Haha, now that you've opened this article, I guess you're a web developer. Although the development of the site than to consider the host aspects of the problem more interesting, but the host choice is indeed a very important thing, not hasty decision, otherwise endless.

This article pointed out 20 in the selection of Web site host must pay attention to the problem, I hope to help you.

1 volume

When choosing a host, the first thing you think about is "how much data can I store?" For the vast majority of small and medium-sized sites, there are a few g capacity is enough. Some host providers provide "unlimited space" host (mainly foreign host), which is actually deceptive. Carefully read their terms of service, they tend to say: yes, we provide unlimited capacity of the host, provided that you must be a "normal" site. But what is a normal web site? That's not up to you. So still choose to set the capacity of the host is more secure.

In addition, it is important to note that some of the domestic host is the database capacity and web space capacity of the calculation separately, must pay attention before purchase.

2 Bandwidth (flow)

Bandwidth is sometimes called flow, and capacity two concepts are easy to confuse. Capacity refers to the hard disk space you have, such as 100MB, you can only store 100MB of Web pages, data or multimedia files. Bandwidth refers to the total amount of user uploads/downloads that your host allows in a certain period (usually one months). For example, your host has a 1MB Web page, when users view this page 1000 times, resulting in 1G traffic (bandwidth).

If the capacity is full, it is no longer possible to upload new files. But if bandwidth is depleted, the host will stop visitors from visiting your site until the next month's bandwidth is zero. So you have to keep an eye on bandwidth consumption and redundancy in bandwidth choices to cope with traffic outbreaks.

3 Domain name/subdomain number

For many novice users, they only build a website, 1 domain name is enough. But they won't be able to build more sites in the future, or open subdomains under the current site. So as far as possible to choose to allow the binding of multiple domain name/subdomain host, to leave room for future development.

4 Email accounts and functions

Many host operators to provide users with email account functions, you can use your own domain name to create mailboxes. If you want the host to provide this feature, then you need to pay attention to the number of accounts allowed to create, whether there is an online email control Panel, whether with Gmail and whether to support POP3 letters and so on.

Of course, you can also choose Google Enterprise Suite, Tencent domain name mailbox and other free services, their quality of service is often more reliable than the host provider.

5 Database Support

Now on the Internet, there are database support behind the small web site. Most hosts support MySQL databases, but if you are using PostgreSQL, Oracle, SQL Server, or other databases, make sure your host is supported.

6 Framework support and one-click installation

Many foreign host providers to provide popular framework, blog system, CMS, a key installation function. This is very useful for beginners, but if you are an old hand, you may not have much value.

7 mobile app or website

Do you want to be able to manage your site through your mobile phone and view Access data? If the host provider provides mobile apps, this is easy. Unfortunately, only two of media template and Slicehost have launched apps that support the iphone and Android. But I believe this is a trend, and other hosts will follow.

8 Technical Support

Very, very important! Be sure to find out what technical support your host has: is there a customer service phone? Do you support email customer service? Is there a ticket system (not common in China)? How long will it take to answer the question?

9 Shell Access

This is an advanced feature that only professionals can use. Shell access allows you to manage hosts in a command-line way via SSH: secure copy, delete files, fast change file permissions, perform multithreaded tasks, and more.

htaccess file Support

The. htaccess file allows the Apache server to handle URL rewriting, simply saying it can help you create clean url,wordpress, Drupal, discuz These famous build systems need to be used. You can also use it to add passwords to folders, redirect pages, and so on.

One Cron jobs (scheduled Task)

Cron allows a host to perform a specified task at a specified time, such as "regenerate the page cache every 8 hours" or "email every 3 days to an unregistered user", which requires cron support. Cron is always a good thing, and hosts that support shell access generally support cron.

12 Programming language Support

This is actually not a special mention, but now some hosts support a variety of programming languages, such as the Mint host to support PHP, Perl and Ruby. Of course, if you only use PHP in one language, this will not be considered.

13 Free AdWords

Some foreign host chambers offer Google AdWords advertising quotas (usually 50$) or other forms of advertising. It's better than nothing, right?

14 Site Backup

Do not assume that the data stored on the server will be more stable than your own computer, and the server will fail to crash and cause data loss. Remember, the server is a large computer that everyone can access. Be aware of what data backup strategies the host provider provides. If the host provider does not provide frequent backups, then you need to consider your backup strategy.

15 Operating system

For most people, this is not a problem. Unless you're using asp.net, you'll have to look for Windows servers, and other times, the Linux system's OS is the mainstream choice. But the domestic situation is not the same, piracy makes Windows operating system server as much. Note, however, that shell access,. htaccess, mentioned above, are supported by only the Linux system servers. I met a lot of friends, using the Windows+iis server, the. htaccess does not support, resulting in WordPress link problems.

16 Additional applications

The "one-click Installation" mentioned in article 6th is actually an application outside of the host service. Perhaps you also need a mailing list, access analysis and other related programs, then pay attention to it.

17 latest version of the server program

If possible, try to find software installed is the latest version of the server. Some service providers software update is not frequent, such as all this time the server running or PHP4, that can be a cup. In addition, the timely updating of the software is also a good way to prevent security risks.

18 Online rate (uptime)

I don't say you know the importance of online rates. Be sure to choose a good reputation of the service providers, their online rate is often more secure. However, 100% of the online rate is also impossible, be sure to read the service provider commitment to the online rate, and tools for monitoring. The pingdom I introduced earlier is a good tool for monitoring online rates.

19 Free Domain Name

Some hosts give free top-level domain names, which is a good thing for users who do not have a domain name. But note that there is also a trap, once the use of host domain name, if you want to refund, the host will be the domain name of the money alone buckle down.

20 Virtual host? VPS or exclusive server?

Virtual Host, VPS, dedicated server, each has its own advantages and disadvantages. Here no longer detailed analysis, you can see I wrote an article, which made a careful analysis.
