Best practice 14.2 – Consult with your finance team and determine optimal payment models
If you use reserved-capacity pricing options, you can reduce the infrastructure cost without modifying your workload architectures. Collaborate with your finance team on the planning and use of purchase discounts.
Make informed decisions regarding various cost factors. These include the amount of capacity to reserve, the reserve term length, and the choice of upfront payments for their corresponding discount rates. The finance team should assist your team in determining the best long-term and reserved-capacity pricing options. This is because these options affect your IT budget plans, such as which month is the right moment to pay an upfront charge.
Suggestion 14.2.1 – Consolidate the infrastructure usage to maximize the coverage of reserved capacity price options
Reserved Instances and Savings Plan purchases apply automatically to the resources that will receive the largest discount benefit. To maximize your discount utilization, consolidate resources in accounts within an AWS Organization structure. Allow the purchase commitments to apply to other AWS accounts within your organization if they are unused in the account for which they are purchased.
