Enterprise websites include very popular marketing and media sites, as well as social, travel, and other application-heavy websites. For example, Lamborghini, Coursera, and Nordstrom use AWS to host their websites. Enterprise websites need to dynamically scale resources and be highly available to support the most demanding and highly trafficked websites.
VPS Hosting: A virtual private server (VPS) setup is like a shared hosting setup on steroids. It generally uses more powerful hardware and takes its name from the fact that while multiple websites are being stored on the same physical hardware, each uses virtualisation software to allow them to operate independently as though they were dedicated mini-servers.
A domain name, is like the address of your home; web hosting on the other hand, is the space of your house where you place your furniture. Instead of street name and area code, set of words or/and numbers are used for the website’s naming’. The same goes with hosting, computer hard disk and computer memory are used instead of instead of wood and steel for storing and processing data files.
If industry-leading uptime and rapid-scalability are your two biggest concerns, cloud hosting might be just what you're looking for. Cloud hosting will get you access to a cluster of servers from which you can quickly provision resources when you need them. Along with having enough separation from unruly neighbors, your application should be kept safe. VPS and Cloud services are sometimes combined into a hybrid service called Cloud VPS or Scalable VPS.
The availability of a website is measured by the percentage of a year in which the website is publicly accessible and reachable via the Internet. This is different from measuring the uptime of a system. Uptime refers to the system itself being online. Uptime does not take into account being able to reach it as in the event of a network outage. A hosting provider's Service Level Agreement (SLA) may include a certain amount of scheduled downtime per year in order to perform maintenance on the systems. This scheduled downtime is often excluded from the SLA timeframe, and needs to be subtracted from the Total Time when availability is calculated. Depending on the wording of an SLA, if the availability of a system drops below that in the signed SLA, a hosting provider often will provide a partial refund for time lost. How downtime is determined changes from provider to provider, therefore reading the SLA is imperative. Not all providers release uptime statistics. Most hosting providers will guarantee at least 99.9% uptime which will allow for 43m of downtime per month, or 8h 45m of downtime per year.
Almost all the services offer some sort of page builder that makes it easy to drag and drop 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.
