This article introduces the characteristics of JSP CVM and what matters needing attention for CVM registration. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

JSP CVM refers to JAVA Chinese standing on the basis of large-scale distributed computing systems, through virtualization technology to integrate IT resources for various industries on the network to provide Internet infrastructure services. CVM has advanced features such as self-management and data security, such as automatic failure recovery and prevention of network attacks, which can not be achieved by other hosts, which helps you greatly reduce your cost.

The first major feature: virtualization technology

The virtualization platform virtualizes more than 1000 server clusters into multiple performance-configurable virtual machines (VM), monitors and manages all VM in the whole server cluster system, and flexibly allocates and schedules service resource pools according to the actual situation of resource use.

The second major feature: distributed storage

Distributed storage is used to integrate a large number of servers into a supercomputer and provide massive data storage and data processing services. Distributed file systems and distributed databases allow access to common storage resources, and IO sharing of application data files can be achieved.

The third major feature: resource scheduling

Virtual machines can break through the limitations of a single physical machine, and dynamic resource adjustment and allocation can effectively clear the single point of failure of servers and storage devices so as to achieve the highest level of availability. If the host of the computing node needs us to maintain, we can migrate the virtual machines running on the host of the computer node to other idle nodes without downtime through the hot migration technology, and the users will have no feeling. If the computing node is physically damaged, we can also migrate its business to other nodes to run in about 3 minutes, which greatly improves the reliability of the system.

The fourth feature: intelligent management platform

The CVM resources are provisioned through the API interface, so that the VM system installation, backup, remote restart, status monitoring and other functions can be completed with one click.

JSP CVMs are mainly object-oriented enterprise users with high requirements for system stability and data security.

1. Enjoy the entire CVM without any interference and support remote desktops

two。 Distributed cluster storage, 4 mirror backups, one-click recovery of all data to ensure that the data is foolproof

3. Support for Tomcat 6.0, 7.0 and Resin 3.0.

4. JDK version: JDK 1.6 / JDK 1.7 optional

5. Database support: MySQL 5.0, MSSQL2000 5.5

6. Fully support JSP, Servlet, SSH and other frameworks

7. The technical support is provided by the technical experts of JAVA Chinese station.

8. Complete the website record for the customer free of charge

Notes for JSP CVM:

1. Website record description

According to the relevant regulations of the state, all websites established in mainland China must first be put on record with the relevant departments, otherwise they will not be allowed to start a website, so if you do not put on record in time, the website may be shut down or even fined.

2. Matters needing attention in website content

All CVM customers shall strictly abide by the relevant network policies and regulations such as the interim provisions of the people's Republic of China on the Administration of International networking of computer Information Networks and the provisions on the Administration of Internet Electronic announcement Service issued by the State Council. The following websites are absolutely prohibited on the server of this site:

(1) discussion website on political issues

(2) sexual products, sexual content, pornographic websites

(3) gambling and gambling websites (including football, lottery, etc.)

(4) it is forbidden to use our server to send spam and mailing lists.

(5) BBS/ forums / blogs and other procedures can be placed after written examination and approval, and the written examination and approval should be contacted with the local information and communications management department. If the above situation is discovered, the relevant departments have the right to close the relevant website without notifying the user, and do not give a refund, and please report to the public security organ for relevant processing.

3. Pay attention to the release and operation of the website program

(1) all JSP/JAVA programs should be tested and run in the local environment before uploading, so that the release of the website can be completed more quickly.

(2) because the JSP CVM has many classes and packages to upload, if these classes and packages make a mistake in the upload process, the website cannot be loaded by the JAVA application server, and such problems are time-consuming and laborious to find. If there are more classes and packages of the website or the FTP upload speed is not very ideal, the editor suggests to contact the technical staff to package and upload and unpack and release.

So much for sharing about the characteristics of CVM and what matters needing attention for JSP CVM registration. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
