I've recently been asked to redevelop an .Net 2.0 WinForms application with a back end SQL Server Express DB.
One of the requirements is to allow remote users access to the application, so I've been considering hosted options to avoid VPN setup. The data is not sensitive and does not fall under data protection act, so a basic security approach for the web will cover me.
I like the idea of using Azure for a few reasons, but I'm not sure if a good fit for a users base of 5 or 6 with no real scope to grow. I've never used Azure and I plan to develop using MVC and a SQL backend as this is my main skillset.
A few points in favour of Azure in my mind are:
Tight integration with the TFS preview that I'm using for this project
Easy to setup a sandpit and a live version
Easy maintenance as I expect other hosted options will require more knowledge of underlying OS
Sticking to a full Microsoft stack should hopefully make things simpler
From what I find on the Azure site the message is all about scalability, which is great if you need it.
My question is simply, do you need a large user base, or plans to grow quickly, to use azure or is it how we should be hosting apps now?
What you're asking here is the perfect case for Windows Azure Web Sites:
You get 10 web sites for free (no custom DNS, but this is perfect for your 'sandpit'/test version). The shared mode supports custom DNS and is very cheap.
Tight integration with TFS preview and GitHub
You don't need to worry about the underlying OS, you simply publish from Visual Studio or with TFS Preview.
Sticking to the Microsoft stack is the easiest solution, but other technologies work great aswell. Since you're talking about MVC I'm assuming you are considering ASP.NET MVC, which is a perfect match with Windows Azure. Take a look at the training kit for some good examples.
The day you'll need a solution which more scalable (meaning you'll have more users and more income) you can easily upgrade to a reserved instance or to a Cloud Service (Web/Worker Role).
About your question: "My question is simply, do you need a large user base, or plans to grow quickly, to use azure or is it how we should be hosting apps now?"
Windows Azure is a cloud service platform (includes PaaS as Cloud Services, IaaS as Windows Azure Virtual Machines and also Websites suggest by Sandrino above), and with cloud services you have ability to start very small and grow as much and as quickly as your user requirement is, so you can use Azure with both cases. On the other hand there are some advantages using certain offering depend on your which service you are going to use to run your application.
I think article (Section: "What Should I Use? Making a Choice") will explain the strategy about how you make a selection among various services.
This SO discussion does talks about the difference between cloud Services and Azure WebSites as well.

I am looking at possibly running some of our business on Azure.
I am trying to pick the services that would work best for my company, but I am getting mixed signals.
Because I am starting a new system, I want to pick the offerings that are not "legacy" (aka "current"). But there seems to be no way straight forward way to know that.
For example, this page of the Microsoft Documentation says
Cloud Services is similar to Service Fabric in degree of control versus ease of use, but it’s now a legacy service and Service Fabric is recommended for new development.
This page clearly states that Cloud Services is "legacy". However, you would never know this by going to the Cloud Services overview page. It has great marketing material that sells Cloud Services as a great option. But if I picked it, then I would be starting out on a platform that is in a legacy status.
Now I know that about Cloud Services vs Service Fabric. But there are tons offerings on Azure. I am trying to research them one by one to find out which ones are the most recent incarnation, but I feel like I am wasting my time.
Another example is storage. Lucky for me an Azure MVP answered my question on this one. Apparently, there is "older storage account" based disks and "managed" disks. Turns out managed disks are the new, easy way to do things. The storage account is harder. Still available, but not really what a new user should be picking. But again, this is very hard to find out unless someone who has been working with this stuff for a long time tells you.
I was about to start in on App Services and Web Apps, but I thought I would ask first to see if I am doing research that is already done and posted out there.
Is there somewhere that shows the current list of Azure services that you should look at if you are starting a new project?
I asked the similar question almost a year ago, and I even spoke with Azure Support Team after that. At that time, Microsoft did not officially state Cloud Service is legacy.
Does Azure App Service/Web App replace Azure Cloud Service?
We have been hosting our enterprise applications in Cloud Service since 2013, and a couple of them are in App Service. Here is my thought -
4 years ago we only have Cloud Service - Web Role and Worker Role,and App Service (formally named as Web App) is not fully ready for enterprise applications yet. Since App Service came up, Microsoft heavily promote App Service compare to Cloud Service. In addition, what I notice is Cloud Service did not get new features like App Service.
Service Fabric is quite new, and it doesn't have all the belts and whistles like App Service, so we might have to wait a bit for enterprise applications.
Only advantage of Cloud Service is you can remote desktop to a role instance, after the application is deployed.
If I host a new application in Azure today, I'll definitely use App Service.
Microsoft has published a list of Azure reference architectures. It was last updated in November 2016. You can browse it here, and there is some guidance given. But for example, you mentioned using Service Fabric (which is a great way to go for a robust app that really needs to scale), but Service Fabric isn't mentioned in the aforementioned resource.
I spend a lot of time running down Azure resources in relation to web applications (not to be confused with App Service Web Apps), and I have not found a definitive source of the type of info you're looking for personally.
I want to deploy Kentico 9 site on Azure and want to use shared file system for my media content, can you please suggest which Azure configuration (Azure Cloud Services or Azure Web Apps) I should referred?
I'd highly recommend going with Web App over Cloud Services. Mainly because Web App is almost like running on a regular server where Cloud Services is quite a bit different and harder to work with in my opinion.
Check this article out regarding some issues with Kentico and Azure Blog storage as well as how to setup your storage provider to only store media files.
http://www.kehrendev.com/blog/brenden-kehren/may-2016/problems-with-azure-and-kentico
Could you describe what do you mean by shared file system for my media content?
From my experience - it`s (a little bit) easier to deploy (and maintain) Kentico to Azure Web Apps but they do not provide so many customizations - in my humble opinion - the biggest one is you are not able to connect via remote desktop (but this is supported by Azure Cloud Services).
Please note - if you are using Cloud Services you must use Azure Blob Storage - source - which could be in conflict with your requirements.
You can find more information about Web Apps vs Cloud Services vs Virtual Machines on the mentioned page.
TL;DR; - if you do not need customizations, remote desktop and startup tasks - go for WebApps. If not, try to specify more requirements.
You can also check comparinson of the technologies from the Microsoft`s point of view here.
It's not clear who you want to share the media with...
If you want to share the assets amongst more Kentico instances or with a 3rd party system, I'd probably use the Azure Blob Storage. Kentico comes with a dedicated file provider for this exact use out of the box. It's called CMS.AzureStorage.
Using the blob storage is not a limiting factor in terms of hosting your app. You can still use all available options: Web Apps, VM or Cloud Service. There are some technical implications, of course. But they're all described in the documentation.
I recommend checking the comparison matrix to find a hosting option that suits your need best. Kentico recommends using App Service (Web Apps) for most projects as it's easiest to maintain. However, you can't use certain features like Kentico Windows services, for instance. Question is, do you really need them?
I need to connect to a middle tier (think Azure) between both my Windows store app and WP8 app. Windows Azure Mobile Services has been proffered as a/the solution.
But am I reading too much into the name "...MOBILES Services" (as one of the pieces is not a mobile app, but runs on desktops, laptops AND tablets)?
In my case, am I better off with Azure Cloud Services as opposed to Windows Azure Mobile Services?
Windows Azure Mobile Services is a fast, easy way to get a back-end in the cloud for your mobile apps and Windows 8 apps (it's fine if your Windows 8 apps aren't necessarily targeting mobile devices). It includes the things most commonly needed in a back-end, such as authentication, database storage, and push notifications. There's no server-side development needed here, you just request the back-end and moments later it's ready to use; however, if you do want server-side logic you can add it in the form of JavaScript scripts.
Alternatively, you could build your own back end in the cloud using a combination of Windows Azure Cloud Services such as the Compute, Storage, and SQL Database services. You have access to more features at this level, but you also are doing your own development. You can write server-side logic in C#, VB.NET, PHP, Java, Python, etc. as you prefer.
Which should you use?
If Windows Azure Mobile Services meets your needs, and you'd rather focus on your mobile app than learning anything cloud-specific, that's likely the best path for you.
If you're conversant with the Windows Azure platform, and need features different from what WAMS provides, that suggests creating your own back end with Cloud Services.
If you're not sure which way to go, I suggest experimenting first with WAMS since it is quick and painless to get started.
Azure mobile services is designed to get you up and going with storing data, push notifications and authentication whichever of those components you might need.
It abstracts the need of creating a data access layer and a web/wcf service to access it from your applications; it's simply there to boilerplate as much functionality off the bat.
This however does not mean that it is only for mobile applications, behind it all is a normal SQL Azure database and an API that you can use from any .NET based application.
I would reason that if you need more than basic CRUD operations and won't be using authentication and push notifications, I would roll my own set of APIs and DAL and use cloud services instead.
If you need a flexible schema, boilerplate data access and want to use some of the other mobile services, it would suit you quite well.
Here is a link to getting going with mobile services from a non Windows8 or WP - ASP application : link
Exist three ways for deploy Node.js app on Windows Azure, web-role, web-site and git-azure (link). I don't know whitch is most efficient for my needs. My app is readability algorithm with RESTful API, whitch parse news sites, simple computing, but highload. Of course, I need transparent horizontal scaling. I hope for your help.
My $0.02.
If your product is only based on Node.js, without many layers and components such as background workers, business logic layer and API layer, Windows Azure Web Site should be the best choice. It's very simple to deploy Node.js application through Git, GitHub, TFS, FTP, etc. It also provides scaling-up (in reserve mode) and scaling-out options. But keep in mind that all applications under Windows Azure Web Site will be running in 32bit WOW mode.
Windows Azure Web Role is similar as Windows Azure Web Site, but you need configure the Node.js environment by yourself. (If you are using the azure powershell tool, it can help you establish the node stuff by using some startup commands.) If you need something working in worker roles, or the caching (not the shared caching), Web Role may be better.
I've never heard about the git-azure but it looks like a tooling that you can host more than one node application on worker role.
What type of projects/software applications are suitable for Azure and why?
Thanks
Rather than thinking of what can be supported in Azure, it might be more helpful to think about its challenges as you decide to port your app over:
Web applications. Since a Web Role hosts IIS, you'll generally have little issue porting a general-purpose asp.net or asp.net mvc website to Azure. There are some glitches you'll run into - see my related answer for more details.
UI. If your app has specific output similar to a WinForms app, you won't be able to run it since you have no video output.
GPU dependencies. If you're doing some background processing dependenton a specific GPU, you won't be able to run in an Azure VM.
Registry and other system-level access. If your app needs to update the registry or run an MSI, you won't be able to install your app.
Instance affinity. If your app requires session stickiness (e.g. a logged-in user MUST visit the same server instance with each access), you won't be able to accomplish this.
COM interop. COM interop is very limited, since you can't install anything via the registry. If you rely on Excel Services, you won't have that capability.
SQL limitations. SQL Azure is limited to 50GB today, and offers no ability to custom-tune the server instance. Also, while it does support a big subset of SQL Server, it doesn't support 100% of SQL Server, so it's possible some of your sprocs may no longer work. There's no SQL Agent today, so you'd need to recreate that functionality in a worker process.
That's just a quick braindump of some challenges you might run into - I'm sure there are others.
Just keep in mind that Azure is providing Windows 2008 Server images for your app to run on, so if your app can run in that environment today, and doesn't require things I listed, you should be in pretty good shape.
You can make most of the .NET projects working in Azure. Azure has support of following project types: web site (both ASP.NET and ASP.NET MVC), worker (background application) and wcf service.
Don't forget security too - there's various ways of authenticating onto Azure but none are as simple as just setting IIS/ASP to windows auth.
