Step 4: Propose Cloud Architecture for BallotOnline Deployment
Now that you have looked into cloud architectures, in this step, you will propose the cloud deployment architecture for BallotOnline, applying the knowledge of typical architectural elements of cloud deployment from the project’s initial step. You will also consider trends and migration issues from a previous step. Your recommendation should consider the company’s business requirements. Project 3: Cloud Provider Evaluation
Recall that the company has an existing web application that it wants to move to the cloud, and also that the company wants to expand its business to other parts of the world. In earlier projects, you learned about and analyzed the IT business requirements for BallotOnline. Among them were demands for application and data security, data encryption, and separation for deployments overseas. Also, the application should handle load peaks during election times in different regions.
Specific technical requirements state that BallotOnline is a web application, written using the popular open-source LAMP (Linux, Apache, MySQL, PHP) software suite and the PHP application.

Step 5: Research AWS
You’ve described your proposed architecture and included a diagram to provide leadership a way to envision the system. Now, it’s time to look closely at the leading cloud providers to see if their services will fit BallotOnline’s needs.
Each cloud provider provides a unique profile of services, so it is good practice to compare cloud vendors and evaluate their reliability, performance, ease of use, cost, security and compliance measures. As more providers enter the marketplace, many will specialize on specific needs and use cases, making this evaluation even more critical. Project 3: Cloud Provider Evaluation
In this step, you will explore AWS and assess the feasibility of this platform for deploying the architecture proposed in the previous step. You should also consider issues related to AWS Pricing.
Based on your research, determine to what degree AWS supports the elements of the BallotOnline business and technical requirements.
Share your thoughts with your colleagues in the Discussion: Amazon Web Services Feasibility forum. In the following step, you will do the same for Microsoft Azure.

Step 6: Research Microsoft Azure
Now that you have had a chance to research AWS, it’s time to explore Microsoft Azure, another cloud provider that could be used to deploy the proposed architecture. You should also consider issues related to Microsoft Azure pricing.
Based on your research, determine to what degree Microsoft Azure supports the elements of the BallotOnline business and technical requirements. Share your thoughts with your colleagues in the Discussion: Microsoft Azure Feasibility forum.

Step 1: Research Networking and Auxiliary Services in the Cloud
The executives at BallotOnline have been impressed with your research on cloud computing thus far. While there are a variety of cloud providers, BallotOnline is considering using Amazon Web Services (AWS) and Microsoft Azure, two of the top providers in the market. BallotOnline’s executives want you to help determine which would be the best provider for the organization. Project 3: Cloud Provider Evaluation
You will start with learning about internet networking basics and cloud networking. You will also research many cloud services that cloud providers make available to their customers to help them take full advantage of cloud service and deployment models.

Step 2: Research Cloud Trends, Best Practices, and Migration Issues
The cloud computing revolution is redefining ways that companies of all sizes use information technology. The cloud landscape shifts rapidly, and current trends reflect this rapid pace of change. You likely got an idea about this in the last step when you conducted research on cloud architecture. Now, continue gathering information for your final report by assessing:
- issues outside the company, such as emerging issues in the industry, regulatory changes, and general trends in cloud computing to gain an understanding of how these issues may influence BallotOnline’s decisions;
- best practices for cloud implementation and assess whether BallotOnline can benefit from these;
- cloud migration strategies for the application and data, since BallotOnline is moving an existing web application to the cloud, making sure that the application is configured properly for the system architecture of your cloud deployment; and
- IT change management techniques that could help BallotOnline make this transition.
In the Discussion: Cloud Trends and Migration Issues forum, post your findings and discuss them with your colleagues.

Step 3: Research Typical Architectures of Cloud Deployments
In the previous step, you considered best practices and trends in the cloud industry. Next, you will have to look at the kinds of architectures needed for cloud. Project 3: Cloud Provider Evaluation
Because most elements of cloud deployments are implemented in a virtualized environment controlled by software, the degree of freedom in defining your deployment of cloud reference models is unprecedented. You can define the number of virtual servers required and the configuration, and even change them dynamically as needed. You can also define your virtual local area networks (LANs) and subnets, and place servers in them to implement network security requirements.
The basic cloud deployment components are cloud consumer, cloud provider, and cloud carrier, with cloud brokers and auditor as possible additions.

Typical cloud architectures of cloud deployments vary from single server (suitable for proof-of-concept engagements) and multiserver architectures with various servers carrying different software components and occupying different security zones, to geographically dispersed deployments to achieve high availability, resilience, and speed of delivery. There are several issues to consider when selecting a server architecture, including cost, scalability, performance, and use of management.
For this step, research the typical architectures of cloud deployments and begin to consider what might be a good fit for BallotOnline. Discuss your findings and thoughts with your colleagues in the Discussion: Cloud Architectures forum. Project 3: Cloud Provider Evaluation
