This cross-platform sample app demonstrates real-world social media experiences around photo sharing across iOS, Android and Windows. To ensure maximized code re-use and a rich user experience at the same time, it uses Xamarin as its cross-platform frontend framework. In the backend, it leverages several advanced Azure Services based on Azure App Services, Azure Functions and Azure Cosmos DB.

This is a fork from the official Appsample-Photosharing project from Microsoft, that was only targeting the Universal Windows Platform (UWP) and was based on a very simple backend architecture. We broadened its potential user base by adding an iOS and Android project and modernized the backendend to enable global scaling, high availablility and advanced workloads.

Xamarin: Take existing UWP code cross-platform to iOS, Android and Windows

COSMOS DB: Provide global scale delivering data with low latency anywhere in the world

Azure CDN: Edge caching of images for fast download

Cognitive Servives: Auto-tagging and description of photos to power search and auto-suggestion

Azure Functions: Manage tagging and updating of metadata in the backend database

Traffic Manager: Route client requests to the nearest Web API endpoint

Azure Key Vault: Manage and store certificates for secure data transfer
