Cloud Computing Models for Smiths Security: Assessment Report

This report focuses on cloud computing models and their practical application within Smiths Security, a company with diverse security businesses across Australia. The assessment analyzes the current IT infrastructure, including Active Directory, SQL Server, Lotus Notes, Print Server, and IIS Web Servers, and evaluates the benefits of migrating these systems to the cloud. The report explores Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) models, detailing how each can be applied to Smiths Security's specific needs. IaaS is considered for migrating Active Directory and SQL Server, PaaS for IIS Web Server integration, and SaaS for the print server. The report emphasizes cost-effectiveness, security, mobility, loss prevention, software updates, and sustainability as key drivers for cloud adoption, referencing relevant literature to support the analysis. The report highlights how cloud computing can modernize and streamline the company's IT operations.

CLOUD COMPUTING
Smiths Security

MAIN CONCEPT
 Cloud computing refers to delivery of various
computing services such as storage, servers,
networking, database and many more
(Rittinghouse & Ransome, 2016).
 It is known as cloud computing as the
information is found in “cloud”.
 Information is saved in a remote database.
 These services are provided by cloud providers.

REASONS TO SWITCH
 Cost effective.
 Security
 Mobility

 Loss prevention
 Software updates
 Sustainability

MODELS OF CLOUD COMPUTING
 Infrastructure-as-a-service (IaaS)
 Platform as a service (PaaS)
 Software as a service (SaaS)

IAAS
 IaaS suppliers provide a virtual server as well as
storage (Kavis, 2014).
 IaaS can be used to migrate Active directory into
cloud.
 With the connectivity of IaaS, a Virtual machine can
be created in the environment (Caballer, Blanquer &
Moltó, 2015).
 IaaS would also be helpful in migrating SQL server to
cloud.

PAAS
 PaaS is suitable for migrating IIS web server
into cloud (Varadharajan & Tupakula, 2017).
 PaaS provides better security to the web
server.
 It would help the organization to reduce cost.

SAAS
 SaaS solution is most helpful for
integrating print server in cloud.
 Cloud printing provides better
administration and oversight (Coutinho,
de Carvalho Sousa & Rego et al., 2015).
 It is much more affordable.
