A company runs a stateful production application on Amazon EC2 instances The application requires at least two EC2 instances to always be running.

A solutions architect needs to design a highly available and fault-tolerant architecture for the application. The solutions architect creates an Auto Scaling group of EC2 instances.

Which set of additional steps should the solutions architect take to meet these requirements?

A.
Set the Auto Scaling group's minimum capacity to two. Deploy one On-Demand Instance in one Availability Zone and one On-Demand Instance in a second Availability Zone.
Answers
A.

Answers
C.
Set the Auto Scaling group's minimum capacity to two. Deploy four Spot Instances in one Availability Zone.
D.
Set the Auto Scaling group's minimum capacity to four Deploy two On-Demand Instances in one Availability Zone and two Spot Instances in a second Availability Zone.
Answers
D.
Set the Auto Scaling group's minimum capacity to four Deploy two On-Demand Instances in one Availability Zone and two Spot Instances in a second Availability Zone.
Suggested answer: A

Explanation:

Understanding the Requirement: The application is stateful and requires at least two EC2 instances to be running at all times, with a highly available and fault-tolerant architecture.

Analysis of Options:

Minimum capacity of two with instances in separate AZs: Ensures high availability by distributing instances across multiple AZs, fulfilling the requirement of always having two instances running.

Minimum capacity of four: Provides redundancy but is more than what is required and increases cost without additional benefit.

Spot Instances: Not suitable for a stateful application requiring guaranteed availability, as Spot Instances can be terminated at any time.

Combination of On-Demand and Spot Instances: Mixing instance types might provide cost savings but does not ensure the required availability for a stateful application.

Best Solution:

Minimum capacity of two with instances in separate AZs: This setup ensures high availability and meets the requirement with the least cost and complexity.
