Advanced Serverless Computing in Azure: not another "Hello serverless World"!
Download as PPTX, PDF1 like129 views
The document discusses advanced serverless computing in Azure, focusing on Azure Functions and their various features such as scaling, language options, and triggers. It compares functions 1.0 and 2.0, introduces durable functions for stateful workflows, and highlights tools like Azure Logic Apps and Azure Event Grid for integrating enterprise processes and event-driven communication. The document also includes details about pricing models and emphasizes the importance of automation and rich monitoring capabilities.

Advanced Serverless Computing in Azure: not another "Hello serverless World"!
- 1. Advanced Serverless Computing in Azure: not another "Hello serverless World"! Lorenzo Barbieri Cloud Solutions Architect lorenzo.barbieri@microsoft.com
- 2. Our sponsors and friends
- 5. Serverless application platform components
- 8. Scaling happens at the Function App level
- 10. Functions runtime 1.0 and 2.0 key differences Functions 1.0 Functions 2.0 .NET Support .NET Framework 4.7.1 .NET Core 2.2 Assembly isolation No Yes Bindings versions Runtime versions User controlled Language options Limitations in languages and versions Languages are external to the host Node.js version Node.js 6 only Node.js 8 & 10 + future versions Node.js native modules Not supported Supported HTTP triggers HTTP and specialized Webhooks HTTP (supports Webhooks) Language Runtime Multiple languages per function app Single language per function app Functions Proxies GA GA OpenAPI definition Preview 3rd party or through API Management Observability Application Insights/WebJobs dashboard App Insights

- 14. Do you remember «Micro-billing»? Consumption Plan Pay as you go Execution time: €0,000014/GB-s Total Executions: €0.169 x 1M execution Free grant (per month) 400,000 GB-s 1M executions Unlimited scalability! *Network and storage account charged separately as applicable, prices can change over time App Service Plan Calls are «capped» by the App Service Plan VNET, unlimited duration, VS live debug $
- 15. Durable Functions Stateful Services and Workflows (code)
- 17. long-running orchestrations single function maintaining local state
- 18. // calls functions in sequence public static async Task<object> Run(DurableOrchestrationContext ctx) { try { var x = await ctx.CallActivityAsync("F1"); var y = await ctx.CallActivityAsync("F2", x); return await ctx.CallActivityAsync("F3", y); } catch (Exception) { // global error handling/compensation goes here } } Orchestrator Function Activity Functions What It Looks Like
- 19. Orchestrator Function Activity Function var outputs = new List<string>(); outputs.Add(await context.CallActivityAsync<string>("SayHello", "Durable!")); return outputs; ? Orchestration with durable functions PG-NR FOR EDUCATION PURPOSES ONLY, NEVER DO A “HELLO WORLD” WITH DURABLE FUNCTIONS
- 20. Azure Logic Apps Enterprise Integration and Workflows (designer)
- 21. LogicApps Automate business processes in the cloud
- 23. Both allow implementing advanced workflow patterns. C# and JavaScript Visual Designer ~20 Bindings 200+ Connectors Portable runtime Runs only on Azure Monitoring based on App Insights and APIs Rich monitoring and management tools Consumption with Free Tier, App Service Plan Consumption (you pay every task) Stateful Replays Queued Dependency Graph Durable Functions vs Logic Apps
- 24. Azure Event Grid
- 25. Eventing in the cloud Event grid
- 26. Event Grid guiding principles Always available Near real-time event delivery At least once delivery Dynamic scale Platform agnostic (WebHook) Language agnostic (HTTP protocol) Fan-out (multiple subscribers)
- 27. Event driven communication = decoupled services

- #24: At the end of the day, both durable functions and logic apps have their benefits. From speaking with several customers, we’ve realized that which one you choose is simply a matter of individual preference. Logic Apps is a big product itself with several features of its own so I wont dive into too much detail about that here but feel free to stop by our booth to see some demoes and get more information. Logic Apps can run Durable Functions! You can hook them into your Logic Apps workflows.
