In todayโs cloud-native world, efficiently scaling your AWS infrastructure is crucial to ensure your applications can handle sudden surges in traffic without performance degradation. Whether youโre preparing for a high-traffic event (HT) or aiming for resilient, cost-effective scaling, implementing the right strategies is key.

A foundational practice for scalability is placing EC2 instances in an ๐๐๐๐ผ ๐ฆ๐ฐ๐ฎ๐น๐ถ๐ป๐ด ๐๐ฟ๐ผ๐๐ฝ (๐๐ฆ๐) behind an ๐๐ฝ๐ฝ๐น๐ถ๐ฐ๐ฎ๐๐ถ๐ผ๐ป ๐๐ผ๐ฎ๐ฑ ๐๐ฎ๐น๐ฎ๐ป๐ฐ๐ฒ๐ฟ (๐๐๐). This ensures dynamic scaling based on demand, distributing incoming traffic evenly across instances.

On high-traffic days, relying on AWSโs default ALB scaling may not be sufficient. AWS automatically scales ALBs based on demand, but sudden bursts can cause performance bottlenecks. ๐ฃ๐ฟ๐ฒ-๐๐ฎ๐ฟ๐บ๐ถ๐ป๐ด the ALB ensures it is already scaled to handle expected peak loads, reducing latency and improving responsiveness.

While ASGs dynamically scale based on metrics, incorporating ๐๐ฐ๐ต๐ฒ๐ฑ๐๐น๐ฒ๐ฑ ๐๐ฐ๐ฎ๐น๐ถ๐ป๐ด allows you to pre-provision instances before peak hours. This approach ensures that sufficient EC2 instances are available to absorb burst traffic (BT) without delays caused by on-the-fly scaling.

Breaking a monolithic application into ๐บ๐ถ๐ฐ๐ฟ๐ผ๐๐ฒ๐ฟ๐๐ถ๐ฐ๐ฒ๐ allows independent scaling of different components. Services experiencing high demand can scale separately, optimizing costs and performance.

Scaling AWS infrastructure for high-traffic events requires a mix of proactive planning, automated scaling, and performance optimizations. By combining ASGs, ALBs, pre-warming strategies, and intelligent resource allocation, you can ensure seamless user experiences even under extreme load conditions.
