Regional Gardens Cloud Computing Infrastructure

The assignment details the current infrastructure used by Regional Gardens, which includes 2 x Active Directory domain controllers, 3 x SQL Server database servers, 1 x Exchange email server, and 4 x Windows File and Print servers. It also recommends an IaaS cloud infrastructure for Regional Gardens, highlighting its flexibility and scalability. The recommended infrastructure aims to reduce costs while maintaining a stable and secure environment.

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 .
