Web hosting services vary regionally because of latency, cultural differences and variations in currency. For example, web hosting services in most of the States in the U.S. are not subject to any additional indirect tax, such as a sales tax or a service tax – when you checkout. India, on the other hand imposes a service tax, on online sales of web hosting.
In India, most of the web hosting market is dominated by businesses in the web designing industry. Most businesses would approach a designer to design a website and the designer would pick the hosting provider and the domain name provider. Businesses generally do not pick the hosting and domain name provider in India.
On the other hand, in the US the business would generally buy a domain name itself from either GoDaddy or something of the sort, and either make a working website in house online, or hire a designer after the domain name has been bought. This is primarily because businesses are more tech savvy in the US, as compared to smaller emerging markets such as India.
China on the other hand is very language sensitive. If your website is not in Chinese, you’re probably not going to have any Chinese customers. China is so language and region specific that even most of their search traffic comes through Baidu, and not Google.
Europe on the other hand, is more open and integrated with English generally. Europe obviously has its regional variations like different rates of tax in different countries and different legal requirements. They also have different pricing for their country specific TLDs but its relatively open like the US, and the UK.
