Serverless Architecture And AI

Definition and Core Concepts

Serverless Architecture refers to a cloud computing model where developers build and run applications without managing the underlying infrastructure. Cloud providers like AWS, Azure, and Google Cloud handle server provisioning, scaling, and maintenance, allowing developers to focus solely on application logic. In this model, resources are allocated dynamically, and users are charged based on actual usage rather than pre-allocated capacity.

Artificial Intelligence (AI), on the other hand, involves the simulation of human intelligence in machines. It encompasses a wide range of technologies, including machine learning (ML), natural language processing (NLP), and computer vision, enabling systems to learn, reason, and make decisions.

When combined, Serverless Architecture and AI create a powerful synergy. Serverless platforms provide the scalability and cost-efficiency needed to deploy AI models, while AI enhances serverless applications with intelligent features like real-time analytics, personalized recommendations, and automated workflows.
