Uptime Report for my Live OakLeaf Systems Azure Table Services Sample Project: August 2013 = 100.00%

image_thumb13_thumbMy (@rogerjenn) live OakLeaf Systems Azure Table Services Sample Project demo project runs two small Windows Azure Web role compute instances from Microsoft’s South Central US (San Antonio, TX) data center. This report now contains more than two full years of uptime data.

I have no explanation for the 2 ms. difference between overall and detailed average response time.

The six-month string of 100% uptime came to an end on 9/42013.


This is the twenty-seventh uptime report for the two-Web role version of the sample project since it was upgraded to two instances. Uptimes below SLA 99.9% minimums are emphasized. Reports will continue on a monthly basis.

The Azure Table Services Sample Project

See my Republished My Live Azure Table Storage Paging Demo App with Two Small Instances and Connect, RDP post of 5/9/2011 for more details about the Windows Azure test harness instance.

imageI believe this project is the oldest continuously running Windows Azure application. I first deployed it in November 2008 when I was writing Cloud Computing with the Windows Azure Platform for Wiley/WROX, which was the first book published about Windows Azure.

imageThe application runs the default set of Windows Azure Diagnostics. About 5 GB of Event Counter data provides the source data for my Generating Big Data for Use with SQL Azure Federations and Apache Hadoop on Windows Azure Clusters post of 1/8/2012.
