Cloud-Native Development: Review of Best Practices and Frameworks for Scalable and Resilient Web Applications

Recent innovations in cloud computing have prompted a sea change away from monolithic systems to cloud-native architecture, enablingdevelopers to build adaptable, scalable, and modularapplications. Key technologies such as serverless computing, containerization, and microservices architecture are used in cloud-native development, enhancingoperational efficiency, flexibility, and the deployment speed ofapplicationsin dynamic business environments. While these technologies allow organizationsto build applications with improvedadaptability, scalability and resilience, they also introduce challenges,including managing complex service dependencies, diagnosing failures, optimizingperformance, and ensuring security in highly distributed systems. Moreover, managing stateful services and ensuring data consistency in the cloud environment can be particularly challenging. In this paper,the fundamental principles of cloud-native developmentare explored with focuson resilience, scalability, and elasticity while addressing the challenges faced by developers. Further, best practices like continuous integration and deployment (CI/CD), infrastructure as code (IaC), and security-focused DevSecOps practicesare emphasized. Furthermore, a reviewofessential tools and frameworks, such as Kubernetes, Prometheus, and AWS CloudWatch, that assist in orchestrating, monitoring, and optimizingcloud-native systemsis provided.
