A. B. C. D.Answer - B.
Spot Instance and On-demand Instance are very similar in nature.
The main difference between these is a commitment.
In Spot Instance, there is no commitment.
As soon as the Bid price exceeds the Spot price, a user gets the Instance.
In an On-demand Instance, a user has to pay the On-demand rate specified by Amazon.
Once they have bought the Instance, they have to use it by paying that rate.
In Spot Instance, once the Spot price exceeds the Bid price, Amazon will shut the instance.
The benefit to the user is that they will not be charged for the partial hour in which the Instance was taken back from them.
Spot instances are not always cheaper than on-demand, they can and do sometimes fluctuate wildly, even to very high per hour amounts, higher than the on-demand price at times.
A Spot Instance is an unused EC2 instance that is available for less than the On-Demand price.
Because Spot Instances enable you to request unused EC2 instances at steep discounts, you can significantly lower your Amazon EC2 costs.
The hourly price for a Spot Instance is called a Spot price.
The Spot price of each instance type in each Availability Zone is set by Amazon EC2 and adjusted gradually based on the long-term supply of and demand for Spot Instances.
Your Spot Instance runs whenever capacity is available, and the maximum price per hour for your request exceeds the Spot price.
Options A and C are incorrect since Spot Instances can be taken back or interrupted and should not be used for critical workloads.
Option D is not a cost-effective solution.
You can use Spot Instances for non-critical workloads.

It allows running Docker containers on a cluster of EC2 instances. ECS can be used to deploy both critical and non-critical workloads, but the cost-effective setup will depend on the workload characteristics and business needs.
Option A: Use ECS orchestration and Spot Instances for processing critical data and On-Demand for non-critical data. This option uses Spot Instances for processing critical data and On-Demand Instances for non-critical data. Spot Instances are available at a lower price compared to On-Demand Instances but are subject to availability, and their prices may vary based on demand. This makes them a good fit for non-critical workloads, but not ideal for critical workloads. Critical workloads require more reliability and availability, which On-Demand Instances provide. Thus, this option is not a cost-effective setup for both critical and non-critical workloads.
Option B: Use ECS orchestration and On-Demand Instances for processing critical data and Spot Instances for non-critical data. This option uses On-Demand Instances for processing critical data and Spot Instances for non-critical data. On-Demand Instances provide higher reliability and availability, which are important for critical workloads. Spot Instances can be used for non-critical workloads since they are cheaper and can be interrupted without impacting the application. This option is a cost-effective setup for both critical and non-critical workloads.
Option C: Use ECS orchestration and Spot Instances for both the processing of critical data and non-critical data. This option uses Spot Instances for both critical and non-critical workloads. As mentioned earlier, Spot Instances are cheaper but can be interrupted, which is not ideal for critical workloads. This option is not a cost-effective setup for critical workloads since the risk of interruptions may lead to increased downtime and costs associated with restarting the application.
Option D: Use ECS orchestration and On-Demand Instances for both the processing of critical data and non-critical data. This option uses On-Demand Instances for both critical and non-critical workloads. On-Demand Instances provide higher reliability and availability, making them a better fit for critical workloads. However, On-Demand Instances are more expensive than Spot Instances. This option is a cost-effective setup for critical workloads, but not for non-critical workloads.
In conclusion, option B is the most cost-effective setup for managing both critical and non-critical workloads in ECS. It uses On-Demand Instances for critical workloads and Spot Instances for non-critical workloads, providing a balance between cost and reliability.
