Computational technology develops along with the development of civilization and is an important part of social civilization. China's abacus is the earliest computing tool. After 1500 years, the French invented the eight-digit adder, and the Germans invented the modern calculator until the advent of the first Turing computer ENIAC (computer name), announcing the advent of the era of electronic computing. Cloud computing is also a time coordinate for the development of computing processes. It is not only the development of computing technology, but also the result of the overall promotion of industry operations. At present, cloud computing has moved from concept to landing stage, and the changes it brings will have a huge impact on the production and lifestyle of the whole society, thus promoting the overall development of society.
How to use the cloud computing platform----personal useCloud computing refers to a pattern in which applications and saved files are stored on a remote server. You can access these applications and files over your network (in many cases the Internet) with your own PC.
Cloud computing is not really a new concept. Due to the increasing popularity of computer networks, especially the Internet, and the growing popularity of "connected" broadband connections, this old concept has once again received much attention.
There are many ways for cloud computing to use it, such as:
1. All important data is stored on the network;
2, such as using dropbox to store documents;
3. Use applications that can automatically synchronize data, such as browsers;
There are many cloud services, such as network disks, cloud platforms, and so on. Gleasy Cloud combines cloud storage, cloud mailbox, OA office, and cloud IM.
First of all, in the design concept, we must shift from the previous concept of relying on hardware to ensure reliability to the design concept of failure. The so-called failure is to assume that the hardware is unreliable, through the architectural and technical design to ensure high availability and high reliability of the business. For example, in terms of storage, the traditional way is to achieve data reliability through hardware redundancy mechanisms such as RAID, but in the object storage, the data is highly reliable through multiple copies of the distributed mechanism; In the traditional way, the available time is guaranteed by high-reliability hardware. However, in the world of cloud computing, the high availability of the guaranteed service is achieved through a sophisticated monitoring mechanism and a fast instance restart. This concept is very important for cloud computing, because it can get rid of the dependence of cloud computing platform on hardware reliability, make it possible to use cheap hardware and obtain high availability and high reliability, which can reduce the overall cost.
The second is to transform the application into a loosely coupled structure such as SOA. This allows your application to get rid of the reliance on the operating system, hardware, etc., allowing you to deploy and use it freely and quickly on heterogeneous platforms, enhancing the agility of your organization and allowing your application to scale. It's scalable and allows you to quickly publish your app in an iterative manner. Here is a very important concept is API (ApplicaTIonProgrammingInterface), the use of API to unify the format of the data, to achieve communication with another module, call resources and other operations, is also an important feature of the loosely coupled architecture. Currently popular are RESTful API interfaces, such as API interface specifications in JSON and XML formats.
Again, consider turning serial work into parallel work. We all know that more and more data is generated in the enterprise, which is more and more demanding for enterprise data processing capabilities. So how to improve the processing power? Traditional data is generally serialized, and the performance of serial work depends mainly on the level of hardware processing power. In this case, the hardware limitations can not be removed. The solution is to convert most serial work into parallel work. The unit throughput is reduced, enabling ordinary devices to process data quickly. This cocoa can be achieved by using tools such as Hadoop.
There is also a variety of storage schemes to store different data. For example, block storage is used to store data for relational databases, and object storage is used to store rich media data (images, video, etc.), which improves overall performance and efficiency, and allows for better optimization of cost structures.
Enterprises also need to consider the connection between the private cloud platform and the public cloud platform, which is crucial for the future scalability and portfolio economy of your private cloud platform, even if your platform can be easily modified (such as adding Modules) It's even better to provide cloud computing services to your partners or customers and even expand into the industry's public cloud.
How to use cloud computing platform----government useGovernment needs. In 2008, Amazon Cloud Computing received an urgent subcontracting mission. While the National Archives of the United States publicly disclosed Hillary’s schedule of the White House from 1993 to 2001, it must upload the information to the Internet at the same time for public access. This is because the reporters’ group has repeatedly submitted to the National Assembly for information disclosure according to the Freedom of Information Act, which has great political supervision significance. The first object to receive this task is the Washington Post. In the face of a large number of unsearchable low-quality PDF files, it must be formatted for Internet access for public inspection. With the data processing capability of the newspaper, only one page takes 30 minutes. . In conjunction with the Washington Post's subcontracting business, Amazon uses 200 virtual servers on the Iaas platform of EC2 (Cloud Computing Service) to complete the task in 9 hours, with a single page processing time of only 1 minute. The Washington Post only pays $144.62. If there is no cloud computing, it will cost 1407 hours of server runtime, and the economic impact of the economy and the image of the country will be enormous.
