DPC2022: Scaling: from 0 to 20 million users

Don’t bother optimizing prematurely, until necessary

• Only optimize when experiencing problems
• Start with simple solutions, like increasing cache and testing
• Validate performance before making changes

Use a hybrid cloud approach

• Combine on-premise and cloud infrastructure for flexibility and scalability
• This allows for controlled costs and optimal resource utilization

Avoid inefficient data storage

• Use a document-based database like MongoDB for high-traffic applications
• Consider data consistency and versioning when using document-based databases
• Avoid improper data retrieval and modeling

Leverage caching and content delivery networks

• Use a caching layer to reduce load on back-end servers
• Implement a content delivery network (CDN) to distribute cached content
• Use edge computing for faster response times

Optimize for mobile users

• Consider user location and latency when optimizing for mobile users
• Use a data center closest to the user for better performance
• Optimize for different networks and devices

Monitor and analyze performance

• Use monitoring tools to identify performance bottlenecks
• Analyze logs and metrics to optimize performance
• Use caching and content delivery networks to reduce traffic to back-end servers
