Introduction
Amazon Web Services (AWS) continues to be the cloud provider of choice for enterprises worldwide. While AWS offers unmatched scalability, agility, and service breadth, cloud cost optimization has emerged as a critical priority for organizations aiming to achieve operational efficiency and sustainable growth.
In this article, we explore fresh real-world success stories from 2024 and 2025. These companies, not covered in our previous case compilations, showcase how modern FinOps practices and AWS-native and third-party tools helped them significantly cut costs, improve visibility, and align cloud usage with business objectives.
Zoom: Rebalancing costs after the pandemic surge
Challenge: Post-pandemic usage normalization left Zoom with overprovisioned compute and storage resources.
Solution: Zoom adopted AWS Graviton-based EC2 instances for better price performance and implemented S3 Intelligent Tiering to reduce cold storage costs.
Outcome:
- ~20% savings on compute through Graviton migration
- 30% reduction in storage expenses
- Improved resource allocation using AWS Cost Explorer
DoorDash: Scaling efficiently with Spot Instances
Challenge: DoorDash’s dynamic peak usage made relying solely on On-Demand EC2 instances expensive.
Solution: The company implemented a workload orchestration engine that automatically shifted eligible workloads to EC2 Spot Instances.
Outcome:
- 40% savings on compute-intensive batch jobs
- Increased reliability through fallback to On-Demand when Spot capacity was unavailable
Pinterest: Migrating to Graviton2 and serverless architectures
Challenge: Pinterest needed to handle traffic spikes cost-effectively while reducing underutilized infrastructure.
Solution: They migrated several backend services to AWS Lambda and replaced legacy EC2 with Graviton2-powered instances.
Outcome:
- 25% lower compute costs
- Better scalability and reduced idle resource costs
- Faster deployment cycles with serverless
Atlassian: Improving cost visibility through AWS organizations
Challenge: Diverse teams across Atlassian were using AWS without clear ownership or cost accountability.
Solution: Atlassian standardized tagging practices, implemented AWS Organizations with consolidated billing, and used AWS Budgets for proactive alerts.
Outcome:
- 15% drop in unallocated expenses
- Better team-level cost tracking
- Enhanced cross-department collaboration on FinOps goals
Asana: Empowering developers with FinOps culture
Challenge: Engineering teams lacked awareness of cost implications when deploying resources.
Solution: Asana rolled out internal cost dashboards using third-party FinOps tools and AWS native services like CloudWatch and Cost Anomaly Detection.
Outcome:
- 18% reduction in monthly AWS bills
- Improved cost ownership among developers
- Reduced unused or underutilized instances
Mercado Libre: Optimizing hybrid cloud strategy
Challenge: Balancing AWS spend with on-premise infrastructure in diverse Latin American markets.
Solution: They moved dev/test workloads to Spot Instances, committed to Savings Plans for steady workloads, and integrated AWS Cost and Usage Reports (CUR) into their internal analytics.
Outcome:
- 30% overall AWS cost reduction
- Streamlined hybrid workload placement
- Stronger budget forecasting
