Bandwidth is a measurement of how much data (information) can be transferred over a set period of time; for instance every time someone looks at a page / image on your website this increases your bandwidth use. The average hosting company offers between 1Gb (1024 Mb) and 5Gb a month, which should be plenty if the site isn't going to be another “Amazon”. So the calculation for the bandwidth would be the size of the pages/images viewed by each visitor times how many visitors per month. Some packages do not set a limit on the amount of traffic to your site.
An important consideration while selecting a web hosting Company is the infrastructure facilities, the flexibility and the support provided. Most hosting providers have contracted for bulk space from a data center and offer bundles of shared space to you. The infrastructure of the data center is an important consideration. What is the bandwidth available to the data center? Does it have redundant provisions for its connection to the Internet? What is the security provision including that for fire safety? What has been the track record of the service provider and the data center?
There are two primary options for hosting your site on a Server. You can have a dedicated server or you can rent space on a shared server. In the case of the shared server, the main server holds several websites, including yours. A shared server turns out far more economical to you. If your site has extensive transactions, important security considerations and you want much greater control over your site, you may consider having a dedicated server. Several institutions and large companies may even host their websites on their own internal and dedicated server, which is then exposed to the Internet.
One of the most important aspects of a paid subscription site is the database to store and retrieve information; the two most common database systems are MySQL and Microsoft Access - which one you use will depend on your application and your host. The other options for selecting a database are Microsoft SQL Server, Oracle, DB2, Sybase and several others. Selection of the database is an issue that has to be decided with your Developer. The factors are compatibility with your web application and interfaces and your hosting platform, scalability, robustness and reliability and costs. If your database platform has been decided, ensure that this is offered and supported by your web-hosting provider.
