Not all Economic benefits to clients using AWS cloud services

Answers: A.

Option A is CORRECT.

CPU bound software licenses will require a Dedicated Host tenancy model rather than a Shared tenancy model for the EC2 instances hosting the MySQL Database software.

Dedicated hosts are the most expensive tenancy model when it comes to pricing.

For example, an m4 large On Demand dedicated host is 24 times more expensive than an On-demand shared host.

A dedicated host tenancy may be used under exceptional circumstances of spiky traffic, while purchasing Hardware On-Premise may not be the best option.

Then the client can take advantage of Cloud Elasticity.

Option B is incorrect.

Batch processing jobs rely more on accuracy rather than on speed which forms a good use case for using Spot Instances, providing economies of compute where intermittent disconnections may not be a real problem.

Option C is incorrect.

AWS Reserved Instances have discounts on the EC2 usage.

This method can provide an economic benefits.

Option D is incorrect.

S3 Intelligent Tiering is a smart solution for managing the lifecycle of S3 objects resulting in economies of cost.

With intelligent tiring, there are no retrieval fees nor there are any fees for moving objects between tiers unlike using S3 Lifecycle policies which incurs data transfer charges.

S3 Lifecycle policies are also often challenging to define due to the unpredictable nature of application adoption and usage.

Even in scenarios where access frequency is known, it may so happen that customers may not use proper storage class adjustments resulting in non-optimized budgets.

Option E is incorrect.

An Active-Passive failover will always be economical to a client using the strategy for Disaster Recovery scenarios since he will not be investing in an entire redundant site with all resources running simultaneously.

He will have the flexibility to select his strategy depending on his Recovery Time objectives.

This will help him to save on costs.

Out of the given options, the answer is A.

Explanation:

AWS provides numerous benefits to its clients, including economic benefits. Economic benefits refer to cost savings that clients can experience by using AWS cloud services instead of building and maintaining their own infrastructure. Let's analyze each option to see which one may not be an economic benefit for the client.

A. The client is running a dedicated MySQL Database Server on AWS with his own CPU bound license (BOYL).

This option may not be an economic benefit for the client because the client is using his own CPU bound license (BOYL). This means that the client is responsible for paying for the license, which may not be cost-effective compared to using AWS licenses.

B. The client is running Spot Instances for batch data processing workloads.

This option is an economic benefit for the client because Spot Instances are significantly cheaper than On-Demand Instances. Spot Instances allow clients to bid on unused EC2 capacity and pay the current Spot price. Clients can save up to 90% on their EC2 costs by using Spot Instances.

C. The client is running applications with a relatively predictable and consistent resource demand using AWS Reserved Instances.

This option is an economic benefit for the client because Reserved Instances allow clients to commit to using specific instance types in specific Availability Zones for a one- or three-year term. This commitment provides clients with significant cost savings compared to On-Demand Instances.

D. The client is using S3 Intelligent Tiering storage class while uploading objects.

This option is an economic benefit for the client because S3 Intelligent Tiering is designed to optimize costs by automatically moving data between two access tiers based on changing access patterns. This feature helps clients save costs by reducing the need to manually move data between different storage classes.

E. The client is using an Active-Passive failover routing strategy of his On-Premise Data Center to AWS cloud.

This option is an economic benefit for the client because it allows the client to use AWS resources as a disaster recovery site, which can be significantly cheaper than maintaining a separate disaster recovery site on-premise. Additionally, the client can use AWS resources only when needed, which reduces the overall costs of maintaining a disaster recovery site.

In summary, out of the given options, option A may not be an economic benefit for the client. The client is using his own CPU bound license (BOYL), which may not be cost-effective compared to using AWS licenses.
