Ensuring Scalability in a Trading Application

Key principles for scalability include:

• Microservices Architecture: Break down the application into smaller, independent services that can be developed and deployed separately.
• Load Balancing: Use load balancers to distribute incoming traffic across multiple servers efficiently.
• Database Sharding: Implement sharding to divide databases into smaller, manageable pieces for balanced data access.
• Caching Strategies: Integrate caching mechanisms like Redis to speed up data retrieval and reduce server load.
• Horizontal Scaling: Design the application to easily add more servers as demand increases, rather than relying solely on upgrading existing hardware.
