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.

A Network Computing Webinar:
SDN First Steps

Thursday, August 8, 2013
11:00 AM PT / 2:00 PM ET

This webinar will help attendees understand the overall concept of SDN and its benefits, describe the different conceptual approaches to SDN, and examine the various technologies, both proprietary and open source, that are emerging. It will also help users decide whether SDN makes sense in their environment, and outline the first steps IT can take for testing SDN technologies.

There's No 'I' in Team--Or App and Network Performance Management

Football season is in full swing, and, like many fans, I'm eagerly consuming news items, reports and replays of the top games of the week. And when you watch a lot of football programming, you regularly see coaches and experts talking about the elements and practices that separate the top teams from the bottom dwellers.

A common refrain that coaches and experts repeat is the importance of all three phases of the game and how all the units of the team need to work together to succeed. Watching games, it's easy to see that in action: Teams with good offenses but lousy special teams and defense can put up a lot of points but often don't make it to the postseason or don't last long if they do.

But this is a lesson that, for a while, hasn't taken hold in the application and network performance infrastructures of many businesses. In fact, it has been all too common for a company to have an application team that worries just about testing and has little concern for network issues. Or network admins who are looking at only network capacity and not at how performance affects the user experience.

Clearly, these organizations need a good head coach who can whip them into shape and ensure that all groups are working together to achieve the highest levels of application performance. That's because many of these same team-oriented principles apply just as much, if not more, in application performance management as they do in football.

When an application suffers from a performance or usability issue, the cause could be in the code, or due to a server or network issue, an interface design flaw, or some combination of the above. The code flaw could be found by testing tools used by the development team, but they would be ignorant of the server issues that would be readily apparent to the data center team.

The first step to overcoming this problem is to get the different teams to stop their siloed approaches and start working together. But this solves only part of the problem.

The other issue is that the different teams don't really understand or know how to get the most value out of the performance management and monitoring tools in use by each group. Testing and debugging tools can be as hard for network admins and business managers to understand as a quarterback's playbook would be to a defensive tackle.

And while business managers might understand that red lights are bad in a network monitoring console, they won't really know how to figure out what the underlying issue causing the red lights is. That's why the next step is to improve translation layers and integration among the different performance management tools in use by each group. By enhancing the flow of information, this can make it possible for the different teams to work together to understand application performance and detect and remove potential issues.

And these steps can pay off in improved application performance and increased monitoring and management capabilities. In my recent report, Overcoming Application Performance Walls, survey data showed that businesses that have a unified approach to performance management are 75% more likely to have implemented capabilities such as identifying sources of delay in application performance. And this approach should become more common in businesses, as 88% of organizations centralize management of application performance, or plan to in the next 12 months.

In football, when the offense fumbles the ball, it isn't just their problem. The defense has to go out and limit the damage of the turnover, and special teams needs to ensure good field position to get the offense back on track.

Similarly, when an application fails, it isn't just the application development team's problem. When all of the groups within an IT infrastructure are able to work together to manage performance, everyone wins.
