A company is moving its development and test environments to AWS to increase agility and reduce cost. Because these are not production workloads and the servers are not fully utilized, occasional unavailability is acceptable.
What is the MOST cost-effective Amazon EC2 pricing model that will meet these requirements?
For development and test environments where occasional unavailability is acceptable and cost-efficiency is a priority, Spot Instances are the most cost-effective option. They allow you to bid on spare Amazon EC2 capacity, which can provide substantial savings compared to On-Demand pricing. While Spot Instances can be terminated by AWS with little notice if the capacity is needed for other applications, this is acceptable in non-production environments where resilience and unavailability tolerance are higher.
