Faasera Documentation

Cloud Functions Integration Guide

Faasera supports seamless deployment of its core components via cloud-native Functions-as-a-Service (FaaS) on AWS, Azure, and Google Cloud. This guide covers deploying Faasera Profiler and Masking services using cloud functions.

---

Supported Platforms

Cloud Platform	Function Type	Use Cases
AWS	Lambda	Real-time masking/profiling via API Gateway
Azure	Azure Functions	Batch & stream data compliance workflows
Google Cloud	Cloud Functions	Lightweight API-based masking for GCS/BigQuery

---

General Setup

All Faasera cloud functions follow the same deployment pattern:

1. Package your Faasera JAR or Python function.
2. Define your cloud-specific entry point.
3. Deploy via CLI or UI.
4. Connect triggers (HTTP, storage events, etc.).

---

Package Structure

For Java-based functions:

/faasera-function/
├── build/libs/faasera.jar
├── config/
│   └── policy.json
└── handler/
    └── FunctionHandler.java

For Python:

/faasera-function/
├── main.py
├── requirements.txt
└── config/
    └── policy.json

AWS Lambda

Deployment Steps

1. Build ZIP with dependencies.
2. Create IAM Role with Lambda + VPC access (optional).
3. Deploy using:

aws lambda create-function   --function-name FaaseraFunction   --runtime java11   --handler com.faasera.FunctionHandler   --zip-file fileb://faasera.zip   --role arn:aws:iam::123456789:role/lambda-role

1. Optional: Attach API Gateway or EventBridge for triggers.

---

Azure Functions

Supported Types

• HTTP-triggered
• Timer-triggered (for scheduled profiling/masking)
• Blob-triggered (data lake file masking)

Deployment

func azure functionapp publish faasera-comply-function

Ensure you set the FUNCTIONS_WORKER_RUNTIME to java or python as per your implementation.

---

Google Cloud Functions

Deployment

gcloud functions deploy faasera-function   --runtime java11   --trigger-http   --entry-point com.faasera.FunctionHandler   --memory 512MB

---

Configuration Options

Pass configurations using:

• Environment variables
• Encrypted files (with KMS)
• Secrets Manager (AWS) or Key Vault (Azure)

---

Testing

All functions support:

• REST API testing using Postman/curl
• Event-driven triggers with test data
• Cloud logs via CloudWatch, Application Insights, or GCP Logs

---

Example Payload (Masking)

{
  "requestId": "xyz-123",
  "mode": "MULTI_RULE_BATCH",
  "records": [
    {
      "ruleName": "EMAIL_ADDRESS",
      "value": "john.doe@example.com"
    }
  ]
}
