In modern society, cloud computing has become one of the indispensable high-end technologies. Whether it is a business or the Internet, its role is quite large. Virtualization is the most important supporting technology for cloud computing. What is the relationship between them?
Virtualization is an important supporting technology for cloud computing. Cloud computing is an add-on, use, and delivery model of Internet-based related services that typically involves providing dynamically scalable and often virtualized resources over the Internet. Through virtualization, applications and data can be presented to customers in different ways at different levels, facilitating users and developers of cloud computing. The virtualization process of cloud computing provides organizations with the flexibility to improve IT operations and reduce costs.
Cloud computing is done by distributing computing across a large number of distributed computers, rather than local computers or remote servers, and the enterprise data center will behave more like the Internet. This allows companies to switch resources to the applications they need and access computers and storage systems as needed. For cloud computing, virtualization is essential.
Cloud computing treats computing as a public resource rather than a specific product or technology. As early as the 1970s, large computers had been running multiple operating system instances at the same time, and each instance was independent of each other. But until today, advances in hardware and software have made virtualization technology likely to appear on popular x86 servers based on industry standards.
In the cloud computing environment, software technology and architecture will change significantly. First of all, the developed software must be compatible with the cloud, can be integrated with the cloud platform with virtualization as the core, adapt to the dynamic changes of computing power and storage capacity; second, it must be able to meet the needs of a large number of users, including data storage structure and processing. The third is to be Internet-based, based on the Internet to provide software applications; Fourth, higher security requirements, can resist attacks, and can protect private information; Fifth, can work in mobile terminals, mobile phones, network computers and other environments.
In addition, in the cloud computing environment, due to changes in software development work, it will also affect and change software testing. Cloud computing delivers various IT resources to users over the Internet in a serviced manner. However, virtualization itself does not provide users with a self-service layer.
Some experts believe that the cloud computing model allows the terminal to supply its own servers and applications, even virtualized resources. For enterprises, a large amount of computing resource consumption also makes system administrators tend to provide virtual machines.
In general, virtualization and cloud computing are not bundled technologies, but can complement each other to provide better services to users. In cloud computing deployments, virtualization technology can make IT resource applications more flexible. In the application process of virtualization, cloud computing also provides resources and services on demand. In some specific scenarios, cloud computing and virtualization cannot be stripped. Only by matching each other can we better address customer needs.
AC (Alternating Current) Power cord is to transmit high voltage. It is used to drive machinery or home appliances. Since AC Power Cord is output of high voltage electric power, there is a risk of electric shock injury, therefore, All the AC power cord must comply with safety standard to produce. DC (direct Current) power cord is used to the applicance with lower voltage mostly, so safety requirement is less stringent.
