Cloud Computing: Models and Office Automation Analysis Report

This report provides a comprehensive overview of cloud computing, examining various models such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It delves into the architectures and components of cloud computing, comparing and contrasting the approaches to office automation, including office portal and centralized database approaches, and analyzes their benefits and issues. The report also discusses the differences between IaaS and PaaS in a public cloud setting, offering recommendations on when to use each model. Furthermore, it recommends the SaaS model for SharePoint services, highlighting advantages like reduced implementation time, lower costs, and seamless integration and scalability. The report concludes by addressing potential problems related to the recommended model and suggests strategies for mitigation, providing a well-rounded analysis of cloud computing concepts and their practical applications.

4CLOUD COMPUTING
Notes: The concept of cloud computing in recent times is one of the technological innovation,
which is driving the aspect of manipulation of the data. The main advantage, which can be
achieved from the concept of storing the data at a place, which would keeping, the data
secured and can be retrieved when required. There are different model, which are involved
into the concept like the software as a service, platform as a service and infrastructure as a
service. The model can be implemented according to the requirement of the organisation.
Slide 3
Note: In the past the people usually used to run program the application from the concept of
the software's which were downloaded on physical sever or computers . Cloud computing
allows any organisation to access the same type of software or program not through the
traditional system but also through the concept of the cloud.

Slide 4
Note: Various components relating to the cloud architecture mainly include resources, which
are on premise, software components and relating services, cloud resources and middleware.

Note: Apart from the above stated architectures, another architecture, which exist, is the DaaS
which is the development as service which provides the user with the direct application which
is based on the development tools which is connected to a shared community.

Note: Some of the providers of the cloud provide full-fledged cloud architecture, which is
private. One such offer, which is provided, is Enomaly, while the concept of Eucalyptus can
be considered as an open source variant that has majorly gained attention.

Question 2
Approach of Office automation
The two approach, which can be implemented by the regional garden in order to
automate the office, are the office portal approach and the centralized database approach.

9CLOUD COMPUTING
Office portal approach: one of the approach, which can be implemented by the regional
garden, is the office portal approach. In this approach, every staff would be given a different
user name and password by which they have to log into their account in to perform their duty.
Automation system: It can be considered as one of the most effective solutions for the
automation of office, which can be implemented over the infrastructure, which already exist
in the framework of the business. It can be utilized for the concept of messaging which can be
very much beneficial for the working from the point of view of the workers. Most of the
organization who have installed the system can benefit a great advantage from the concept. It
is very much known for Lessing the work burden and ensures that the workers work in office
in a peaceful manner.
Benefit and Issues of each Approach
Benefit in Office portal approach
The main benefit, which can be achieved form the approach, is that every individual
staff would be having a separate identity and different log in user name and password. The
concept would restrict other people the unauthorized user to get the access to information,
which they should not be allowed to access. Information can be made very much secured by
means of implementing the approach.
Issues in Office portal approach
The office portal approach can be considered a single point access for every staff. If
by any means the user name and the password were misplaced by the concerned person the
access to their own individual portal would not be possible. It should be taken into
consideration that the individual staff keep the possession of their individual user name and
password to themselves only (Oliveira, Thomas & Espadanal, 2014).

10CLOUD COMPUTING
Benefit of Automation system
Installation of the office automation system would be very much beneficial in
reducing the work of the staff. It directly involves handling the work pressure quite easily and
enjoying the work pressure. It can give benefit in the field of multitasking, which is needed in
every organization.
Issues in Automation system
The automation system can be considered to be on the higher end of the cost due to
the aspect of many advantages, which it can give to the organization and its staff. It is a
technical approach, which cannot be handled by many people due to the factor that they are
more inclined to the traditional way of working. In most of the cases, it can be seen that for
the individual training would be required and this may be considered to be very much time
consuming. In this approach there is no manual methods so this can be stated as one major
disadvantage of the process.
Recommendation
The devices, which can be used, for the concept of office automation which are stated
above the device, which would be recommended, would be the automation system. The
system is recommended due to the factor that the existing infrastructure would not be
changed and it would be placed over it. It would be enhancing the features, which can
expected from the system.
Question 3
Difference between IaaS and PaaS in public cloud
The infrastructure as a service uses the concept of virtual machine to house the data
rather than achieving the concept of physical room of server that directly takes tons of space

and energy. The Virtual machine in this context is nothing but the server of someone else,
which is used and paid accordingly for the service. In addition to the server concept, the IaaS
provides some scaffolding development for example operating system, networking and the
concept of storage. Companies, which take the option of moving towards the concept of the
cloud, can use the space of the public cloud that the company share securely with other
companies or a private cloud, which directly isolates the data in the particular server or a
combination of private and public cloud, which can be referred to as a “hybrid cloud”.
The Platform as a service can be referred to as a platform for the organization. PaaS
provides a solution for the concept of coding language, which can be used for the purpose of
communication with the server, and the data base device of storage. The PaaS can be
designed to help the internal developer test, build and iterate their own software’s.
The main difference between the concept of SaaS and PaaS can be explained
according to the usage and the aspects, which can be offered with its implementation.

When to use the models.
PaaS
When an organization has the need of resources and time relating to building up of
software but they do not want to mess with all the nuances of building the server, managing
the database and networking. The concept of the PaaS will directly store the information
along the side of the user, but the features of the security like the concept of the
containerization and encryption will keep the data secured and separate (Almorsy, Grundy &
Müller, 2016).
IaaS
When an organization needs to customize the underlying software or hardware of the
application or have specific concerns regarding the security that require an isolated database
or private cloud (Rittinghouse, & Ransome, 2016). An individual can find all the points of the
spectrum from private to the concept of the public cloud even with the modules of support
that blur the lines between the PaaS and the IaaS.
The choice between the concept of the PaaS and the IaaS comes down to the internal
resources and the knowledge of the institution and a bit of look into the concept of the
regulatory environment. The organization who directly adopt the concept of the SaaS are
those that need to invest in the time in the process of development but do not have the
resources. When the need of increased security and higher level of customization should take
into consideration the IaaS before they buy the sever firm. Most of the organization
implement the different software’s according to their own specific requirement. In recent
times, the software’s are implemented and advantage are gained from the concept (Oliveira,
Thomas & Espadanal, 2014).
