Cloud Technology

Cloud computing (cloud computing), one of the most basic concepts of distributed computing, is to automatically break up huge computing processes into countless more subtle subroutines through the network, And then to the large system composed of multiple servers after the search and calculation and analysis of the processing results back to the user. With this technology, Web service providers can deliver tens of millions or even billions of messages in seconds to achieve the same powerful network services as supercomputers. The simplest cloud computing ...

Perhaps a lot of people are not clear about the various forms of cloud computing, the following article on this detail, the InfoWorld Web site and dozens of companies, analysts and it users to discuss the main forms of cloud computing: 1.SAAS (software as a service) This kind of cloud computing service delivers programs to thousands of users through browsers.

In order to improve the deployment speed of virtual machines in a cloud environment, we first need to consider parallel deployments and collaborative deployments. First look at the parallel deployment, which is to deploy the virtual machines to multiple physical machines at the same time, ideally, parallel deployments can multiply the time required for deployment, but this approach is susceptible to network bandwidth and cloud deployment server read and write capabilities. For example, in the case of limited network bandwidth, the cloud deployment server runs multiple deployment tasks at the same time, these tasks compete for network bandwidth, and when network bandwidth is full, deployment speed can no longer be further improved ...

What new content can we expect from the next generation of cloud computing platforms? What other features or performance are available to the next generation platform, or are some of the earlier competitors already offering? The best part of the cloud computing platform we have now is to eliminate the need for businesses that want to own and run their own hardware. Unfortunately, you still need some hardware knowledge to properly manage your services. Now the provider asks you to add a "server" or "instance" with specific hardware specifications. They are different in the specs you can set ...

R: It's not a real language. Part of the reason we learn about R is that it's not really a programming language. John Cook, an R expert, said: "R is a statistical interactive environment, not a real programming language." It is more helpful to think of R as an interactive environment containing programming languages. "But as Bob Muenchen emphasizes, R is even harder for people who are proficient in SAS and SPSS data tools." About R for analyst ...

As a member of the cloud services family, the growth of platform-service (PaaS) is particularly slow. While PAAs has a great advantage, it is also the most difficult to deploy PAAs with respect to other types of cloud services. However, experts believe that PAAs may soon change the current state of backwardness. Gartner, a market research institute, estimates that global PAAs revenues are around $1.2 billion trillion in 2012. Despite a larger increase compared to the 900 million dollars in 2011, but with hosting services in 2 ...

In a statement last week, Salesforce.com said that the number of participants in the Dreamforce meeting was about 120,000, which is really impressive in terms of numbers alone, but it is hard to argue that this year's meeting is larger than last year's. This is a good way to say that SaaS is still alive and driving the development of cloud computing, but on the other hand, SaaS has not received much attention in all the discussions about cloud computing. On the contrary, many of us in the thick clouds are talking about the only bright light of the new things, ...

With the rapid development of the Internet, various traditional industries have begun to use the power of the Internet to expand their traditional business, from the involvement of E-commerce to software and the Internet integration, the traditional software industry is facing from the Internet business model to change.
