Cloud adoption has never been higher, and neither has cloud waste. Teams move fast, deploy faster, and unknowingly spend even faster. Somewhere between Kubernetes abstractions, auto-generated infrastructure, and vague monthly bills, the relationship between engineering decisions and cloud costs breaks down.
Over the last year, both the FinOps community and academic research have converged on a simple reality: engineering teams need real-time cost visibility, not spreadsheets after the fact. And they need cost-aware automation built directly into the systems they operate.
This is where a powerful trio emerges—Karpenter, Spot Instances, and Cost-Per-Feature Dashboards. Together, they form a “FinOps you can actually ship” model: automated, measurable, developer-friendly, and designed for real-world cloud efficiency.
Why FinOps Needs a Practical, Engineering-First Approach
Traditional FinOps efforts often focus on reporting or budgeting. But reporting cloud waste after it happens doesn’t prevent it. The shift to Kubernetes added another layer of complexity—clusters abstract everything, making it extremely hard to know:
Which workloads cause cost spikes
Why nodes are over-provisioned
How much each feature actually costs to run
Research over the last two years repeatedly highlights that Kubernetes environments are among the easiest places to lose cost visibility. Static node groups, over-provisioned instances, and “just-in-case” resource requests quietly burn money in the background.
FinOps today isn’t just about optimizing bills—it’s about aligning engineering, product, and finance around shared metrics. That requires tools that plug into engineering workflows, not finance dashboards.
Karpenter: Autoscaling That Actually Reduces Costs
Enter Karpenter, the open-source Kubernetes autoscaler built to solve real efficiency problems.
Unlike older node group–based autoscalers, Karpenter looks directly at pending pods and provisions right-sized compute nodes on the fly. Instead of guessing what instance size you might need, Karpenter chooses the best fit from a wide range of instance types, sizes, and Availability Zones.
Industry teams like Slack have publicly shared cost reductions from migrating to Karpenter, and research echoes the same pattern:
Dynamic autoscaling improves cluster utilization by 20–40% while lowering idle capacity.
The reasons are straightforward:
It bin-packs workloads with better efficiency
It eliminates the rigid boundaries of node groups
It provisions only what is needed—and terminates unused nodes quickly
It takes full advantage of diversified instance pools
In a world where infrastructure changes minute-to-minute, having autoscaling that adapts instantly is a massive FinOps win.
Spot Instances: The Underrated FinOps Multiplier
AWS Spot Instances provide discounts up to 70–90%. Every FinOps report highlights this. Every research paper that studies cloud economics confirms it. The only blocker has always been one problem: interruptions.
But that’s exactly where Karpenter + Spot shines.
Karpenter uses a price-and-capacity-optimized strategy that chooses Spot pools with high availability and low interruption risk. And if a Spot pool runs out, it automatically falls back to another type or to On-Demand. In practice, this creates a highly resilient, cost-optimized compute layer that can handle real production workloads.
Modern research shows that using:
1. multi-AZ
2. multi-size
3. multi-family diversification
significantly reduces the chance that Spot interruptions affect workloads. And Karpenter handles all of those choices automatically.
Together, Spot Instances and Karpenter form one of the highest ROI moves any FinOps team can make.
Cost-Per-Feature Dashboards: Making Costs Make Sense
Even with efficient autoscaling and Spot savings, teams still struggle to answer the question that matters most to the business:
“What is the cost of this feature?”
This is where cost-per-feature dashboards become game changers.
Instead of vague infrastructure bills, teams can now view:
1. Cost per feature
2. Cost per microservice
3. Cost per customer
4. Cost per deployment
This level of granularity does more than inform—it changes engineering behavior. Research shows that when developers see the financial impact of their design choices, over-provisioning drops by up to 30%.
These dashboards empower teams to make smarter decisions, such as:
retiring unused or expensive features
moving premium features behind paid plans
right-sizing microservices before costs explode
validating architectural changes with cost impact data
Cost-per-feature visibility turns FinOps into an engineering tool, not a finance report.
Shifting FinOps Left: Connecting It All in CI/CD
Modern teams are integrating FinOps directly into CI/CD. Tools like Infracost or Kubecost APIs show the cost impact of a pull request before it is merged. Multiple case studies show this simple visibility reduces wasteful changes dramatically.
FinOps becomes a natural part of the development workflow instead of a monthly surprise.
A FinOps Framework You Can Actually Ship
Bringing everything together, we get a practical, deployable FinOps model:
Karpenter for real-time, efficient autoscaling
Spot Instances for massive cost reductions
Cost-per-feature dashboards for business-aligned visibility
The loop becomes continuous:
Scale efficiently → Save more → Measure impact → Improve continuously
Organizations that adopt this combined approach report:
30–70% overall cloud savings
higher cluster utilization
improved predictability
stronger collaboration between engineering and finance
FinOps stops being reactive and becomes something you actively ship, measure, and optimize—just like your software.

Frequently Asked Questions
Q1: What is FinOps, and why is it important for cloud cost management with Brigita?
A1: FinOps, or Cloud Financial Operations, is a methodology that aligns engineering, product, and finance teams to manage cloud costs effectively. With Brigita’s engineering-first FinOps approach, teams gain real-time cost visibility, optimize resources, and reduce cloud waste, achieving 30–70% cost savings in Kubernetes and AWS environments.
Q2: How does Karpenter from Brigita help reduce cloud costs?
A2: Brigita leverages Karpenter, the open-source Kubernetes autoscaler, to dynamically provision right-sized compute nodes based on workload demand. By eliminating over-provisioning, bin-packing workloads efficiently, and utilizing diversified instance types, Karpenter improves cluster utilization by 20–40%, significantly lowering idle capacity and overall cloud spend.
Q3: Can Spot Instances be used safely for production workloads with Brigita’s approach?
A3: Yes! Brigita’s FinOps model combines Karpenter with AWS Spot Instances to deliver up to 90% cost savings while maintaining production reliability. Karpenter selects low-interruption Spot pools automatically and falls back to On-Demand instances if needed, ensuring resilient, cost-optimized compute across multi-AZ and multi-family configurations.
Q4: What are cost-per-feature dashboards, and why should teams use Brigita’s solution?
A4: Brigita’s cost-per-feature dashboards provide granular insights into the actual cloud cost of features, microservices, customers, and deployments. This empowers developers and product teams to make data-driven decisions, retire unused features, right-size microservices, and validate architectural changes, turning FinOps into a proactive engineering tool rather than just a finance report.
