클라우드 기반 앱 현대화를 위한 5가지 체크리스트 - 윤석찬 :: AWS 현대적 애플리케이션 개발
Download as PPTX, PDF1 like405 views
The document outlines a checklist for modernizing cloud-based applications through five key practices: structuring applications as microservices, utilizing serverless technologies, modeling applications and infrastructure with code, implementing continuous integration and deployment (CI/CD), and monitoring application behavior. It emphasizes the benefits of these practices in terms of agility, innovation, and efficiency while providing a framework for developers to enhance their cloud capabilities. Additionally, it offers resources for further education and training to bolster cloud technology skills.
