Abstract

Updating and restructuring outdated systems is essential for organizations seeking to harness the scalability, adaptability, and robustness offered by cloud-native architectures. Legacy systems can obstruct innovation because of their rigid structure, expensive maintenance, and inability to scale effectively. Amazon Web Services (AWS) provides a comprehensive suite of advanced services that enable the efficient transformation of such systems into modern, cloud-native solutions. This paper explores strategies and best practices for utilizing AWS advanced services, such as AWS Lambda, Amazon Elastic Container Service (ECS), Amazon Elastic Kebernetes Service (EKS), and Amazon Relational Database Service (RDS), to achieve seamless modernization. It delves into serverless computing, containerization, database migration, and microservices architecture as pivotal approaches to refactoring legacy systems. AWS Step Functions and Code Pipeline are also highlighted for automating workflows and continuous integration/deployment (CI/CD) processes, enhancing development agility. Reducing technical debt is a key focus, as modernization simplifies codebases, eliminates redundant processes, and improves maintainability. Operational efficiency is enhanced by leveraging managed services like AWS CloudWatch and AWS Systems Manager, which provide real-time monitoring and automated management, reducing downtime and optimizing resource utilization. Furthermore, this paper emphasizes the role of modernization in driving innovation. By transitioning to microservices, organizations can achieve faster deployment cycles, greater scalability, and the ability to adopt emerging technologies like artificial intelligence and machine learning with services such as Amazon SageMaker and AWS Rekognition. Through case studies and real-world applications, the findings underscore the transformative impact of AWS-powered modernization in enabling businesses to remain competitive, agile, and future-ready in an ever-evolving technological landscape. This paper provides actionable insights for leveraging AWS to achieve successful and sustainable legacy system transformation.
