• Use Redis for caching frequently accessed data.

Security

• Securely store and transmit user data.
• Implement measures against abusive behavior.

Scalability

• Use RabbitMQ for handling asynchronous tasks.
• Implement Nginx as a load balancer.

Tech Stacks and Justification

• Backend Language: Golang (High performance, simplicity, efficiency).
• Database: PostgreSQL (Robust, open-source).
• ORM: GORM (Simplifies database interactions, PostgreSQL support).
• Authentication: JWT (Stateless, secure).
• Cache: Redis (Caching data).
• Load Balancer: Nginx (Distribute incoming traffic).

Installation with Docker

1. Clone the repository:

   git clone [repository_url]
   cd [repository_directory]
   

2. Build the Docker containers:

   docker-compose build
   

3. Run the application:

    docker-compose up -d
   

4. Shut down the application:

   docker-compose down
   

5. Restart the application (in case of errors or changes):

   docker-compose restart
   

Replace [repository_url] and [repository_directory] with your actual repository URL and directory. Users can follow these instructions to clone, build, run, shut down, and restart the Dating App Backend using Docker.
