A company would like to optimize Amazon Elastic Compute Cloud (Amazon EC2) costs. Which of the following actions can help with this task?

Solution
The two actions that can help a company optimize Amazon Elastic Compute Cloud (Amazon EC2) costs are:
D. Set up Auto Scaling groups to align the number of instances with the demand: Auto Scaling groups allow you to scale your application in response to demand. This means you can increase the number of EC2 instances during demand spikes to maintain performance, and decrease capacity during lulls to reduce costs.
E. Purchase Amazon EC2 Reserved instances (RIs): Reserved Instances provide a significant discount (up to 75%) compared to On-Demand pricing and provide a capacity reservation when used in a specific Availability Zone. This can lead to significant cost savings over time.
