Analysis of Cloud Computing Architectures for Regional Gardens

This report focuses on cloud computing architectures suitable for Regional Gardens, evaluating Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The analysis begins with an overview of cloud computing, its advantages, and different types of cloud architectures. The report then delves into the specifics of IaaS, PaaS, and SaaS, discussing their functionalities, benefits, and applications. It considers the current infrastructure of Regional Gardens, which includes Windows Server 2008 R2 and 2003, SQL Server, and Exchange 2007. Based on this analysis, the report recommends IaaS as the most suitable cloud infrastructure for Regional Gardens, highlighting its flexibility, scalability, and cost-effectiveness. The report also includes a list of relevant references to support the findings.

CLOUD COMPUTING ARCHITECTURE

Cloud Computing
 Cloud Computing is a computing service that
depends on computing resources that is
shared.
 Cloud Computing do not have personal
devices or local servers for handling their
applications (Sadiku, Musa & Momoh, 2014).
 Clouds computing generally take the cloud
service and then move all the data to a
firewall outside the organization.
 The application storage and all others
services are accessed through the Web.

Advantages of Cloud
Computing
 Flexibility
 Disaster recovery
 Automatic software updates
 Capital-expenditure Free
 Increased collaboration
 Work from anywhere
 Document control
 Security
 Competitiveness
 Environmentally friendly
(Source: Bruneo, 2014)

Types of Cloud Architectures
 Software as a service (SaaS)
 Development as a service (DaaS)
 Data as a service (DaaS)
 Platform as a service (PaaS)
 Infrastructure as a service (IaaS)
The architectures that can be useful for
Regional Gardens are IaaS, PaaS, and SaaS that are
discussed further.

IaaS Cloud Architecture
 The IaaS is basically a service that
carries out computer infrastructure
on a basis that is outsourced so that
they can support the operations that
are carried out in the organization.
 The main focus of the IaaS is to
provide storage, hardware, network
or space for data centers, servers,
and also may include software
(Sadiku, Musa & Momoh, 2017).
 IaaS is also known by Hardware-as-a-
Service.
(Source: Hashem et al., 2015)

PaaS Cloud Architecture
 The PaaS is one of the most
important service among three
types of cloud computing
infrastructure.
 PaaS is a platform that uses
software, tools, and middleware for
coding purpose and then deploys
the applications involved in the
business (Manvi & Shyam, 2014).
 The application is basically created
with the help of PaaS and the
delivery of software is done on web
browser when needed.

SaaS Cloud Architecture
 The users using the SaaS service are
generally connected and the
applications that are involved in the
cloud are also utilized by them.
 The maintaining of the software and
the installing of the software is
involved in this service.
 The users runs the software from the
cloud clients over internet.

Advantages of Three
Approaches
Infrastructure-as-a-Service Cloud Architecture
 Flexibility
 Scalability
 Saves the cost
Platform-as-a-Service Cloud Architecture
 Cost effective than IaaS
 Less Virtual Management
 Supports Improved Version of Integration
Software-as-a-Service Cloud Architecture
 Very Cost Effective
 Stable

Current Infrastructure of
Regional Gardens
Presently the Regional Gardens uses
 2 x Active Directory domain controllers on Windows Server 2008
R2
 3 x SQL Server 2003 database servers on Windows Server 2003
 1 x Exchange 2007 email server on Windows Server 2008 R2
 4 x Windows Server 2003 File and Print servers
 2 x Red Hat Enterprise 5 Linux servers running Apache and
TomCat

Recommended Infrastructure
of Regional Gardens
The infrastructure that is recommended for
Regional Gardens is the IaaS Cloud
Infrastructure.
 The service of IaaS is very much flexible.
 The scalability is also provided by the service
(Rodriguez & Buyya, 2017).
 The cost of implementing the IaaS is very low .
