We have not decided if we are going to leave the EF in the 3.6 edition when we release, or if it will continue to be a Preview technology. It all depends on the feedback we get from the community.
The Entity Framework DLL implements all the commands, but we are not sure about all the various SQL generation strategies in the EF runtime. I am sure there are some LINQ commands that will generate terrible SQL for us, but we need to find those and get them addressed. I wanted to get a profile and stat output for this build, but it didn’t make it in – maybe next one. I think the EF basics should work for just about anything, it just remains to be seen how well it performs on various LINQ commands, and what we can do to improve it.
The current plan is to test EF for now as a Preview technology and ship it later this year. Is this feature a big enough deal to bump the version to 4.0? We would like to know your feedback. It has been a lot of work to get all of the EF implemented and tested, but hopefully it will show people that VistaDB is quite serious about the future of database technologies. People thought we hadn’t shipped it because we couldn’t do it for some reason. We are just taking a very cautious approach, hopefully that is something you can appreciate from your database vendor.
Last post I talked about how to get WPF data binding to work with master-detail entity collections. I had a couple readers ask me how they could filter the child collection instead of bringing them all down so in this post I’d like to show how you could do that. It’s actually pretty easy. …
LinqToSql data classes are not unit test friendly. To solve this, we can wrap the LinqToSql ‘ DataContext ‘ in a repository. The repository itself can be unit tested either by mocking up the functionality or by a stub TestRepository class. IRepository interface.
So I ran into an annoying problem today with an entity that has a timestamp. When imported LINQ to SQL will create a Binary type for this the timestamp and as it turns out this type does not serialize via XML. This means ASMX Web services fail as well as plain old XmlSerializer style serialization. You’ll get: System.Data.Linq.Binary cannot be serialized because it does not have a parameterless constructor. …
At Faculty Summit 2009 conference, Microsoft announced the availability of Dryad and the DryadLINQ programming tools. (The Dryad code is in binary form and DryadLINQ in source form). DryadLINQ makes the Language-Integrated Query (LINQ) extensions to the C# programming language available to .Net developers writing Dryad apps. Microsoft execs acknowledged that Dryad isn’t available on top of Azure (Microsoft’s cloud-computing platform), but that the plan is to make it available there.

The next few months are going to be exciting. On the technology front, we are getting ready for our next CTP in August. You can, however, get started today with SQL Express. The team has been working closely with some early adopters and the feedback has been overwhelming positive. Thank you for being so patient, the wait is almost over. Over the next day or two, we will be pushing additional details regarding SQL Azure, including posting our first round of SQL Azure Database documentation to MSDN (once it’s posted, I will post a link to it here).

• SunnyJC leaked to the Data Platform Insider blog that Microsoft SQL Services is now Microsoft SQL Azure and and SQL Data Services will become Microsoft SQL Azure Database. The link appeared on 7/8/2009 at about 9:30 AM PDT in the blog’s Atom feed but the post wasn’t accessible at 10:30 AM, so here’s the full text:
You are hearing it here first: Microsoft is updating the branding for SQL Services and SQL Data Services. Effective immediately, SQL Services will be called Microsoft SQL Azure, and SQL Data Services will be Microsoft SQL Azure Database. This name change doesn’t reflect a change in the products themselves; we will still be providing a powerful relational database foundation to the Azure Services Platform. By standardizing our naming conventions, we’re demonstrating the tight integration between the components of the services platform. More intuitive names also help to reinforce the relationships between our on-premises and cloud solutions. Ultimately, the goal is to drive simplicity and clarity for customers as they consider on-premises and cloud computing approaches for solving their IT needs.

For those of you not attending in person, all the news and information can be found at: http://www.digitalwpc.com/. Check back often starting next Monday, July 13, for daily updates.
• The SQL Data Services team’s TSQL Support in SQL Data Services post of 7/8/2009 describes the T-SQL restrictions imposed by SQL Server 2008’s implementation for Windows Azure as a hosted multi-tenant system. The post covers restrictions to DDL, DML and manageability features. (The team apparently didn’t have the word or the authority to use the new name.)
SQL runs good on Vsphere and does so mostly out of the box with little SQL Server specific tweaking. I hope to see some production apps running on Vsphere soon and will compare the real world results with the lab results. I am pretty hopeful a Vsphere\SQL Server combination is a good one. The ESX 3.5\SQL Server whitepaper did not show physical vs. virtual numbers so one would assume that they were not stellar.
The whitepaper should be of interest to potential SDS users.
••Wictor Wilén’s Use Windows Azure as your SharePoint Records Center post of 7/10/2009 describes how to create a Web Cloud Service called AzureRecordsCenter, generate an IRecordsRepositorySoap.cs file containing the correct interface for the records management web service, and add a new Web Service named OfficialFile.asmx that implements four methods:

Any solutions that currently rely on the Workflow Services will have to be modified on or before 7/7/2009 9am PST in order to continue functioning smoothly. Existing solution Workflow Service metadata such as Workflow Type will also be deleted and cannot be retrieved after the July 2009 CTP release. (…)”
Anyone using the .NET Service Bus should take a good look at the SocketShifter project started by Rob Blackwell and Richard Prodger from AWS in the UK. AWS stands for Active Web Solutions, not for the "other" AWS. The full project is up on Codeplex.
What makes SocketShifter significant is that it takes the network abstraction of SOAP, WS-Addressing, and the Service Bus full circle and layers the very bottom of that stack - plain TCP connections - as a virtualization on top of the the stack. In other words: SocketShifter allows you to create full-fidelity, bi-directional socket connections through the .NET Service Bus.
We've created something very similar to SocketShifter last year (we're using it for a few internal purposes), but haven't made it public so far. I'm glad that the AWS folks built this, so that you get to play with it.

•••Michael Stiefel “is back to talk about the realities of Cloud Computing including offerings from Amazon, Google, and Microsoft Azure” in .NET Rocks Show #459, Michael Stiefel on Cloud Computing, of 6/30/2009.
According to Carl and Richard:
Michael Stiefel, principal of Reliable Software, Inc., is a consultant on software architecture and development and the alignment of information technology with business goals. He is currently a member of the OASIS Technical Committee developing a core SOA Reference Model. He is a Visiting Scholar at Massachusetts Institute of Technology in the Science, Technology and Society Program where his research and teaching focus is the teaching of engineering to high school and undergraduate students. …
If Microsoft Azure services cost 10% less than comparable Amazon Web Services, the company could win converts to its camp despite its late start.
Microsoft has told some big customers that the 10% differential is part of a broad pricing plan for the services. Another source said Microsoft used both AWS and services like Go Daddy as reference points for price comparisons on the business and consumer side. "They talked about coming in at 5% or 10% below what's already out there," he said.
According to one corporate IT manager, Microsoft, for purposes of the price comparison, used the less expensive AWS Linux compute and storage services as the baseline. …
I believe it will take more than a 10% price break for Microsoft to entice AWS users to move to Azure. What’s missing is a competitive pricing analysis for the Google App Engine. Another open issue is how Azure’s SLA terms compare with AWS and GAE.

•• Randy Bias’ Cloud Futures Pt. 4: The Culling post of 7/9/2009 likens the coming natural selection of cloud-computing keepers with the “smoking crater” implosion of Internet startup ISPs and data centers (e.g., Exodus Communications). Randy writes:
… We’ve barely come out of the initial hype cycle (or perhaps we’re still deep in it) and there are quite a few small players in the space. More importantly, there are many small players looking to enter. At some point forcing functions will cause a major culling of the hosting and cloud computing industries, at least at the Infrastructure-as-a-Service (IaaS) layer, which is most susceptible to commodity pricing pressure.
I suspect the forcing functions will be twofold:
The telcos and large players will ‘wake up’ and use commercial products like VMware’s vCloud, Citrix Cloud Center (C3), VMops, or EUCALYPTUS to drive wide adoption
Serious consolidation will take place
Fights for market share will drive pricing pressure which will drive consolidation. During the consolidation process large and small businesses alike will see both opportunity and failure. If it’s anything like the original commercial Internet consolidation there will be a ‘great culling’ of all of the current and new players. Only the strong or savvy will survive.
Following are Randy’s earlier members of this series:
My bet is on the Azure Services Platform as a keeper if the team gets its SLA(s) and pricing right and doesn’t have significant downtime between now and Azure’s release to Web (RTW).
When clouds go global and services are shared across multiple time zones, perhaps that heralds the emergence of a new structure. Some have taken to calling this global confederation of services the “intercloud.”
Shades of the Internet, the network of networks. In a new post, Lori MacVittie provides a description of the intercloud:
“The intercloud is the natural evolution of global application delivery. The intercloud is about delivering applications (services) from one of many locations based on a variety of parameters that will be, one assumes, user/organization defined. Some of those parameters could be traditional ones: application availability, performance, or user-location. Others could be more business-focused and based on such tangibles as cost of processing.” …
I moderated a Cisco panel last week at Cisco Live! and it was readily apparent that enterprise cloud still required plenty of work from vendors and enterprise IT. No one was ready to endorse either a centralized or decentralized architecture (a move to the powerful intercloud); perhaps it’s because the network isn’t ready for infrastructure 2.0 demands.
• David Linthicum’s The Five Basic Characteristics of SOA post of 7/7/2009 contrasts Gartner’s "9 ways to measure SOA success” with his five “that are more specific to SOA.”
The ability to alter schemas without affecting services and/or processes.
The ability to alter services and/or processes, without altering schemas.
The ability to create and alter core business processes using a configuration rather than a programming approach.
The ability to leverage processes and services from outside of the enterprise, such as from a cloud computing provider.
The ability to expose processes and services from inside of the enterprise.
These are probably the three most important examples of how disagreement is driving technology road maps industrywide. Some of these disagreements are clearly self-serving--established systems vendors protecting their markets while enthusiastic entrepreneurs attempt to redefine the markets outright. Some are just different ways of seeing the same subject, but with profound effects on the choices made by vendors and individuals on each side of the debate:
Consumer and small/midsize business versus enterprise
Public cloud versus private cloud
Open source versus proprietary
His post expands on the three debates and says this (inter alia) about #3:
Folks like Microsoft and VMWare, however, would beg to differ and are working furiously to prove to the market that their value add is worth the cost of their software. The argument is that these companies can pay for innovation and for a partner ecosystem that drives new business and have the customer relationships to work through long-term cloud deployment issues.
At MIX ‘09 we (Microsoft) announced support for FastCGI in Windows Azure. FastCGI allows us to host applications like PHP both safely and performantly (warning – performantly is not a real word). In this post, I will begin with a very brief overview of what Windows Azure is and why you might consider hosting your PHP apps on Windows Azure. I will then provide you with a couple of resources that you can use to easily publish your PHP application to Windows Azure, including a link to a screencast I created that illustrates just how to publish a PHP application to Windows Azure.
I’m proud to announce our second milestone for the PHP SDK for Windows Azure project that Microsoft and RealDolmen started back in May. Next to our regular releases on CodePlex, we’ll also be shipping a Zend Framework version of the PHP SDK for Windows Azure. Announcements on this will be made later.
The current milestone is focused on Windows Azure Table Storage, enabling you to use all features this service offers from any PHP application, be it hosted in-premise or on Windows Azure.
Microsoft is planning to share details about its pricing and licensing plans for its Azure cloud environment at its Worldwide Partner Conference in mid-July. That’s what we know.

If you create a class library and add a reference to it from an Azure Web Role or Azure Worker Role you get an error. Here’s how to get around it.
The problem is that the class library template for Visual Studio 2010 creates a .csproj file with too few configuration settings. In Visual Studio 2008 the default target platform is AnyCPU. In Visual Studio 2010 it’s x86 and the configuration for AnyCPU is not included. It seems to me this is an error in Visual Studio 2010 Beta 1.
Research firm IDC predicts that the worldwide cloud services market segment will be worth about US$43 billion by 2012.

••• Elinor Mills reports Prosecutor: Cloud computing is security's frontier in this 7/10/2009 post for CNet News. The prosecutor in question is Matthew Parrella, an assistant U.S. attorney based in San Jose, Calif. who spoke at Symantec's Norton Cyber Crime Day:
… Looking ahead five years, "I'm thinking the attack is going to be on cloud computing centers," said Parrella, chief of the computer hacking and intellectual property unit at the U.S. Attorney's Office.
The immediate threat will be attacks to steal data from the servers they are stored on, either remotely or by an insider or someone who gains access to the data center, he said. Later on it's likely any stolen data could be pirated, he said. …
… Starting over the Independence Day weekend and continuing into the week, hackers targeted government and business websites in the United States and South Korea, causing varying degrees of disruption of service. Among federal government websites reportedly assaulted: the White House, National Security Agency, Departments of Defense, Homeland Security, State and Transportation and Treasury; Federal Trade Commission and the Secret Service. Among business sites said to have been attacked: the New York Stock Exchange, NASDAQ and The Washington Post. …
Ferris recently had a briefing from Microsoft on the security of its Business Process Online Services (BPOS) — e.g., Exchange Online, SharePoint Online, etc. This presentation turned out to be of more interest to Ferris for its subtext than for the specifics it contained.
The subtext was that Microsoft was encountering concern (pushback?) from organizations about both the security of data held in Microsoft Online services, and the security of the services themselves. Stated another way, organizations appear to want to apply the same analysis to cloud-delivered services that they apply to on-premise-delivered services. We cannot believe that these concerns are unique to Microsoft, and are therefore an issue that will have to be addressed by all providers of cloud-based services and associated cloud-based data storage. …
Is the Cloud Secure? That’s a silly question. Is the Cloud “secure enough” is really the question that should be asked, and of course, the answer is entirely contextual.
Cloud will reach a critical mass wherein the technology and operational models mature to a good-enough point, enough time passes without a significant number of material breaches or outages that disrupt confidence and then it becomes “accepted.” Security, based upon how, where, why and when we invest will always play catch-up. How much depends on how good a job we do to push the agenda.
• Satyajit Grover, Xiaozhu Kang, Michael Kounavis and Frank Berry describe “New technologies that show the economy of using general-purpose hardware for high-volume HTTPS traffic” in this Intel white paper, Encrypting the Internet, of 7/1/2009 for Dr. Dobbs Journal. Section 2 The Advanced Encryption Standard and the RSA Algorithm, describes in detail how AES and RSA work in the SSL/TLS environment.
At this point, it might be ludicrous for anyone to put their most sensitve data in the cloud as a security measure. But the dire straits at the National Archives should stand as a warning for those who think traditional data security measures are without vulnerability.
Not as ludicrous as letting employees walk out with hard drives and servers.
• Philip Richardson of Microsoft chimes in on the same topic with his It’s Hard to Steal a Cloud post of 7/6/2009:
As this short article on ReadWriteWeb puts it: “It’s Hard to Steal A Cloud”. The US National Archives has lost some hard drives and would like them back. It’s important to remember a couple of things: a) lost != stolen and b) stolen usually == copied.
Sure the Cloud takes away the need for worrying about a lot of physical devices (physical security, transport, power, storage conditions etc). However it does place additional focus on Authorization to the Cloud Data. This set of apocryphal credentials are now the ‘keys to the kingdom’ – as opposed to root domain access and/or physical data center access. At lot of organizations as they move to the Cloud and going to have to get very serious about how they store and distribute these credentials.
It’s important for enterprises to look at the Cloud from an ‘emotionless’ position. The ridiculous superstition of ‘on premise is more secure’ needs to be replaced with more mature analysis of short, medium and long term threats (and cost modeling).

•••Anil Dash delivers a lengthy essay on Google’s metamorphosis in his Google's Microsoft Moment post of 7/9/2009, which begins:
I'm not sure Google's new Chrome OS announcement is that big a deal, or that the eventual product that gets released will actually have that much impact, but it's a useful milestone in marking Google's evolution towards becoming an older company with a distinctly different culture than they used to have.
This is, for lack of a better term, Google's "Microsoft Moment". This is the point when the difference between their internal conception of the company starts to diverge just a bit too far from the public perception of the company, and even starts to diverge from reality. At this inflection point, the reasons for doing new things at Google start to change. [Anil’s emphasis.] …
This talk describes the constraints of connected systems design and presents common design patterns to address some of the challenges developers will face as they spend more time connecting services and components instead of developing new ones. Along the way he asks: Is coupling really so bad? Why is REST popular? Do we need distributed transactions?

•• John Treadway reports he was struck with the “coherence and clarity of their cloud computing vision as compared to HP or IBM” in his Unisys – A Clear Vision for the Cloud post of 7/10/2009:
Unisys’ strategy bridges public, private and hybrid cloud models, and includes well-differentiated infrastructure, platform and software as a service offerings (IaaS, PaaS, and SaaS). Further, they wrap this all in a set of comprehensive service offerings that they can deliver globally. It’s a big vision, and if they can pull it off it should make them one of the more interesting providers out there. One of their key differentiators is Unisys Stealth (described [in John’s post]).
•• Chris Beckman’s Information regarding 2 July 2009 outage post of 7/8/2009 post to the Google App Engine Forum seeks to explain the circumstances of the 12-hour (6:45 AM to 12:35 PM) GAE outage on 7/2/2009:
The App Engine outage was due to complete unavailability of the datacenter's persistence layer, GFS, for approximately three hours. The GFS failure was abrupt for reasons described below, and as a consequence the data belonging to App Engine applications remained resident on GFS servers and was unreachable during this period. Since needed application data was completely unreachable for a longer than expected time period, we could not follow the usual procedure of serving of App Engine applications from an alternate datacenter, because doing so would have resulted in inconsistent or unavailable data for applications.
The root cause of the outage was a bug in the GFS Master server caused by another client in the datacenter sending it an improperly formed filehandle which had not been safely sanitized on the server side, and thus caused a stack overflow on the Master when processed.
The inability to “follow the usual procedure of serving of App Engine applications from an alternate datacenter, because doing so would have resulted in inconsistent or unavailable data for applications” is an inexcusable single point of failure. Inability to autorecover from what sounds like a readily anticipated stack overflow is another indication of a serious engineering oversight.
… I spoke to [Microsoft Vice President of Developer and Platform Evangelism] Abu-Hadba at a dinner in San Francisco to promote tomorrow’s launch of Silverlight 3, the latest version of Microsoft’s platform for web media and applications. Some of his remarks about Chrome consisted of entertaining bluster: “I love competition.” But he also had thoughts about why Google is trying to muscle into the operating system business. And no, he said, it’s not because Google wants to make computing simpler and faster (as Google executives claim), nor is it part of a grand plan to undo Microsoft’s dominance (as VentureBeat writer Dean Takahashi speculated). …
“Most of what Google does is defensive,” Abu-Hadba said.
•• M. Koenig and C. Burns authored Google Chrome OS: Opening a New Front in the Browser Wars on 7/9/2009 as a Saugatuck Research Alert (free site registration required). Their dispassionate and detailed analysis of Chrome OS is a welcome relief from the breathless reportage of some “social sites.”
What surprises me is the missing Google App Engine in this Saugatuck table that compares the Microsoft and Google Stacks [color emphasis added]:
Layer
Microsoft
Google
Office Productivity & Collaboration
Office, Office Live and Sharepoint
Google Apps, Gmail, Google Wave
Browser
Internet Explorer
Google Chrome
Desktop OS
WindowsVista and Windows &
Google Chrome OS
Mobile OS
Windows Mobile
Google Android
Server OS
Windows Server
Google ???
Cloud OS
Microsoft Azure
Google ???
If the Saugatuck authors include Gmail in the Googstack, certainly Microsoft Exchange belongs in the MsftStack. I assume that Windows & = Windows 7 (as the result of a spurious Caps key press.)
I agree wholeheartedly with the authors’ Market Impact conclusion.
Google has caught Microsoft napping in this new battleground but now that it has awakened the Redmond Giant to the threat, it has to execute sharply or this Giant and other competitors will feast on its dying carcass. It isn’t looking good. Google appears unfocused, uncoordinated, it has no apparent marketing or PR skills, and it will likely be over a year before the finished product can even enter the market. All this time it will probably be bleeding search market share as Microsoft and others take advantage of Google’s lack of focus and Microsoft prepares its second strike response.
I continue to see this related to an education system that seems to teach that going through the motions is the same thing as accomplishing the task, and the historic problem of managers being better at setting expectations than they are at setting appropriate goals and achieving them. There is a way to do this right. Google is not currently on that path.
Database giant Oracle Corp. has stopped work on a $313 million data center in Utah.
The Salt Lake Tribune reported Tuesday that Oracle (NASDAQ: ORCL) quietly stopped construction on the center, in West Jordan, near the Salt Lake City Municipal Airport, three months ago. The halt is linked to Oracle’s planned acquisition of Sun Microsystems (NASDAQ: JAVA), the paper said.
Oracle sold $4.5 billion in debt this week to raise cash for that acquisition.
Construction started last summer on what Oracle called “Project Sequoia.” It was meant as a showcase “green data center” with “dramatically lower energy consumption,” Oracle said at the time.
To recap, over a year ago I described the opportunity for what I called a Virtual Private Cloud or a method for partitioning a public computing utility such as EC2 into quarantined virtual infrastructure. A VPC may encapsulate multiple local and remote resources to appear as a single homogeneous computing environment bridging the ability to securely utilize remote resources as part of an seamless global compute infrastructure.
• Sundar Pichai’s Introducing the Google Chrome OS vaporware post of 7/7/2009 describes a forthcoming “new project that's a natural extension of Google Chrome — the Google Chrome Operating System. It's our attempt to re-think what operating systems should be.”
Google Chrome OS is an open source, lightweight operating system that will initially be targeted at netbooks. Later this year we will open-source its code, and netbooks running Google Chrome OS will be available for consumers in the second half of 2010.
Instead of doing their own OS, they could have rallied behind one of the Linux distros, say Damn Small Linux, and helped them get traction among the hardware vendors. This is a move by Google to deflect the high handed tactics by Microsoft in the netbook market but it appears to me like a redundant one. I feel that they should have supported one of the existing distros. However, if they had taken that route, there is no way they could have pushed the Google Chrome browser (and their services) tightly integrated with the Linux distro. In short, it is a desperate attempt by Google to stop Microsoft in the netbook game and, also, push the Google Chrome browser to the masses at a point in time when IE’s market share is going downhill.
Twilio is a remarkably simple concept, but very difficult to implement in an elegant way, as the Twilio folks have done. It is a cloud platform that enables developers with basic web programming skills to develop complex voice applications.
Under the hood -- but completely transparent to the developer or the end user -- Twilio is hosted on Amazon EC2, uses a multi-tenant architecture and has implemented a fully functional telephony infrastructure based on the open source framework Asterisk.
• Dan Woods asks “Will the company need to clean up its applications to change the face of cloud computing?” in his Questioning Oracle's Cloud article of 7/7/2009 for Forbes.com:
When Larry Ellison announced last month that Oracle was going to embrace cloud computing, he put forth ideas that expand on the current models. With the Sun acquisition and the rest of its formidable portfolio, Oracle has all the pieces of the puzzle to do something revolutionary. The key question: Will Oracle have to clean up its fragmented collection of applications to achieve its vision?

Cisco's CTO says the company will set itself apart by helping enterprises move resources among internal and external clouds instead of becoming a pay-as-you-go cloud provider.
The company sees virtualization as the next major computing model and its own Unified Computing System (UCS) as the first step toward a fully virtualized data center, CTO Padmasree Warrior said in a briefing Monday during the Cisco Live user conference in San Francisco. The company's presence in both enterprise and service provider networks makes it the ideal partner for companies adopting cloud computing, because they want to gain cloud benefits like scalability and disaster recovery without pushing out control of all their infrastructure, she said.
