An overview of the Tailwind Traders reference apps for Azure | Azure Friday

>>Hey friends, you know we develop sample applications and release them in open source repositories on GitHub so that you
can learn how to use Azure services and features
from working code. You’re welcome to use
this code at your events, in your blog post, or even to jumpstart
your own professional projects. David Sanchez is here
to give us a tour of the Tailwind Traders Codebase
today on Azure Friday. [MUSIC]>>Hey, I’m Scott Hanselman, and it’s Azure Friday and I’m here
to talk about Tailwind Traders. David Sanchez, how are you?>>Very good and you?>>I’m feeling pretty good.
I love this code base. You and I have worked
together on this and given demos and presentations.>>Exactly.>>Anybody can do that, right?>>Yeah.>>We presented build and things, but they can present
it there user group.>>Exactly. Yeah. They can
use it for their event, blog post videos, or
even into training.>>What’s interesting about it, it’s more complicated
than most demos. There’s a lot of cool stuff going on.>>Yes, and we always maintain
and keep working on this. So we add more documentation to reduce the complexity
of these demos.>>It’s not just a website that
talks to a database, right?>>No.>>It tries to showcase and show
you best practices as well.>>Yes, exactly. We have
a different repos as well. So we will go through
each repos, and each app.>>So how is the structure here? This is the homepage here in GitHub.>>Yes. So right now here I am at This is the main repo. Here we cover basically an introduction
of Tailwind Traders. So Tailwind Traders is
a fictitious retail company store. We developed a set of applications to showcase
the different features and Azure services that you can use to basically modernized
these applications.>>So you got AKS backend. Your websites in ASP.NET. You happen to use React. The other nice thing
about this is that there’s a desktop component as well.>>Yes, and the desktop is based
on.NET Core 3 that is on preview.>>So you really are
keeping it fresh. I think that we do
have a habit that we see samples out there that someone makes it
and they leave it there.>>Yeah, exactly.>>This is always fresh.
Always fun new stuff happening in Tailwind Traders.>>Yeah, we consistently
are updating these repos.>>It also has mobile
applications too.>>Yes, based on summary forms for, that is also in preview. So we are trying to
add the latest bits that we have from the different engineering teams
in order to do these demos.>>Yeah. So let’s give me a tour of the different repositories
and how it works.>>Absolutely. So first of all, we have the different repositories. You said we have
the different technologies that we use in each repo, and we also have demo scripts. These demo scripts will help you to not only deploy the application, but also understand how
to use the application once that you already to deployed
or build it or run it locally. Yeah. For example, we have here
the applications, and for this one we use the rewards application
that is ASP.NET Framework. So it is Web Forms Application
based on.NET Framework. What do you need? What is
the takeaway of this demo script? The different steps that you have to do in order to deploy
it and to use it. As well, we have
some author demo scripts. As I mentioned before, we are also adding more demo scripts
and more documentation. So as part of
the application diagram, here we have the website. As you mentioned, it is
a react based with.NET Core. We connect it to the backend devices that our containers are
running on Kubernetes. So we have as well the, there you go. We have as well the mobile
apps that connect to the backend that is
hosted in the AKS. We have the rewards application
that it is independent. It is basically connected
to a SQL Server Database. We modernize this application
adding Cloud Native Services like, Logic Apps or Azure
Durable Functions. Not only make these applications
based on Cloud Native Services. We also add intelligence to that application with
cognitive service. So we are in a AI has part of that.>>This is a really great diagram. I think that of all the diagrams
that I’ve seen out there, this is the most clear
because it really tells you exactly which
components are used.>>Yeah.>>It tells you which pieces
of Azure are used.>>Exactly.>>It tells you the language
that the thing is used in it. I like this particular diagram
because it really expresses that most people
have a hybrid application.>>Exactly.>>They don’t have an app
that’s written in one language.>>No, that’s correct.>>All right.>>Yeah. As part of the backend, we also have Go as
part of the languages. We also have Node.js
and obviously.NET Core.>>So you’ve also got Cosmos and SQL Server and Machine Learning
and all of that stuff, and the code for
every aspect of this is all in these repositories and the
Tailwind Traders Organization.>>Yes, exactly. As I mentioned, something important
here is that we use these fictitious scenarios to demonstrate how you
can use this service. These are not intended to be best practices or
architecture diagram, or best of partnering practices.>>Sure.>>Yeah. Our main objective here is how you can use
the Azure services in order to use it in
your own applications or use it as I get
the starting projects.>>I think what you’re saying is it’s not perfect production prescription.>>Yeah.>>But it’s still
a pretty good sample. I mean, I don’t want you
to put your sample down.>>No.>>Because while it may not be
exactly how to do it in production, it’ll teach you how to
use Machine Learning. It’ll teach you how to use Cosmos.>>Exactly, yeah.
That’s the intention.>>Yeah.>>Then we have the Coupon app. That is a desktop application. We have a Windows Forms
application and WPF, and for these we use.NET Core 3. As you mentioned, we also
use Machine Learning.NET, ML.NET, and that is part of
the backend services that we have.>>I see.>>Then we have
Son Applications Screens. So you can take a look at how
this application will look. If you don’t have an Azure account, you can start from
these options here. We also have some blog posts, videos that reference
to these applications. So for example, in Visual Studio
2019 launch event, some demos where related without Tailwind Traders. So you put it here. We released Tailwind Traders
as power of Connect 2018. So we have here the both
keynote that we did there. If I go to each repo, for example, I’m
going to the website.>>Okay.>>We keep the structure
of the repos. It’s basically a deploy
that is in our template. So you can deploy
different resources that you need for deploying this application. We also have some
PowerShell scripts or Bhatia scripts in order to automate
the process of the deployment. Then we have some documentation or images as part of the read me file. We also have obviously
the source code. Then we have the screenshot of
how the website will look like. We also keep an Azure pipeline. So you can go to the project, and you can take a look
how this was built.>>I really think this is great. Because you show up and
you see it’s healthy.>>Yeah, exactly.>>It’s a nice reminder
that this sample will build because you’re running at
a continuous integration pipeline.>>Yeah, exactly. If
we break the build, we also are showing that transparency of what we
break, so it’s part of that.>>As someone myself who
used to do a lot of work in the user groups and I like
to support user groups. This is a great opportunity for you the viewer to go and
take some of this. You don’t have to
run the whole thing, just take the piece
you’re interested in. Give a talk on it. Give a presentation. Add to it. Build something new.>>Exactly.>>Add some new feature, and then show that to your friends, your brown bag at work, your group. It’s a learning tool, and it’s a presentation tool, and it’s open source and
ready for you to use.>>Exactly, yeah. These Azure DevOps projects are open. So anyone can go here
and then take a look. How we built this application. How we the release, and also what is on
the backlog as well. So they can also up
in issues on GitHub, and they will have the back created in the repos here.>>The work item shows up in Azure DevOps from an issue
created in GitHub.>>Yes, exactly.>>Now, let me ask you this, do you want Pull requests? Do you want community members
to be involved?>>Absolutely, yeah. We always
request a review the Pull request. Actually, these builds are configured to run once that we
received a Pull request.>>Really? So if I
get a Pull request, even though I should talk to you first before I send the Pull request, it’ll go and run a build on the
Pull request to see if it builds.>>Exactly, yeah. Here we have the configuration for
triggered that built, once that we get a Pull request.>>That’s cool. Does the DevOps build everything,
even the mobile apps?>>Yes. We have the Azure pipeline for every single repo
that we have there. Something else that we keep hearing, this repo is a live running of
the website of the application.>>Wow.>>So you can go to Here we have the website running
in our production environment. That is the one that I have
deployed here in this subscription. So we’ll have the different resource
groups related to each demo, and we also have
the backend deployed. So as you mentioned, if you want to run the website, you don’t have to compile the whole solution and
deploy the whole solution. Don’t let the source code
of the website run it, and it will connect to our public endpoints that we
have for the backend.>>That’s cool.>>So I can start at if I want to or I can go up and
checkout It’s in the Microsoft Organization, and there’s Tailwind Traders. It’s the website and
all the different things. What’s the best homepage
do you think? You think Tailwind Traders
is the place to start?>>Yes.>>Right there. So
GitHub/Microsoft/TailwindTraders, and that’ll link you to all of the other repositories
from Kubernetes, to mobile, to functions. So many different great features, and products within
Azure that you’re using.>>Yeah, and we also have
here their Demo Scripts. So you can take a look at that.>>The Demo Scripts are
really interesting, because those are now
for the public to use. But this is the things
that when you and I are doing a demo for a conference, we’re reading those scripts. How to setup the demo. How to give a demo that’s successful. So a great way for people to get involved in speaking,
presenting, and teaching. If you want to use
this in your school, or your bootcamp, I think
we would encourage that.>>Yeah, absolutely. If
you want to contribute, you can always send a Pull request, and we will register.>>Fantastic. I’m learning
all about Tailwind Traders. It’s an Azure Open
Source Demo Project. I hope that you get involved. I’m learning all about it
today on Azure Friday. [MUSIC]
