High Availability

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
