•• Jim Nakashima provides a more detailed description than Gus for Debugging Silverlight in a Web Role on the Development Fabric in this 1/16/2009 fully illustrated post.
•• Gus Perez explains how to enable Silverlight debugging with the January 2009 CTP of the Windows Azure SDK and Tools for VS 2008 in his Silverlight Debugging in Windows Azure Web Roles post of 1/16/2009. Silverlight debugging isn’t turned on by default, so here’s how to do it in Gus’s words:
- In the Solution Explorer, right-click the Web role project node that has the Silverlight code.
- Click on "Properties."
- Click on the "Web" tab.
- Towards the bottom, you'll find a "Debuggers" section (you may have to scroll down).
- Click on the "Silverlight" checkbox.
• The Windows Azure team’s Updated SDK and Tools for Visual Studio Available Now post of 1/14/2009 announces a refresh to the Windows Azure SDK and Windows Azure tools for Visual Studio.
- Download Windows Azure SDK January 2009 CTP (v. 184.108.40.206 of 1/14/2009)
- Download Windows Azure Tools for Visual Studio 2008 January 2009 CTP (v. 1.0 of 1/14/2009)
According to the Azure team’s post, the new CTP offers:
- Improved integration with Visual Studio
- Performance improvements with execution and debugging scenarios
- Improvements to Storage Client and ASP.Net provider samples
- Added support to debug Silverlight in a web role
- Bug and performance fixes based on customer feedback
Windows 7 Update 1/16/2009: David Lemphers reports in his Windows Azure SDK on Windows 7 Beta! post of 1/16/2009 that this SDK is incompatible with the current Windows 7 beta and there is no workaround available. The lack of incompatibility with the Azure Tools for VS 2008 is of little consequence if you can’t run the local Developer Fabric.
Read more about the CTP in my January 2009 Update to Windows Azure SDK and Visual Studio Tools CTPs Available for Download post and Jim Nakashima’s January 2009 CTP of the Windows Azure Tools and SDK released post of 1/15/2009.
•• Dare Obasanjo’s Building Scalable Databases: Pros and Cons of Various Database Sharding Schemes post of 1/16/2009 describes how scaling out by partitioning tables often is a better approach than scaling up by increasing the relational database management system’s (RDBS’s) computing power and input/output efficiency. SDS manages sharding with Kind field and Azure Table Services uses Partition Key values. All entities (rows) having the same Type or Partition Key value are stored in the same RDBMS or Windows Azure instance.
•• Mike Amundsen comes up with a use for SDS’s new non-traditional JOIN feature in his SDS JOINS: i got one that works! post of 1/15/2009. Mike notes that:
JOINdoes not support projection (basically the ability to select fields for display from either table/collection in the
JOIN). [I]nstead, you simply indicate which collection you wish SDS servers to return.
Azure Table Services doesn’t support claim to support JOINs, but you can return a collection that corresponds to the many side of a one:many or many:one association with the same WHERE clause restriction used by the JOIN’s ON clause constraint.
Mike’s example consists of three collections (tables): messages, words and indexes; indexes is a list of unique words in all messages. He “wanted to be able to use any member of the index collection to find all the messages that contained the word in the selected index entity.” And found a
JOIN would do it.
• Scott Watermasysk will present the “Developing Applications Using Microsoft SQL Data Services” session at the NYC edition of the MSDN DevCon, which will focus on leveraging data services both remotely and with SDS:
In the near future, applications will be developed using a combination of custom application code and online building block services, including data-centric services. In this session we discuss advancements in the Microsoft development platform and online service interfaces to enable seamless interaction with data services both on-premises (e.g., ADO.NET Data Services Framework over on-premises SQL Server) and in the cloud (e.g., SQL Server Data Services). Learn how you can leverage existing know-how related to LINQ (Language Integrated Query), data access APIs, data-binding, and more when building applications using online data.
According to Scott’s MSDN DevCon – NYC post of 1/14/2009, the session will be held at 2:00 to 3:15 PM on 1/20/2009 at:
Marriott Marquis New York
1535 Broadway (Times Square)
New York, NY 10036
and you can register here for $99. Other Azure-related sessions earlier in the day include “A Lap Around Windows Azure and the Azure Services Platform”, “Developing and Deploying Your First Azure Service” and “A Lap Around the Live Framework and Mesh Services.”
•• Aaron Skonnard’s Microsoft .NET Services Whitepapers by Pluralsight post of 1/16/2009 describes a series of whitepapers that Keith Brown, Matt Milner, and he recently wrote for Microsoft about their new .NET Services offering, which is part of the Azure Services Platform.

• Sergei Meleshchuk has fixed his Azure Storage Simple Viewer so it installs and runs under 32-bit Vista:
• Rick Strahl explains Monitoring HTTP Output with Fiddler in .NET HTTP Clients and WCF Proxies as well as with Fiddler alternative Charles in this 1/14/2009 post. You can use Fiddler2 to monitor traffic between an Azure Data Services client running in the local Development Fabric and Azure Table, Blob and/or Queue Services running on Staging or Production instances in the cloud. Rick says:
For plain Web development most of the time I actually use FireBug inside of FireFox, but when more detailed HTTP wire debugging is required I quickly revert to Fiddler, because it tends to provide more information and options on dealing with request data. But even more importantly, FireBug – cool and useful as it is as the Swiss Army knife for Web development debugging - is limited to life inside of FireFox, so it does nada when you need to look at content outside of the browser such as when a .NET application fires HTTP requests against a server.
David Pallman’s Azure Cloud Computing User Group - New Web Site post of 1/13/2009 announces that the master Azure user group has moved to http://www.AzureUserGroup.com (hosted by Ning). There were 11 members when I joined on 1/13/2008 at 11:00 AM.
Alin Irimie’s Weekly Cloud Application: Wikipedia Explorer post of 1/12/2009 describes Dot Net Solutions’ new version of its Wikipedia Explorer, which is built on top of Windows Azure. The project, which was built in partnership with Microsoft’s Developer and Platform Evangelism team, runs on a snapshot of Wikipedia’s entire English database that took 50 Azure server instances “a little over four days” to reformat from wikicode to XAML. [Copied from Azure and Cloud Computing Posts for 1/5/2009+.]
Azure Storage Explorer has been updated. Binaries and source code to "preview version 0.2" have been posted on CodePlex. This update adds some polish, has cleaned-up source code, and allows items in cloud storage to be deleted.
OakLeaf’s Azure Storage Services - StorageClient Library: Table Storage API Class Reference post of 1/7/2009 includes class diagrams for TableStorage, TableStorageDataServiceContext, TableStorageDataQuery and other .NET types with which developers must conversant to take full advantage of Azure Table and Blob Storage services.
The post has bee updated to include diagrams similar to class diagrams for the Details of TableStorage, TableStorage.DataServiceContext and TableStorage.DataServiceQuery classes from the System.Data.Services.Client namespace. Data for members of these classes was extracted with .NET Reflector.

James Urquhart’s Workload mobility and the next Internet upgrade post of 1/16/2009 discusses the issue of Internet bandwidth requirement for moving compute workloads between Platform as a Service (PaaS) instances hosted on the internet.
[T]here will be a heck of a lot of data moving between servers, between data centers, and with cloud computing from enterprises to service providers.
Doug’s A look ahead: Some technology developments to expect in 2009 CTOvision post of 1/1/2009 expects large-scale migration to cloud computing by federal agencies.
•• Krishnan Subramanian begins a new Cloud Advantage series on Cloud Avenue with Cloud Advantage Series: Speed of Deployment of 1/16/2009. Krishnan argues:
One of the advantages I put forward in support of the On-Demand cloud based infrastructure is the speed with which one can deploy new computing resources. In the traditional On-Premise world, the whole process from the planning stage to the actual deployment will take anything from few weeks to few months depending on the need.
and cites InformationWeek’s Eli Lilly On What's Next In Cloud Computing Webcast (from the “Other Cloud Computing Platforms and Services” section) as an example of a large-scale on-demand deployment by a large pharmaceuticals company.
•• David Linthicum’s Defining the Cloud Computing Framework post of 1/15/2009 for the Cloud Computing Journal begins:
As cloud computing emerges there is a lot of discussion about how to define cloud computing as a computing model. Maturity models have been published and debated, and providers clearly have a model for their own products.
In attempting to define this better to my clients, I came up with a "stack" of sorts, which I think makes logical sense, considering each component of cloud computing and how they interact. While clearly this could be much more complex, I don't think it needs to be. In essence, this is a model as to how one defines and refines the concept of cloud computing
and then lists 10 Whatever-as-a-Service items as major categories of cloud computing.
•• Aaron Skonnard is interviewed by developer evangelists Lynn Langit and Lindsay Rutter for his geekSpeak recording - Cloud Services 101 with Aaron Skonnard podcast of 1/7/2009. According to Channel9’s description:

•• Maureen O’Gara reports Google’s attempt to build a reseller channel for Google Apps in her Google Apps Resale “Easy Intro” to Cloud Computing post of 1/17/2009 to the Cloud Computing Journal. Resellers, such as Cloud Sherpa, receive a 20% discount on the $50 per year charge for premium services, which are targeted at corporate users.
To discourage free Google Apps usage by corporate accounts, O’Gara note that:
[F]rom here on out Google will limit the use of its freebie version of the software to 50 people per company. Current users, schools and non-profits will be exempt [from the limit].
[O]ptimize data center resources by capturing the object code of applications, pooling servers, and distributing workloads based on IT policies. It's not the same thing as virtualization, though virtual machines are involved. [Cassatt CEO Bill] Coleman says Cassatt can help IT departments get server utilization into the 80% range, compared with 20% to 40% when just virtualization is employed.
Creating private clouds in terrestrial data centers involves multi-million dollar investments, so Foley asks “How many small and medium-sized businesses can afford to deploy private clouds (Cassatt calls them internal clouds) at those prices? Answer: none.”
• Roger Smith describes how Engine Yard extended the company’s Ruby and Rails stack to run on Amazon Web Services, in addition to its own internal cloud, in his Engine Yard Switches Rails To Mainline Cloud article of 1/14/2009 for InformationWeek’s Analytics blog.
• Michael Fitzgerald’s Technology: When the Forecast Calls for Clouds article for Inc. magazine’s January 2009 issue offers two case studies for Amazon EC3:
- FlyMiwok, a Southern California on-demand charter flight reservation service handles large traffic surges.
- TC3 Health's cost containment software periodically checks millions of records for fraudulent or duplicate health insurance claims.
Last fall, over the course of a few weeks, Amazon moved its Elastic Compute Cloud, or EC2, service from beta testing into full production; Salesforce.com announced it would expand its cloud-computing platform; and Microsoft unveiled its cloud operating system, Windows Azure.
Microsoft's foray into the market is of particular note, because it's a big shift for the world's dominant traditional software company. "That Microsoft has wholeheartedly embraced the cloud is an indication that it's here," says Dave Girouard, president of Google Enterprise.
• Bill Staples describes How to Run Windows  & IIS [6.0] in the Cloud on Amazon EC2 (in 15 mins) in a lengthy, fully illustrated post of 1/13/2009.

• John Foley describes InformationWeek’s Eli Lilly On What's Next In Cloud Computing Webcast in this 1/14/2009 post:
In late 2007, [Lilly associate information consultant David Powers] said, the mindset among Eli Lilly's IT team was to take a wait-and-see approach to the emerging cloud services model. By early 2008, however, pressure was growing to reduce fixed IT costs without compromising on IT services, and cloud computing proved to be the answer.
Eli Lilly uses Amazon Web Services and other cloud services to provide high-performance computing, as needed, to hundreds of its scientists. With AWS, Powers said, a new server can be up and running in three minutes (it used to take Eli Lilly seven and a half weeks to deploy a server internally) and a 64-node Linux cluster can be online in five minutes (compared with three months internally). "The deployment time is really what impressed us," Powers said. "It's just shy of instantaneous." …
To hear more about what Eli Lilly is doing with cloud computing and where it goes from here, log in to our recent Webcast, which is available for replay. In addition to Dave, I give an overview of cloud services in the Webcast, and Amazon VP Adam Selipsky describes Amazon Web Services. You can sign in here

Evans Data’s claim that Half of Developers to Develop SaaS Software in Next Year was reported in Cloud Computing Journal’s 1/13/2009 issue:
According to the latest Evans Data Global Development Survey, over half of all developers (51.9% averaged over all regions) expect to work on programs delivered in the SaaS model during the next 12 months.
Adoption expectation is strongest in the Asia-Pacific region, although the number of developers currently working on SaaS implementations is highest in North America, where 30% say this is part of their current development efforts.
In the EMEA region, fewer developers are currently developing SaaS but 53% expect to be doing so within 12 months.
