Microsoft’s Azure outage: a troubling account of what went wrong

Microsoft’s Jason Zander has published an account of what went wrong yesterday, causing failure of many Azure services for a number of hours. The incident is described as running from 0.51 AM to 11.45 AM on November 19th though the actual length of the outage varied; an Azure application which I developed was offline for

An Azure Web Site is a VM which supports multiple applications

This will be unnecessary for Azure experts, but I have seen some misunderstanding on this point, hence this post.

A “web site” is a unit of service on the Azure cloud platform which represents a web application hosted on IIS, Microsoft’s web server (but see below). You write a standard ASP.NET application and deploy it.

Microsoft financials show robust performance, Office in transition to subscription, both cloud and server growth

Microsoft released its financial results yesterday, for the quarter ending September 30th 2014. It was a good quarter in most respects, though consumer Windows and Windows Phone licensing are weak.

Good news outweighs bad though, particularly the company’s success in transitioning Office customers from perpetual licences to subscription, even in the consumer market. It also

Xamarin Evolve: developers enjoy the buzz around cross-platform coding with C#

“It’s like a Microsoft developer event back when they were good,” one exhibitor here at Xamarin Evolve in Atlanta told me, and I do see what he means. There is plenty of buzz, since Xamarin is just three years old as a company and growing fast; there is the sense of an emerging technology, and

Microsoft Azure: new preview portal is “designed like an operating system” but is it better?

How important is the Azure portal, the web-based user interface for managing Microsoft’s cloud computing platform? You can argue that it is not all that important. Developers and users care more about the performance and reliability of the services themselves. You can also control Azure services through PowerShell scripts.

My view is the opposite though.

A note on Azure storage and downloading large files

I have written a simple ASP.NET MVC application for upload and download of files to/from Azure storage.

Getting large file upload to work was the first exercise, described here. That is working well; but what about download?

If your files in Azure storage are public, you can simply serve an URL to the file. If

Microsoft StorSimple brings hybrid cloud storage to the enterprise, but what about the rest of us?

Microsoft has released details of its StorSimple 8000 Series, the first major new release since it acquired the hybrid cloud storage appliance business back in late 2012.

I first came across StorSimple at what proved to be the last MMS (Microsoft Management Summit) event last year. The concept is brilliant: present the network with
