MIGRATING MONOLITHS TO SERVERLESS SAAS: A CLOUD MICROSERVICES APPROACH ON AWS

Abstract

This article explores the strategic migration of monolithic SaaS applications to serverless architectures using cloud microservices on AWS. We examine the advantages of this transition, including improved scalability, cost-effectiveness, and enhanced development agility. The article outlines a comprehensive migration strategy, detailing the process of decomposing monoliths into microservices and leveraging AWS Lambda as the core serverless platform. We discuss the integration of various AWS services, including CloudWatch for monitoring and Aurora Serverless for database optimization. The implementation of event-driven architectures and the adoption of DevOps practices with CI/CD pipelines are also addressed. The article highlights the importance of data security in serverless environments and explores the role of business intelligence in driving data-informed decision-making. While acknowledging the challenges, such as initial refactoring efforts and the learning curve associated with new technologies, we present evidence of significant benefits in terms of cost savings, scalability improvements, and accelerated development cycles. This article provides valuable insights for SaaS providers considering the transition to serverless architectures, offering a practical roadmap for implementation and optimization.
