Abstract:
This research analyzes AWS AppSync's effectiveness in enabling scalable, real-time communication between web applications. It highlights the benefits of serverless models in resource efficiency and cost. A comparison between AWS AppSync and WebSockets via API Gateway i s performed, with load testing to assess performance. Despite some limitations like GraphQL constraints and connection caps, AppSync proves efficient for complex, interactive applications. The study outlines key selection criteria, including scalability, integration, security, and cost, concluding that the choice depends on the application's specific architecture and needs.
