Wire Data: A 20-year history & a bright future

While the term “wire data” may be relatively new, the concept isn’t; probes and capture agents have been collecting and examining network traffic almost from the beginning of network time. The term has been used casually by many network analysts, is particularly popular with Wireshark users, and – in a very casual Google search – was referenced in vendor documentation as early as March 2012. In fact, wire data has… read more

Does your Liquid Infrastructure float? Or are you sinking in what you don’t know?

With so many new web technologies available, one might assume that things are getting easier for the average Operations-minded DevOps professional, but they aren’t. In fact, things are becoming more difficult. It used to be that a little background in shell scripting and some basic knowledge of infrastructure—whether it be networking or servers—could get you a long way. Then came virtualization and the Cloud and software-defined everything. Today you find… read more

Network Virtualization and the Software Defined Data Center: Part 2

In last week’s post about Network Virtualization and the Software Defined Data Center, I pointed out that whatever approach you choose to take towards your modern data center network – SDN, NFV, a blend – an element of network virtualization will become fundamental to its architecture. I concluded by pointing out that the requirement to retain visibility will be paramount to its service-oriented success. But before I move to… read more

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

The Rise of the Liquid Data Center – How the Cloud, Docker and Micro Services change the game

Our industry’s perception of what a data center is and how it is provisioned has significantly changed with the adoption of cloud and virtualization technologies. What started as pure infrastructure on-demand has evolved to a powerful technology stack which we refer to as the Liquid Datacenter. The Liquid Data Center So, what is the Liquid Data Center all about? In short the Liquid Data Center is the fully virtualized software-defined… read more

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. It’s no secret that OpTier and Compuware have competed fiercely over the years. But the disappearance of a well-known player in the Application Performance Management (APM) market is nothing to rejoice about. OpTier was once among the vendors at the forefront of the business transaction… read more

The Mystery of the Little Big Transaction Time

There is a common belief is that to make the right decision or to find the root cause of a problem we need to analyze as much information as possible. We, citizens of the information society, however, sometimes feel overloaded and strained with information. As a result, we try to weed out unnecessary bits quickly and focus on only those that can bring us closer to solving the current problem. Analyzing a performance problem usually requires an end-to-end view of the complete transaction that impacted the end user experience. In this article we will show how numbers can be misleading and, if not carefully analyzed, may seem pretty insignificant. We also discuss how a proper data analysis tool with fault domain isolation workflow and an understanding of what is normal (baselining) can help us to get to the bottom of the issue, e.g., that a database server is experiencing a performance problem. read more

Filling Citrix Visibility Gap with Application-Aware Network Performance Monitoring: Part 2 – End-User Experience Monitoring

Citrix XenApp or XenDesktop are a perfect fit for lowering the costs of desktop management and simplifying access to the hosted applications from any device. Last week we discussed some challenges to application performance monitoring (APM) introduced by Citrix. Apart from getting yet another component in the data center to take care of, the virtualized application delivery becomes “black boxed” from the APM perspective. It gets harder to isolate the fault domain to the network, the infrastructure, or the applications themselves. Today, we will look into monitoring end-user experience of applications delivered through Citrix. read more
