Cloud computing is a concept, not a specific technology. Virtualization is a specific technology, which refers to the virtualization of hardware resources to achieve isolation, scalability, security, and resources can be fully utilized. But things that seem unrelated, there are still inextricable relationships behind them. The development of cloud computing has made virtualization technology more and more familiar. So what is the relationship between cloud computing and virtualization? Let us look at it below: Speaking of virtualization, it generally refers to the physical entity, through the software model, to form a number of virtual existing systems, in fact, whether it is operational or physical, but divided into several regions or time domain division. The foundation of cloud computing is virtualization, but virtualization is only part of cloud computing. Cloud computing is an application after virtualizing several resource pools. Based on the above theory, many people believe that virtualization is just the foundation of cloud computing. It is the wedding dress for the rapid development of cloud computing. In the end, it is just cheaper for cloud computing, which promotes the development of cloud computing. Virtualization is just cloud. Calculate a small boosting force behind. In fact, otherwise, virtualization does not only have these functions. Virtualization is widely used in the IT field. Different virtualization technologies are used for different resources. Now we can roughly divide virtualization into four categories: memory virtualization. Network virtualization, server virtualization, storage virtualization. Memory virtualization: refers to the use of virtualization technology to achieve memory management of computer memory systems. From the perspective of the upper application, the memory virtualization system makes it have continuous and available memory, that is, a continuous and complete address space. From the perspective of the physical layer, it is usually divided into multiple pieces of physical memory. The role of memory virtualization is more to meet the allocation of memory and exchange the necessary data. Storage virtualization: Storage virtualization is now mentioned a lot, the main idea is to separate the storage resources from logical views and physical storage, thus providing seamless resource management for the system. Due to the low degree of storage standardization, storage compatibility is a problem that must be considered. If storage virtualization technology is derived from different vendors, subsequent upgrades and updates will increase the difficulty. Network Virtualization: Network virtualization is a way to use software to separate network power from physical network elements. Network virtualization has much in common with other forms of virtualization. Network virtualization also faces technical challenges. Unlike network devices and servers, he generally needs to perform high I/O tasks, often for proprietary hardware modules for data processing. Server virtualization: Server virtualization is much more widely used in the industry, and it is also recognized by people. With server virtualization, we can centrally manage the CPU, memory, disk and other hardware of the server through centralized dynamic on-demand distribution. The utilization of resources can be provided. In fact, the principle of cloud computing is more to use computing virtualization. Of course, the other three may also be used in some cloud computing, but virtualization does not only serve cloud computing. Still worthy of our attention. KNB1-32 Miniature Circuit Breaker
KNB1-32 Mini Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automatic protection of low-voltage electrical distribution. Its role is equivalent to the combination of switch. Fuse. Thermal Relay and other electrical components. It mainly used for short circuit and overload protection. Generally, According to the poles, mini Circuit breaker can be divided into 1P , 1P+N , 2P, 3P and 4P.
