For packages supporting unmetered disk space or data transfer (bandwidth), we do not have defined limitations. These resources are "unmetered", meaning you are not billed according to the amount of disk space or bandwidth used. While of course these resources are not infinite, we believe our customers should have all the resources necessary to build an online presence and 99.95% of customers will have more than enough disk space and bandwidth to meet their needs.
If you do need to upgrade, be ready to pay for it: The cheapest VPS hosting packages start above $10/month, and can stretch beyond $50/month depending on how much storage space you need. Dedicated servers are more flexible, but are even more expensive, starting at $100/month. Hopefully your website will be paying for itself before you need that kind of power.
The host may also provide an interface or control panel for managing the Web server and installing scripts, as well as other modules and service applications like e-mail. A web server that does not use a control panel for managing the hosting account, is often referred to as a "headless" server. Some hosts specialize in certain software or services (e.g. e-commerce, blogs, etc.).
Web hosting is a service which allows websites to be published to the internet and hosted so they are accessible on the around the world on the World Wide Web for everybody to find. Web hosting companies buy or lease many servers in a data center which are connected to the internet, and sell partitioned space on the server, typically called Shared web hosting. This allows website owners to pay a small monthly fee for the hosting space as the cost is spread across many other websites hosted on the same server.
With a shared hosting plan, you are renting space on a server that you share with other website owners. This also means you're sharing resources like bandwidth, memory, and processing power. This can be a problem, because a web host company typically supports hundreds, even thousands, of websites on a single server. Most of these websites will get very little traffic, allowing those who do see higher levels of traffic to use the resources they need. Nevertheless, there are no guarantees that you will get the resources necessary to support your website.
