eXtreme Serverless Azure: Data, Compute, Realtime - in Action!

Whaaat? No servers? Well, yes. Serverless is all the hype these days. Let's try to sort out some of the real strenghts of Serverless and see where Serverless & PaaS build a set of highly productive weapons in your Cloud arsenal. Join Christian Weyer from Thinktecture while he discusses Azure Functions, Storage, CosmosDB and SignalR Service in a holistic scenario - all by building an end-to-end solution that should 'just work' by the end of this session: creating a scalable real-time application in almost no time - really? Aaand action!

3. 3 § Microservices, Nanoservices § Serverless in Azure § Azure Functions § Azure Cosmos DB § Azure SignalR Service eXtreme Serverless Azure Data, Compute, Realtime - in Action! Topics
4. 4 How ‘large’ is ‘small’? Microservices Data, Compute, Realtime - in Action! eXtreme Serverless Azure
5. 5 § Modern business applications architectures: we strive for isolating functional services § Choice of technology, use best communication means § Microservice: unit of independent deployment for a business domain-specific service § Nanoservice: like Microservice, but more focused & lightweight; can be replaced easier § Functions as the mental model § Make things easier, get productive eXtreme Serverless Azure Data, Compute, Realtime - in Action! Microservices – or rather: Nanoservices !

12. 12 Azure Functions Serverless Code / Compute Data, Compute, Realtime - in Action! eXtreme Serverless Azure
13. 13 § Azure Functions is code being triggered by an event § Focused code + events § Basic principles enable powerful use cases § Events § Triggers § Bindings § Two ways of operation § Cost-optimized, automatic scale (aka Consumption Plan) § Always-on § V2 Runtime built on .NET Core § Available for e.g. self-hosting Data, Compute, Realtime - in Action! Azure Functions: Functions-as-a-Service eXtreme Serverless Azure
14. 14 § Incoming event triggers function § Input bindings enable easy access to data from various data sources § Output bindings offer easy access to outbound data sinks Data, Compute, Realtime - in Action! Triggers & Bindings eXtreme Serverless Azure Your code logic Runtime Azure Function HTTP Trigger Storage Input Binding Push Notification Output Binding Database Output Binding Email Output Binding Example
15. 15 Data, Compute, Realtime - in Action! Triggers & Bindings in Code eXtreme Serverless Azure
16. 16 § In portal, via CLI, or in IDE § Visual Studio wizards for pre-compiled Functions § Local tooling & runtime available § Debugging locally or remote § Multiple language bindings supported § C# & C# Script (CSX) § F# § JavaScript, TypeScript (node.js) § Java (preview) Data, Compute, Realtime - in Action! Developing Functions eXtreme Serverless Azure

18. 18 Azure Cosmos DB Serverless Database Data, Compute, Realtime - in Action! eXtreme Serverless Azure
19. 19 § Globally distributed, elastically scalable § Fully managed by Azure § But not yet fully automatically scaling § Pricing not (yet?) suitable for low-entry projects § Multi-model database § Key-value, document, graph ➔ NoSQL § Multiple APIs § DocumentDB, with SQL & JS APIs § MongoDB API § Cassandra API § Table Storage API § Graph Database with Gremlin API Data, Compute, Realtime - in Action! Cosmos DB: A Database with Many Faces eXtreme Serverless Azure
20. 20 § Building event-driven architectures with Cosmos DB § Listening to Azure Cosmos DB collection for any changes § Inserts, updates, soft-deletes § Subscribe to collection changes § Can be used as a trigger for Azure Functions Data, Compute, Realtime - in Action! Cosmos DB Change Feed eXtreme Serverless Azure
21. 21 Serverless Realtime Azure SignalR Service Data, Compute, Realtime - in Action! eXtreme Serverless Azure
22. 22 § Realtime is a wanted feature nowadays § Dashboards and monitoring apps § Collaborative apps § Apps that require notifications § ASP.NET Core SignalR provides programming model for bi-directional ‘method invocation’ – via WebSockets, SSE or Long Polling § Wanted: “SignalR messaging & scale-out”-as-a-Service ➔ Azure SignalR Service § Azure Functions bindings available (in preview) eXtreme Serverless Azure Data, Compute, Realtime - in Action! Azure SignalR Service
