Google is amazing. You know more about google, you will find more ways to strength your website. Now I would like to share my experience: Host your domain on google platform ( GOOGLE APPS + GOOGLE APP ENGINE ). The website hosted on google platform is more secure and more fast.

1. You must have a domain name and get a web hosting for the website. You can register a free domain name from http://www.youdomain.co.cc .  Or you can cost only $10 to register a yourdomain.com from godaddy or hostmonster and buy a web hosting from them too(normally US$5 per month)

2. Sign in Google Apps Standard Edition by using yourdomain. Google apps needs to confirm you own the domain, so you need to upload a specified txt file to the root directory of your site. After the confirmation, everything is OK. If you want to get free e-mail hosting supported by google, you just need to change the MX RECORD toASPMX.L.GOOGLE.COM.

3. Sign in to Google App Engine with your Google Apps account, use the following URL:http://appengine.google.com/a/<YOURDOMAIN.COM>/Sign in Google App Engine. After sign in, you need to fill your mobile no to receive a six digits confirm code from Google. After that, you will

create an application, such as: xxx.appspot.com . You can add at most 10 applications.

4. After creating the application, back to the dashboard of google app engine, click versions

5. Click Add Domains and input yourdomain name, then you will be taken into google apps automatically

Then click Add new url: add your subdomain name ( xxx.youdomain.com ) or your top domain name( www.yourdomain.com )

6. Go to the cpanel of yourdomain, add a new CNAME to GHS.GOOGLE.COM. Now your domain name/subdomain name was mapped with xxx.appspot.com .

By this way, my game site  http://freewebgame007.appspot.com powered by google app egnine.  You can try it.
