Uptime Report for my Live OakLeaf Systems Azure Table Services Sample Project: May 2012 = 100%

My live OakLeaf Systems Azure Table Services Sample Project demo runs two small Windows Azure Web role instances from Microsoft’s South Central US (San Antonio, TX) data center. This report now contains a full year of uptime data.

Here’s the usual Pingdom Monthly Report for April, which indicates service is back to normal after outage issues in April 2012.

Here’s the detailed uptime report from Pingdom.com for May 2012:

This represents a considerable improvement in uptime over April 2012. My Flurry of Outages on 4/19/2012 for my Windows Azure Tables Demo in the South Central US Data Center post updated 4/30/2012 provides details about the outage on 4/19/2012 and its root cause analysis.

Following is detailed Pingdom response time data for the month of May 2012:

This is the twelfth uptime report for the two-Web role version of the sample project since it was upgraded to two instances. 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 of the Windows Azure test harness instance.

I 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.

The 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.
