Personal web server

• as a computer appliance
• as a general-purpose server, such as a Linux server, which may be located at the owner's home or in a data center
• in a shared hosting model, where several users share one physical server by means of virtualization, or virtual hosting.
• as one feature of a computer that is otherwise also used for other purposes.

Advantages

• Privacy: as the personal server is owned by the individual that derives the main benefit from it, they are in control of who else may access information on the server
• Autonomy: the owner of the personal server decides which applications to run on the server, whom to allow access to, when to upgrade, etc.
• Hackability: the owner of the personal server can configure and change any aspect of the personal server

  Disadvantages

• Administration overhead: the owner of the server is responsible for system administration
• Higher power consumption: the power consumed per user is higher, on average, than in a model where many users use the same server, such as in the SaaS/cloud model.
• Poor scalability: the server may function poorly or crash if its resources are heavily accessed
