FinOps & Economics Research Environment - Getting Started

Time to Complete: 20 minutes Cost: $8-14 for tutorial Skill Level: Beginner (no cloud experience needed)

What You’ll Build

By the end of this guide, you’ll have a working financial and economic research environment that can:

Analyze financial markets and economic data
Build econometric models and financial forecasting systems
Process large-scale financial datasets and time series
Implement risk management and portfolio optimization models

Meet Dr. Rachel Chen

Dr. Rachel Chen is a financial economist at Federal Reserve Bank. She analyzes market data but waits days for secure computing resources. Each economic model requires processing millions of financial transactions and market indicators.

Before: 3-day waits + 8-hour analysis = 11 days per economic study After: 15-minute setup + 2-hour analysis = same day results Time Saved: 96% faster financial analysis cycle Cost Savings: $400/month vs $1,500 institutional allocation

Before You Start

What You Need

AWS account (free to create)
Credit card for AWS billing (charged only for what you use)

20 minutes of uninterrupted time

Cost Expectations

Tutorial cost: $8-14 (we’ll clean up resources when done)
Daily research cost: $12-28 per day when actively analyzing
Monthly estimate: $150-350 per month for typical usage
Free tier: Some compute included free for first 12 months

Skills Needed

Basic computer use (creating folders, installing software)
Copy and paste commands
No finance or economics experience required

Step 1: Install AWS Research Wizard

Choose your operating system:

macOS/Linux

curl -fsSL https://install.aws-research-wizard.com | sh

Windows

Download from: https://github.com/aws-research-wizard/releases/latest

What this does: Installs the research wizard command-line tool on your computer.

Expected result: You should see “Installation successful” message.

⚠️ If you see “command not found”: Close and reopen your terminal, then try again.

Step 2: Set Up AWS Account

If you don’t have an AWS account:

Go to aws.amazon.com
Click “Create an AWS Account”
Follow the signup process
Important: Choose the free tier options

What this does: Creates your personal cloud computing account.

Expected result: You receive email confirmation from AWS.

💰 Cost note: Account creation is free. You only pay for resources you use.

Step 3: Configure Your Credentials

aws-research-wizard config setup

The wizard will ask for:

AWS Access Key: Found in AWS Console → Security Credentials
Secret Key: Created with your access key
Region: Choose us-east-1 (recommended for financial data with good market data access)

What this does: Connects the research wizard to your AWS account.

Expected result: “✅ AWS credentials configured successfully”

⚠️ If you see “Access Denied”: Double-check your access key and secret key are correct.

Step 4: Validate Your Setup

aws-research-wizard deploy validate --domain finops_economics --region us-east-1

What this does: Checks that everything is working before we spend money.

Expected result:

✅ AWS credentials valid
✅ Domain configuration valid: finops_economics
✅ Region valid: us-east-1 (6 availability zones)
🎉 All validations passed!

Step 5: Deploy Your FinOps Environment

aws-research-wizard deploy start --domain finops_economics --region us-east-1 --instance m6i.large

What this does: Creates your financial research environment optimized for economic data analysis.

This will take: 5-7 minutes

Expected result:

🎉 Deployment completed successfully!

Deployment Details:
  Instance ID: i-1234567890abcdef0
  Public IP: 12.34.56.78
  SSH Command: ssh -i ~/.ssh/id_rsa ubuntu@12.34.56.78
  CPU: 2 cores for financial modeling
  Memory: 8GB RAM for large datasets

💰 Billing starts now: Your environment costs about $0.19 per hour while running.

Step 6: Connect to Your Environment

Use the SSH command from the previous step:

ssh -i ~/.ssh/id_rsa ubuntu@12.34.56.78

What this does: Connects you to your financial research computer in the cloud.

Expected result: You see a command prompt like ubuntu@ip-10-0-1-123:~$

⚠️ If connection fails: Your computer might block SSH. Try adding -o StrictHostKeyChecking=no to the command.

Step 7: Explore Your Financial Tools

Step 9: Using Your Own Finops Economics Data

Instead of the tutorial data, you can analyze your own finops economics datasets:

Upload Your Data

# Option 1: Upload from your local computer
scp -i ~/.ssh/id_rsa your_data_file.* ec2-user@12.34.56.78:~/finops_economics-tutorial/

# Option 2: Download from your institution's server
wget https://your-institution.edu/data/research_data.csv

# Option 3: Access your AWS S3 bucket
aws s3 cp s3://your-research-bucket/finops_economics-data/ . --recursive

Common Data Formats Supported

Financial data (.csv, .xlsx): Market data, pricing, and economic indicators
Cost reports (.json, .csv): Cloud billing and resource usage data
Time series (.csv, .json): Economic forecasts and financial modeling
Transaction data (.csv, .parquet): Trading records and financial flows
Optimization data (.json, .lp): Linear programming and operations research

Replace Tutorial Commands

Simply substitute your filenames in any tutorial command:

# Instead of tutorial data:
python3 cost_analysis.py billing_data.csv

# Use your data:
python3 cost_analysis.py YOUR_FINANCIAL_DATA.csv

Data Size Considerations

Small datasets (<10 GB): Process directly on the instance
Large datasets (10-100 GB): Use S3 for storage, process in chunks
Very large datasets (>100 GB): Consider multi-node setup or data preprocessing

Step 10: Monitor Your Costs

Check your current spending:

exit  # Exit SSH session first
aws-research-wizard monitor costs --region us-east-1

Expected result: Shows costs so far (should be under $5 for this tutorial)

Step 11: Clean Up (Important!)

When you’re done experimenting:

aws-research-wizard deploy delete --region us-east-1

Type y when prompted.

What this does: Stops billing by removing your cloud resources.

💰 Important: Always clean up to avoid ongoing charges.

Expected result: “🗑️ Deletion completed successfully”

Understanding Your Costs

What You’re Paying For

Compute: $0.19 per hour for general-purpose instance while environment is running
Storage: $0.10 per GB per month for financial datasets you save
Data Transfer: Usually free for financial research data amounts

Cost Control Tips

Always delete environments when not needed
Use spot instances for 60% savings (advanced)
Store large datasets in S3, not on the instance
Process data efficiently to minimize compute time

Typical Monthly Costs by Usage

Light use (10 hours/week): $75-150
Medium use (3 hours/day): $150-300
Heavy use (6 hours/day): $300-600

Troubleshooting

Common Issues

Problem: “QuantLib import error” during financial analysis Solution: Check QuantLib installation: python -c "import QuantLib" and reinstall if needed Prevention: Wait 5-7 minutes after deployment for all financial packages to initialize

Problem: “Convergence error” in optimization algorithms Solution: Try different starting points or reduce convergence tolerance Prevention: Check input data quality and parameter bounds

Problem: “Memory error” during large portfolio optimization Solution: Reduce number of assets or use a larger instance type Prevention: Monitor memory usage with htop during optimization

Problem: “Data format error” when loading financial data Solution: Verify date formats and missing value handling Prevention: Always validate financial data before analysis
