Cloud Computing Basics Quiz

1. Cloud computing is all the data are stored on the server, we need to come directly to use, the data is not placed in the local, virtualization technology is to put data on the server, and the local computer does not have data, then cloud computing and virtualization technology is what difference?

A: Cloud computing is a computing idea, and implementing a specific cloud computing infrastructure requires a combination of technologies, and one of the most important technologies is virtualization.

2. What about IBM's Blue Cloud program?

A: IBM's cloud computing is a combination of software and hardware, allowing enterprise users to experiment with cloud computing models, the cloud computing model allows computing to run on a network-like environment by architecting a distributed, globally accessible resource structure, which is not limited to local machines or remote server farms. The magic of IBM Cloud is that customers who end up using this resource don't need to worry about where the resource is and how to deploy what he wants. He just submits the application, then a series of automated processes, and he finally gets the turnkey solution (turnkey solution). Namely: The customer tells cloud his demand, finally cloud satisfies customer's demand, but the customer does not have to manage resource disposition and process detail. Customer requirements, such as how much computing power is required, what software needs to be deployed, and what tests are required. The rest of the business is out of the control of the client. The cloud's work is done by giving the customer an IP address that the customer can use to address the IT environment that meets his needs. All the things cloud has been done. This is the most attractive part of the cloud: the customer only needs to ask, the rest of the thing is an automated process ("process") to complete.

3. IBM, Google, Yahoo all have cloud computing, these cloud computing what is the difference?

A: IBM's cloud computing technology is primarily used to address the management of next-generation enterprise data centers. He mainly provides the cloud computing management platform for the enterprise and provides the related service, helps the enterprise to build its cloud computing infrastructure. Google's cloud computing is to make its own infrastructure into a cloud computing platform, and based on this platform for all Internet users to provide cloud computing services, the current provision of services mainly app. Yahoo's cloud computing is similar to Google's.

4. What is the current state of cloud computing in the industry, whether it will also be to standardize the direction of development?

A: At present, major it Manufacturers (IBM, Microsoft, Google, Amazon) have launched their own cloud computing products, but the function of each product and coverage of the field is very different, there is no unified standard. With the gradual maturation of each product, there will be more perfect standards so that each manufacturer's "cloud" can be interconnected and interoperable.

5. "Cloud computing" the realization of this concept ultimately depends on the software to achieve and manage, or rely on the future of the hardware to set up a reasonable arrangement can be achieved?

A: At present, software is needed to realize the virtualization management and scheduling of hardware resources.

6. "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. I don't quite understand the explanation. Cloud computing is the development of these technologies, so how does it differ from these technologies? is cloud computing a combination of these technologies?

A: Cloud computing is not a specific technology, but a computational idea or computational model. It can be achieved through these technologies.

7. Cloud computing is the solution to the problem of IT services, how can it be combined with SOA?

A: SOA solves the problem of integration of services. Cloud computing can serve as a provider of stand-alone services that can be integrated through SOA. Cloud computing can be used to guarantee the quality of service and non-functional requirements for services in an SOA.

8. How is cloud computing developing in the US and Europe? Hasn't started in China yet?

A: In the corporate marketplace, IBM has helped multiple customers, including Chinese customers, successfully implement their own cloud computing infrastructure.

9. The views of cloud computing vary among major manufacturers: Google believes that cloud computing will severely weaken terminal performance and that Microsoft's business model will face severe challenges. Intel believes that many of the application patterns in the cloud computing era will migrate to digital management, but do not believe that cloud computing will lead to a weakening of the performance of the terminal, instead, as Internet applications continue to expand (for example, from text browsing, retrieval to video applications and video retrieval), the terminal performance is increasing, The importance of terminals, instead of weakening, will be more pronounced. Microsoft's view puts forward the concept of "cloud-end computing", that is, "cloud" and the terminal will have a strong computational power. So what is IBM cloud computing? What is the relationship between cloud and end?

A: IBM's cloud computing is primarily enterprise-oriented. IBM's envisioned next-generation enterprise data Center will centralize all business data and computing power. As a result, clients of future enterprises tend to use thin client mode.

10. What impact does cloud computing have on high-performance computing and supercomputers?

A: Some technologies in cloud computing (such as the Hadoop programming model, virtualization technology) can be used to improve the system architecture and computational methods of High-performance computing. Some high-performance computing tasks can be done by the cloud infrastructure.
