AWS reserved instance purchase and use 2022
When should you purchase AWS through Savings Plans, and when is the best strategy to buy reserved instances?
Major considerations include:
• AWS Saving Plans are commitments
• Reserved Instances are commitments to a specific amount of utilization
• Currently, only EC2, and Fargate are eligible for AWS Saving Plans
• Businesses using Reserved Instances (RIs) to save money on the cost of RDS, Redshift, and ElastiCache are not currently able to use Savings Plans against these instances
• Most enterprises should utilize a mixture of RIs and Savings Plans, especially if they have made previous RI commitments
• It is not currently possible to resell underutilized Savings Plans
• One major advantage of AWS Savings Plans is they replace the manual conversion processes traditionally associated with Convertible Reserved Instances
