Project 3: Building a Serverless Application on Azure

Project 3 Architecture

This project demonstrates the development of a scalable and cost-effective serverless application using Azure Functions, Azure Logic Apps, Azure Event Grid, and Azure Cosmos DB. The application is designed to process incoming data, perform transformations, and store the results in a NoSQL database.

Challenges

  • Handling high volumes of incoming data with varying loads.
  • Ensuring data consistency and reliability in a distributed environment.
  • Minimizing operational overhead and costs.
  • Implementing a flexible and scalable architecture.

Solution

Azure Functions were used to handle data ingestion and processing. Azure Logic Apps orchestrated the workflow, integrating various services. Azure Event Grid enabled event-driven architecture, triggering actions based on specific events. Azure Cosmos DB provided a scalable and globally distributed NoSQL database for storing the processed data.

Technologies Used

  • Azure Functions
  • Azure Logic Apps
  • Azure Event Grid
  • Azure Cosmos DB

                                            C --> D(Azure Cosmos DB)

Outcome

The serverless application successfully handled varying workloads, scaling automatically based on demand. The use of Azure Functions and Logic Apps significantly reduced operational overhead and costs. The application demonstrated high availability and reliability, leveraging the strengths of Azure's serverless platform.
