Description

Introduction of Cosmos DB &Azure Functions

This course explores how to integrate this to build real-time data solutions. Participants will learn how to use Cosmos DB as the backend data store while leveraging Azure Functions to process and react to events in real-time. The course covers setting up event-driven architectures, working with triggers, and managing scalable solutions for real-time data processing.

Prerequisites

• Basic Knowledge of Azure: Familiarity with Azure services like Cosmos DB and Azure Functions.
• Experience with .NET or JavaScript: Basic programming knowledge in C#, JavaScript, or other relevant languages used with Azure Functions.
• Understanding of NoSQL Databases: Basic knowledge of Cosmos DB or NoSQL databases.
• Familiarity with Event-Driven Architectures: Experience with event-driven or microservices architectures is beneficial.
