Funcify

Funcify is a lightweight Function-as-a-Service (FaaS) platform that allows you to deploy and run isolated serverless functions in the cloud. With auto-scaling capabilities and an intuitive CLI, Funcify simplifies the deployment and execution of functions while optimizing resource utilization.

---

Features

• Deploy Functions: Upload your functions to the cloud, deploy them, and get a URL for execution.
• Run Functions: Execute your deployed functions directly using the provided URL.
• Auto Scaling: Automatically scales up or down based on system load using RabbitMQ and Docker containers.
• Logs and Metrics: Access detailed logs and performance metrics for each function.
• CLI Tool: Simplify interaction with the platform for authentication, deployment, and execution.

Architecture

1. Users:

   • Users interact with the platform using a CLI or direct API calls.

2. Blob Storage:

   • Stores function code uploaded by users (e.g., AWS S3).

3. Main Server:

   • Handles metadata storage in the database.
   • Consumes tasks from the queue.
   • Dynamically launches Docker containers to execute the functions.

4. Message Queue:

   • RabbitMQ/Kafka manages function execution requests.

5. Database:

   • Stores metadata about deployed functions (e.g., user details, function endpoints).

6. Execution Environment:

   • Launches Docker containers with suitable runtime environments to execute the code.

7. Auto Scaling:

   • Horizontally scales the main server instances based on queue length and demand.

• Queue System: RabbitMQ/Kafka
• Containerization: Docker
• Cloud Storage: AWS S3 (or equivalent)(currently stores file locally)
• Database: MongoDB (or any NoSQL/SQL database)
• CLI Tool: Node.js-based CLI interface

Installation

Backend Setup

1. Clone the repository:

   git clone https://github.com/Sahiiil1406/Funcify.git
   cd funcify

2. Install dependencies:

   npm install

3. Configure environment variables:

   • RabbitMQ/Kafka connection details
   • Database URL -PORT number

4. Start the server:

   npm start

CLI Tool Setup

1. Install the CLI globally:

   npm install -g 

2. Authenticate and start deploying functions:

   funcify login
   funcify deploy --file <path-to-function-file>

Usage

Deploy a Function

Use the CLI to deploy your function:

funcify deploy --file <path-to-function.js>

Run a Function

Execute the deployed function using the provided URL:

curl -X POST <function-url> -d '{"key": "value"}' -H "Content-Type: application/json"

View Logs

Retrieve logs for your function:

funcify logs --function <function-name>
