Onsite Versus Offsite

This lesson covers the difference between onsite and offsite, meaning is a service hosted on site or ‘in cloud.”  When services are onsite:

  • There is faster response time and more control
  • Business continuity can be affected if there are problems with the building (e.g. a power failure)
  • It can be pricey to keep staff on site to work on the web server

When services are off-site:

  • It can be more economical to manage a company web server
  • Allows for business continuity in case of something like a power failure
  • A great resource for backing up a lot of data
