Project Overview:

Welcome to the Trivia Game Application!

Serverless Architecture

Introduction:

The Trivia Game Application is a feature-rich platform designed to provide users with a captivating trivia experience. This project addresses various aspects of user engagement, from authentication and profile management to in-game experiences and virtual assistance.

Distinguished by its cutting-edge architecture, the Trivia Game Application leverages microservices, Multi-cloud integration, and serverless computing to elevate its performance and scalability. Users can expect a high-quality, resilient, and adaptable trivia platform that thrives on the latest advancements in technology.

By incorporating cloud services, AI, and modern development practices, this project sets a standard for interactive and feature-packed applications.

High-Level Overview:

The Trivia Game Application follows a modular architecture, leveraging microservices for individual features. Key design decisions include:

Serverless architecture using AWS Lambda and GCP Cloud Functions.
Cloud-native data storage with GCP Firestore and AWS DynamoDB.
Docker containerization for microservices, hosted on AWS ECR.
Integration of AI services for enhanced team management.

Cloud Services Integration:

The Trivia Game Application makes extensive use of cloud services from AWS and GCP:

AWS Services:

Cloud Service	Usage in Project
AWS Cognito	First level authentication in User Authentication feature. Handles user credentials, access tokens, and AWS credentials.
Amazon DynamoDB	Used in User Profile Management (storing user profile information and game results), Leaderboards (storing game results data), and Automated Question Tagging (storing tagged questions).
Amazon S3	Used in User Profile Management (storing user profile pictures), Leaderboards (loading and processing game results data), and Trivia Content Management (storing game data for analysis and visualization).
AWS Lambda Functions	Utilized in multiple features, including User Authentication (processing authentication logic), User Profile Management (handling various functionalities), Leaderboards (implementing micro ETL for game results), Team Management (implementing various functions), Virtual Assistance (handling chatbot features), Trivia Content Management (implementing various functions), Automated Question Tagging (tagging questions), and In-Game Experience (processing game logic).
AWS API Gateway	Used for exposing Lambda Functions as REST APIs in multiple features, enabling communication with the frontend.
AWS Athena	Used in Leaderboards and Trivia Content Management for data analysis and querying.
AWS QuickSight	Used in Leaderboards for visualizing and creating dashboards based on game metrics and performance data.
AWS Secret Manager	Used for securely storing sensitive secrets, such as API keys or private keys, in multiple features.
Amazon Lex	Used in Virtual Assistance for building a chatbot with features like user navigation assistance, team score retrieval, and leaderboard retrieval.

GCP Services:

Cloud Service	Usage in Project
GCP Cloud Functions	Second level authentication in User Authentication feature. Used to handle security questions and answers. Also used in Trivia Game Lobby for fetching specific data of quiz from the database.
GCP Firestore	Used in multiple features, including User Authentication (storing security questions and answers), User Profile Management (storing user information), Trivia Game Lobby (storing games and questions), Team Management (as a database for team-related data), and Automated Question Tagging (storing tagged questions).
Google Cloud Natural Language API	Used in Automated Question Tagging for its NLP capabilities in automatically tagging newly added questions.
