Leveraging serverless architecture for scalable email append and data aggregation

Serverless computing has revolutionized the design and deployment of scalable, event-driven applications by abstracting infrastructure management and offering granular billing models. This review explores the application of serverless architecture in the specific context of email append and data aggregation systems, highlighting how Function-as-a-Service (FaaS) platforms facilitate efficient, cost-effective, and scalable workflows. By means of a comprehensive study of the architectural patterns, experimental studies, and benchmarking evidence, we identify the strengths and weaknesses of serverless technologies. We consider major challenges, including cold starts, state management, orchestration, and third-party APIs. In addition, we look at emerging solutions and hybrid models. The survey concludes with a research and development roadmap, aimed at tackling performance bottlenecks, improving developer tooling, and developing AI-driven orchestration mechanisms.
