AdTech Company Cuts AWS Costs 25% with TeraSky FinOps Optimization

Background

An AdTech company that turns data into advertising gold using machine learning and analytics, was processing massive data volumes to deliver laser-targeted advertising solutions. But success came with a price: their AWS infrastructure had sprawled across multiple accounts, making cost control a nightmare. Leadership recognized the need for expert assistance to manage their cloud operations, so they partnered with TeraSky for comprehensive FinOps analysis and optimization.

Challenge

The company’s AWS setup was functional but far from optimal. Their infrastructure spanned multiple accounts with fragmented operations, inconsistent configurations, and poor cost visibility.

The pain points were clear:

• S3 storage, NAT Gateway, EC2 compute, and DynamoDB costs are climbing without optimization
• No unified governance across accounts
• Machine learning workloads that needed to keep humming while costs got trimmed

They needed the right tools and actionable recommendations backed by real data – the same way they transform raw information into targeted results for their clients, they needed someone to turn their cost data into actual savings.

Solution

TeraSky rolled up its sleeves and got to work with native AWS tools and the Umbrella FinOps platform. First, they consolidated all accounts under a single AWS Organization with unified policies. They then provided a detailed FinOps Report that prioritized recommendations based on their impact and effort.

The results were impressive:

• S3 cleanup: Eliminated redundant data and implemented lifecycle policies, slashing storage by 83% and API requests by 66%
• NAT Gateway optimization: Used VPC FlowLogs to spot traffic patterns and deployed VPC Endpoints, cutting traffic by 85%
• EC2 rightsizing: Resource cleanup plus Compute Savings Plans, achieving 70% coverage

“The company’s multi-account setup made it tough to see the full cost picture,” said TeraSky’s FinOps & SM specialist, Ran Ravid. “We had to establish unified observability first, then carefully optimize each service without disrupting their machine learning workloads.”

Bottom Line

The numbers don’t lie: TeraSky’s optimization saved their client $192,000 annually, a solid 25% cost reduction. The breakdown was even more impressive: EC2 costs decreased by 18%, S3 costs plummeted by 79%, and NAT Gateway costs dropped by a whopping 80%. Meanwhile, EC2 compute costs decreased by 30%, with 43% lower hourly rates, despite a 23% increase in usage. Talk about having your cake and eating it, too.

“TeraSky cut our costs, yes. But more than that, they changed how we think about cloud spending,” said a company representative. “Their approach was data-driven, not guesswork. Plus, their deep understanding of both AWS and our business needs made them perfect partners for our transformation.”

The client now has robust FinOps processes and ongoing monitoring of the Umbrella platform. They’re positioned for growth with predictable costs and cloud economics that actually make sense, supporting their machine learning platform without incurring excessive expenses.
