Shared hosting is Web hosting in which the service provider serves pages for multiple Web sites, each having its own Internet domain name, from a single Web server. Most Web hosting companies provide shared hosting. Although shared hosting is a less expensive way for businesses to create a Web presence, it is usually not sufficient for Web sites with high traffic. These sites need a dedicated Web server, either provided by a Web hosting service or maintained in-house.
What are the pros and cons of shared web hosting?
Some of the benefits of shared web hosting are as follows:
- Cost is shared through all clients using the server.
- Ability to utilise most non-specialist software packages (e.g. PHP, MySQL, .Net etc.)
- Use of your own domain names and email accounts.
- Good server administration.
- Allowing someone else the hassle of looking after the server.
- No specialist website and server administration knowledge required.
Some of the drawbacks include:
- Resource limitation – everybody uses the same memory, CPU, Hard Drive and IP address.
- Lower security levels, for example, you don’t have your own firewalls.
- You can use only the software provided by your hosting company and naturally can’t install your own.
- Sharing your IP address with sites that can be problematic or become blacklisted.
