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.

- Aryaka Networks Launches a Cloud Solution for Application Delivery to Remote Sites -

Today, Aryaka Networks came out of stealth mode and announced its cloud solution for WAN optimization. The solution is based on a number of globally distributed points of presence for WAN optimization that sit on large carrier networks around the world. Aryaka allows organizations to deploy WAN optimization capabilities by using a SaaS platform and set up WAN optimization techniques in only a few clicks, without having to deploy any additional hardware.

The biggest area of change in the WAN optimization market over the last three years has been the delivery method of these solutions. The majority of announcements that have been made by WAN optimization vendors were centered around turning their hardware solutions into virtual appliances or enabling their products to better support managed WAN optimization services. This trend has been driven by the end-users’ request to simplify the management of WAN optimization solutions, reduce the total cost of ownership, support different network topologies and make these products more appealing for organizations that are deploying virtualization and cloud computing services. Aryaka’s solution takes this a step further and provides an innovative approach for addressing some of the key concerns that end-user organizations have about deploying WAN optimization solutions.

The trend of moving WAN optimization hardware out of the branch has been resonating with end-user organizations and a majority of WAN optimization vendors have been doing a good job of trying to adjust to it. However, Aryaka is not only taking WAN optimization solutions completely out of the branch, but also moving them outside of corporate firewalls, providing an almost CDN-like infrastructure for delivering these capabilities (which should not come as a surprise if you know that the founder of Aryaka was also a founder of Speedera Networks, a CDN company that was acquired by Akamai in 2005).

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.
