Moving to Cloud Infrastructure: Concepts, IAAS, PAAS, SAAS, and Benefits for Regional Garden Ltd.

This presentation covers the main concepts of cloud computing, including IAAS, PAAS, and SAAS. It also discusses the benefits of cloud computing for Regional Garden Ltd., such as cost-effectiveness, full control over the software platform, and minimal management. Additionally, suggestions for frontend and controller configurations are provided.

Moving to Cloud Infrastructure

Main concepts of Cloud Computing
A cloud provides a diverse IT environment that is deliberate for the purpose of remotely provisioning scalable and
measured IT resources. Cloud provides a unlimited storage facilities with scalable services.

Infrastructure As A Service(IAAS)
Infrastructure as a service is recommended for highly automated and scalable resources. It also has the ability of
metered, available on demand service and self -provision. IAAS offers cloud services via Dashboard or API that
allows straight access over storage and servers with a higher level of scalability( Dinh, Niyato & Wang, 2013).

Platform As A Service
Cloud provider will gain full access to customer’s data unless cryptography is used Platform as a Service functionality
is slightly lower than SAAS and offers a platform to develop and deploy software. It also provides clients accessibility
over the server software and underlying server hardware that helps them to focus on more in company’s side of
scalability

RAM, 250GB RAID-1 array);
2 x Red Hat Enterprise 5 Linux servers running Apache and TomCat (2
x Xeon 2.8GHZ, 16GB RAM, 140GB HDD).

Required Infrastructure
• While many of the early movers based their solutions on open source
solutions and commodity like x86 systems running open source Xen
and distributions like CentOS, service providers and enterprises have
necessities around both proprietary systems and commodity when
constructing out their clouds(li et al., 2013).

Problems of Traditional IT Infrastructure
• Implementing quality EA requires a deep and broad
understanding of EA and its role in the organization.
• Many EAs are too complex and rigid. This prevents
them from accommodating changes necessitated by
changes in business situations.
• EA is a separate practice and requires a practice-
based management. Yet, organizations put people
in charge of EA who are people-focused and not
practice-focused.
Cloud Solution
• Software applications, which can include
productivity suites such as SQL Server, Office,
Exchange email, SharePoint VMware ESX Server,
finance programs such QuickBooks Server or an
organization search program.
• Service areas, which can include functions such
as monitoring, authentication mechanisms and
task schedulers. For example, you can certainly
consider replacing complex in-house services such
as Windows Azure Active Directory and Active
Directory with online services .

HOW COULD CLOUD BE BENEFICIAL TO REGIONAL
GARDEN LTD.
• It is more cost effective comparison to in-housing as no leasing of
resources is required only software platform is essential.
• It provides full control over the software platform.
• Integration of new systems is not an issue when using a cloud
collaboration platform.
• Minimal management is necessary to utilize VM as it is the
responsibility of service provider(Xiao.
• Song & Chen, 2013).
• Clients can fully control and run its own virtual infrastructure without
the maintenance and invest in external hardware.
