Serverless Boost For Your Next Startup

This is a presentation I used during a couple of the Google Developer Groups DevFest events during December 2019.

2. Serverless architectures refer to applications that significantly depend on third-party services (knows as Backend as a Service or "BaaS") or on custom code that's run in ephemeral containers (Function as a Service or "FaaS")
3. • The real dream of PAAS • No Infrastructure, No Containers (seriously?) • Scalable as hell! • Granular Billing (GB/s, GHz-Second) • No commitment, no hardware provisioning (c’mon?)
4. • Containers are the new VMs! • Server Patching > Container Image Batching • Container Orchestration is hard. • What if I have my dependencies though?
5. • You can have a fleet of EC2 instances, running containers, orchestrating and still worry about infrastructure. • You can have dozens of functions tightly coupled and delivered as a behemoth.
6. • Javascript, C#, C# Script, Python, PHP, Batch, Powershell • Timer-based processing • SaaS Event Processing • Full Serverless Architecture • Real-Time Stream Processing • Real-Time Bot Messaging • Serverless mobile back-ends
9. Creating our first “Hello World” function!
14. • Anonymous • Function Key • Host Key
20. • A “Run” file that containing the function code • A “Function” file containing all service and trigger bindings and parameters • A “Project” file containing project assembly and NuGet package references • App Service settings, such as connection strings and API keys
21. V1 Only on Windows npm install -g azure-functions-core-tools V2 with .NET Core on all platforms npm install -g azure-functions-core-tools@core Initialize your first function func init MyFunctionProj
22. Precompiled functions with C# and Visual Studio
27. • local.settings.json will have all your local settings on the dev machine. • C# can also be read in your code as environment variables. Use System.Environment.GetEnvironmentVariable or ConfigurationManager.AppSettings. • In JavaScript, use process.env
28. • Extend the existing Azure App Service platform • Go with “Consumption Plan” and be pure Serverless • Deploy Functions Runtime on an on-prem location in your Private Cloud. • Deploy Functions to Google Cloud, AWS, and more.
29. • Scale Controller : event-driven scaling through KEDA • Runtime Controller : functions runtime in a Docker container
30. Documentation • https://goo.gl/TqGtMr Azure Functions Runtime (Run on-prem) • https://goo.gl/hV7KgJ Documentation for the host.json file • https://goo.gl/W6kcV7 More CLI commands to run functions locally • https://goo.gl/PSkqet Functions on Kubernetes • https://drn.fyi/2ppbVxN
