Frequently Asked Questions

What makes good backend architecture? +

Good backend architecture balances several factors: scalability to handle growth, maintainability for long-term code health, security to protect data, performance for user experience, and reliability to minimize downtime. These considerations should guide technology choices and design decisions.

How important is database design? +

Database design is foundational. Poor database design creates performance problems, scalability limits, and data integrity issues that are expensive to fix later. Proper normalization, indexing, and schema design from the start prevent problems and enable growth.

What's the difference between REST and GraphQL? +

REST uses multiple endpoints and HTTP methods for operations. GraphQL uses a single endpoint with a query language for flexible data retrieval. REST is simpler and more cacheable; GraphQL is more flexible but requires client-side parsing. Choice depends on use case requirements.

How do you ensure backend security? +

Security requires multiple layers: input validation to prevent injection attacks, authentication to verify user identity, authorization to control access, encryption for sensitive data, rate limiting to prevent abuse, HTTPS for data in transit, and regular security audits and updates.

What's the cost of backend development? +

Backend development costs depend on complexity, technology choices, and team experience. Simple APIs start at ₹25,000, while complex microservices systems can range from ₹200,000-₹1,000,000+. Get detailed specifications and multiple quotes to compare options.
