WordPress is the platform of choice for large and notable companies, including TechCrunch, the New Yorker, and BBC America, and it has even supported powerful global movements. Now powering roughly 27% of the internet, WordPress is far and away the most popular website-building and management software. Because WordPress is such a popular choice, most, if not all, web hosts will offer integrated WordPress as a feature.
Hosting that is aimed at specific CMS platforms and tweaked optimally for them: e.g., WordPress hosting, Drupal hosting, Magento hosting, etc. In these cases, the best hosts do far more than just provide the minimal requirements for those platforms. They provide a rich, and fully managed environment so your site can perform like a well-tuned machine.
Web hosting services offer varying amounts of monthly data transfers, storage, email, and other features. Even how you pay (month-to-month payments vs. annual payments) can be radically different, too, so taking the time to plot exactly what your company needs for online success is essential. Many of these companies also offer reseller hosting services, which let you go into business for yourself, offering hosting to your own customers without requiring you to spin up your own servers.
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.
