Shayne is joined by Ralph Squillace at Microsoft Ignite 2019 to hear more about Cloud Native Application Bundles (CNAB)
[01:05] - CNAB, What problems are we trying to solve?[03:42] - Is this just a Microsoft thing, who's involved?[07:10] - Who is this for? Developers, IT Ops, inner loop...[11:45] - How would we distribute these apps or bundles?[13:10] - Ralph gets into a demo![17:15] - A larger complex example.LinksFree Azure Account - https://aka.ms/cldntvshw/freeazureCloud Native Application Bundle (CNAB) - https://cnab.ioPorter - https://porter.shHelm - https://helm.shRudr - Rudr is an Open Application Model (OAM) implementation for Kubernetes. https://github.com/oam-dev/rudrdapr - An event-driven, portable runtime for building microservices on cloud and edge. https://dapr.io/Azure Arc - https://azure.microsoft.com/services/#cloudnative #cnab #cloudnativeapps
Container registries are repositories for storing container images, but who should use them? Which one should we choose and why are they important for cloud native applications? Steve Lasker sits with us in Building 99 today and talks about registries and more specifically Azure Container Registry and the practices around using them for your applications.
[03:50] - How do I choose the registry to use?
[06:15] - Additional benefits to registries beyond to being close to my deployment?
[08:10] - How do you think about life cycle management, from the point of development to long term patching support? I've seen acr build, and tasks, but what's the magic here?
[11:00] - Security patching, does that happen automatically with ACR?
[14:00] - Steve breaks down the trigger of an automated build by ACR
[18:25] - What's coming next?

Microservices based applications consist of multiple services and are built with a variety of programming languages. Based on the business use case, you can pick the most appropriate technology to build your service. gRPC can be one of those choices.
Today we chat with Sourahb to find out more about gRPC and ASP.NET Core apps.
[01:04] - Where does gRPC come from?
[02:40] - What's different about gRPC, why this?
[06:15] - Contract based development, types, strongly type clients, like WCF?
[09:45] - Demo time!
[17:23] - What's next for .NET Core and gRPC / Roadmap?
[19:22] - Are there any challenges running gRPC?

A critical characteristic of cloud native architectures it the ability to dynamically scale and support massive numbers of users, events, and requests on these distributed applications and teams. Serverless can help in handling these challenges without having to worry about infrastructure or even an entire application. Jeff jumps into the show production and chats with us on how this fits into the plan for cloud native apps.
[02:20] – What are the benefits?
[04:50] – Are there other challenges?
[07:43] – Jeff shows an awesome demo on scaling!
[11:45] – How do we think about serverless as a part of our solution first?
[14:20] – Running serverless in a container
[16:30] – Where is serverless going?

Azure App Configuration is a developer-focused service in Azure that manages and distributes application settings. It helps implement patterns, such as the 12-factor app, and is particularly useful for cloud native and other distributed applications. In this episode, we'll discuss how you can use Azure App Configuration to simplify management of and secure access to your application settings.

Cloud Native Show Live Episode #1 with Shayne and Glenn. They talk about Cloud Native development and build out a weather API application. First, they'll show you how to build an API with configuration and building an Azure DevOps pipeline. That pipeline will build a container image to push it to an Azure Container Registry.

One of the "Factors" in cloud native applications states you should store your configuration and settings outside of your core application code. In this episode, Shayne talks with Andrew to get a run down on how the configuration options in .NET Core allows for layers of configurability and abstractions for your app.
