Serverless Architecture And Big Data

Definition and Core Concepts

Serverless Architecture refers to a cloud computing model where developers build and run applications without managing the underlying infrastructure. Instead of provisioning servers, developers rely on cloud providers to handle resource allocation, scaling, and maintenance. This model is event-driven, meaning resources are allocated only when specific events trigger them, ensuring optimal efficiency.

Big Data, on the other hand, encompasses the collection, storage, and analysis of massive datasets that are too complex for traditional data processing methods. It is characterized by the "3 Vs": Volume (large amounts of data), Velocity (speed of data generation and processing), and Variety (diverse data types). Big Data technologies enable organizations to extract valuable insights from structured, semi-structured, and unstructured data.

When combined, Serverless Architecture and Big Data create a powerful framework for processing and analyzing data at scale without the need for extensive infrastructure management.
