High Availability:

  • Use load balancers to distribute traffic across multiple servers
  • Set up redundancy with failover systems and multiple availability zones
  • Use managed databases with replicas for disaster recovery

Scalability:

  • Implement horizontal scaling by adding more instances
  • Use auto-scaling services like AWS Auto Scaling or Kubernetes
  • Cache frequently accessed data (e.g., using Redis or Memcached)

Other Best Practices:

  • Optimize database queries and use indexing
  • Implement rate limiting and throttling to handle surges
