Christos Matskas discusses Azure Functions, a serverless computing service that allows developers to run code without managing infrastructure. Azure Functions provides benefits like reduced DevOps workload and faster time to market by managing applications rather than servers. It uses a variety of triggers and bindings to connect events to code execution and integrates with tools for local development, monitoring, and deployment.

- 9. Running Functions Pay only for what you use! Metering is per execution and per GB Second. Your own dedicated cloud environment with network isolation for apps, higher scale, and the ability to connect securely to local vNets. All the advantages of Functions with the SLA and ‘always on’ features of an App Service Plan.
- 10. Embracing new scenarios Totally portable Run on Functions on Linux with our containers, BYOC, Use Kubernetes or Service Fabric Leverage cloud innovations in on-premises infrastructure. Azure Stack brings the power of Azure to your own data centers. Run your Azure Functions on your local server (without the rest of Azure)

Editor's Notes
- “What is serverless?”
- Abstraction of servers, infrastructure and configuration of operating system Event-driven scale Sub-second billing Stateless Serverless compute is a fully managed service. Some refer to it as Functions as a Service OS and Framework patching is performed for you There is zero administrative tasks and no need to manage any infrastructure You just deploy your code (function) and it runs Your code runs within seconds and for very short period of time Serverless compute scales quickly (almost instantly) and vastly Automatically scales within seconds No scale configuration is required (there is no way to configure scale or limits) Scales to match any given workload. Scales from zero to handle tens of thousands concurrent functions invocations within seconds Pay only for the time your code is running Serverless compute reacts to events React, in near real-time, to events and triggers Triggered by virtually any event from Azure service or 3rd party services
- “Pinnacle of PaaS compute” Not just hardware “servers”, but software servers are also managed for you Focus on business logic, not solving technical problems not core to business Lower effort to get started makes it easier to experiment (bots, etc.) Benefits of “Serverless”
- Azure’s serverless picture
- First, a simple event hub JS function (just trigger) Then, a good example of a C# function with a trigger and input/output bindings
