Cloud services, cloud terminals, cloud computing differences

What is cloud service?


　　


I would like to give you a simple description: It is smart enough to be able to according to your location, time, preferences and other information, real-time to your needs to make the expected. In this new mode, the search for information will be done for you, not for you. No matter what device you use, no matter what type of service you need, you will have a consistent and consistent ultimate experience.


　　


by breeding a large number of start-up companies to provide a wealth of personalized products to meet the market's growing personalized demand. Its breeding mode is for the start-up companies to provide funds, promotion, payment, logistics, customer service set of services, the operation of their own capacity like water and electricity to the external use as needed. This is the business model of cloud services.


　　


Cloud Service's birth premise is: the Internet breaks the geographical division to form a unified big market, provides the product for the personalized demand to begin the profit. Its objective effect is: To minimize the cost of starting a business, entrepreneurs focus on creativity and other core links, operations and management will no longer be important. Small companies are starting to challenge big companies to subvert the "scale winning" industrial civilisation. Our society and culture will be more independent and free.


　　


Cloud Terminal


　　


Next-generation PCs, called "Cloud terminals", no longer require central processing units, hard drives, graphics cards, and even operating systems and applications, because all of this is done by a common cloud server, a small set-top box, or directly built into a monitor. "The price is only 500 yuan." ”


　　


Cloud Terminal is by far the most economical computer network solution, single Taiwan price only hundreds of yuan, according to statistics, to achieve the same function of the commercial network system, cloud Terminal system and traditional PC system: in the procurement link will save 70% of the input; In the system Operation dimension, will reduce the cost burden of 90% , in the use cost, 50 cloud terminals are equivalent to a common PC computer power consumption, electricity savings is considerable.


　　


"Cloud computing" will change the current computer "chassis + Monitor" mode, in the future, including television, mobile phones, game consoles can become the network's end equipment, the computer because of the ubiquitous, so that we can not see it, this is the ubiquitous computing. And as the concept of cloud computing matures, telecom operators, hardware suppliers and software service providers merged into one, the traditional PC industry, the operating system and the processor platform in the dominant position will be reduced, PC manufacturers will have more power of speech and development opportunities.


　　


Cloud Computing (Cloud computing) is a new way of sharing infrastructure that can connect huge system pools together to provide a wide range of IT services. Many factors contribute to the need for such environments, including the rapid growth of Web2.0 applications such as connectivity devices, real-time data streams, adoption of SOA, and search, open collaboration, social networking, and mobile commerce. In addition, the improvement of the performance of digital components has greatly increased the size of the IT environment, thus further strengthening the need for a unified cloud management.


　　


Cloud Computing-defining cloud computing as a narrow definition of cloud computing is the delivery and usage pattern of IT infrastructure, which means acquiring the required resources (hardware, platform, software) on demand and in a scalable way over the network. A network that provides resources is called a "cloud." The resources in the cloud can be extended indefinitely by the user, and can be obtained at any time, on demand, at any time, and paid for by use. This feature is often called the use of IT infrastructure like hydroelectric power.


　　


Generalized cloud computing refers to the delivery and usage patterns of services, which means that the required services are obtained on an as-needed and extensible basis through the network. This service can be it and software, Internet-related, and can make any other service.


　　


cloud computing is often confused with parallel computing (parallelcomputing), distributed Computing (distributedcomputing), and Grid computing (gridcomputing). Cloud computing is the result of a mixture of concepts such as virtualization (virtualization), Utility Computing (utilitycomputing), IaaS (infrastructure as a service), PaaS (Platform-Service), SaaS (software as a service), and so on.


　　


Cloud Computing-Features


　　


(1) Super scale. "Cloud" has a considerable scale, Google Cloud computing already has more than 1 million servers, Amazon, IBM, Microsoft, Yahoo, etc. "cloud" has hundreds of thousands of servers. Corporate private cloud typically has hundreds of thousands of servers. The cloud gives users unprecedented computing power.


　　


(2) virtualization. Cloud computing enables users to obtain application services in any location using a variety of terminals. The requested resource is from the cloud rather than the fixed physical entity. Applications run somewhere in the cloud, but in fact the user does not need to know or worry about where the application is running. Only need a laptop or a mobile phone, you can through the network services to achieve everything we need, even such as supercomputing tasks.


　　


(3) high reliability. The cloud uses such measures as data duplication fault tolerance and computing node isomorphism to ensure high reliability of services, and using cloud computing is more reliable than using a local computer.


　　


(4) versatility. Cloud computing is not specific to the application, in the "cloud" under the support of the structure of the ever-changing applications, the same "cloud" can support the operation of different applications.


　　


(5) High scalability. The scale of the cloud can be scaled dynamically to meet the needs of application and user-scale growth.


　　


(6) on-demand service. "Cloud" is a huge pool of resources that you buy on demand; The cloud can be billed like running water, electricity and gas.


　　


(7) is extremely inexpensive. Because the "cloud" of special fault Tolerant measures can use extremely inexpensive nodes to form the cloud, "Cloud's automated centralized management enables a large number of enterprises to not burden the increasingly high cost of data center management, the" cloud "of the universality of the resource utilization than the traditional system significantly increased, so users can fully enjoy the" cloud "low-cost advantage, It often takes hundreds of of dollars and a few days to complete a task that previously required tens of thousands of dollars and months to complete.


　　


Cloud Computing-Fundamentals


　　


Cloud computing (Cloud Computing) is the development of distributed processing (distributed Computing), parallel processing (Parallel Computing) and Grid computing (grid Computing), or the business implementation of these computer science concepts.


　　

The basic principle of
cloud computing is that enterprise data centers run more like the Internet by distributing computations across a large number of distributed computers, rather than on local computers or remote servers. This allows the enterprise to switch resources to the required applications and to access the computer and storage systems as needed. This is a revolutionary move, for example, from an ancient single generator to a power plant's centralized power supply model. It means that computing power can also be used as a commodity circulation, like gas, water and electricity, easy to use, low-cost. The biggest difference is that it is transmitted over the Internet. The blueprint for cloud computing has come to pass: in the future, with just a laptop or a mobile phone, you can do everything we need through Web services, even tasks such as supercomputing. From this perspective, end users are the real owners of cloud computing. The application of cloud computing consists of the idea of combining forces with each of these members. In the most fundamental sense, cloud computing is the ability to use software and data on the Internet. For cloud computing, Kai-fu Lee (Google global vice president, China regional president) played an image of the analogy: the banks. The first people just put the money under the pillow, and then have a bank, very safe, but it is more troublesome to cash. Now it is up to the banks to get money from any one of the outlets, even through ATMs or foreign channels. It's like using electricity without having to be equipped with a generator and buying it directly from a power company. "Cloud" brings is such a change-by the Google, IBM, such as professional network companies to build computer storage, computing centers, users through a network of browsers can be very convenient access to the "cloud" as data storage and application services center. Cloud computing has now developed two broad areas of cloud security and cloud storage. such as domestic rising and trend technology has begun to provide cloud security products, and Microsoft, Google and other international heads are more involved in the cloud storage area.


　　


Cloud Computing-development conditions


　　


cloud computing is bound to become increasingly common, gradually developing into mainstream computing models instead of centralized mainframe computers:


　　


1. The first reason for the distributed system now is that he has a better performance-price ratio than a centralized system. You don't have to pay hundreds of thousands of dollars for efficient computing.


　　


2, most applications are distributed in themselves. such as industrial enterprise application, management department and the scene is not in the same place.


　　


3, high reliability. Redundancy is not only a necessary condition for biological evolution, but also information technology. Modern distributed system has highly fault-tolerant mechanism, and the control reactor mainly uses distributed to achieve high reliability.


　　


4, scalability. Buying a higher-performance mainframe, or buying a mainframe with the same performance, is much more expensive than adding several PCs.


　　


5, highly flexible. Can be compatible with different hardware manufacturers, compatible with low configuration machines and peripherals to obtain high-performance computing.

Cloud Computing is a buzzword that encompasses development, load balancing, business models, and architecture, the future model of the software industry (Software10.0), or simply, cloud computing is the Internet-centric software.


　　


Reuven Cohen


　　


Cloud Computing is a web-based service designed to allow users to pay only for the features they need, while eliminating traditional software investments in hardware, software, and expertise. Cloud computing allows users to get their applications out of the complexity of technology and deployment.


　　


Douglas Gourlay


　　


cloud computing refers to a big ambition, basically, is to allow users to access technical services through the Internet, and now every time you log on to Facebook or search for a flight, you are actually using cloud computing.


　　


Praising Gaw


　　


Cloud Computing is the new Web2.0, a technology-rich market bloom. Cloud computing is a new buzzword, just as people used to put a little Ajax on their websites and claim to be Web2.0.


　　

The positive side of the
is that Web2.0 eventually captures the mainstream eyeball, and similarly, the cloud computing concept will eventually change people's minds, eventually erupting into a variety of concepts, hosting services, ASP, Grid computing, software as a service, platform as a service, anything as a service.

from a consumer's perspective, SaaS is a kind of cloud computing, but people in the industry must understand what this means. Simply put, cloud computing is the sublimation of SaaS.

The original intention of the
cloud model is to let the hardware layer consume like on demand, as needed storage space, and in order to bring more power to the cloud model, we need to implement the configuration, deployment and service in a virtual environment throughout the application architecture.

cloud computing is about accessing resources and services that require dynamic change. The resources for application and service requests come from the cloud, not the fixed physical entity. The cloud is a virtual resource that can be maintained and managed by itself.


　　


Cloud Computing-foreground


　　


cloud computing is seen as the next revolution in technology, which will bring about fundamental changes in the way it works and the business model.


　　


First, for small businesses and entrepreneurs, cloud computing means huge business opportunities, and they can compete with big businesses on a higher level with cloud computing. Since Microsoft launched Office software in 1989, the way we've worked has changed dramatically, and cloud computing has brought in cloud offices--more computing power without the need to buy software and save local installations and maintenance.


　　


second, in a sense, cloud computing means the death of hardware. At the very least, those small and medium-sized enterprises, which are growing in demand, are no longer trying to buy expensive hardware, but renting computing power from cloud computing providers. While avoiding hardware investment, the company's technical departments do not have to worry about the hectic maintenance of technology and save time to do more business innovation.


　　


Amazon, for example, its cloud computing products are cheap (and of course lucrative), attracting a large number of small and medium-sized enterprises, even the "New York Times", Red Hat, Sheng disc and other large companies. Amazon offers 15 cents per 1G of storage, and the server rents 10 cents per hour. Each computer in its "cloud" is said to have invested only $300 trillion, assuming electricity consumption is also 300 dollars, and by that rate it would have earned 876 dollars a year without interruption, with a profit margin of about 45% per cent-higher than the gross margin of its sales books.


　　


with the rise of cloud computing, traditional hardware makers are again facing a crisis. Dell, Hewlett-Packard, Sun, and so on for years have been worried about the U.S. market recession, perhaps the hardware market recession is really coming.


　　


Cloud Computing's impact on business models is reflected in the innovation of market space. Harvard Business School Professor Christensen argues that the demand for Gmail has suddenly soared, and that Google's cloud computing system will automatically increase the capacity and number of processors for Gmail without human intervention, and that the increase and adjustment will not increase costs. Relying on cloud computing, Google can add new services at almost negligible cost. If the new service fails, it doesn't matter, turn it off and forget about it. If successful, the system will automatically increase space and processing power for it.


　　


Google CEO Elic Schmidt that cloud computing means returning to the mainframe era from the PC era. "In the PC era, PCs offer a lot of good features and apps, and now they're back in the big time," he said. Now the mainframe can't be seen or touched, but it really is there, in the clouds, in the sky. ”





Cloud Computing-development space


　　


imagination, when the computer's computing power is not limited by local hardware, smaller size, more weight, but can be more robust processing of mobile terminals within reach. We can still run the most demanding online games on a thin, lightweight notebook, and can also edit and process just the photos on the phone by visiting Photoshop online.


　　


more attractive is that enterprises can be very low cost input to obtain very high computing power, no longer invest in expensive hardware equipment, the burden of frequent maintenance and upgrades. For example, the US real estate web site, goosipy, wants to create a database that calculates the number of 670,000 households who buy their own selling property in 12 years to provide better advice to consumers. If they do it themselves, initial estimates will take 6 months and millions of dollars. And in the end, they rented Amazon's "Resilient Computing Cloud" service, and by using Amazon's powerful analytics capabilities, the project was completed in just 3 weeks, costing less than $50,000 trillion--one of the beauty of cloud computing, which is that computing on demand can give full play to the performance of large computer groups. If you only need to use 5% of the resources, you only have to pay 5% of the price, instead of the same as before, for 100% of the equipment to pay.
