from device-centric to information-centric. Devices, including applications, are just passersby that come and go (who can read a floppy disk now?), while information and people's investment in information are assets that must be retained for a long time (more people change their mobile phones than twice a year) Gone, and the most significant loss caused by the loss of the mobile phone is probably the lack of backup of the address book). So as mentioned above, no matter how novel it is, even the currently quite expensive front-end hardware equipment will become obsolete, and some will even become obsolete quickly and become worthless! What is not easy to become obsolete on the cloud? Information! Not only is it not obsolete, Much information must be preserved for a long time and becomes more valuable the longer it lasts.

In the future, everyone on the cloud will have a lifelong personal data body. Such personal data will not be tied to any kind of machine and will become invalid as the machine expires. How to achieve such an attribute? Virtualization technology plays a role again (virtualization technology will also play an important role below)! Note that in this section virtualization is for the front-end technology.

One of the advantages of cloud development is economies of scale. By leveraging the infrastructure provided by a cloud computing provider, developers can deliver better, cheaper and more reliable applications than if they were developed within a single enterprise. If needed, applications can leverage the full resources of the cloud without requiring companies to invest in similar physical resources.

Cloud storage is a new concept extended and developed from the concept of cloud computing. It refers to the use of cluster applications, grid technology or distributed file systems to integrate a large number of data in the network. Various types of storage devices are brought together to work together through application software to form a system that provides external data storage and business access functions. When the core of cloud computing system computing and processing is the storage and management of large amounts of data, a large number of storage devices need to be configured in the cloud computing system. Then the cloud computing system becomes a cloud storage system, so cloud storage is a data storage system. and management as the core cloud computing system.
