 Smith Security has Active Directory domain controller on
Windows Server 2003.
 Windows Server 2003 running IIS Web servers, which connect to
the SQL backend (Fernando, Loke & Rahayu, 2013).
In this case, IaaS would be the best solution, since it will be
providing virtualized infrastructure.

 Smith Security Ltd also has other server
infrastructure like Lotus Notes email server and 2
Business Application Servers running custom software
to manage their staffs (Hashizume et al., 2013).
In this case, PaaS would be better for them since the
server are running custom software.

 Smith Security Ltd. has server infrastructures of Windows
Server 2003 Print Server and SQL Server 2003 database server
on Windows Server 2003 (Fernando, Loke & Rahayu, 2013).
However, SaaS is not suitable in this case, since the servers
are running custom software.

The recommended cloud model for Smith
Security Ltd is IaaS or infrastructure as a service.
Although, the cost is high, IaaS is extremely safe
and secured and thus there is no chance of data
loss. Moreover, it helps in easy collaboration.
