:Implement a Cloud Computing Solution Using Common Cloud Platforms

SCENARIO: Your organization has agreed with your findings several weeks ago, and agrees that it is time to implement a cloud solution. It has asked that data be stored offsite for backup purposes, preferably through a commonly used and reliable vendor. It also requests that instead of data being stored locally, that there is a central storage location for all users. It has asked that all users now use a common virtual image based on the following departments: FINANCE, MANAGEMENT, IT, and HUMAN RESOURCES.

You are to provide a 3-4 page document illustrating your plan to implement a solution that will not only replace the current network structure, but explain how this will improve the organization’s performance and security. Also, be sure to include any risks that may also occur because of this change, and recommendations on how to accept, transfer, or mitigate this risk. Include a general sketch of how the network topology should look once you’ve finished the transition.

Explanation / Answer

Answer- Cloud Computing is a computing model that enables sharing of resources on-demand with cost effectiveness and location independent. In Cloud systems the customers need not to buy any resources in their own instead they can use the resources from the cloud and they can pay for the resource as per the usage. Cloud computing is a technology that offers many advantages, in that the main drivers of cloud computing is the following Cost Saving Improved Flexibility Better Scalability

Cloud computing services can be offered in three basic ways: Software as a Service, Platform as a Service, and Infrastructure as a Service. Some CSPs (cloud service providers) have multiple offerings, such as Microsoft Azure and Amazon Web Services, which can provide both infrastructure and platform services.

Software as a Service (SaaS)

Platform as a Service (PaaS)

Infrastructure as a Service (IaaS)

Implementing a cloud computing solution will improve the organization’s performance and security in following ways:

1. Fresh Software

With SaaS, the latest versions of the applications needed to run the business are made available to all customers as soon as they’re released. Immediate upgrades put new features and functionality into workers’ hands to make them more productive. What’s more, software enhancements are typically released quite frequently. This is in contrast to home grown or purchased software that might have major new releases only once a year or so and take significant time to roll out.

2. Do more with less

With cloud computing, companies can reduce the size of their own data centers — or eliminate their data center footprint altogether. The reduction of the numbers of servers, the software cost, and the number of staff can significantly reduce IT costs without impacting an organization’s IT capabilities.

3. Flexible costs

The costs of cloud computing are much more flexible than traditional methods. Companies only need to commission – and thus only pay for – server and infrastructure capacity as and when it is needed. More capacity can be provisioned for peak times and then de-provisioned when no longer needed. Traditional computing requires buying capacity sufficient for peak times and allowing it to sit idle the rest of the time.

4. Always-on availability

Most cloud providers are extremely reliable in providing their services, with many maintaining 99.99% uptime. The connection is always on and as long as workers have an Internet connection, they can get to the applications they need from practically anywhere. Some applications even work off-line.

5. Improved mobility

Data and applications are available to employees no matter where they are in the world. Workers can take their work anywhere via smart phones and tablets—roaming through a retail store to check customers out, visiting customers in their homes or offices, working in the field or at a plant, etc.

6. Improved collaboration

Cloud applications improve collaboration by allowing dispersed groups of people to meet virtually and easily share information in real time and via shared storage. This capability can reduce time-to-market and improve product development and customer service.

7. Cloud computing is more cost effective

Because companies don’t have to purchase equipment and build out and operate a data center, they don’t have to spend significant money on hardware, facilities, utilities and other aspects of operations. With traditional computing, a company can spend millions before it gets any value from its investment in the data center.

8. Expenses can be quickly reduced

During times of recession or business cut-backs (like the energy industry is currently experiencing), cloud computing offers a flexible cost structure, thereby limiting exposure.

9. Flexible capacity

Cloud is the flexible facility that can be turned up, down or off depending upon circumstances. For example, a sales promotion might be wildly popular, and capacity can be added quickly to avoid crashing servers and losing sales. When the sale is over, capacity can shrink to reduce costs.

10. Facilitate M&A activity

Cloud computing accommodates faster changes so that two companies can become one much faster and more efficiently. Traditional computing might require years of migrating applications and decommissioning data centers before two companies are running on the same IT stack.

11. Less environmental impact

With fewer data centers worldwide and more efficient operations, we are collectively having less of an impact on the environment. Companies who use shared resources improve their ‘green’ credentials.
