Despite this enormous investment, the current IT network infrastructure landscape doesn’t provide a robust means to manage the company IT needs in a more efficient and effective means. The problems faced by current landscape includes; less flexibility as the computing of the company is current tied to a location making it difficult for the employees and customers to interact with the business anywhere anytime. There is again the issues of greater administrative burden which includes doing administrative works that don’t really contribute to core business goals. Third, the current landscape reduces collaboration as the IT infrastructure has no central appeal since each region maintains its own pool of resources. The lack of central control of the IT network landscape makes it difficult to have more robust disaster recovery, especially if one or more regional data center suffers an information security attacks (Zeqiri, Aliu, Kostanica, & Prenaj, 2017). This challenges can be resolved by going to the cloud and virtualization of some hardware to reduce cost and make the administration of the company more efficient. Cloud computing integration shall also ensure there is scalability into the network to meet future market trends
Body
Task 1
Characteristics of Cloud computing
According to the NIST(National institute of standards and technology), cloud computing has the following five characteristics that are essential for bottlers company. They include
On-demand self-service
cloud computing architecture, network-aware services such as email, apps, network, and various server services can be seamlessly provided without the need to individually interact with each of the service providers (Yu, Cao, & Schniederjans, 2017).
On-demand nature of cloud computing is beneficial to bottlers company to only make payments for what they actually need. This is possible because this characteristic enables the company to define their specific needs and only subscribes to the service that caters to their defined needs. Moreover, this feature enables the company to be scalable in the future without having to worry about the initial costs of buying equipment. Last but not least, this feature gives a lot of convenience to the business since the business can tailor its robust IT network infrastructure to meet their particular business needs (Pise, 2019).
Broad network access
The cloud computing architecture makes the network have broader access using standards. This makes cloud computing environments to be accessible by remote and mobile users using mobile phones and laptops anywhere anytime.
This feature is of great importance to the company as it enables it to aggregate multiple regional offices thereby reducing the cost of running and maintaining regional data centers.
Resource pooling
Cloud computing network architecture ensures there is a great degree of resource pooling whereby critical computing resources are pooled together to be aimed at serving multiple clients and customers. This pooled resources can be combinations of physical and virtual resources which can be configured to be assigned dynamically and reassigned dynamically based on the customer needs. The provides some sense of location independence for the customer as they will have no control over which location the resource is pooled from. Resources such as storage, memory, processing and bandwidth can be pooled (Kathuria, Mann, Khuntia, Saldanha, & Kauffman, 2018).
Bottler company can greatly benefit from this nature of cloud computing as it reduces duplication of services across regional and national centers thereby reducing the cost of operating those regional offices
Measure services
This characteristic of cloud computing environments brings a more automated control of the IT network infrastructure resources and enhance optimized use by leveraging the capabilities of the cloud computing environments to have some metering capabilities with a degree of abstraction. This characteristic shall be of importance to bottlers company as the network infrastructure resources can be efficiently monitored, controlled and reported thereby enhancing transparency between the service provider and the customer of the utility company.
Task 2
Cloud computing delivery models
The delivery model can be defined as the type of model upon which the cloud computing environment is based. The delivery models are broadly categorized into the following categories
Infrastructure as a Service (IaaS)
Platform as a Service(PaaS)
Software as s Service(SaaS)
Infrastructure as a Service(IaaS)
This delivery model is perhaps the most basic level of service delivery on the cloud computing environment. IaaS can be defined as the delivery of computing technology and infrastructure on-demand as the services scales. IaaS model provides the mechanism to access the basic computing resources such as virtual machines, physical machines, virtual storage. In addition, the IaaS provides services such as
Virtual Local Area Networks(VLANs
Load balancing
Software bundles
IP addresses
Virtual machine disk storage
In this model, all the mentioned resources are made available to the end-user via the technology of server virtualization hence making the resources to be accessible by the cloud customer as though they own the resources (Goscinski, Broberg, & Buyya, 2011).
This service delivery model is will benefit the company in the following ways
The company shall be given the full control over the administration of the virtual machines
This model makes it more efficient and flexible to rent computing hardware
Offers portability and interoperability with existing legacy applications
The potential issues with this model include the following
Compatibility issues with the existing legacy systems security vulnerabilities
Data erasing practices
The sprawling of virtual machines
Platform as a Service(PaaS)
This cloud computing service delivery model focus on providing the runtime environment for application during development and deployment. In addition, it provides a range of deployment tool to use in application deployment
The PaaS provides the clients with the facilities needed to support the software life cycle for developing and deploying web-based application and services on the Internet.
The key benefits this model can bring to bottler company include;
Relatively lower overhead costs due to administration
The relatively lower total cost of ownership
Provides the latest stable version of the software in the environment
Provides more flexibility and scalability
Potential issues with this model include the following
There is a lack of portability among different PaaS clouds
Difficult to engineer security of the PaaS apps
Scheduling of processing is based on events
Software as Service (SaaS)
This cloud computing model allows the usage of a particular software application as a service to the users. This represents software that is deployed on some hosted services and then users access it via the Internet. The following application can be deployed and accessed as a service over the web
Billing and invoice system
Customer relationship management (CRM)
Human resource(HR) solutions
Help Desk Applications
This model can be of great benefit to the bottler’s company in the following ways
Provides more efficient usage of software licenses
Gives more control due to central management and data
Provides modest software tools
Have the multitenant capability
Despite its benefits, the SaaS model has the following issues
Browser risks
Depends on availability of network
Lack of portability among different SaaS clouds
Task 7
SCOM security and privacy issues
The System Centre Operation Manager(SCOM) provides a cross-platform data center for monitoring all the OS and the data centers. It does this by providing a single user interface that provides reports on the state, health, and performance of the computing systems. In addition, it provides alerts based on performance, availability, security, configuration,
Despite its beneficial use, the SCOM has some security and privacy issues as discussed below.
First, despite being good at reading logs, SCOM does not provide a foolproof management pack. It does not catch every intrusion into the network. This is because 100% of the time, it majorly depends on proper management of alerts. In terms of privacy, the SCOM agent-based monitoring tool violates the right to uncensored monitoring of user activities. The agent runs around the networking spying on user actions (Carstensen, Golden, & Morgenthal, 2012).
Task 8
To help address this issues in the private cloud, the bottler’s company should set up a good alert management process to ensure there is an end to end management of alerts to resolve them as soon as possible before they turn into real problems.

Operation Model
The above diagram shows the various operations and how different option available to integrate well with the proposed cloud platform migration
Task 10
Role of substitution strings
The substitution strings are widely used in defining a template for cross-platform notification messages. The Azure platform has a set of notification hubs that uses the substitution strings to transform a platform-dependent notification message into a more cross-platform template that can be sued to send platform-independent notification messages (Al-Zoubi & Al-Masaiid, 2019).
In this approach, the actual message gets substituted with the expressions templates. The templates get filled with the message based on a JSON file that can hold multiple templates. This approach of sending notification using the substitution strings in the message body of the notification allows more personalized experience in using apps on the Azure platform.
Conclusion
In conclusion, this report provides more insights into the benefits of cloud computing by explaining what each delivery model can positively impact company operations. The report further provides some security and privacy issues that are associated with the cloud platform. For each concern, a more elaborate method to avert the risk of the issues is addressed. And finally, a project plan detailing a migration plan to Microsoft azure is discussed
Summary
This report highly recommends bottlers company to go the hybrid way to reap the benefits that accrue to the cloud environment while maintaining a high level of control and personalization of services offered by having a private cloud.
The report recommends none sensitive services such as web and software that can be deployed on the web to be migrated to the public to cut cost and provide wide coverage
Server virtualization is highly recommended for the bottler company to efficiently utilize the available physical and virtual resources at the companies disposal
