Looking for a site in the sky: Virtual Host purchase Guide

Today, the most popular on the Internet is to show personal charm, personal blogs, private BBS, mood pictures ...... Creating a website can make your online image more complete and facilitate unified production and management. But do we store our websites in free space or in free space? In addition, the service provider provides a wide variety of billable spaces. How should we choose? In fact, there are many things to be aware.
Knowledge
Common forms of website Space
First, we need to know several common methods of website space so that we can be targeted.
1. self-built hosts: The self-built hosts mentioned here are not the methods we usually mention to use personal hosts and dynamic IP addresses to set up websites, but to purchase professional servers, in addition, they also need to rent expensive leased lines to local Internet access providers to establish independent host servers. In addition, they also need to provide dedicated management and maintenance personnel for the servers. Because of the high cost, this method is suitable for some large and medium-sized enterprises and specialized ISPs.
2. server hosting: different from self-built hosts, a server is entrusted to a dedicated Internet service provider for Internet access and server hardware management and maintenance, you only need to pay a certain amount of server hosting fee to the access provider on an annual basis. This method is expensive and suitable for small and medium-sized enterprises and ISPs.
3. server Leasing: users do not need to purchase their own hosts. They can submit server software and hardware configuration requirements to Internet service providers according to their business needs, then, the service provider is equipped with servers that meet the requirements and provides relevant management and maintenance services. Compared with the first two methods, the cost of server leasing is reduced, which is especially suitable for small and medium enterprises and individuals with good economic bases.
4. virtual Host: this is currently the most common website space method. It uses special hardware technology to divide a server host on the Internet into multiple "virtual" hosts, used by multiple users. Each VM has an independent domain name or IP address. Figure 1 shows the virtual machine room. In this article, we will mainly introduce the selection, application, and maintenance of space in the form of virtual hosts.
5. Free Space: This is a preferred space for beginners in website construction. However, because it is free, it will be subject to many restrictions during use.

Selection of virtual host providers
Currently, there are many companies that provide virtual host services on the network, and the competition is fierce, do not be tempted by the low price of "Agent Price" or "internal price" of some unknown providers during the selection, so as to avoid being cheated. when choosing a space provider, it is generally necessary to examine its virtual host from the following aspects.
1. Stability. The stability of the server determines whether the VM can be opened normally or whether the website can be accessed normally. For servers with high configuration and good peripheral equipment, the stability standard is that the disconnection time of a year cannot exceed 10 hours, that is, the stable running time of a year should reach more than 2850 hours.
2. Security. Whether the space provider has installed a dedicated anti-virus software and network firewall for the server, and is equipped with dedicated staff to monitor the server 24 hours a day.
3. bandwidth and speed. Bandwidth is the guarantee of the website speed, and the server speed is determined by the bandwidth connected to each server. Here, we should pay attention to some advertisement advertisements with vague concepts of Space providers. Some advertisements only provide access bandwidth for one data center, but do not indicate the actual available bandwidth for each server, for example, if the entry bandwidth of a data center is 1 Gbps and 100 servers are stored, the bandwidth allocated to each server is 10 Mbps theoretically. If 500 servers are stored, the theoretical bandwidth of each server is only 2 Mbps.
4. Server Load balancer. Generally, when more than 200 virtual hosts are set up on one server, the performance of the server will be significantly reduced. If there are other sites in the middle to provide dynamic database query services, then the server's performance will drop more sharply.
5. After-sales service and technical support. To learn whether the Space Provider can provide timely and fast application processing and related technical solutions and services, to ensure that after the website is uploaded to the space, the site construction and maintenance provided by the provider and related Space Value-added services can be obtained.
Common virtual space parameters
After selecting a Space Provider, we also need to know some parameters involved in the space application process before applying for a space.
1. server operating system. There are often UNIX, Linux, and windows. In general, UNIX and Linux are more stable and efficient than windows, but the actual choice depends on the programming language of the website, if the website creation language is ASP or ASP. if the website creation language is CGI, JSP, or PHP, You need to select a Unix or Linux host. For pure static html space, you can select any operating system.
2. VM space size. The total space generally includes the web space used to store website page content and the log space used to store Website access log information. Some Space providers also provide free mailbox space of a certain size. If the website only provides simple information publishing functions, it generally takes only 50 MB or smaller host space, if you want to provide software download or media playback, more space is required. The specific size of the space depends on the actual size of the website.
3. network traffic. Some space providers can control the network traffic of virtual hosts. It is best to select a host that does not limit the network traffic. If the traffic is restricted, when the traffic volume increases, some users will not be able to access the website normally.
4. Number of IIS connections. Note that space providers use "IIS connections" to confuse "concurrent online users" to cheat space buyers. In fact, they are two completely different concepts. The number of IIS connections refers to the number of visitors accessing port 80, that is, the number of website files called. The number of concurrent online users is the maximum number of IP connections that the VM can accept. For example, if a browser opens 10 website pages at the same time, 10 IIS connections are generated, but only one online user is allowed. The number of IIS Connections cannot be the same as the number of concurrent online users.
Application
Apply for an instance for a VM
I want to apply for a VM for a blog website written using ASP. Here we take the Space Provider China channel as an example to introduce the specific space application process, so that you can draw a line from each other.
1. Register a member. First log on to the http://www.china-channel.com, under the "member self-service Management Center" click "Member registration" to enter the registration page, follow the page prompts to enter the relevant information, after entering the complete, click the "Registration" button, when you submit a page with "congratulations", you are successfully registered and your membership number is displayed on the page. Go back to the homepage and log on to the "China channel membership management system" with the member number and password at registration.
Tip: After registering a member, you can not only apply for a host, but also apply for domain names, professional post offices, website promotions, and other services provided by the host provider.
2. Apply for a VM. In the "China channel member Management System" Hall, click the "VM" link in the menu bar to go To the VM self-management page. Various types of hosts with different operating systems and space sizes are provided, before formally applying for a host, you can click the "virtual host trial" button to get a free 7-day trial of 10 MB host space to test the host performance and network speed of the Chinese channel.
Go back to the VM self-management page, and click "details" after the space model to view the detailed parameters of this host, if you are satisfied with the parameter configuration, click the "Activate now" button to enter the specific host application interface. If you have not applied for a domain name for the website in advance, you can also select "register a new domain name" to apply for a domain name for the website. If you already have a domain name, select "use existing domain name" and enter the domain name after "Domain Name, click "Next" and the relevant domain name, post office, price information, and FTP account of the VM will be displayed. After confirmation, you can click "OK, the system will automatically deduct the host registration fee from your registered account, and then activate the host service for you in real time.
Tip: You can use the post office remittance and online payment methods to recharge your registered account. When you send funds through the post office or bank, note that your registered member number must be indicated in the message.
After the VM is activated, you can upload the web page to open the website to the outside world. However, all space providers will prohibit users from using the VM to engage in illegal activities on the Internet. Once the website is found to be unhealthy, the Space Provider will delete the website, and the website may be handed over to the relevant department for handling in serious cases.
Maintenance
Management and Maintenance of Virtual Hosts
After the virtual host is activated, in addition to the hardware maintenance and software maintenance provided by the Space Provider, we also need to perform some necessary management and maintenance for website operations.
1. timely renewal. Virtual Hosts are generally paid on a yearly basis. For the continuity of host usage, we should try our best to renew the host in advance so as not to forget the renewal and affect Website access. Generally, the Space Provider will send a renewal email notification in advance.
2. view the space remotely. To prevent excessive data upload caused by insufficient host space, we try to understand the use of space, the use of flashfxp can monitor the host space at any time (: http://www.skycn.com/soft/689.html ). Run flashfxp, connect to the remote Vm, and run "Tools> computing FTP space". In the displayed dialog box, click "check" to scan the website directory, after scanning, a space in use is displayed.
3. Modify the FTP password remotely. To securely use ftp to upload webpages, we generally need to modify the default FTP password provided by the Space Provider. Open the "command prompt", enter FTP ftp.yourname.com (FTP domain name), enter the FTP user name and default password as prompted, and then enter: "quote" site pswd default password new password "" to change the password.
