📘 Cloud Native Architecture — Definition

Cloud Native Architecture is an approach to designing, building, and running applications that fully leverage cloud computing capabilities such as scalability, elasticity, automation, and resilience.

Cloud native is:

An architecture style that enables organizations to build and run scalable, flexible applications in dynamic environments (public, private, hybrid cloud), using technologies like microservices, containers, serverless, and DevSecOps.

🔑 Key Characteristics

• Microservices-based design (loosely coupled services)
• Containerization (e.g., Docker, Kubernetes)
• Event-driven architecture
• Serverless computing
• DevSecOps & automation
• Elastic scalability & resilience
• API-first and cloud-first design

🎯 Core Objective

To accelerate innovation, improve agility, and enable continuous delivery while reducing operational overhead.
