Slide Note: Infrastructure as a service or IaaS provides virtualized resources including the
hardware, storage and servers for storing an accessing the data from cloud. This is the most
secure infrastructure solution. In this approach, the client does not need to buy a new
infrastructure but can leverage the infrastructure provided by the cloud vendor.

Slide Note: Platform as a service could have been the best choice for Regional Gardens, had its
architecture not become almost obsolete. The existing infrastructure may not be used by
Regional Gardens and therefore, IaaS approach is chosen. Although implementation of IaaS will
be costly, it will provide an integrated business operation for Regional gardens. The staffs can
easily access the data stored in public IaaS with the help of internet and a web browser.

The choice of IaaS approach is done after evaluating the condition of the existing architecture
and the need of Regional Gardens. Platform as a service or PaaS is used for deploying the cloud
services. This could have been a good option for Regional Gardens if the existing infrastructure
was up to date. Instead of PaaS, the IaaS option is therefore chosen or Regional Gardens as it
offers extreme flexibility and scalability in storage and access of data.

automation. Two approaches of office automation are therefore suggested for Regional
Gardens after evaluating the needs and the requirements of the organization. The two
approaches of office automation are as follows-

The office automation system to be developed for Regional Gardens should provide the
staffs of the organization accessibility to the different services such as email, word processing
and spreadsheet capabilities. The two approaches of cloud automation include choosing an
integrated approach whose back bone will be a Local Area Network or LAN and a cloud
approach.
2.1.1. Integrated Approach
In this approach, the different office automation services such as electronic
communication, electronic collaboration, office management and so are connected together
using a LAN. Therefore, a local area network provides the backbone for this type of office
automation and therefore, it is capable of providing a integrated and automated services to the
staffs of the organization.
2.2.2. Cloud Approach
