Where the Cloud Touches Down: Simplifying Data Center Infrastructure Management

Thursday, July 25, 2013
10:00 AM PT/1:00 PM ET

In most data centers, DCIM rests on a shaky foundation of manual record keeping and scattered documentation. OpManager replaces data center documentation with a single repository for data, QRCodes for asset tracking, accurate 3D mapping of asset locations, and a configuration management database (CMDB). In this webcast, sponsored by ManageEngine, you will see how a real-world datacenter mapping stored in racktables gets imported into OpManager, which then provides a 3D visualization of where assets actually are. You'll also see how the QR Code generator helps you make the link between real assets and the monitoring world, and how the layered CMDB provides a single point of view for all your configuration data.

Amazon's EC2 Outage: A Closer Look


Amazon Web Services once again cites human error spread by automated systems for loss of load balancing at key facility Christmas Eve.

On Christmas Eve, Amazon Web services experienced an outage at its Northern Virginia data center. In a prompt follow up, it issued an explanation on Dec. 29, apologized to customers and said it wouldn't happen again. It was the fourth outage of the year in its most heavily trafficked data center complex.

Explanations in the press of what happened, based on the Dec. 29 statement, were relatively brief. The Wall Street Journal, for example, stated that Amazon spokesmen blamed the outage "on a developer who accidentally deleted some key data ... Amazon said the disruption affected its Elastic Load Balancing Service, which distributes incoming data from applications to be handled by different computing hardware."

To an IT manager thinking of using Amazon, that leaves as much unexplained as explained. A developer disrupted running production systems? Development and production are kept distinctly separate in enterprise data centers for exactly the reason demonstrated in the Dec. 24 outage. The developer, Amazon took pains to explain, was "one of a very small number of developers who have access to this production environment." Amazon is a large organization with many developers; how many developers had access? Read full story on InformationWeek
