Microsoft extends Azure Hadoop, mobile app development functionality

An HDInsight addition lets users deploy, manage and use Hadoop clusters on Microsoft's cloud

Microsoft has released a number of enhancements to Windows Azure that will make it easier to deploy and manage Hadoop clusters and integrate more mobile apps with the cloud platform.

To simplify the roll out of big data applications, Microsoft is offering a public preview of the new HDInsight service for Windows Azure, according to Scott Guthrie, corporate vice president in Microsoft's Server and Tools Business. HDInsight lets users deploy, manage and use Hadoop clusters running on Windows Azure, he saidin a blog post.

Users with a Windows Azure account can request access to the preview and once that has been granted create a cluster from within the Windows Azure Management Portal. A storage account is also required and in the current version of the preview it must reside in the East U.S. region, according to Guthrie.

A new installation will take a few minutes to create and as part of the process users need to configure the necessary virtual machines that will make up their Hadoop cluster, Guthrie said.

From the management console users can then click on "create job" to open a MapReduce job submission form. There is also an "interactive console" tile that lets users execute Javascript and Hive queries directly against their cluster.

The latter provides a means of running a MapReduce job through a SQL-like scripting called HiveQL, which can be used to summarize, query and analyze large volumes of data.

The Hadoop distribution in Windows Azure HDInsight is for now based on the Hortonworks Data Platform 1.1.

For mobile app developers, Microsoft added the ability for pure HTML5 and Cordova/PhoneGap apps as well as Windows Phone 7.5 clients to use Windows Azure for both data storage and authentication.

The first part is possible thanks to a new Mobile Services Web client library that in addition to Internet Explorer is compatible with current versions of Chrome, Firefox, Safari and PhoneGap 2.3 or later. The library has the same data querying and storage API support Microsoft offers in other native SDKs and allows user authentication via a Microsoft Account, Google, Facebook or Twitter.

The support for Windows Phone 7.5 is offered as a part of Microsoft consolidating its Windows 8 and Windows Phone 8 clients on top of a single codebase using Portable Libraries, which have been designed for use on multiple platforms.

Microsoft has step-by-step widened Azure's mobile platform support outside of its own operating systems, starting with iOS and then two weeks ago Android was added with the arrival of the new Android SDK for Windows Azure Mobile Services, which is available on GitHub under the Apache 2.0 license

Microsoft is also providing Dropbox integration. A Developer can now copy source files to the Dropbox sub-folder on their computer and press the "sync" button in the Windows Azure portal to deploy them. Windows Azure will automatically build sources as needed, according to Guthrie.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
