Not an Advantage of Using the AWS Cloud

Answer: C.

Option A is incorrect.

Instead of heavily investing in Data Centers & Servers for hosting their applications, clients can consume resources from the AWS Cloud, e.g., Compute, Storage, and only pay for the resources they have consumed.

So Capital Expenditure (CAPEX) gets converted into Operational Expenditure (OPEX) while using a Cloud environment that results in Cost Efficiency for the client.

Option B is incorrect.

The AWS Cloud model helps eliminating to guess infrastructure capacity needs by offering a Scale on Demand model.

For example, during Christmas when there is a sudden increase in website traffic, additional resources (like EC2) can be created On-Demand (Scale- Up) to address the surge in traffic.

Similarly, when the festival period goes away, the additional resources that were created can be terminated (Scale - Down) so that the user does not need to pay for idle resources.

Option C is CORRECT.

AWS Cloud adopts a Shared Responsibility Model where Security & Compliance responsibility is shared between the Client & AWS.

This shared responsibility security model helps relieve the client of operational burden as AWS operates, manages & controls the components from the host Operating System and Virtualization layer down to the physical security of its facilities (Data Center's)

The client can effectively manage the Security of his applications & the infrastructure in which it resides.

AWS also helps customers to understand their robust controls in place to maintain security and compliance in the Cloud through their compliance certifications e.g., PCI DSS compliance.

Option D is incorrect.

AWS Cloud allows clients to focus on their Projects that differentiate their business rather than maintaining infrastructure.

AWS performs all the heavy lifting of maintaining facilities (Data Centers).

As an AWS Cloud Practitioner, when proposing AWS Cloud solution to a client as a value proposition, it is essential to highlight the advantages of using the AWS Cloud. These advantages include:

A. The AWS Cloud offers a pay-as-you-go model to trade Capital expense for Variable expense: AWS Cloud's pay-as-you-go model allows clients to pay only for the computing resources they use, without any upfront or long-term commitment. This way, clients can reduce their capital expenditure and convert it into operational expenditure, which can be beneficial for businesses that have fluctuating demand.

B. The AWS Cloud offers a Scale-on-demand model to eliminate wasted capacity: AWS Cloud's scalability model allows clients to scale their resources up or down depending on the demand. This eliminates the need for clients to provision resources that may go unused, reducing wastage and costs.

C. The AWS Cloud gives complete control of Security to its users so that they can replicate their Data Center Security model on the Cloud: AWS Cloud provides a secure infrastructure, and clients have complete control over their data security. Clients can replicate their data center security model on the cloud, which can give them peace of mind and ensure data security.

D. AWS Cloud frees the users from spending time & money for maintaining their Data Centers: AWS Cloud eliminates the need for clients to maintain physical data centers, which can be costly and time-consuming. AWS takes care of the infrastructure and the underlying maintenance, allowing clients to focus on their core business operations.

Therefore, the answer to the question "which of the following is not an advantage to use the AWS Cloud?" is C. The AWS Cloud gives complete control of Security to its users so that they can replicate their Data Center Security model on the Cloud. This is because this option is actually an advantage, and it is one of the reasons why clients choose to use the AWS Cloud.
