Defending the Network: Flow vs. Wire Data

In recent months, at multiple customers, I’ve had the opportunity to observe shockingly similar problems that follow an unfortunately common scenario: There is a perceived site issue A war room or incident is started The network is quickly thrown under the bus Why?

Why WAN optimization requires performance management

WAN optimization can only be as efficient as you let it be. Recently I’ve seen a good example that illustrates how, without diligent application performance management, multi-million WAN optimization investments can quickly turn into a lukewarm “implementation completed” outcome, to say the least. The challenge at one of our customers started in a typical way: a large company, with operations around the globe, facilitated by a large SAP ERP and… read more

Network App Performance: Application Deceleration Controller & DC RUM

Not too long ago I had an opportunity to work with a customer who was experiencing performance problems with their web-based HR application. Users at the headquarters location – about 30 milliseconds away from the data center – would occasionally experience page load times of 10 or 15 seconds – instead of the normal 2 or 3 seconds.

Network Virtualization and the Software Defined Data Center

I was recently having a discussion with one of my clients about the concept of network virtualization. During the conversation, in attempting to explain the business case, I referred to data center virtualization. This was met with some confusion, with the customer explaining that when he heard that term, his immediate thought was of server and desktop virtualization; that had already been done, hadn’t it? So this is a fair… read more

Ensure Availability & Performance in SAP's Digital Economy

SAP applications play a key role in fulfilling business processes in today’s digital enterprises. Availability problems, even those that impact single users, result in efficiency loss and in a worst case scenario may even stop the process.

A Fond Farewell To OpTier

The Darwinian laws of software evolution have struck once again. As was reported last week by Gartner, OpTier is calling it quits.
