Uptime Report for my Live OakLeaf Systems Azure Table Services Sample Project : April 2012
The Cloud Zone is brought to you in partnership with Mendix. Better understand the aPaaS landscape and how the right platform can accelerate your software delivery cadence and capacity with the Gartner 2015 Magic Quadrant for Enterprise Application Platform as a Service.
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. I didn’t receive (or misplaced) the usual Pingdom Monthly Report for April, so here’s the detailed uptime report from Pingdom.com for April 2012:
This is the first case of monthly uptime below the 99.95% minimum Windows Azure Compute Service Level Agreement (SLA) guarantee since upgrading the sample app to two instances. 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 March 2012:
This is the eleventh uptime report for the two-Web role version of the sample project. 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.
