This article mainly explains "what are the characteristics of the java CVM". The content of the explanation 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 are the characteristics of the java CVM".

Different virtual hosts on a server are independent and managed by users. However, a server host can only support a certain number of virtual hosts, and when it exceeds this number, the performance will relatively decline. Java CVM is a kind of virtual host, which is a form of service used to establish web website, which supports commonly used java technology. Java CVM is an environment for running java programs.

The emergence of virtual hosting technology is a great contribution to Internet technology. Multiple virtual hosts share the resources of a real host, and the hardware costs, network maintenance costs and communication line costs borne by users can be greatly reduced. Become an affordable network for everyone! At present, many small companies in the United States have set up their own servers on the network, many of which are cloud virtual machines.

The characteristics of java CVM virtual machines are:

1. It has a unique tomcat service: each site has a unique tomcat, which improves the security of the site and avoids individual resource-consuming sites, thus affecting the operation of other sites. J2 host supports tomcat5.0 and 6.0free switching.

2. Independent IP address: each site has an independent IP address, which can reduce network attacks and increase friendliness to search engines.

3. Restart the tomcat service independently: each site has an exclusive tomcat. You can log in to the host control panel to restart your tomcat service to facilitate the deployment of complex applications.

4. Support tomcat full log download: users can download their own tomcat running log files through ftp to facilitate users to debug the program.

5. Support more Java applications and provide rich test cases.

Virtual host CPU occupancy: CPU refers to the proportion of your virtual host to the CPU resources of the entire server during operation. Now many virtual host vendors boast that there is generally no limit on the number of IIS to attract customers. In fact, the reality is that IIS can make no restrictions on your CPU occupancy, so that although your IIS is not restricted, because CPU occupancy rarely reduces the availability of your virtual host. In fact, it is a word game played by virtual host vendors.

These are the characteristics of java CVM virtual machines. It divides a server running on the Internet into multiple "virtual" servers, each with an independent domain name and a complete Internet server function. It is independent and flexible in data security.

Thank you for your reading. the above is the content of "what are the characteristics of java CVM virtual machines". After the study of this article, I believe you have a deeper understanding of what the characteristics of java CVM virtual machines are, and the specific usage needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
