Traffic spikes from viral content, marketing campaigns, or seasonal events can overwhelm unprepared websites. Planning for scalability ensures your site stays online and fast even during sudden surges.
Understanding traffic spikes
Traffic spikes occur when your site receives significantly more visitors than usual in a short period. Common causes include viral social media posts, email campaigns, flash sales, news coverage, or seasonal events.
Strategies for handling traffic spikes
1. Auto-scaling infrastructure
Auto-scaling automatically adds server resources when traffic increases and scales down when demand drops. This ensures you only pay for what you use while maintaining performance.
2. Caching layers
- Page caching – Serve static HTML versions of dynamic pages
- Object caching – Cache database queries and API responses
- CDN caching – Distribute static assets globally
- Browser caching – Store resources locally on visitor devices
3. Content Delivery Network (CDN)
A CDN serves your content from edge servers closer to visitors, reducing load on your origin server and improving response times during traffic spikes.
4. Database optimization
- Optimize slow queries and add proper indexes
- Use read replicas for database-heavy applications
- Implement query caching
