AI Summary
This report delves into the complexities of cloud migration, specifically focusing on the implementation of a hybrid cloud architecture for Regional Gardens. It begins by categorizing cloud architectures based on service and deployment models, including Platform-as-a-Service, Infrastructure-as-a-Service, Software-as-a-Service, and public, private, and hybrid cloud deployments. The report emphasizes the advantages and disadvantages of hybrid cloud, including its flexibility and security benefits, while also addressing network complexity and redundancy concerns. A detailed risk assessment is provided, identifying potential challenges in architecture design, security, and strategy development, along with proposed solutions. The report outlines key steps for ensuring information security in a hybrid cloud environment and highlights important factors for business continuity planning (BCP). Furthermore, it includes a checklist for Regional Gardens, covering billing, security management, asset management, resilience, backup, and monitoring. Finally, the report concludes with a step-by-step guide for migrating eMail to the AWS cloud, covering assessment, proof of concept, data migration, application migration, cloud leverage, and optimization phases, to provide a comprehensive overview of the cloud migration process.

1THE MIGRATION TO CLOUD
1.
a) The types of cloud architecture:
The cloud architecture can be classified depending on the service model and the
deployment model.
The cloud architecture can to categorized in three different kinds according to the
service:
Platform-as-service: Platform-as-service provides the run time application
to the users. The users can run and develop the application using this
service (Thakkar et al.,2016). One of the major platform-as-service is the
IDE of some software (Tarasuk-levin et al.,2017). Google provides App
Engine, which is an example of the platform-as-service.
Infrastructure –as-service: Infrastructure-as-service provides the primary
resource for the running of the processes like the virtual machine , virtual
local area network and the software bundles (Chang et al.,2015). This
architecture enables the virtualization of the server.
Software-as-service: This platform ensures the users can use the software
through the internet.
The cloud architecture can be categorized into three types based on the method
of deployment:
Public cloud: The users can access the services from the public cloud. The access right is
open for all the users in case of public cloud (Chang et al.,2017). Major IT companies offer the

public cloud service to the users. One of the most significant IT cloud is offered by Google. The
security of the public cloud is maintained by the third party cloud providers.
Private cloud: The private cloud allows to store the data which can be accessed by the
organization. The security of the private cloud can be maintained by the organization or the
cloud service providing vendor (Beaty et al.,2015). However, the private cloud is more secured
and equally expensive for the deployment.
Hybrid cloud: Hybrid cloud enables the merging of the public cloud and the private
cloud. It is the cost effective solution for the organizations which provides the efficiency. In this
model the ordinary data are stored in the public cloud, whereas the critical and confidential
information are stored in the private cloud (Menzel et al.,2015). The security of the public cloud
is managed by the cloud provider and the private cloud is managed by the organization.
The implementation of the hybrid cloud can be done in case of Regional Garden. The
organization can migrate the partial data to the public cloud and rest of the data can be kept in
the private cloud (Yangui et al.,2016). This will help to give a cost effective solution to the
organization by reducing the cost of maintaining the infrastructure. The security of the private
cloud can be managed by the Regional Gardens itself.
b) Advantages of the hybrid cloud:
Hybrid cloud allows the use of both public cloud and the private cloud.
It offers the flexibility in the solution.
Security of the cloud architecture is handled in an effective way.
Disadvantages of the hybrid cloud:

The network allows the deployment of both private cloud an d the public cloud. This
makes the network more complex.
The hybrid model is dependent on the redundancy of the network.
Advantages of the public cloud:
It allows the sharing of the large amount of resources among the users. The solutions
provided by the public cloud is inexpensive.
The public cloud can be accessed from any part of the location.
The use of public cloud is flexible. It enables the merging with the private cloud to create
the hybrid cloud architecture.
Disadvantages of the public cloud:
The security is the main concern in the public cloud architecture. The security is
maintained by the cloud provider.
The options for the customization in the public cloud is very much less in the public
cloud architecture.
Advantages of the private cloud:
The security is the major advantage of the private cloud. The data can only be accessed
by the organization.
It provides more control over the resources used by the organizations.
Disadvantages of the private cloud:
The implementation of the private cloud is expensive.
The scalability of the private cloud is limited.

Risks Descriptions of risks Solutions
Architecture design The architecture and
management of the
architecture in the hybrid
cloud is a complex thing.
The company can indulge a
group of experts to manage
the architecture of the
hybrid cloud.
Risks regarding security The risk with the hybrid is
the security risk. The data
management in the hybrid
cloud is complex (Ahmad et
al.,2015). The identification
of the sensitive data is
needed as, it cannot
included in the public cloud.
The workers in the
company are needed to be
trained so that they can
identify the sensitive data.
Developing the right
strategy is difficult
There is no regulations for
implementation of the cloud
(Breiter et al.,2015). So, it is
difficult to manage the
cloud with right strategy.
Before giving the
permission of maintaining
the security to the third
party cloud provider, the
organization should conduct
a meeting with the
stakeholders.
No existing standard for the
micro service deployment.

consult with the experts
about different features of
different micro services.
3. Steps for information security in hybrid cloud:
The hybrid cloud is the combination of public and private cloud. In this
case the selection of the public cloud needs to be done carefully.
The implementation and monitoring of the cloud needs to be centralized.
The deployment of the hybrid cloud should ensure the protection of the
data. The equipments used in the implementation should be of latest
technology.
4. The important factors for BCP:
Challenges related to resiliency:
The resiliency and continuity in the business process is important as it will help
the Regional Gardens to expand the business and will help to get the required
resources. Some of the important factors regarding this attribute are-
The use of virtualization will be increased.
One of the major challenge is the complex data recovery system and
backup and maintenance system.

There is a chance of poor performance and unavailability of resources
which can become a constraint for the growth of the business of the
organization.
5. Concerns for the Regional Gardens:
Checklist Description
Billing and accounts Before the implementation of the system, the evaluation of the
accounts details are needed to be done.
Security management. The security of the AWS and API along with the operating system is
needed to be evaluated.
Managing the assets The resources regarding the AWS is needed to be identified by the
organizations.
Resilience During the implementation of the AWS the organization should be
aware of the requirements of the client.
Backup The implemented AWS system is needed to be supported by the
disaster recovery strategy.
Controlling and
monitoring
The implemented AWS by the Regional Gardens is needed to manage
the integrated AWS resource.
Managing the
configuration
The AWS system should be monitored during the change in the
system.
