Reserved Instances (RIs)

Save when you reserve

Save Money and Maintain Flexibility

For certain services like Amazon EC2 and Amazon RDS, you can invest in reserved capacity. With Reserved Instances, you can save up to 75% over equivalent on-demand capacity. Reserved Instances are available in 3 options – All up-front (AURI), partial up-front (PURI) or no upfront payments (NURI).

When you buy Reserved Instances, the larger the upfront payment, the greater the discount. To maximize your savings, you can pay all up-front and receive the largest discount. Partial up-front RI's offer lower discounts but give you the option to spend less up front. Lastly, you can choose to spend nothing up front and receive a smaller discount, but allowing you to free up capital to spend in other projects.

By using reserved capacity, your organization can minimize risks, more predictably manage budgets, and comply with policies that require longer-term commitments.

Rightsizing is the most effective way to control cloud costs. It involves continually analyzing instance performance and usage needs and patterns—and then turning off idle instances and rightsizing instances that are either overprovisioned or poorly matched to the workload. Because your resource needs are always changing, rightsizing must become an ongoing process to continually achieve cost optimization. You can make rightsizing a smooth process by establishing a rightsizing schedule for each team, enforcing tagging for all instances, and taking full advantage of the powerful tools that AWS and others provide to simplify resource monitoring and analysis.
