Choosing is simple: select hosting that will support the script, platform, or CMS you want to use. And if you aren't sure, go for Linux hosting. For example, WordPress will run on Linux and Windows, but hosts generally recommend that you run it on Linux. However, if you want to use a Windows-specific technology like ASP.NET, you'll need a Windows host.
Cloud Hosting: Cloud hosting allows webmasters to tap into a large bank of servers that are all interlinked and designed to take over from each other if needed. In other words, if you need more resources, the cloud will provide more resources to rise to the demand. Cloud hosting is usually the best option if you want to aim for 100% uptime and don’t care how much you need to pay for it.
Website hosting is typically measured in the amount of disk space you're allotted on the server and the amount of data transfer or "bandwidth" you need for accessing the server. For example, if you have a lot of customer interaction at your website, such as files to download, you will access the server frequently and you'll need more Web hosting transfer space than someone who simply puts readable text on their website. The more "items" or "content" you have on your site (i.e., photos, maps, PDF files, etc.), the more disk space you'll need for website hosting.
Make sure your Internet service contract allows hosting. Many Internet service providers (ISPs) expressly forbid personal hosting unless you have a business plan, which often costs significantly more than a standard use plan. This shouldn't be an issue if your site only generates a few hits per month, but any kind of significant traffic will draw attention to your hosting.
Moving to another website consists of transferring the website’s files and databases, configuring your site with the new host, and directing your domain’s DNS to the new host. Once you pick a new site host, they can usually help you out with this process. The cost will depend on the host you’re switching to, but it will probably be anywhere from $150-$400.
