Project overview

As an IT analyst for BallotOnline, a company providing voting solutions to a global client base, you are working to convince the organization to move its infrastructure to a public cloud. With the growth the company is experiencing and the internal data centers maxed out, you want to get the executives on board with moving to a public cloud rather than trying to expand the current infrastructure.

This project will be completed in a series of steps, in which you will explore cloud technologies and cloud architecture and how they can be used in the organization.

Your presentation with audio narration will educate the executives on cloud computing and its benefits (and drawbacks) to the company. To complete your analysis, you will need to cover the following:

• description      of cloud computing
• basic      capabilities of the cloud
• advantages      and disadvantages of cloud computing
• analysis      of economic implications
• IT      business needs
• SWOT      analysis

There are six steps in this project. In your final narrated PowerPoint presentation, you will be assessed on your ability to convey your understanding of cloud computing and how it can be used to benefit your organization, explaining the advantages and disadvantages of cloud computing and providing a detailed business analysis covering financial considerations, business requirements, and an analysis of threats and opportunities.

Step 1: Describe Cloud Computing

Your supervisor, Sophia, BallotOnline’s director of information technology, has tasked you with creating a presentation that will convince the executives that using cloud-based computing to accommodate BallotOnline’s future growth rather than trying to expand the current infrastructure will help the company do business faster and at lower cost while conserving IT resources.

Step 2: Research Advantages and Disadvantages of Cloud Computing

Now that you have defined important terms and summarized the basic capabilities of the cloud, it is time to explore the advantages and disadvantages of cloud computing.

Currently, BallotOnline is running at full capacity and needs to expand its IT infrastructure to accommodate its growing needs. Instead of expanding current on-premise IT infrastructure by building or acquiring a new data center, Sophia has suggested that the cloud may be more efficient and cost-effective than adding more traditional physical data center space.

This information that you research will be useful in your final presentation in the last step.

When you have completed the research, move to the next step, where you will consider the budgetary aspects of a move to the cloud and the implications for the organization.

Step 3: Analyze Economic Implications

Now that you have weighed the benefits and drawbacks of cloud computing, it’s time to take a close look at the economic implications of a move to the cloud. All organizations (for-profit, nonprofit, or government) have finite budgets. Management must allocate these financial assets appropriately so that the leaders can make sound business decisions and meet the objectives of the organization.

Information technology (IT) is a key strategic function to help support the objectives of an organization. Businesses first used information systems to replace paper-based methods of helping management perform these functions, and that use continues today. Managers must be able to understand different IT models to make the best financial investment decisions for the organization.

The financial requirements for the cloud computing model are different than the financial requirements for an on-premise model. Cloud computing shifts budgets to a pure operating expense model, whereas the traditional on-premise computing model requires both capital and operating expense allocations.

Several free calculators to help estimate the cost of cloud services exist on the web, including the AWS Total Cost of Ownership (TCO) Calculator and Azure TCO Calculator. Alternatively, you may find other calculators to estimate your cloud cost. Most cloud providers have their own cloud cost estimator tools. If the calculator that you selected does not show on-premise data, then you can recalculate using one of the other calculators that do provide this data.

For your economic analysis, enter the information from BallotOnline’s IT Budget and Infrastructure Summary into your chosen calculator to estimate TCO for the current physical IT infrastructure configuration. Then estimate TCO for a comparable configuration in the cloud to estimate the potential cost savings.

Write the summary of the economic implications, showing the savings and how you arrived at them, and upload it to the dropbox below.

Step 4: Define the IT Business Requirements

After considering the economic aspects of the cloud, the next logical step is to narrow the particular requirements of cloud computing for the organization. It is important that your presentation works toward building a business case for cloud computing.

Your presentation must address BallotOnline’s business requirements and critical IT requirements related to data storage. Make sure you classify the requirements into functional (behavior) and nonfunctional, as per the requirements definition link.

Step 5: Prepare a SWOT Analysis

In this step, you will apply the information gathered in the business analysis to assess the benefits and possible drawbacks of adopting cloud infrastructure for BallotOnline.

Take Note

What Is a SWOT Analysis?

Your supervisor, Sophia, recommends that you include a SWOT analysis in your presentation, since the BallotOnline company executives will want you to go over both the advantages and disadvantages of cloud adoption and any important internal and external factors that may influence the success of the project.

Prepare a Presentation on Benefits and Possible Drawbacks of Adopting Cloud Infrastructure

In this step, you will prepare your presentation for the BallotOnline executives. This presentation should present them with a compelling business case and cover the benefits and possible drawbacks of adopting cloud infrastructure, data on cloud economics, and a demo of some basic cloud capabilities.

Need 3 answers for each question.  1 APA reference MUST. APA 7th edition

Question 1:

Excel is probably the most popular spreadsheet software for PCs. Why? What can we do with this package that makes it so attractive for modeling efforts?

Question 2:

What are the common business problems addressed by Big Data analytics?  In the era of Big Data, are we about to witness the end of data warehousing? Yes/No Why?

The city council in the town of Durburn has decided to improve road sign placement, especially for the numerous dead ends that are currently unmarked in various parts of the city. They have given you a road map, and you must determine where to put up signs to mark all the dead ends. They want you to use as few signs as possible.

The road map is a collection of locations connected by two-way streets.

The following rule describes how to obtain a complete placement of dead-end signs:

Consider a street S connecting a location x with another location. The x-entrance of S gets a dead-end sign if, after entering S from x, it is not possible to come back to x without making a U-turn. A U-turn is a 180- degree turn immediately reversing the direction.

To save costs, you have decided that you won’t install redundant dead-end signs, as specified by the following rule:

Consider a street S with a dead-end sign at its x-entrance and another street T with a dead-end sign at its y-entrance. If, after entering S from x, it is possible to go to y and enter T without making a U-turn, the dead-end sign at the y-entrance of T is redundant. INPUT

The first line of input contains two integers n and m, where n (1 ≤ n ≤ 5*105) is the number of locations and m (0 ≤ m ≤5 * 105) is the number of streets. Each of the following m lines contains two integers v and w (1 ≤ v < w ≤ n) indicating that there is a two-way street connecting locations v and w. All location pairs in the input are distinct.

OUTPUT

On the first line, output k, the number of dead-end signs installed. On each of the next k lines, output two integers v and w marking that a dead-end sign should be installed at the v-entrance of a street connecting locations v and

w. The lines describing dead-end signs must be sorted in ascending order of v-locations, breaking ties in ascending order of w-locations
