After more than ten years development, cloud computing has become an irresistible trend of technology, gradually deep into all walks of life, different sizes of organizations, to help users with lower operating costs to improve efficiency of IT service,
Simply put, cloud computing is the delivery to users via the Internet servers, storage, database, network, software and the analysis of computing resources, such as providing these resources is called cloud providers, they will provide resources to meet the needs of users, and according to the actual usage rate,
Why do you want to use this model? Can use a simple analogy to understand:
The normal operation of enterprises cannot leave the tap water and electricity, but unless you have special requirements, otherwise, most companies will not themselves construction water plant and power plants, but will buy from the corresponding suppliers, enterprises need to consider the construction and maintenance of related infrastructure, also don't need to consider the size, just connect piping and wiring, can be obtained from suppliers a steady stream of water and electricity, and you just need to pay according to the dosage,
With the help of cloud computing, computing resources and it can be delivered to the enterprise, whether computing storage network basic skills, such as or complete system or solution, only need to apply for opening can be obtained from a cloud provider all the resources you need, also don't need to consider in order to obtain these resources need how many servers or storage devices, more do not need to consider the maintenance and management of the hardware, opened the box, according to the amount paid, also very convenient,
So cloud computing the model has been obtained from start-ups to large multinational companies, the favour of different users, basically, we choose this technology is mainly from the following six reasons:
? Expenses: without one-time pay large sums of money to buy the server hardware and software, later also don't need to undertake the management and maintenance of the human cost, such as continuous open cloud services can obtain the needed resources, immediately use how long, how hard the, will pay how many money, the cost is only related to construction infrastructure the tradition of fraction,
? Speed: traditional way to launch new system, usually need to experience of redundancy planning, application, approval, purchase, deployment, management, and other processes, the process may take several weeks or even months time, and in the case of using cloud computing services, little mouse, and at any time at any time need to allocate huge computational resources within several minutes, giving companies very big flexibility, and eliminate the stress of capacity planning,
? Global scale: elastic extension is one of the biggest advantage of cloud computing services, the user may apply according to the demand for the corresponding amount of resources (such as number of CPU cores, storage capacity, network bandwidth), and changes in demand at any time to increase or decrease the resource capacity, capacity when busy, when idle capacity, to help enterprises more cost-effective way to meet changing needs,
? Efficiency: the cloud of the underlying hardware maintenance and management work is responsible by the cloud providers, users do not need to consider these problems, so more energy can be used for their business,
? Performance: the scale benefits of cloud computing can also allow the user to further gain performance advantages, such as scattered data center can provide service for the user, to the nearest reduce network delay, improve access to experience; The latest hardware facilities and professional maintenance and performance optimization, to ensure that each user can fully exert all the potential of cloud services,
? Reliability: cloud service providers usually multiple data centers worldwide to provide services, thus it can be used multiple redundant sites for image data processing, to take this at a lower cost and easier way to provide the data backup and disaster recovery and business continuity,

Weight of cloud computing is to change the rules of many traditional industries, and improve the production efficiency of a sword, but the primary energy sources such as oil and natural gas and coal industry still needs to be developed, if you can put the data information into the industry, believe that will bring musty classic industry to glow the vitality of the New Year!CodePudding user response:
Use tap water and electricity companies metaphor is indeed very in place!
