IT Infrastructure 001: Hosting Services

This is a piece I have written for my workplace sometime back. The department was having difficulty communicating the options available for business units to host their applications and enterprise software. In the end, we decided to keep to 4 simple options, presented to the business units as services that they can choose from.

A wide range of hosting services had emerged over the years, driven by advancement in technology and increasingly demanding business needs in a competitive environment.

As a result, implementing a new application is no longer a simple task. Aside from designing the functionality of the application, businesses will also have to decide on a hosting service to host the application. The choice of hosting service will have a critical impact on the performance, sustainability and the overall costs of the implementation.

From a technical point of view, all hosting services provide the following foundations to ensure the hosted application runs smoothly:

  • Datacenter facilities
  • Servers and Hardware
  • Networking
  • Management of the above

The IT Infrastructure of a company should strive to provide their knowledge and expertise to help businesses make better informed decisions. To do this better, the team can consider the following classification of all hosting services available in the market, when they are organising and presenting information to their business partners.

The business will provide a space on-premise to install the datacenter facilities and hosting resources. Hardware, network and management will be provided by IT Infrastructure team or any partner vendors. The business will have full control over the application.
