RightSpend delivers Commitment Free Discounts (CFDs) for AWS EC2 — up to 55% savings versus on-demand pricing, with no lock-in and no upfront payment. Most AWS discount strategies force a trade-off: commit for 1–3 years to get good rates, or stay flexible and overpay. RightSpend removes that...

As answered by people managing Apache CloudStack and RightSpend.ai.
RightSpend.ai's answer:
RightSpend invented Commitment Free Discounts which are a way to get up to 55% off AWS EC2 costs without any lock-in period or upfront commitment. That's the same discount level as a 3-year Reserved Instance, with full flexibility to scale up or down anytime. No other platform offers this combination of savings depth and zero commitment.
RightSpend.ai's answer:
FinOps teams and engineering leaders at mid-to-large enterprises running significant AWS EC2 workloads, typically $750K+ in annual AWS spend. It suits companies that want strong EC2 discount rates but can't or won't lock into multi-year commitments due to growth, uncertainty, or variable workloads.
RightSpend.ai's answer:
RightSpend was built by the team behind CloudFix, which manages AWS cost optimization across hundreds of enterprise accounts. They repeatedly saw the same problem: customers were leaving EC2 savings on the table because Reserved Instances required commitment they weren't comfortable making. RightSpend was built to solve that, delivering RI-level discounts without the RI-level risk.
RightSpend.ai's answer:
ProsperOps, Zesty, and nOps all optimize Reserved Instances or Savings Plans meaning that you still carry commitment risk. RightSpend eliminates that entirely. You get comparable savings rates with no lock-in, no capacity planning, and no overcommitment risk. It also works alongside existing RIs and Savings Plans rather than replacing them, so there's no disruption to what's already working.
RightSpend.ai's answer:
RightSpend is built natively on AWS. It integrates via secure, read-only IAM roles with no long-term credentials or infrastructure changes required. The optimization engine uses machine learning for real-time usage pattern analysis and predictive discount management. Available on AWS Marketplace as RightSpend Flex.
