Architecting High-Throughput Web Applications with Laravel 11 and Redis
LEAV SIS
Software Developer • Founder of LS Tech Cambodia
A detailed architectural walkthrough on handling tens of thousands of concurrent requests using queue workers, atomic locks, and Redis caching layers.
Modern web applications demand speed, reliability, and graceful handling of sudden load spikes.
In this article, I share key patterns implemented across client projects at LS Tech Cambodia. We explore database query minimization with eager loading, leveraging Redis atomic locks to prevent race conditions during high-volume transactions, and utilizing Laravel Horizon for queue supervision.
Key takeaways include optimizing index strategies, setting up read/write replicas, and architecting asynchronous event buses that keep end-user response times sub-100ms.
