Zhang Peng: The nature of cloud computing is Internet applications

Complete cloud computing is an entire dynamic computing system, it consists of a large number of computer clusters, providing a managed application environment, dynamic deployment, dynamic allocation/redistribution of computing resources, real-time monitoring of resource usage-its scheduling is based on cloud storage, that is, the scheduling of computing tasks to run data storage nodes.

It delivers high reliability and high availability in a redundant way (cluster computing, data redundancy, and distributed storage), and can be done with low cost by using a low matching machine to replace the performance of supercomputers with task decomposition and clustering.

The technologies and capabilities provided by cloud computing are platforms and tools that can only be applied through the development of solutions to enable customers to pay for the transformation of storage computing devices into storage computing services.

Cloud computing in a broad sense, is a remote service, its implementation mechanism is transparent to users---cloud computing is the essence of Internet applications. It's just that most of the previous services were centered on desktop and PC programs, and not as complex as it is now (a lot of rich media and complex implementations and interactions), the user base is not as large as it is today (hundreds of millions of users or support global services), so there is no cloud computing as a special ability to study and use.

The solution for cloud computing is now primarily a platform-side component:

One is infrastructure services (infrastrcture as a service), mainly provide computing centers, hardware resources, system software and other infrastructure services, the current IBM,SUN,HP vendors are providing similar services; In the domestic century Internet 09 long released China's first commercial cloud computing service platform Cloudex, to provide domestic users based on "cloud computing" mode of Internet infrastructure services.

One is the platform service (Platform as a service/software as a service), which mainly provides application development and running platform services, Googleapp Engine (running user-written web applications on Google's infrastructure, And can be easily expanded based on the amount of traffic and the growth of the data storage needs, Amazon launched the EC2 (elastic Computing Cloud) and S3 (simple Storage service) services, Microsoft's cloud computing platform, Azure Services Platform, released at the end of 2008, is in this category

One is business services (Business as a service), mainly providing a variety of business services, Google's search services, Taobao E-commerce platform are typical of this type of service representative.

These cloud computing platforms will make the most direct changes to users of businesses, especially small and medium-sized enterprises, including service developers and service providers: enabling them to distribute and efficiently manage and maintain it infrastructures, as well as enable them to be more affordable and flexible Use or build the various applications that they want.

For example, in April of this year, Visual Studio 2010 was officially released-running in the Azure platform cloud, with Microsoft customers, partners, and developers able to quickly deploy their own development applications on Azure, in a pay-as-you-go manner--anyone, Development can be done anywhere, coding, collaborating, debugging, testing, deploying, and running in the cloud.

For individuals, future applications will be transferred to the Web as the core of various activities, computing (computer), communications (communication), Consumer Electronics (Consumereletronics), content will also complete the fusion, this PC , the lines between mobile phones and home appliances are blurring, and they all degenerate into a simple terminal, without the need to install software or to bother with the configuration and upgrades of these software, which are used only for network connectivity and services that use cloud computing.

The future mobile terminal market is 10 times times the mobile phone, is 100 times times the PC, ignoring the terminal adaptation, can efficiently complete information storage, filtering, processing and display of cloud services (cloud applications), marginal profit is almost unlimited.

At present, Internet television is a very good example.

Of course, whether cloud computing will eventually reach individuals is more difficult than the enterprise.

Personal data is stored in the cloud and processed in the cloud (such as social networks, online offices, mobile commerce, etc.), so how to ensure long-term stable and secure content storage, and privacy of the leak? (Personal services pay more attention to low cost than enterprise services, and the overall layout of services in the public network)

Many individual user content in the cloud storage and processing after the completion, will be launched to share and spread---personal services more entertainment and community, then how to ensure that the content of the copyright security and content health?

Is it for personal service, business model or advertising? After all, it's hard for individuals to pay for it.

The road to cloud computing, which is just beginning. However, the cloud computing model and vision must be the future direction ... All future services will be cloud .... Both businesses and individuals benefit from it ... Lower cost, more choice, better service ...
