In layman's terms, the virtual host is a (or a group) of server resources (system resources, network bandwidth, storage space, etc.) according to a certain proportion of the partition into a number of relatively independent "small host." Each such "small host" in the function can realize www, FTP, mail and other basic Internet services, like using a stand-alone host. Although the current charge of the virtual host full street are, cheap also seems a lot, but sometimes in need or other options, free virtual host has been a lot of people to do the first choice of station. So what should we pay attention to when choosing a free virtual host:

The stability of space

Stability is the choice of free space the most attention, if a site's space instability, will lead to search engine spiders can not crawl site content, so search engines will not be able to index your Web page. This will lead to a direct result of the site is the search engine down the right, or even k off. So in the choice of free space, we must choose a stable. I have been using the portal through the 2G almighty free space, portal access to the space using the portal will be used by the server cluster technology framework, to my use of the effect and experience, stability in this regard portal pass is still guaranteed.

Second, the size and function of space

Now there is not a lot of service providers in the Super stable space of G, and those who claim that the unlimited size of free space is simply a talk. And a lot of free space there are more than n restrictions, there are many do not support MySQL or SQL Server database, but also do not let the Forum program and so on, which almost indirectly rejected us to use the current mainstream programs, such as the need for database support of the CMS and DW and other forums. After comparison, I still recommend that you use portal free space, portal space Initial size of 2G, in the future can also be applied to increase the demand for more space, this seems very humane. And the portal provides a universal space, then PHP, ASP, asp.net, CGI and MySQL or SQL Server, Access database, etc. is certainly supported, as I use this period of time, this is also good to say.

Third, the space flow problem

Now a lot of charge space will have traffic restrictions, of course, free space is no exception. If the site's traffic exceeds the limit, it can cause the site page to not be displayed. This is also a great impact on the development of the site, so we recommend that you choose free space when it is best to choose those who give us large or unlimited flow of space.

Iv. Space Providers

Choose free space When we should also choose a good reputation service provider, which will provide you with a stable operation of the stability of the protection of the site. If you choose to provide free space for the individual or a small company to provide space, then once the space is out of the question, the solution is very troublesome, the feedback problem is basically there is no return. I had to choose the use of the portal space, in fact, a big reason is because the portal is a tiger wing Nets 51.net, and the Tiger Wing network to believe that the webmaster are aware that many people began to learn to do the site is estimated from the Tiger Wing network began. And the use of portal space this period of time, I feel the most is their customer service and technology are very enthusiastic, a lot of problems will be timely to help me solve, regardless of the size of the problem, will give me a satisfactory answer. Since the beginning of contact with the portal space when a bit of food, so there are many problems, including the site's record, the binding of the domain name, the opening of the Post Office, space use problems and so on and so on are in the technical enthusiasm and timely help to complete. Contact with the Internet in recent years, I have used a lot of free space, but now I have made up my mind to use the space of the portal.

V. Space Environment and SAFETY

Remember the space that a space provider has used before, hard to do a big six months of station, suddenly the site was turned off, and then finally contacted the customer service, they told me a bunch of because the server costs too high, too much pressure and so on nonsense excuses, I said that since the closed then put my site data back to me, But they are also a bunch of excuses, the word is to say what the user too much, too much data, not for your personal recovery and so on, and then strongly recommend me to use their charging host services, said as long as the money, they help me to the data to the charging host. If we encounter such a space business, is also very unlucky thing, so we choose free Host must choose those who have the strength of the service provider, otherwise be fooled to find regret medicine is not. In addition, the reason for the choice of the strength of the service providers to provide space, but also for security considerations, if due to space insecurity, site Zooey has been a lot of horse or data loss, but also very deadly. And I choose to access the free space portal, but also based on this consideration, the portal through all the servers under the protection of the firewall, ASP. NET Server is also equipped with anti-virus, Trojan horse program, can effectively prevent the Web page is black, hanging horses and so on. In addition, all the service space of the portal is directly connected to telecom through the exclusive bandwidth of more than 100M, Netcom backbone of the network, the greatest degree of assurance of North-South interoperability, things, and all Web servers using reverse proxy acceleration technology, so that different categories of Web pages can be sent to the fastest speed to the client, Greatly enhance the access speed. More importantly, the portal provides customer service 24-hour telephone, instant online, e-mail and other means of all-round technical support, there are problems can be the most timely and effective help and resolution is the most needed for users.

Noun Explanation: What is the virtual host technology

The so-called virtual host, is to run a server running on the Internet into multiple "virtual" servers, each virtual host has a separate domain name and complete Internet server functions. The different virtual hosts on a server are independent, and are managed by the user, in the view of the outside world, each virtual host and a separate host are exactly the same. However, a server host can only support a certain number of virtual hosts, when more than this number, users will feel a sharp decline in performance.

What is server cluster technology:

A server cluster is a set of independent servers that are managed as a single system for higher availability, manageability, and greater scalability. Server clusters have three key advantages: higher availability, easier manageability, and more cost-effective scalability. Availability: MSCS can automatically detect application or server failures and can quickly reboot on surviving servers, and users will only experience instantaneous service pauses. Manageability: MSCS enables administrators to quickly check the status of all cluster resources and easily assign workloads to different servers in the cluster. This is useful for manual load balancing and "rolling Upgrades" the server without having to take important data and applications offline. Scalability: Cluster-enabled applications can use MSCS services through the MSCS Application Interface (API), enabling dynamic load balancing and scaling across multiple servers in a cluster.
