Software as a Service
This is about using software hosted and run by a 3rd party rather than running in-house and on your own equipment and infrastructure.
Can be good where:
- Don’t want capital outlay – pay as you go
- Easy access from different sites
- Less in house IT support
- 3rd party responsible for backups and recovery
Examples of well know SAAS
- Microsoft Office 365
- Amazon Web Services
- Google Apps
- Docusign
- Ransomware (unfortunately!)
Considerations:
- Data Security
- Reliability and speed of internet connections
- Robustness of 3rd party backups and DR plans
- Lack of control over timing of upgrades
- Ability to move away
