In terms of System Architecture and Data Processing Technology, cloud computing technology can be divided into three layers: hardwar
We know that there are two ways to improve the computing capability of a computing system: one is to improve the capabilities of a single computing device and the other is to increase the computing devices. We know that the improvement of computing capability of a single dev

Recently looking at business model-related books, the brain has a cloud computing model, thinking for a long time, still vague, or to share out their own ideas, but also want to listen to different voices and opinions, feel their own talents, may be some of the following technical problems and misunderstandings, are welcome to criticize the people from all walks of life.

Marketing campaigns may need to automatically send e-mail, faxes, letters, or voice messages to a large number of addresses. The parallelism of the grid allows such sending activities to be done in a very short time, regardless of the amount of work.

Preface
Recently, many cloud computing-related content has been collected. On the one hand, it is due to personal interests and hobbies. On the other hand, it has participated in some conferences and seen the future development direction of enterprises,
In addition, in light of the current work needs, I would like to summarize som

Infrastructure services
At the bottom of the cloud is the infrastructure services layer. Here, we see a set of physical assets, such as servers, network devices, and storage disks that are provided to consumers as supply services. The services here support the application infrastructure (regardless of whether the infrastructure is provided through the cloud) and more users. For platform services, virtua

Cloud computing is a service, and cloud computing platform is a service.. Let's take a look at the cloud computing platform categories, such as IaaS,
the development and convergence of traditional computer and network technologies, such as grid computing, distributed computing, parallel computing, utility computing, network storage, virtualization, and load balancing. The ultimate goal of cloud
Into the 2011, not talking about "the cloud" of it meetings was almost gone, manufacturers are scrambling to launch the "cloud" concept and program, the user is gearing up to project construction; we discuss the "cloud services" model of the industrial chain, the imagination of the "cloud economy" of the grand Blueprin

This is what the engineers say about the stack, the IaaS, PaaS, SaaS three tiers we hear. The IaaS layer is like a PC's base hardware plus driver, and the
storage technology, as well as the development of software technology, such as SOA, Web2.0, and Internet technology. At present, cloud computing providers have basically reached a consensus to divide cloud computing technologies into three layers: Infrastructure as a service (IAAS) and platform as a service (

The middleware of the Standard Architecture system shields the differences between different operating systems and provides reliable and stable Service Assurance on Virtualized hardware and operating systems, which is also the core of
