Cloud Architecture Decisions for Scalable Applications : A Practical Guide to AWS Deployment Models

In today’s rapidly evolving digital landscape, cloud computing has become the foundation of scalable, resilient, and high-performing applications. Yet one of the most critical challenges for architects, developers, and technology leaders is selecting the deployment model that best aligns with their technical requirements, operational capabilities, and business goals. Cloud Architecture Decisions for Scalable Applications offers a practical, hands-on exploration of four widely adopted AWS deployment models—Amazon EC2, Amazon ECS, Amazon EKS, and AWS Elastic Beanstalk. Using a real-world Spring Boot–based BookStore application as a consistent reference architecture, the book demonstrates how each deployment approach influences scalability, availability, performance, operational complexity, maintainability, and cost efficiency. Moving beyond theoretical discussions, the authors present detailed architecture diagrams, implementation workflows, deployment strategies, configuration guidelines, and performance observations drawn from practical implementation. Readers gain valuable insights into cloud-native design principles, containerization, Kubernetes orchestration, load balancing, monitoring, security best practices, and managed database integration using Amazon RDS. Whether you are a student building foundational cloud skills, a software engineer modernizing applications, a DevOps professional managing cloud infrastructure, or an architect making strategic technology decisions, this book provides a structured framework for evaluating AWS deployment options and selecting the right architecture for scalable, reliable, and future-ready applications.
