This article mainly explains "what the CVM refers to". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what the CVM refers to".

1. What is the CVM?

Cloud host is one of the important components of cloud computing applications, and the underlying products located in the cloud computing pyramid mainly come from the platform of self-cloud computing. This platform contains three core elements of Internet application: computing, storage, network, and providing users with a service of Internet public facilities.

CVM represents a new generation of host leasing services, which comprehensively includes high-performance servers and high-quality network bandwidth, which can be said to fundamentally solve the shortcomings of traditional host rental prices and uneven service quality. thus, it can fully meet the needs of small and medium-sized enterprises, individual webmasters and other small users for host rental services with low cost and easy management. Cloud hosts have been widely popular in Hong Kong, the United States and other economically developed areas, and the mainland has just sprung up, which is a new server development direction that can completely replace existing servers.

2. How to purchase a CVM

The first key point is the price of the CVM.

Service providers with very low performance-to-price ratio should be able to rule out directly. The quotations in the CVM market are mixed and uneven, but there will still be a more mainstream price. If the quotation is higher than the mainstream price range, you can pass it directly. Take a CVM with dual-core, 4-gigabyte memory, 200-gigabyte hard disk and 10-megabyte bandwidth as an example: the quotation of a CVM provider is much higher than that of other mainstream host service providers, and many people will question it. Does such a wide difference in price mean that there is also a great difference in product performance? The editor will say no. So what is the reason why there is such a big gap between the two prices? The editor believes that the main reason is that each company's marketing strategy is different. Cloud host is a new product, and its price does not form an established price in the psychology of users, so it is only natural that there will be a psychological space for service providers to bid all over the sky. In the minds of some cloud service providers, they will think that the higher the price, the easier it will be for buyers to think that their products are better than others. Under such circumstances, when purchasing CVMs, we must be careful not to be blinded by those high-priced and low-energy CVMs.

The second key point is configuration.

At first, you don't have to buy a CVM with too good performance. Users can choose a CVM with a relatively low configuration. When you find that it is not enough, you can ask the CVM service provider to upgrade the service. The upgrade only takes one day. Usually, it can be done the next day.

The third key point is the choice of CVM room.

Generally speaking, users are advised to choose computer rooms in Beijing or Shanghai, because these two places have the most developed networks and low incidence of network latency, and most websites across the country also use IDC computer rooms in Beijing and Shanghai.
