The Windows Azure Software Development Kit (SDK) and the Windows Azure Training Kit (WATK)

BuckWoody — Wed, 12 Sep 2012 13:40:40 GMT

Windows Azure is a platform that allows you to write software, run software, or use software that we've already written. We provide lots of resources to help you do that - many can be found right here in this blog series. There are two primary resources you can use, and it's important to understand what they are and what they do.

The Windows Azure Software Development Kit (SDK)

Actually, this isn't one resource. We have SDK's for multiple development environments, such as Visual Studio and also Eclipse, along with SDK's for iOS, Android and other environments. Windows Azure is a "back end", so almost any technology or front end system can use it to solve a problem.

The SDK's are primarily for development. In the case of Visual Studio, you'll get a runtime environment for Windows Azure which allows you to develop, test and even run code all locally - you do not have to be connected to Windows Azure at all, until you're ready to deploy.

You'll also get a few samples and codeblocks, along with all of the libraries you need to code with Windows Azure in .NET, PHP, Ruby, Java and more.

The SDK is updated frequently, so check this location to find the latest for your environment and language - just click the bar that corresponds to what you want:

http://www.windowsazure.com/en-us/develop/downloads/

The Windows Azure Training Kit (WATK)

Whether you're writing code, using Windows Azure Virtual Machines (VM's) or working with Hadoop, you can use the WATK to get examples, code, PowerShell scripts, PowerPoint decks, training videos and much more. This should be your second download after the SDK. This is all of the training you need to get started, and even beyond. The WATK is updated frequently - and you can find the latest one here:

http://www.windowsazure.com/en-us/develop/net/other-resources/training-kit/

There are many other resources - again, check the http://windowsazure.com site, the community newsletter (which introduces the latest features), and my blog for more.

Windows Azure Database (SQL Azure) Development Tip

BuckWoody — Wed, 15 Aug 2012 14:55:44 GMT

When you create something in the cloud, it's real, and you're charged for it. There are free offerings, and you even get free resources with your Microsoft Developer Network (MSDN) subscription, but there are limits within those. Creating a 1 GB database - even with nothing in it - is a 1 GB Database. If you create it, drop it, and create it again 2 minutes later, that's 2 GB of space you've used for the month. Wait - how do I develop in this kind of situation?

With Windows Azure, you can simply install the free Software Development Kit (SDK) and develop your entire application for free - you need never even log in to Windows Azure to code. Once you're done, you simply deploy the app and you start making money from the application as you're paying for it.

Windows Azure Databases (The Artist Formerly Known As SQL Azure) is a bit different. It's not emulated in the SDK - because it doesn't have to be. It's just SQL Server, with some differences in feature set. To develop in this environment, you can use SQL Server, any edition. Be aware of the feature differences, of course, but just develop away - even in the free "Express" or LocalDB flavors - and then right-click in SQL Server Management Studio to script objects. Script the database, but change the "Advanced" selection to the Engine Type of "SQL Azure". Bing.

Although most all T-SQL ports directly, one thing to keep in mind is that you need a Clustered Index on every table. Often the Primary Key (PK) is a good choice for that.

The Importance of Paranoia for the Technical Professional

BuckWoody — Wed, 08 Aug 2012 12:19:11 GMT

I recently read a blog post from a technical professional who’s account had been hacked (http://www.wired.com/gadgetlab/2012/08/apple-amazon-mat-honan-hacking/all/) – not because he used poor passwords or unsafe practices, but because the hackers used some social engineering to get around the safety he had put into place.

While I won’t focus on the particulars of his situation, the interesting part of his loss was the fragility of the security of his data. In this case, he lost personal data – with no way to replace it. Two things stood out for me in his article: the chain of security through his accounts, and the single-source of data he had.

In this case, someone contacted the vendor and pretended to be this person. Using easily obtained information, they simply gained access to the account, and didn’t even have to hack the password. From there, the chain was that using various convenience-features, the hackers could delete the smartphone, and then on to the laptop the person owned. They completely wiped that out, and this is where there is an issue – he had his data on that laptop, and on the same vendor’s cloud backup. Since the hacker *was* the account owner by that time, they wiped out both. The person’s personal pictures, etc were gone forever. From there the hackers impersonated the person on Twitter and made racist and other statements to embarrass the person.

Although lots of features are available in all vendor products, I’ve always been….paranoid about using them. I try to follow the “moats and bridges” approach to security, meaning that one account or feature doesn’t lead to another. I don’t link things together that can be used to attach to more than one account, even when it's a cool new feature. One public logon from an airport’s “free” wifi (which I never use, by the way) can lead to these attacks – even if you don’t think you’re logging on. Ever check your mail from the airport? Do you have more than one mail account in your mail client? You could be hacked. I realize most client software does a good job of trying to prevent this, but I use my own MiFi device which I have set to the highest encryption I can.

I also keep lots of data in the cloud – but that’s not the only place. Periodically I have my important data backed up to a local drive,which I rotate to another secure location. After all, I’ve moved most of my books, pictures, scans, everything to a digital format. There’s no way I’m keeping that in just one place, or on just one vendor.

There are other things you can do to protect yourself – a great list is here: http://gizmodo.com/5932663/9-things-you-absolutely-must-do-to-keep-your-online-identity-secure

When I help clients design solutions on Windows Azure, I recommend another copy of the storage wherever possible – even on other vendor's cloud storage or locally on a drive, or both. I’m paranoid that way – I don’t want them to lose data. We take extraordinary precautions against losing data. Azure data has three copies on separate fault domains, and then those three are copied again to another physical datacenter automatically, that’s just built into the system. Even so, I recommend periodic backups to other
locations of data the client can’t easily re-generate.

While we provide lots of tools, information and guidance about security and protection in Windows Azure, ultimately it's up to you to properly secure your assets and plan for disaster recovery. That's true of any cloud provider - you need to learn the platform well to understand how to protect your data.

What I architect in Windows Azure I practice at home. Read that blog post, and I think you will agree it’s good to be a little paranoid. Sometimes they really are out to get you.

Windows Azure Visio Shapes

BuckWoody — Wed, 25 Jul 2012 13:44:23 GMT

Normally when I diagram a solution for a customer, I use whatever they are comfortable with. I do most of my work these days in OneNote, especially when it’s an Architecture Design Session (ADS), since I can capture notes, handwriting, drawings, web pages, whiteboards, camera shots and even voice. In fact you can search on most of those.

Simplicity is the rule – I just want to capture enough data to move to the next phase of the project and ensure everyone understands what we are doing. When we get to that next phase, I like to use Visio. It’s a vector-based drawing and diagraming tool, which means you can zoom in or out a great deal without a loss of definition, in most cases. For complicated diagrams, this is essential.

The basic shapes in Visio are fine – and there are some computer and network shapes I use there all the time. But I wanted something that would show the basic parts of Windows Azure, from our IaaS to our PaaS to the SaaS shapes, as well as security federation providers like Google or Yahoo that you can leverage in Azure.

So I created some shapes, and I’ll share them here.

In the Cloud, Everything Costs Money

BuckWoody — Tue, 10 Jul 2012 12:55:50 GMT

I’ve been teaching my daughter about budgeting. I’ve explained that most of the time the money coming in is from only one or two sources – and you can only change that from time to time. The money going out, however, is to many locations, and it changes all the time. She’s made a simple debits and credits spreadsheet, and I’m having her research each part of the budget. Her eyes grow wide when she finds out everything has a cost – the house, gas for the lawnmower, dishes, water for showers, food, electricity to run the fridge, a new fridge when that one breaks, everything has a cost. She asked me “how do you pay for all this?” It’s a sentiment many adults have looking at their own budgets – and one reason that some folks don’t even make a budget. It’s hard to face up to the realities of how much it costs to do what we want to do.

When we design a computing solution, it’s interesting to set up a similar budget, because we don’t always consider all of the costs associated with it. I’ve seen design sessions where the new software or servers are considered, but the “sunk” costs of personnel, networking, maintenance, increased storage, new sizes for backups and offsite storage and so on are not added in. They are already on premises, so they are assumed to be paid for already.

When you move to a distributed architecture, you'll see more costs directly reflected. Store something, pay for that storage. If the system is deployed and no one is using it, you’re still paying for it. As you watch those costs rise, you might be tempted to think that a distributed architecture costs more than an on-premises one.

And you might be right – for some solutions. I’ve worked with a few clients where moving to a distributed architecture doesn’t make financial sense – so we didn’t implement it. I still designed the system in a distributed fashion, however, so that when it does make sense there isn’t much re-architecting to do.

In other cases, however, if you consider all of the on-premises costs and compare those accurately to operating a system in the cloud, the distributed system is much cheaper. Again, I never recommend that you take a “here-or-there-only” mentality – I think a hybrid distributed system is usually best – but each solution is different. There simply is no “one size fits all” to architecting a solution.

As you design your solution, cost out each element. You might find that using a hybrid approach saves you money in one design and not in another. It’s a brave new world indeed.

So yes, in the cloud, everything costs money. But an on-premises solution also costs money – it’s just that “dad” (the company) is paying for it and we don’t always see it. When we go out on our own in the cloud, we need to ensure that we consider all of the costs.

Creating a Corporate Data Hub

BuckWoody — Tue, 26 Jun 2012 14:36:41 GMT

The Windows Azure Marketplace has a rich assortment of data and software offerings for you to use – a type of Software as a Service (SaaS) for IT workers, not necessarily for end-users. Among those offerings is the “Data Hub” – a codename for a project that ironically actually does what the codename says.

In many of our organizations, we have multiple data quality issues. Finding data is one problem, but finding it just once is often a bigger problem. Lots of departments and even individuals have stored the same data more than once, and in some cases, made changes to one of the copies. It’s difficult to know which location or version of the data is authoritative.

Then there’s the problem of accessing the data. It’s fairly straightforward to publish a database, share or other location internally to store the data. But then you have to figure out who owns it, how it is controlled, and pass out the various connection strings to those who want to use it. And then you need to figure out how to let folks access the internal data externally – bringing up all kinds of security issues. Finally, in many cases our user community wants us to combine data from the internally sources with external data, bringing up the security, strings, and exploration features up all over again.

Enter the Data Hub. This is an online offering, where you assign an administrator and data stewards. You import the data into the service, and it’s available to you - and only you and your organization if you wish.

The basic steps for this service are to set up the portal for your company, assign administrators and permissions, and then you assign data areas and import data into them. From there you make them discoverable, and then you have multiple options that you or your users can access that data. You’re then able, if you wish, to combine that data with other data in one location.

So how does all that work? What about security? Is it really that easy? And can you really move the data definition off to the Subject Matter Experts (SME’s) that know the particular data stack better than the IT team does?

Well, nothing good is easy – but using the Data Hub is actually pretty simple. I’ll give you a link in a moment where you can sign up and try this yourself. Once you sign up, you assign an administrator. From there you’ll create data areas, and then use a simple interface to bring the data in. All of this is done in a portal interface – nothing to install, configure, update or manage.

After the data is entered in, and you’ve assigned meta-data to describe it, your users have multiple options to access it. They can simply use the portal – which actually has powerful visualizations you can use on any platform, even mobile phones or tablets.

Your users can also hit the data with Excel – which gives them ultimate flexibility for display, all while using an authoritative, single reference for the data. Since the service is online, they can do this wherever they are – given the proper authentication and permissions. You can also hit the service with simple API calls, like this one from C#: http://msdn.microsoft.com/en-us/library/hh921924

You can make HTTP calls instead of code, and the data can even be exposed as an OData Feed. As you can see, there are a lot of options.

You can check out the offering here: http://www.microsoft.com/en-us/sqlazurelabs/labs/data-hub.aspx and you can read the documentation here: http://msdn.microsoft.com/en-us/library/hh921938

Windows Azure – Write, Run or Use Software

BuckWoody — Wed, 13 Jun 2012 22:47:00 GMT

Windows Azure is a platform that has you covered, whether you need to write software, run software that is already written, or Install and use “canned” software whether you or someone else wrote it. Like any platform, it’s a set of tools you can use where it makes sense to solve a problem.

You can click on the graphic below for a larger picture of these components, or download a poster with more details here.

The primary location for Windows Azure information is located at http://windowsazure.com. You can find everything there from the development kits for writing software to pricing, licensing and tutorials on all of that.

I have a few links here for learning to use Windows Azure – although it’s best if you focus not on the tools, but what you want to solve. I’ve got it broken down here into various sections, so you can quickly locate things you want to know. I’ll include resources here from Microsoft and elsewhere – I use these same resources in the Architectural Design Sessions (ADS) I do with my clients worldwide.

There is also a great video series on Cloud Fundamentals here, if you have some time to watch them. It's a great series that covers a lot of ground.

Write Software

Also called “Platform as a Service” (PaaS), Windows Azure has lots of components you can use together or separately that allow you to write software in .NET or various Open Source languages to work completely online, or in partnership with code you have on-premises or both – even if you’re using other cloud providers. Keep in mind that all of the features you see here can be used together, or independently. For instance, you might only use a Web Site, or use Storage, but you can use both together. You can access all of these components through standard REST API calls, or using our Software Development Kit’s API’s, which are a lot easier. In any case, you simply use Visual Studio, Eclipse, Cloud9 IDE, or even a text editor to write your code from a Mac, PC or Linux.

Components you can use:

Azure Web Sites: Windows Azure Web Sites allow you to quickly write an deploy websites, without setting a Virtual Machine, installing a web server or configuring complex settings. They work alone, with other Windows Azure Web Sites, or with other parts of Windows Azure. Read more about deciding to use Web Sites or Roles.

Web and Worker Roles: Windows Azure Web Roles give you a full stateless computing instance with Internet Information Services (IIS) installed and configured. Windows Azure Worker Roles give you a full stateless computing instance without Information Services (IIS) installed, often used in a "Services" mode. Scale-out is achieved either manually or programmatically under your control.

Storage: Windows Azure Storage types include Blobs to store raw binary data, Tables to use key/value pair data (like NoSQL data structures), Queues that allow interaction between stateless roles, and a relational SQL Server database.

Other Services: Windows Azure has many other services such as a security mechanism, a Cache (memcacheD compliant), a Service Bus, a Traffic Manager and more. Once again, these features can be used with a Windows Azure project, or alone based on your needs.

Windows Azure Mobile Services: A simple framework service which enables you to quickly develop the back-end for mobile services. For the front-end, check out the iOS SDK, news about the Android SDK, and the Windows Phone SDK.

Various Languages: Windows Azure supports the .NET stack of languages, as well as many Open-Source languages like Java, Python, PHP, Ruby, NodeJS, C++ and more.

Use Software

Also called “Software as a Service” (SaaS) this often means consumer or business-level software like Hotmail or Office 365. In other words, you simply log on, use the software, and log off – there’s nothing to install, and little to even configure. For the Information Technology professional, however, It’s not quite the same. We want software that provides services, but in a platform. That means we want things like Hadoop or other software we don’t want to have to install and configure.

Components you can use:

Kits: Various software “kits” or packages are supported with just a few clicks, such as Umbraco, Wordpress, and others.

Windows Azure Media Services: Windows Azure Media Services is a suite of services that allows you to upload media for encoding, processing and even streaming – or even one or more of those functions. We can add DRM and even commercials to your media if you like. Windows Azure Media Services is used to stream large events all the way down to small training videos.

High Performance Computing and “Big Data”: Windows Azure allows you to scale to huge workloads using a few clicks to deploy Hadoop Clusters or the High Performance Computing (HPC) nodes, accepting HPC Jobs, Pig and Hive Jobs, and even interfacing with Microsoft Excel.

Windows Azure Marketplace: Windows Azure Marketplace offers data and programs you can quickly implement and use – some free, some for-fee.

Run Software

Also known as “Infrastructure as a Service” (IaaS), this offering allows you to build or simply choose a Virtual Machine to run server-based software.

Components you can use:

Persistent Virtual Machines: You can choose to install Windows Server, Windows Server with Active Directory, with SQL Server, or even SharePoint from a pre-configured gallery. You can configure your own server images with standard Hyper-V technology and load them yourselves – and even bring them back when you’re done. As a new offering, we also even allow you to select various distributions of Linux – a first for Microsoft.

Windows Azure Connect: You can connect your on-premises networks to Windows Azure Instances.

Storage: Windows Azure Storage can be used as a remote backup, a hybrid storage location and more using software or even hardware appliances.

Decision Matrix

With all of these options, you can use Windows Azure to solve just about any computing problem. It’s often hard to know when to use something on-premises, in the cloud, and what kind of service to use.

I’ve used a decision matrix in the last couple of years to take a particular problem and choose the proper technology to solve it. It’s all about options – there is no “silver bullet”, whether that’s Windows Azure or any other set of functions. I take the problem, decide which particular component I want to own and control – and choose the column that has that box darkened. For instance, if I have to control the wiring for a solution (a requirement in some military and government installations), that means the “Networking” component needs to be dark, and so I select the “On Premises” column for that particular solution. If I just need the solution provided and I want no control at all, I can look as “Software as a Service” solutions.

Security, Pricing, and Other Info

Security: Security is one of the first questions you should ask in any distributed computing environment. We have certification info, coding guidelines and more, even a general “Request for Information” RFI Response already created for you.

Pricing: Are there licenses? How much does this cost? Is there a way to estimate the costs in this new environment?

New Features: Many new features were added to Windows Azure - and you can keep up to date with community information released monthly here: http://blogs.msdn.com/b/davidmcg/

Windows Azure Cookbooks: Great resource for architecture solutions - http://www.notsotrivial.net/blog/category/Architecture.aspx

Support: Software Support on Virtual Machines, general support, support plans

Windows Azure Capability Discussion Presentation and Windows Azure Solution Implementer Guide and Windows Azure Business Priorities Guide

Windows Azure End to End Examples

BuckWoody — Tue, 29 May 2012 13:45:59 GMT

I’m fascinated by the way people learn. I’m told there are several methods people use to understand new information, from reading to watching, from experiencing to exploring.

Personally, I use multiple methods of learning when I encounter a new topic, usually starting with reading a bit about the concepts. I quickly want to put those into practice, however, especially in the technical realm. I immediately look for examples where I can start trying out the concepts. But I often want a “real” example – not just something that represents the concept, but something that is real-world, showing some feature I could actually use.

And it’s no different with the Windows Azure platform – I like finding things I can do now, and actually use. So when I started learning Windows Azure, I of course began with the Windows Azure Training Kit – which has lots of examples and labs, presentations and so on. But from there, I wanted more examples I could learn from, and eventually teach others with. I was asked if I would write a few of those up, so here are the ones I use.

CodePlex

CodePlex is Microsoft’s version of an “Open Source” repository. Anyone can start a project, add code, documentation and more to it and make it available to the world, free of charge, using various licenses as they wish. Microsoft also uses this location for most of the examples we publish, and sample databases for SQL Server.

If you search in CodePlex for “Azure”, you’ll come back with a list of projects that folks have posted, including those of us at Microsoft. The source code and documentation are there, so you can learn using actual examples of code that will do what you need. There’s everything from a simple table query to a full project that is sort of a “Corporate Dropbox” that uses Windows Azure Storage.

The advantage is that this code is immediately usable. It’s searchable, and you can often find a complete solution to meet your needs. The disadvantage is that the code is pretty specific – it may not cover a huge project like you’re looking for. Also, depending on the author(s), you might not find the documentation level you want.

Link: http://azureexamples.codeplex.com/site/search?query=Azure&ac=8

Tailspin

Microsoft Patterns and Practices is a group here that does an amazing job at sharing standard ways of doing IT – from operations to coding. If you’re not familiar with this resource, make sure you read up on it. Long before I joined Microsoft I used their work in my daily job – saved a ton of time. It has resources not only for Windows Azure but other Microsoft software as well.

The Patterns and Practices group also publishes full books – you can buy these, but many are also online for free. There’s an end-to-end example for Windows Azure using a company called “Tailspin”, and the work covers not only the code but the design of the full solution. If you really want to understand the thought that goes into a Platform-as-a-Service solution, this is an excellent resource.

The advantages are that this is a book, it’s complete, and it includes a discussion of design decisions. The disadvantage is that it’s a little over a year old – and in “Cloud” years that’s a lot. So many things have changed, improved, and have been added that you need to treat this as a resource, but not the only one. Still, highly recommended.

Link: http://msdn.microsoft.com/en-us/library/ff728592.aspx

Azure Stock Trader

Sometimes you need a mix of a CodePlex-style application, and a little more detail on how it was put together. And it would be great if you could actually play with the completed application, to see how it really functions on the actual platform.

That’s the Azure Stock Trader application. There’s a place where you can read about the application, and then it’s been published to Windows Azure – the production platform – and you can use it, explore, and see how it performs.

I use this application all the time to demonstrate Windows Azure, or a particular part of Windows Azure.

The advantage is that this is an end-to-end application, and online as well. The disadvantage is that it takes a bit of self-learning to work through.

Book Review (Book 11) - Applied Architecture Patterns on the Microsoft Platform

BuckWoody — Tue, 15 May 2012 16:50:34 GMT

This is a continuation of the books I challenged myself to read to help my career - one a month, for year. You can read my first book review here, and the entire list is here. The book I chose for April 2012 was: Applied Architecture Patterns on the Microsoft Platform. I was traveling at the end of last month so I’m a bit late posting this review here.

Why I chose this book:

I actually know a few of the authors on this book, so when they told me about it I wanted to check it out. The premise of the book is exactly as it states in the title - to learn how to solve a problem using products from Microsoft.

What I learned:

I liked the book - a lot. They've arranged the content in a "Solution Decision Framework", that presents a few elements to help you identify a need and then propose alternate solutions to solve them, and then the rationale for the choice. But the payoff is that the authors then walk through the solution they implement and what they ran into doing it.

I really liked this approach. It's not a huge book, but one I've referred to again since I've read it. It's fairly comprehensive, and includes server-oriented products, not things like Microsoft Office or other client-side tools. In fact, I would LOVE to have a work like this for Open Source and other vendors as well - would make for a great library for a Systems Architect. This one is unashamedly aimed at the Microsoft products, and even if I didn't work here, I'd be fine with that. As I said, it would be interesting to see some books on other platforms like this, but I haven't run across something that presents other systems in quite this way.

And that brings up an interesting point - This book is aimed at folks who create solutions within an organization. It's not aimed at Administrators, DBA's, Developers or the like, although I think all of those audiences could benefit from reading it. The solutions are made up, and not to a huge level of depth - nor should they be. It's a great exercise in thinking these kinds of things through in a structured way.

The information is a bit dated, especially for Windows and SQL Azure. While the general concepts hold, the cloud platform from Microsoft is evolving so quickly that any printed book finds it hard to keep up with the improvements.

I do have one quibble with the text - the chapters are a bit uneven. This is always a danger with multiple authors, but it shows up in a couple of chapters. I winced at one of the chapters that tried to take a more conversational, humorous style. This kind of academic work doesn't lend itself to that style.

I recommend you get the book - and use it. I hope they keep it updated - I'll be a frequent customer. :)

Preparation is key to a successful cloud deployment

BuckWoody — Tue, 01 May 2012 13:09:16 GMT

If you want to be wise, watch the actions and outcomes of others. Emulate the successful actions, and avoid the actions that cause failure. That’s true in life in general - and in technology projects in specific.

I’ve worked with several clients who have created or migrated an application to “the cloud” - meaning using Microsoft Windows Azure or another provider. Although the statement in the title of this post is trite, I cannot over-emphasize how accurate it is. In every case of those who had a great experience with a distributed computing environment (which is thankfully the vast majority of my projects),

What kind of preparation do you need to do? Here are some tips I’ve learned in the successful (and not-so-successful) deployments I’ve seen:

Follow standard recommendations for successful projects in general

You and your organization have probably done a few projects before - this one should have the same general attributes: a well-defined goal, a small, motivated team, a realistic timeline, and an adequate budget. I know, I know, you *never* seem to get those things - but if you don’t, you’ll fail. Simple as that.

Educate yourself

Computing technology started out on a single set of hardware for a single purpose - and realizing the limits of the hardware at hand, systems designers quickly realized that scale-out and virtualization was key. No, that’s not new - mainframes almost always worked on the concept of scale-out and virtual machines. But we switched in the 1980’s to single-user systems again, and we’ve been there ever since. By that I mean you install an OS on the things you work on. Now we move back to distributed system concepts, and there are some real differences. You’ll need to learn how those work, and do things a new way. Hey, we’re IT - we LOVE learning new things, right?

Get a partner if needed

There are a few of us white-haired Gandalf’s around that remember how to work in a distributed system, but if it’s new to you, that’s completely OK. You can save yourself a world of trouble by working with someone who’s done this before - a partner you hire, someone from Microsoft Consulting, whatever.

And don’t forget support - who will handle each issue, what is the escalation model, who are your contacts at Microsoft, and what is your “light’s out” strategy?

“A new broom sweeps clean”, the old adage goes, but the old brooms know where the dirt is.

Build a model

Take some time to do a Proof of Concept on your local system and using your Azure hours from your MSDN account if you have one. Going through this build - and being willing to throw it away and try it a different way - is invaluable.

Test your theories

Three statisticians are walking in a field. They see a rabbit - the first guy raises his gun, firing far in front of the rabbit. The second guy simultaneously raises his gun and fires far behind the rabbit. The third guy yells “We got him!”

Not every theory is correct - not every attempt is the right one. Build in your success tests while you’re building your model. Then check them - don’t leave this step out.

Rinse, lather, repeat

This is advice from a shampoo bottle - which I’ve never used (I don’t really have that much hair - especially now). But in a “Cloud” project, it’s important. It’s an evolving system, that gains new improvements at an amazing rate. As soon as you deploy and stabilize you need to start the process over again. If you created your system in a Services model, with contracts for the APIs and abstracted code, this is far easier.

It’s not hard to do a cloud project right. But it’s really simple to do it wrong. Follow these guidelines and you’ll learn from the successes - and mistakes - of others.
