Deploying Applications other than WebApp using Azure Resource Manager - azure

I am currently looking into using ARM to deploy new environments of our Azure Components. We have a lot of web apis that are deployed to Cloud Services, since we need access to the underlying OS to get CPU usage for App Dynamics metrics. When reading through ARM, it seems as if they are deprecating Cloud Services, but I have some confusion about what is replacing it. I see that you can create Web Apps using this and use Publish from Visual Studio to deploy the app it, but I see no options for Cloud Services. So what is the preferred method to do this? Creating a VM and deploying using Web Deploy? What about VM scaling. Any help would be greatly appreciated.

My company is in the process of moving a legacy app to Azure using Cloud Services and we were concerned about the future of Cloud Services. Since we are somewhat early into the project and would like to use the ARM model we thought it would be easier to make a move now if we knew the future. After a few conversations with project leads at Microsoft on this topic we were only told that we should continue working with Cloud Services as they would continue to be supported.
It's quite clear that the move to ARM was not well thought out in terms of direction and consequences of existing services that many people are already using. Reading between the lines I would say that there is no plan to convert Cloud Services from the ASM to ARM model.

If application insights (https://azure.microsoft.com/en-us/services/application-insights/) are sufficient for your monitoring needs, then you can use web apps. These can be deployed via ARM, and can automatically deploy from a git repo or web deploy package. See this example:
https://github.com/Azure/azure-quickstart-templates/tree/master/201-web-app-github-deploy
The issue here that you may be trying to do operations which are restricted by the web app sandbox.
Failing that, you can use an ARM template to set up a VM and then invoke a custom site extension which will run powershell code to do further provisioning. This powershell code can fetch any package that you may want to install. See this ARM template for example: https://github.com/Azure/azure-quickstart-templates/tree/9ad72f1f5f0008c14311be79eee036b871712394/201-list-storage-keys-windows-vm
Once the VM is created you would be able to modify it and scale as needed.

How can I deploy Azure Functions to in-house datacenters?

This article discusses that an Azure function can easily be deployed in local datacenters without Azure.
Open source runtime that runs anywhere
The Functions runtime, templates, UI and underlying WebJobs SDK are all open source projects being developed publically. The Azure Function runtime will be portable so you can run Functions anywhere - on Azure, in your datacenter or other clouds.
Question:
How can I create an installer package that I can give to customers?
What are the requirements of this installer?
Can the target environment be ASP.NET core or run on Linux/Mac?
Azure Functions Runtime (currently in preview) enables an on premise deployment of Azure Functions, which includes portal, functions execution runtime and other components, all in an installer you can use. This also removes some of the cloud dependencies like Azure Storage, allowing you to run all within your internal network.
Currently, .NET Core is not supported, so you'll need to deploy this on a Windows environment, but we're actively working on migrating the core Azure Functions runtime bits and the on premise Azure Functions Runtime would follow.
You can find the requirements on the document I've linked to.
Another option is do download the functions releases directly from the repository here, but that does not have an installer that enables an end-to-end deployment experience (or components like the portal), so you'd need to provide that.

How do you create an installer for Azure Web Apps / Azure Websites

I am a software vendor with a .net web solution that I want customers to be able to easily install / deploy into Azure Web Web Apps / Azure Websites along with a Sql Azure backend. I can't find any installer tool that supports this scenario. I have also looked into the Azure Marketplace but it seems the only option there is to create VM images. I want my customer's to avoid having to deploy to an manage VMs and adopt the IaaS model. Instead they should be able to install to Azure Web Apps with a package that copies all the web solution files and installs and connects the Azure Sql. Is this possible or will I have to manually deploy and configure Azure solution for each customer?
You can use the VS Marketplace to do the deployment. What you need is to create an ARM template. There is a huge number of samples here: https://github.com/Azure/azure-quickstart-templates - you can pick one of the web app ones - for example: https://azure.microsoft.com/en-us/resources/templates/201-web-app-sql-database/ - has a SQL database linked to a web app.
The ARM template allows you to do a "no-hands" deployment of the resources and know when they are ready for further action. You can also deploy from any of the supported continuous deployment options (see the template with a GitHub connection as an example) or you can use ftp/msdeploy after the deployment is successful.
This is a good tutorial https://learn.microsoft.com/en-us/azure/azure-resource-manager/vs-azure-tools-resource-groups-deployment-projects-create-deploy
This is the github example mentioned in previous answer

Release Management Azure Website

How can I publish to an Azure Website (NO VM!) using Microsoft Release Management.
At the moment, ms release management only seems to support deploying to Azure VM's. I like MS Release Management system as it lets me control my deployment variables across multiple deployment stages.
Basically, this is not a supported scenario out of the box.
Your best bet here is to use an agent-based release template with a "springboard" server to manage the release, and custom PowerShell scripts that use the Azure SDK to interact with Azure. One of my colleagues did the leg work to figure it out a few months ago, and has a few comprehensive blog posts describing how he accomplished deploying an Azure Web Application via RM.
Visual Studio Release Management now offers built-in steps to manage Azure App Services. In a Release Management process add the Azure App Service Deploy step, and configure for your website. Note that this step requires your site to be published as a .zip file.
In addition to the deploy step, it is best practice to deploy to an inactive slot, or stop / start the site using the Azure App Service Manage steps in Release Management.
For now, you should take a look at the new build system, it has an out of box task to deploy a package to azure web app.

I am a bit confused about deployment of cloud services, and particular whether just code can be replaced

Just getting used to VS2012 publishing of Cloud Services. At present I have a one instance webrole which contains a MVC3 application. I can publish it to Azure without issue, and it creates the Cloud Service>Web Role>VMs. Fine. Takes a little while.
However when I do a little code change how can I migrate just this code change without replacing all the VMs that implement the WebRole etc.
It seems that Code and infrastructure are inseparable, or have I misunderstood. Is there a way to just update the code bit?
Thanks.
When you roll out an update, you upload an entire package containing not only your code files, but also the configuration for the VM, such as # of instances, ports to open on the firewall, local resources to allocate, etc. These configuration settings are part of the code package - so there is more going on than just updating code files.
However, there are a couple of methods you can use to have more granular control over updates.
Use Web Deploy. One thing to keep in mind, is that any automatic service updates will restore your website to the last fully-deployed package, which may not be as up-to-date. You would only want to use this in staging, then do a full package update for production rollout.
Use an Azure Web Site instead, which allows continuous integration with your source control provider, and direct updates to the code.
Use an Iaas VM instead. These are basically the same as running your own custom server in the Azure cloud, and you have full control over the OS. However, you also have full responsibility for keeping the OS updated and secure.
You can also enable RDP to your Azure Web Role VM's. You will find all your code files there and IIS, but I wouldn't recommend updating your code this way for the same reasons listed in #1.
The code and infrastructure, in a cloud service, are actually separate. All you upload is a deployment package containing just your code and supporting libraries / files. You don't upload a vhd. Azure provides that for you, spinning up a vhd, and then accessing your code on a file folder on that vhd. Same process happens each time you scale out to more instances.
when you make a code change, you build a new deployment package and deploy that. If you do it as an in-place update (vs delete+redeploy), each role is updated on each instance (when you have multiple instances of a role, they're not all updated at the same time). You can even specify that you only want a single role within the deployment to be updated (helpful if, say, you have a worker role in addition to your web role, and want to leave all the worker role instances running).
when the code update happens, the VMs aren't replaced, but they are recycled, and when they start back up, they are running the updated code.
You can use WebDeploy with Cloud Services in production across multiple servers using the AzureWebFarm project (disclaimer: I maintain it).
Alternatively, you can also use the excellent Octopus Deploy deployment technology in conjunction with the AzureWebFarm.OctopusDeploy project (disclaimer: I maintain this one too).
To be honest though, if you just have a simple web app then I wouldn't both with cloud services - I'd just use Web Sites. Feel free to check out my blog post to see the situations which might force you to use cloud services though.
If you enable WebDeploy on the cloud service, you can use web deploy to publish the MVC application.
See http://msdn.microsoft.com/en-us/library/windowsazure/ff683672.aspx for details.
All of the above answers are correct and if you are trying to change your code for a production service you definitely want to do an in place upgrade as described. However, frequently during the dev/test phase or troubleshooting I want to make one small change and test it out quickly. To do this check out http://blogs.msdn.com/b/kwill/archive/2013/09/05/how-to-modify-a-running-azure-service.aspx which describes how to modify the code via RDP to the Azure VM.

Can I cross develop an app for IIS and Azure?

We are starting to build out some new tech and I want to know if it is possible to cross develop a web app to run natively in Azure (ie, use Azure specific stuff like storage) but also run locally on our test servers and accommodate internal deployments natively on IIS?
I know I can host them from a dev box in a simulated Azure environment and I know that I can interface the Azure parts out and write in non-azure counterparts. It just seems like this should be a solved problem.
If you want to run Azure applications on-premises (and using non-development Azure storage), you must run a Microsoft Private Cloud. It requires special hardware and licensing costs, so don't expect it to run on what you have today.
