a) The cloud architecture according to the service can be categorized into following
categories-
 Infrastructure-as-service: It provides the
fundamental resources like virtual machines, virtual
storage. It also offers- Software bundles, load
balancers, virtual local area network (Tarasuk-levin
et al.,2017). All these things are available through
the virtualization of the server`
 Platform -as-service: This models provides the run
time environment for the applications. Apart from
that, this model also provides the development tools
for the application. App Engine of Google is an
example of this kind of cloud model.
 Software-as-service: This type of cloud model
provides the software applications to the end users.
The cloud architecture according to the deployment model can be categorized into three
types-
 Public cloud: The public cloud system allows to
access the services to the people provided by the
cloud. Various IT giants like Google, Aamzon
offers this kind of public cloud services via internet.
 Private cloud: This kind of cloud deployment model
allows the use of the cloud architecture within the
organization.
 Hybrid cloud: Hybrid cloud allows the merging of
the public and private cloud (Kousalya,
Balakrishnan & Raj, 2017). In this model, the non-
critical data and information are stored in the public
cloud, while the important and sensitive data are
managed by the private cloud.
In case of the Regional Gardens, meeting the requirement of the board , the
implementation of the hybrid cloud can be done (Watt, 2016). The confidential data of the
company can be managed by the private cloud and the non critical data can be stored to the
public cloud. This will help the Regional Gardens to save the cost of the infrastructure along
with providing the better service.

b) Advantages of using hybrid cloud:
 Hybrid cloud features both public cloud scalability and private cloud
scalability.
 The deployment of the hybrid cloud offers the flexibility of the service.
 Security is maintained for the public cloud is done by the third party cloud
provider (Chang et al.,2015). However, in case of private cloud , the
security can be maintained by the organization itself or the third party
cloud provider.
Disadvantages of hybrid cloud:
 The network architecture become complex as both private and public
cloud is involved in the system
 The hybrid model of the cloud is dependent on the internal IT
infrastructure. So, the redundancy across the data centers should be
necessary.
Advantages of the public cloud:
 Public cloud enables the sharing of the large amount of resources from
the different locations among the users. It makes the solution provided by
the cloud inexpensive.
 The public cloud is flexible to use and it can be merged with the private
cloud.
 The resources from the public cloud can be accessed from any location.
Disadvantages of the public cloud:
 Low security
 Less chances for customization.
Advantages of the private cloud:
 It provides cost and energy efficient solutions to the organization.
 Private cloud provides security of higher degree.
 It provides more control over resources.
Disadvantages of the private cloud:
 This model has limited scalability.
 This model is expensive compared to the other cloud models.
 The operation is limited to the certain area.

Risks Description Possible solutions

5MIGRATION TO THE CLOUD
Design of IT architecture A hybrid cloud is a complex
architecture. It is the
combination of public cloud
and private cloud (Qiu et
al., 2015). To manage the
hybrid cloud a group
experts are required.
The management can hire a
group of experts who have
vast knowledge about the
cloud computing and
managing the hybrid cloud.
Security risks The main risk associated
with the hybrid cloud
approach is the security
risks. Managing sensitive
data in hybrid cloud
approach is critical
(Baldwin,2017). The
sensitive data cannot go to
the public cloud. For this
reason, there is a need to
identify the sensitive data.
The employees of the
organization should be
trained to identify the
difference between the
confidential data and the
non-critical data. They
should be made aware about
the importance of protecting
the confidential data.
Finding the efficient
strategy is difficult
The guidance about
managing the cloud is very
little. It is the responsibility
of the company to create a
effective cloud strategy. In
this case each cloud
provider has the different
approach towards the
implementation of the
cloud. The organizations
can find it difficult to
choose the right cloud
provider.
The selection of the third
party cloud provider can be
based on the requirements
of the company. The
organization should conduct
a meeting with the
stakeholders in order to
know the requirements
clearly.
Limited capacity in terms of
computing and storage of
the data while using the
micro services
The micro services needs to
deliver the high end
mechanism in the system.
Different tools are needed
to be deployed in order to
manage the micro services
in the organizational system
No standardization is
present for the deployment
of the micro services
The organizations are
embracing the use of micro
services along with the
implementation of the
hybrid cloud computing.
However, there is no certain
guideline for the
implementation and
managing of the micro
services.
The organization can
consults with experts about
the pros and cons of
different micro services
(Park et al.,2017). The
implementation and
managing strategy can be
initiated after the discussion
with the IT experts.

3. Information security steps for the hybrid cloud:
 Hybrid cloud is the combination of the public cloud and private cloud. In
this case, choosing the right public cloud provider is essential as the
security of the public cloud is maintained by the third party vendor.
 Centralization of the governance and control of the implementation of the
cloud is important (Curzi & Ryan,2016). This will ensure the maintenance
of the certain strategies along with applying the regulations and policies in
for the deployment of the cloud. The organization needs a line-of –
business manager in order to select the right cloud provider.
 The solutions provided by the hybrid cloud should provide data protection
(Bagepalli et al.,2017). The infrastructure those are being used in the
hybrid cloud technology should incorporate with the latest built-in model.
4. The factors should be included in the BCP as the result of adoption of the cloud:
Resiliency and related challenges:
It is important for the organization to improve the resiliency and continuity in the
business. Resiliency can provide the Regional Gardens more agile and flexible solutions
by helping to add or remove the resource when it is needed. Certain factors are included
in this trend:
 The increased use of virtualization.
 The complex structure of the cloud is distributed and the data recovery is a
complicated process in this system (Vasetsky et al.,2018). The
maintenance of the backup and recovery system at home will help to
reduce the cost of the hardware maintenance.
 The Regional Garden can increase it s business in future. In this case, poor
performance and unavailability of the services can give the company a
poor performance.
Disaster recovery has certain significance in the decision of adopting the
cloud computing. The disaster recovery strategy is provided by the cloud
provider. In this case, the selection of the right cloud provider is needed.
5. Factors needed to be considered by the regional gardens:
Checklist Description
Governance of the
billing and the
account
The detailed description of the billing and accounts department
should be checked before the implementation of the cloud
computing the organization.
Management of the
security and the
access
The security of the operating system, network, AWS and API is
needed to be evaluated.
Management of the
assets
The organizations should identify the resources regarding AWS.
Resilience The organization should be aware if the implemented AWS is

meeting the requirements of the clients and the organizations.
Backup The AWS system should meet the disaster recovery strategies.
Monitoring The Regional Gardens should have the appropriate tools for
management of the integrated AWS resource.
Configuration
management
The implemented AWS should have change and management
configuration strategy.
