The evolution from monolithic architecture to cloud-native applications marks a significant shift in software design, driven by the need for flexibility, scalability, and faster deployment. Initially, monolithic systems posed challenges in maintenance and distribution, leading to the adoption of the three-tier MVC architecture, which improved code maintainability. However, the demand for rapid market delivery and integration of development and operations (DevOps) catalyzed the emergence of cloud-native designs. Governed by the Cloud Native Computing Foundation (CNCF), cloud-native applications utilize a microservices approach, containerization, and horizontal scaling through orchestration tools like Kubernetes, enabling them to adapt to varying workloads efficiently. These applications are distinguished by their infrastructure agnosticism, API-driven architecture, service mesh for communication management, and zero-downtime deployments, all supported by continuous integration and delivery (CI/CD) pipelines. Emphasizing policy-driven resource provisioning and service discovery, cloud-native applications facilitate seamless scalability and maintenance. The transition to cloud-native requires not only technical re-architecting of applications but also a cultural shift within organizations, focusing on modern technologies and processes to fully leverage the benefits of cloud-native strategies.
