Cloud Architecture Design Principles Designing for the cloud requires a shift in thinking from traditional on-premises architecture. Cloud architecture must be scalable, resilient, secure, and cost-efficient — all while supporting the goals of the business. This topic explores the core design principles that cloud architects must follow to build modern, high-performing cloud environments. 1. Design for Scalability Cloud systems should scale up or down automatically to meet fluctuating demand. Horizontal scaling (scale-out): Add more instances (e.g., web servers, containers). Vertical scaling (scale-up): Increase CPU/RAM on an existing instance. Use of autoscaling groups, load balancers, and container orchestration (e.g., Kubernetes) are vital tools. 2. Design for High Availability and Resilience Systems should continue to function during outages or unexpected failures. Distribute workloads across multiple availability zones or regions. Use redundancy , fa...
