On October 22, Riverbed acquired CACE Technologies, a network monitoring vendor. CACE provides solutions for network traffic capture and analysis and it is also a sponsor of Wireshark project, an open-source network monitoring tool that is being deployed by millions of end-users. CACE's products will become a part of Riverbed's Cascade business unit and Riverbed stated that Wireshark will remain a free tool.

This acquisition can impact Riverbed's market position in three key areas.

1) WAN Optimization

Riverbed has been experiencing a lot of success in the WAN optimization market and many of their competitors find it difficult to compete with data reduction and the acceleration capabilities of Riverbed's Steelhead technology. Even though WAN acceleration techniques alone are enabling organizations to improve application performance over the WAN, due to complexity of WAN traffic, organizations are increasingly looking for WAN optimization solutions that couple acceleration techniques with capabilities for visibility into WAN performance.

Riverbed responded to this trend by acquiring a network visibility vendor, Mazu Networks, in January of 2009. Even though the Mazu acquisition allowed Riverbed to add advanced network monitoring capabilities to its portfolio, it didn't significantly impact Riverbed's position in the WAN optimization market, as Mazu products were provided as a separate product offering from Riverbed's WAN optimization gear through the Cascade business unit. Riverbed did take several steps to tighten integration with Cascade solutions, but it hasn't provided both acceleration and visibility capabilities on a single platform, which is the approach that vendors, such as Exinda, Expand Networks, Ipanema Technologies and Silver Peak, have being using to create competitive advantages.

The acquisition allows Riverbed to enhance visibility capabilities of their WAN optimization solution by integrating CACE Pilot with their Steelhead appliances. CACE Pilot is a solution for analyzing network performance and using it to process data that is being collected by Steelhead appliances will enable Riverbed to provide WAN acceleration and visibility capabilities through the same platform.

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.

As server virtualization is becoming one of the fastest growing IT initiatives in the enterprise, organizations are looking to extend the benefits from these projects to new areas. As a result, they are looking to virtualize not only their servers and storage, but also to achieve similar benefits from virtualizing their desktops. For end-users, this means that their operation systems and software that used to be installed on their desktops are now being hosted in the datacenter and accessed across the network.

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.

One of the most significant changes in this market, however, is the emergence of new delivery methods for providing these WAN optimization capabilities to end-users. WAN optimization.

New applications, IT initiatives and end-user requests for improving the effectiveness of managing enterprise infrastructure are changing the role that WAN optimization solutions play in the enterprise. Benefits that end-user organizations are looking to achieve from deploying various WAN optimization and accelerating technologies go beyond just mitigating bandwidth upgrades and improving network throughput. WAN optimization solutions are becoming one of the key enablers of top IT initiatives. IT projects such as data center consolidation and desktop and server virtualization improve the flexibility of managing computing resources; but, at the same time, they are moving computing resources further away from the end user, which increases the amount and complexity of data that is being transferred over the WAN.

When talking to end-users I often get questions like: who are the WAN Optimization vendors that should be on our “short list”? And it is nearly impossible to answer this question without asking them 10 or so questions, such as: how many network locations does your company have, how many users per location, what applications are your company running, what IT projects are you looking to support, what are your security and compliance requirements, etc.

If we are talking about an end-user company that has thousands of locations, an average of 30+ users per location and is looking to conduct a data center consolidation, companies like Ipanema Technologies and Silver Peak are very likely to be on their list. If we are talking about a company that has less than 500 employees, has a relatively small IT department and is running bandwidth-intensive, time-sensitive applications and technologies such as video conferencing or VoIP, then vendors like Exinda should be higher on their list then some of the others. This is not to say that the vendors mentioned above are the best solutions for the usage scenarios that I described, it is only to say that these solutions are more effective (from both business and technology perspectives) in certain use cases.

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.
