How a FinOps Approach with Legend Can Slash Your Multi-Cloud AWS/Azure/GCP Costs

Ever wonder how your team’s coding habits affect your cloud bill? I’ve spent years helping companies connect the dots between developer workflows and cloud spending. The right tools can make code faster, deployments smoother, and your AWS, Azure, or GCP costs drop fast.

Understanding the FinOps Philosophy

FinOps isn’t a fancy term—it’s about making cloud spending everyone’s business. As someone knee-deep in cloud costs daily, I’ve watched teams go from frustrated by surprise bills to actually controlling their spending. It’s about getting finance and tech on the same page so cloud costs match what the business needs.

The Core Tenets of FinOps

• Visibility: See every dollar spent across AWS, Azure, and GCP to catch waste early.
• Accountability: Set budgets by team or project so overspending gets caught before it’s a problem.
• Optimization: Tweak resources as workloads change, using automation to save time.
• Forecasting: Use smart predictions to plan budgets and avoid unexpected costs.

Introducing Legend: The Cloud Cost Optimization Tool

Legend is a cloud cost platform that uses real-time data and machine learning to help you save on AWS, Azure, and GCP. It pulls together your entire multi-cloud setup in one place, showing where money’s being wasted and how to fix it.

Real-Time Cost Monitoring

Legend’s dashboard shows your cloud spend as it happens—broken down by service, region, and team. If a cost spike hits, you’ll know immediately and can act fast.

Automated Recommendations

Legend looks at your usage and suggests ways to save, like:

• Shrinking oversized EC2 instances on AWS.
• Switching to reserved instances or savings plans.
• Reducing Azure VM sizes or turning off idle resources.
• Adjusting GCP’s Custom Machine Types for workloads that change.

Integration with CI/CD Pipelines

Legend fits right into your CI/CD workflows. It checks for cost spikes during deployments—like flagging a new microservice that goes over budget before it’s live.

Case Study: Reducing AWS Costs with Legend

One tech company cut its AWS bill by 30% in three months with Legend. Here’s how they did it.

Initial Cloud Assessment

The FinOps team used Legend to audit their AWS setup. They found:

• 50 EC2 instances running way more power than needed (t3.xlarge).
• 200 GB of S3 storage no one was using.
• Several Lambda functions taking longer than necessary.

Implementation of Cost-Saving Measures

Based on Legend’s findings, the team made these changes:

• Resized EC2 Instances: Dropped t3.xlarge instances to t3.large, saving 25%.
• Archived Unused S3 Data: Moved 200 GB to S3 Glacier, cutting storage costs by 60%.
• Optimized Lambda Functions: Rewrote code to speed up execution by 30%, as shown below.


// Before optimization
const handler = async (event) => {
const response = await processData(event);
return response;
};

// After optimization
const handler = async (event) => {
const response = await optimizedProcessData(event);
return response;
};

const optimizedProcessData = async (event) => {
// Refactored logic to reduce execution time
// ...
};


Results and Ongoing Monitoring

Three months in, they saved 30% on AWS—over $20,000 a month. The team now uses Legend to keep those savings as their cloud needs grow.

Optimizing Serverless Computing Costs Across AWS, Azure, and GCP

Serverless is great for fast development, but costs can sneak up if you’re not careful. Legend helps track serverless spending with details on function runs, triggers, and resource use.

Right-Sizing Serverless Resources

Legend checks execution time, memory use, and how often functions run to recommend the best settings. For example, if a Lambda function only uses half its memory, Legend will suggest reducing it.

Monitoring Event-Driven Architectures

Event-driven setups like AWS Lambda, Azure Functions, or Google Cloud Functions can get expensive fast. Legend watches event triggers and suggests ways to cut costs, such as:

• Filtering events to process only what matters.
• Using batch processing to run functions fewer times.

Actionable Takeaways for FinOps Practitioners

Here’s what I tell teams to do to start saving now.

Start with a Cloud Cost Audit

Run a full audit with Legend to see where your cloud spend is going and where you can cut waste.

Establish Cost Allocation Tags

Use tags to track spending by project, team, or app. This makes it easy to see who’s spending what and plan budgets better.

Automate Cost Management

Set up Legend to automatically enforce rules—like shutting down idle resources or resizing underused instances.

Educate Developers and Teams

Host training for developers on how their code affects cloud costs. When teams understand the financial impact, they make better choices.

Continuously Monitor and Optimize

Cloud cost management isn’t a one-time job. Use Legend to keep watching your spend and adjust as your needs change.

Conclusion

Adding Legend to your FinOps plan helps you save on AWS, Azure, and GCP costs. With real-time data, smart suggestions, and CI/CD integration, it gives teams the power to cut costs without sacrificing performance. I’ve seen it work across companies of all sizes—turning cloud spending from a headache into a controlled, strategic part of operations. The key is making cost awareness part of your culture, staying on top of usage, and using automation to keep saving. With Legend, you’re not just cutting costs—you’re building smarter cloud operations for the long run.
