Industry analysts tend to classify vendors into technology "buckets" and create "labels" for each of them, as that makes it easier to compare products, capture key trends and provide context around problems that these products are addressing. This method also resonates with some technology marketers, as it allows them to partially benefit from promotions that other vendors and media are conducting around a label of a technology bucket their product was put into.

The term "application performance management" (APM) has been one of the hottest technology "labels" over the last few years. Performance of enterprise applications impacts nearly all of the key business goals, and it shouldn't come as a surprise that technology solutions for managing performance of these applications has been very high on IT agendas. With that said, it should be even less of a surprise that technology vendors, who are involved in managing the delivery of applications to business users in any way, realized this opportunity and started calling themselves "APM vendors". However, every "hot" industry term has an expiration date attached to it and sometimes it doesn't take long for a company to go from being one of the biggest promoters of an industry term to getting to the point where it doesn't even want to be associated with it.

Back in 2008, there were more than 50 technology vendors that used the term APM to position products that they provide and that number is now down to less than 30. So, had these 20+ companies gone out of business or completely changed their product portfolios? No, but they had realized that the term APM got diluted and that it is in their best interest to separate themselves from technologies that address the same problem as they do, only from a different perspective.

Emergence of new categories

Being thrown into the same technology bucket with companies that are addressing a similar problem from a different perspective could be a major challenge for many technology companies. Organizations that are in this position typically have two options: 1) wait until the market matures to the point when it becomes obvious that their solution is significantly different than other products in the same "bucket", or 2) coin a new term to describe a category in which their product belongs, promote the heck out of it and hope that it will become an industry accepted term. It took a combination of these two approaches to somewhat change the boundaries of the APM "bucket". That resulted in more market awareness about the differences between two groups of products that are also addressing challenges of managing application performance, but doing it from different perspectives: end-user experience monitoring and business transaction management (BTM).

The increased interest of end-user organizations in having visibility into how their applications are performing, not only from the perspective of their IT departments but from the perspective of business users, resulted in more market awareness about the role that end-user experience monitoring solutions are playing in managing application performance. The market matured enough to become more aware of the fact that different flavors of technologies for monitoring the quality of end-user experience, such as those provided by Aternity, Knoa Software, Coradiant or AlertSite, do not compete against, but complement vendors such as OPNET, OpTier or Quest's Foglight.

On the other side, vendors that specialize in managing application performance from a business transaction perspective also found a way to raise awareness about the differences between their solutions and many other APM products. This resulted in an increased adoption of the term BTM when describing capabilities of these solutions. These solutions are taking a different approach when addressing issues with application performance, as compared to some other APM vendors, and enable organizations to monitor the performance of applications across an entire transaction flow. Some of the vendors that fall in this group include OpTier, Nastel, INETCO, Correlsense, Precise Software, dynaTrace and AmberPoint (acquired by Oracle).

Over the last two years, technology vendors have been moving away from using the term "network monitoring" and replacing it with "application performance management." The main reason is that the performance of corporate networks is increasingly measured by the performance of the applications delivered over those networks. As a result, businesses are replacing familiar network-specific metrics, such as network uptime and time to troubleshoot network performance issues, with metrics like application availability and quality of experience as key performance indicators on their networks.

These changes are forcing vendors to enhance their product portfolios and provide more capabilities for monitoring the performance of networked applications in terms of measuring how fast information is delivered to end users via the network, the application itself or the Web services infrastructure, and pointing to possible problems. New opportunities are also being created in the emerging applications performance management (APM) market, including providing it as a managed service, although only a few telecom service providers have focused in on the trend so far.

TRAC's survey research shows that the top goals for end-user organizations when deploying solutions for WAN optimization are to improve the speed of applications over the WAN and increase network throughput. However, the survey also shows that the top challenges for managing the delivery of applications to end-users are caused by lack of visibility and control over the network traffic. In order to deal with challenges of ensuring seamless delivery of business critical applications over the WAN, organizations need to ensure that they are deploying management solutions that include strong capabilities across three key areas: acceleration, visibility, and control.

This report from TRAC Research examines capabilities that organizations are putting in place to ensure that applications are delivered over the WAN at optimal levels of end-user experience.

When WAN optimization technologies were first introduced to the market, solution providers were looking to differentiate from each other mostly based on how fast they could move the data across the WAN and how much they could save for end-users in cost of bandwidth. However, as the complexity of network traffic increased, technology vendors had to provide more than just pure acceleration, data reduction, or basic bandwidth management capabilities. As a result, the ability to fully manage performance of applications delivered over the WAN is now becoming the key point of differentiation among vendors.

Network performance monitoring solutions are not one of those “cool” technologies that get a lot of coverage in the media and these products are sometimes perceived as using an old approach to solve new problems. It’s all about capturing and analyzing packet flow data, right? Well, not really. Not many people realize how much this market has changed over the last 3-4 years.

TRAC Research will cover trends and key vendors in this market in several upcoming reports, but here is a high level overview of 4 key trends that drove some major changes in this market.

It is About Applications on the Network, Not the Network Itself

Back in 2006, I conducted a number of interviews with folks that were in charge of network performance.  The top metric that they were using in that time to evaluate how their networks were doing was unplanned network downtime. I did a similar round of interviews in late 2007 and unplanned network down time wasn’t even one of the top three KPIs that they were using to evaluate network performance (even though it was still extremely important for them). Between these two rounds of interviews, metrics, such as application response times and application availability, became the top indicators of the health of enterprise networks. These changes in end-user needs had a major impact on network monitoring vendors. They caused several major acquisitions, a lot of significant product upgrades, new vendors entering this market, significant changes in messaging and positioning and opened several new markets for vendors that were able to adjust to these changes.

Over the last 2-3 years, the term “Application Performance Management” (APM) became an integral part of marketing messaging for more than 70 technology vendors. Even though solutions provided by all of these vendors are helping to improve the speed and availability of business-critical applications, these vendors are providing solutions that are significantly different. These solutions could range anywhere from network performance monitoring to application acceleration, Web management and even managed/carrier services.

However, the APM as a general concept has become relatively easy for decision makers of end-user organizations to digest, as it hits all key pain points that IT organizations are dealing with. As a result, multiple vendors were more than happy to jump on this bandwagon and position themselves as players in this space.

Other than the language in their press releases and marketing collateral, these vendors really have nothing else in common. Technology wise, how similar are the offerings of F5, NetQoS, Keynote Systems and OpTier? They are not similar at all.
