Deltatre’s OTT platform for sport events Cloud based + hybrid scenario fully hosted in Microsoft Azure as PaaS 11 end-user platforms same UI/UX Full coverage from venues to end-users Unified management subscriptions, payments, analytics, CRM, marketing

Global architecture overview

Cloud API Microservices architecture App Services Azure Functions for frontend & REST APIs Azure Functions serverless back-office API and monitoring services; frontend for remote configuration

Data storage and distribution Cosmos DB full managed service Built-in key features global scale by design automatic replica management transparent scaling high throughput high availability low latency Redis Cache for data access optimization Traffic Manager for geographic routing CDN (Akamai) for geographic distribution

Azure Search PowerBI dashboard & analytics Used for indexing, full-text and geo-localized search, full integration with Cosmos DB and other built-in features (multi-language, filters, sorting, paging, monitoring, etc.). PowerBI dashboard & analytics monitor, tune and optimize the search service to analyze what users search for and optimize queries, indexes, etc.

Monitoring and logging Application Insights different dashboards for different needs

Custom scaling management Sport events  very narrow load peaks Azure Autoscale does NOT work well in this scenario Hybrid approach Manual scale-up Automatic scale-out

Data and video ingestion cloud endpoint to push data/metadata about matches, scores, statistics, ingested using our on-premises data system Forge Video from venues to cloud, encoded with Amazon Elemental and ingested in Azure Media Services for processing and distribution, leveraging our on-premises Diva video platform ExpressRoute used to optimize connections between venues and Azure datacenters

3rd parties integration User API unified abstraction API to seamlessly use services from 3rd party providers to manage users, payments, engagement and content protection

3rd parties integration Geographic Content Protection MaxMind geolocation (country level) + custom development for user entitlement (subscription-level rights) and CDN protection (token-based) Monetization and “universal” payments MPP Global Solutions platform + Roku/iTunes SDKs Customer identity Gigya platform for Customer Identity Management CRM, marketing and users engagement Two Circles services to understand and engage with users Urban AirShip for push notifications, in-app messages

End-user TennisTV apps Same UI/UX across all 11 platforms Enhanced DIVA Video Player experience (video + overlays) Web React-based SPA, HTML5/CSS/JS iOS, Android, Apple TV, Roku, Chromecast, AirPlay native applications (Swift/Java/BrightScript) Smart TVs, Xbox, PS4, Amazon Fire TV HTML/JS open-source TV Application Layer (TAL) framework by BBC http://bbc.github.io/tal/

Teams & Timing January 2016  Development start December 2016  Deploy in production Development team 13 people (1 DevOps, 3 Backend, 5 Frontend, 2 Tech Leads, 1 Solution Architect, 1 PM) Running/management team 3 people (1 Backend, 1 Frontend, 1 Tech Lead)

Conclusions First project full PaaS What’s next? hybrid support, microservices, peak loads, fault tolerance design cultural mindset change required  team change-resilience What’s next? search improvement recommendation engine (based on Cognitive Services) per-user customized content full cloud with new Forge/Diva platforms new OTT platforms
