Serverless computing with Microsoft Azure

Editor's Notes

• #5: Talking points: (New) Note to speaker: no extra clicks needed, all visuals will fly in on their own at page load time. Before Cloud (or even now), let’s say you run a successful business and you try to build business apps, you have two options. You can either build on premises or co-location. You will go and buy servers and infrastructure to run your business applications. With that came many questions when you build and manage your own server. From what servers to buy, how to provision my new server, what do I do if there is hardware failure, to how to deploy my code and patch my servers, there are simply too many things to consider. It can be overwhelming when you manage your own physical servers.  
• #6: points: (New) Note to speaker: no extra clicks needed Well, a much cleaner picture, isn’t it? A few years later, there is this thing called “IaaS”. The idea is, you don’t need to buy or build your own servers, use our infrastructure service, aka IaaS. With that, you don’t have to worry about provisioning your servers, or securing the physical location of your server farm. Many questions go away. But, there is but… you still need to think about which IOS to use, how to patch the server, in addition to managing your business apps. Can those tedious tasks be taken care of as well?
• #7: Talking points: (New) Yes. We have this service called Platform as a Service, PaaS. What is great about it is, VM patching, IOS selection, back up and code deployment are all built into PaaS platform for you. Isn’t that great? Now only four questions remain, How many servers do I need? What is the right size of server for my biz? S1, P3? How can I increase server utilization? More importantly, how I scale my app? Let’s see how everything works together so far --- transition into the IaaS & PaaS chart. 
• #8: In today’s cloud enabled world, businesses are solving for maximum efficiency and faster time to market, while reducing IT spend. Over the years we have seen businesses evolve from spinning VMs to leveraging the benefits of PaaS cloud such as managed infrastructure, scalability, high availability and cost.
• #9: Today, more businesses are trying to solve for what is core to their business focus – delivering services faster to their customers, while reducing IT spend significantly. The answer comes in the form of Serverless application platform. In industry terms, when you hear someone say “Serverless” more often than not they are talking about Serveless Compute services which form the glue that enable developers to build their apps faster leveraging a variety of other PaaS services. Serverless lets businesses maximize their benefits of the PaaS cloud by offering a fully managed infrastructure, with no servers to manage, provision and patch; hence reducing management overhead significantly. The event triggered programming model, allows for continuous auto-scaling and micro billing capabilities. Event-triggered compute and event-triggered scaling allows businesses to pay only for the compute power that was used, depending on the size of the workload.
• #10: Talking points: (New) What do we go from here? Introducing Serverless, an event-driven process, which will grow and scale on demand. The only remaining question now becomes: How I architect my app to become Serverless? Pretty neat, right? It all sounds great, naturally, you may ask, how does Serverless fit into the picture?
• #12: 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 Setup time, provisioning is long & costly
• #13: “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”
• #15: Azure Functions is a Serverless, event driven compute that allows you to: * Make composing Cloud Apps insanely easy Develop Functions in C#, Node.js, F#, Python, PHP, Batch and more Focus on Business Logic, not infra problems * Easily schedule event-driven tasks across services * Expose Functions as HTTP API endpoints * Scale Functions based on customer demand * Easily integrate with Logic Apps
• #17: This is the whole (top level) Dev Ops story where Dev build wounderful apps, using CI they mange their code, builds, and releases. Connecting to a repository, they can deploy to Azure Websites, build in the cloud, deploy to a slot to test and validate, swap into production, deployed across the globe as needed, monitor and get feedback, on which devs can make updates. Rinse and repeat
• #25: Most folks that get started with Azure Functions first start from the Azure Portal where we have a variety of features to help you get started quickly.
