[New England] Mark Souza on Big Data and Cloud at NESQL

Adam Machanic — Sun, 13 Jan 2013 18:33:00 GMT

This Thursday, January 17, at New England SQL Server we'll be featuring Mark Souza, General Manager of the Data Platform Group at Microsoft. Most of you are probably familiar with that name; he's the guy who founded the CAT team, and he's been in a number of key roles in the SQL Server organization for the past several years.

Mark's topic for Thursday is Big Data and Cloud at Microsoft. The talk should be an interesting look into how the company is approaching these key areas.

If you're in New England and aren't already a member of New England SQL Server, you can sign up here. RSVP is required to attend our meetings, and we will send out the invitation e-mail on Tuesday morning.

Hope to see many of you there!

Declarative Architectures in Infrastructure as a Service (IaaS)

BuckWoody — Tue, 23 Oct 2012 14:00:00 GMT

I deal with computing architectures by first laying out requirements, and then laying in any constraints for it's success. Only then do I bring in computing elements to apply to the system. As an example, a requirement might be "world-side availability" and a constraint might be "with less than 80ms response time and full HA" or something similar. Then I can choose from the best fit of technologies which range from full-up on-premises computing to IaaS, PaaS or SaaS.

I also deal in abstraction layers - on-premises systems are fully under your control, in IaaS the hardware is abstracted (but not the OS, scale, runtimes and so on), in PaaS the hardware and the OS is abstracted and you focus on code and data only, and in SaaS everything is abstracted - you merely purchase the function you want (like an e-mail server or some such) and simply use it.

When you think about solutions this way, the architecture moves to the primary factor in your decision. It's problem-first architecting, and then laying in whatever technology or vendor best fixes the problem.

To that end, most architects design a solution using a graphical tool (I use Visio) and then creating documents that let the rest of the team (and business) know what is required. It's the template, or recipe, for the solution. This is extremely easy to do for SaaS - you merely point out what the needs are, research the vendor and present the findings (and bill) to the business. IT might not even be involved there. In PaaS it's not much more complicated - you use the same Application Lifecycle Management and design tools you always have for code, such as Visual Studio or some other process and toolset, and you can "stamp out" the application in multiple locations, update it and so on.

IaaS is another story. Here you have multiple machines, operating systems, patches, virus scanning, run-times, scale-patterns and tools and much more that you have to deal with, since essentially it's just an in-house system being hosted by someone else. You can certainly automate builds of servers - we do this as technical professionals every day. From Windows to Linux, it's simple enough to create a "build script" that makes a system just like the one we made yesterday. What is more problematic is being able to tie those systems together in a coherent way (as a solution) and then stamp that out repeatedly, especially when you might want to deploy that solution on-premises, or in one cloud vendor or another.

Lately I've been working with a company called RightScale that does exactly this. I'll point you to their site for more info, but the general idea is that you document out your intent for a set of servers, and it will deploy them to on-premises private clouds, Windows Azure, and other public cloud providers all from the same script. In other words, it doesn't contain the images or anything like that - it contains the scripts to build them on-premises in private clouds or on a public cloud vendor like Microsoft.

Using a tool like this, you combine the steps of designing a system (all the way down to passwords and accounts if you wish) and then the document drives the distribution and implementation of that intent. As time goes on and more and more companies implement solutions on various providers (perhaps for HA and DR) then this becomes a compelling investigation.

The RightScale information is here, if you want to investigate it further. Yes, there are other methods I've found, but most are tied to a single kind of cloud, and I'm not into vendor lock-in.

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

Hadoop growing pains

rodak.p@gmail.com — Thu, 21 Jun 2012 20:45:56 GMT

This post is not going to be about SQL Server. I have been reading recently more and more about “Big Data” – very catchy term that describes untamed increase of the data that mankind is producing each day and the struggle to capture the meaning of these data. Ten years ago, and perhaps even three years ago this need was not so recognized. Increasing number of smartphones and discernable trend of mainstream Internet traffic moving to the smartphone generated one means that there is bigger and bigger stream of information that has to be stored, transformed, analysed and perhaps monetized. The nature of this traffic makes if very difficult to wrap it into boundaries of relational database engines. The amount of data makes it near to impossible to process them in relational databases within reasonable time. This is where ‘cloud’ technologies come to play.

I just read a good article about the growing pains of Hadoop, which became one of the leading players on distributed processing arena within last year or two. Toby Baer concludes in it that lack of enterprise ready toolsets hinders Hadoop’s apprehension in the enterprise world. While this is true, something else drew my attention. According to the article there are already about half of a dozen of commercially supported distributions of Hadoop. For me, who has not been involved into intricacies of open-source world, this is quite interesting observation. On one hand, it is good that there is competition as it is beneficial in the end to the customer. On the other hand, the customer is faced with difficulty of choosing the right distribution. In future, when Hadoop distributions fork even more, this choice will be even harder. The distributions will have overlapping sets of features, yet will be quite incompatible with each other. I suppose it will take a few years until leaders emerge and the market will begin to resemble what we see in Linux world. There are myriads of distributions, but only few are acknowledged by the industry as enterprise standard. Others are honed by bearded individuals with too much time to spend.

In any way, the third fact I can’t help but notice about the proliferation of distributions of Hadoop is that IT professionals will have jobs.

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/
