AWS has announced that starting January 15, 2024, it will no longer allow customers to resell Reserved Instances acquired at a discount on the Amazon EC2 Reserved Instance Marketplace. However, customers can still list their discounted RIs for sale on the Marketplace until January 15, 2024. This change is due to Section 5.5 of the AWS service agreements, which prohibits the sale of discounted RIs. To overcome this ban, customers can consider using alternative pricing options such as AWS Savings Plans or looking beyond commitment for cost savings by optimizing their infrastructure and workload. CAST AI is a fully automated cloud cost optimization platform that generates cost savings of 60% and more without vendor lock-in.
