15. Shared hosting
Cheap
Appears to offer a complete package
No sysadmin skills required
Multiple points of failure
Lack of support
Lack of control
Risk of poor performance

16. Virtual Private Server
More Control
More Reliable
Usually requires self-management, and therefore deeper
sysadmin knowledge
Easier to break if you don’t have the skills, but this can be
outsourced
Other virtual servers on your server may disrupt your service (e.g.
bandwidth)
Single point of failure (it is still only one server)

17. Dedicated or Co-LocationDedicated or Co-Location
Complete Control
Guaranteed Reliability through SLAs
External data security risk mitigated through SLA
Corporate Governance risk mitigated through SLA
Expensive
Single point of failure
Sysadmin skills essential unless the server is under
a managed contracttill only one server)

18. Clustered Servers (aka Private Cloud)
Complete Control
Guaranteed Reliability through SLAs (if outsourced)
No Single point of failure
No external data security risk
Corporate Governance Assured
Very Expensive
Sysadmin skills essential unless the cluster is under a managed
contract

19. Public Cloud
Less Expensive
Fully managed by a third party, meaning better reliability
No performance issues – it scales as needed
So large that external factors may affect your site and may take a
long time to resolve
Difficult to assess external data risks and corporate governance
issues
