  Even if it mentions rolling with additional batches, D would still not be the correct answer. The question asks what is the MOST COST EFFECTIVE way, rolling with additional batch of 2 means the instance count goes to 6 at some moments as opose to the 5 in option C, which makes it still more cost effective

• Chose C2

  A) Eliminated - Permanently increasing the desired capacity to six EC2 instances incurs unnecessary ongoing costs. B) Eliminated - Traffic splitting is primarily used for canary testing or gradual traffic shifting. It does not guarantee maintaining the desired instance capacity during deployment. D) Eliminated - A rolling deployment with a batch size of 2 means two instances are replaced at a time. With a fixed capacity of 5 instances, this would temporarily reduce the number of running instances to 3, causing performance degradation.

  C) Batch Size of 1: Specifies that only one instance will be updated at a time, minimizing downtime and maintaining the required instance capacity for performance. Rolling with additional Batch - This deployment strategy adds an extra batch of EC2 instances during deployment. After updating one batch, the additional instances are terminated, ensuring cost efficiency.
