Design and Implementation of a Scalable Web Application Using AWS Cloud Infrastructure

This review examined the design and implementation considerations of scalable web applications using AWS cloud infrastructure. The analysis indicates that scalability is a system-level property produced by coordinated architectural and operational decisions. Compute capacity, traffic distribution, storage, databases, security, observability, and deployment automation must be designed together. Horizontal scaling and stateless application tiers provide a strong foundation, while managed services can reduce operational effort. Monolithic, microservices, containerized, and serverless architectures each offer different trade-offs rather than a single universally superior solution. Future research should focus on predictive scaling, multi-cloud portability, sustainable infrastructure, security automation, and cost-aware orchestration. The reviewed principles can guide the design of AWS-based applications, but production deployment must be validated through workload-specific testing, current service documentation, and organizational requirements.
