Put simply: unlike traditional webmail which is supported by advertising, email hosting is an ad-free service designed for small to medium-sized businesses, as well as individuals with high demands who wish to set up a more robust email service. In addition to providing users with comprehensive support, email hosting also features increased capabilities such as storage, security, and data recovery.
Almost all the services offer some sort of drag-and-drop website builder that makes it easy to drag and drop items to build your page. These are great for getting started, but they often lock you into the service. Most page builders are proprietary to the service, or don't create HTML that's portable enough to be easily moved to another service if you decide it's necessary.
Unlike shared or VPS hosting, dedicated hosting makes your website the lone tenant on a server. To extend the housing metaphor, having a dedicated server is like owning your own home. The means that your website taps the server's full power, and pays for the privilege. If you're looking for a high-powered site—an online mansion for your business—dedicated hosting is the way to go. That said, many dedicated web hosting services task you with handling backend, technical issues, much as homeowners have manage maintenance that renters generally leave to their landlords.
Many web hosting services offer a low "starting price," but require you to prepay for two or three years of service to get that price. After the promotional period, the renewal price for some web hosting services can be two, three, or even four times the initial promotional pricing. While the initial deal might be incredible, the cost of transferring your site (or paying the added fee) in a couple of years may be something to consider.
It shouldn't come as any surprise that, like other web host providers, A2 Hosting's unlimited plans aren't actually unlimited. It expect you to use its service like "similarly situated customers." This is like being on a highway. If everyone is going a few miles above the speed limit, you're probably okay, but if you're barreling down the fast lane past everyone else, you're probably going to be asked to slow down.
On the topic of dedicated hosting, many web hosting services also offer managed hosting. This type of hosting sees the web host act as your IT department, handling a server's maintenance and upkeep. This hosting option is something that you'd typically find with dedicated servers, so it's a business-centric addition. Naturally, it adds a few bucks to the hosting cost, but nothing that should break the bank if you have the resources for a dedicated server.
When it comes to server operating systems, Linux is typically the default option. Still, some services offer a choice of Linux or Windows hosting. If you have specific server-side applications that require Windows, such as SQL Server or a custom application written in .NET, then you need to make sure your web host has Windows hosting. But don't let the idea of a Linux host intimidate you. Nowadays, most web hosts offer a graphical interface or a control panel to simplify server administration and website management. Instead of typing at the command line, you'll click easily identifiable icons.
