    Building and Deploying Static Sites with Hugo

    by Brian Hogan
    Most web sites don’t have data that changes, so why power them with a database and take the performance hit, or worse, inflict it on your visitors? In this talk we’ll explore how to build a web site using Hugo, an open-source tool for building static content sites quickly. In this live demo, you’ll learn how to make a master layout for your pages, how to create content templates to stamp out new pages quickly, how to use Markdown to build content, and how to get all the other pieces a static site needs. Then you'll see how to deploy the site we made to production using containers. After the talk, you’ll be able to build and deploy static web sites quickly with minimal tooling.

    Integrating Machine Learning Capabilities into your team

    by Cameron Vetter
    Machine Learning is here today and is quickly becoming an expected skill of development teams. As a technical leader on your team, you need to not only help your team learn how to do machine learning, but also select the right tools, integrate the tools into your tool chain, and understand how to deploy and version machine learning models. This talk answers these questions using the Microsoft stack as an example. We will walk through my approach to integrating Machine Learning into a team. The topics covered include: • Where to start, while minimizing investment and risk. • The spectrum of tools from off the shelf to handcrafted. • Packaging and deploying your model. • Integrating your model into your system. • Other considerations and risks. You'll leave with my perspective on how to introduce a team to machine learning and how I recommend integrating machine learning into your software development toolkit. TARGET AUDIENCE: Senior Developers, Architects, Technical Leaders

    Developing Great Web APIs Architectures with ASP.NET Core 2.2

    by Chris Woodruff

    You know you have to have a great experience when you develop your apps, right? The greatest experience for your user's centers around their data. That’s why developing a great set of Web APIs is so important. Using ASP.NET Core Web API is a modern cross-platform framework for the modern web. ASP.NET Core Web API can be run on Windows and Linux using all the modern web servers. The secret to it all is knowing how to architect your Web APIs for the best experience.

    Using the architecture in this talk allows your APIs specifically to work better due to:

    • Allowing a clear decoupling of the API endpoints, Data Access (Synthetic or Production) and finally the Data Domain classes.
    • The API Endpoints (Controllers) have no knowledge or responsibility of Data Domain and behind it Data Access.
    • Because of the decoupling and separation of responsibilities testing can be done easily and without issues.
    • Data Access segments of the architecture can easily be switched out without impacting the Domain or API Endpoints.

    By using this architecture not only does the development story become easier but your end users get a much more stable API set to consume. The talk will explain and get you started on using these concepts with your ASP.NET Core 2.2 Web API solutions.

    Kubernetes For Mere Mortals

    by Dave Strebel

    At first sight Kubernetes can seem daunting for most users, as it has many abstractions. Knowing where to start with Kubernetes is half the battle and focusing on learning the core concepts can ease the knowledge gap.

    In this talk we will go from :

    1. Running a Microservice based application on your computer.
    2. Building container images for each service of the Microservice application.
    3. Introduction to Kubernetes. Deploying a Microservice based application into a Kubernetes Managed Cluster.

    The gradual build up provides the depth required for a mere mortal being able to grasp the simplicity of Kubernetes. Yes, Kubernetes is not so complex when you start with the core concepts and understand the abstractions it provides to the end-user.

    Empowering Developers Through Templates and Packages

    by Erik Dahl
    Many teams are trying to peel parts of their monolithic applications into smaller chunks that can stand on their own and even be deployed independently of other applications (microservices, anyone??). This talk will describe the benefit that creating starters, templates, and packages can have on teams doing this kind of work -- or even simply starting more than one new application. The concrete examples will be shown using .NET Core, but these concepts can apply to any language and team that is trying to break down monoliths. Packages and templates can encapsulate your opinions and make them sharable and updatable much better than saying "copy / paste these pieces from another project". Demonstrated in this talk will be an ASP.NET Core Web API template that includes bearer token authentication, error handling / logging, and Swagger, as well as an ASP.NET Core Web MVC project that includes standard npm packages, OpenId/OAuth2 setup for authentication, and logging. We'll spend most of our time looking at the mechanics of the templates - the templates themselves, publishing as Nuget packages, and using the CLI to instantiate projects.

    I Don't Care About Security (And Neither Should You)

    by Joel Lord
    Remember when setting up a login page was easy? It seems like nowadays it can take weeks to start a project--creating a signup form, a login form, a password recovery screen, and all the validation in between. And you haven’t even started on security considerations yet. During this presentation, the attendees will be introduced to OpenID Connect and OAuth. They will also learn how to leverage these technologies to create more secure applications. Most importantly, they will learn how to delegate authorization and authentication so they can focus on their real work and forget about all that security stuff.

    Using Async / Await in C# as Designed

    by Keith Voels
    The syntax for Async / Await in C# is straightforward but the under-the-covers mechanics are not. This discussion will provide a high-level understanding of those mechanics so you can be a true wizard with Async / Await in C#. We will start with an example showing the amazing performance gains that can be had using Async / Await. Then discuss Task Based Asynchronous Processing and the under-the-covers mechanisms ExecutionContext and SynchronizationContext to understand their role. We finish with some advanced examples showing the power of the Tasks namespace. This is an intermediate discussion for C# developers who are already using Async/Await.

    Graceful Decomposition

    by Nathan Good

    Once you've made a decision to modernize your Java Enterprise Edition applications, how do you safely decompose your monolith into micro services?

    Many enterprises are undergoing initiatives to modernized their monolithic application into micro services. But the act of decomposition isn't always straight-forward, and decomposing an application incorrectly can cause more problems than it solves. How do you handle common code to prevent rework? How do you get the most benefit out of deployment isolation?

    In this session, I examine several time-tested techniques that can be used to gracefully decompose your monolith into useful micro services. Using good practices, you will get the most out of your new architecture.

    Walk away from this session with techniques and practices that will help you be successful with micro services from monoliths.
