Building production-ready systems requires a blend of software architecture, infrastructure, and DevOps best practices. In this session, I explore the foundational principles and key design considerations (e.g., security, scalability, availability, observability, and cost optimization), that enable resilient cloud-native applications. Through real-world case studies, drawn from my personal experience, I demonstrate how to transition from traditional deployments to highly scalable, fault-tolerant systems using AWS services and modern DevOps practices. Whether you're an architect, engineer, or technology leader, this talk provides strategies and insights to elevate your system’s reliability and accelerate digital transformation.
