Shunra vCat™ Gain Confidence in Application Performance... Before You Deploy!

Over 60% of the performance problems that plague production applications today could be avoided with a more proactive approach to performance testing and validation early in the application life cycle. With analysts estimating the total cost of performance issues occurring in production at $45,000 or more per hour, the ability to identify and remediate potential performance bottlenecks before deployment is critical.

vCat is a proven solution that allows organizations to incorporate real-world network conditions, such as variable bandwidth, latency, and packet loss, directly into their test environment. By incorporating real-world network constraints, organizations gain valuable

insight into expected real-world application behavior for establishing and validating performance levels prior to rollout, as well as for troubleshooting issues occurring in production.

Emulating the real world is essential to gaining confidence in application performance before deployment and uncovering design and implementation problems – such as chattiness, latency-sensitive transactions, caching inefficiencies and other network performance issues – early in the development life cycle, when it is most cost-effective to do so.

Shunra vCat™ is a Windows-based network emulation software solution that enables organizations to test application performance under a variety of current and potential network conditions, directly from a desktop. vCat transforms traditional LAN-based testing environments, enabling real-world network constraints to be emulated within the testing environment in order to generate performance test results that are reliably predictive of real-world application behavior.

What VMware does for the data center, Shunra vCat does

for the production network. TEScott Moore

vCat provides an accurate, real-world network model with the ability to emulate

bandwidth, packet loss and latency, which is essential

for us to meet our rigorous Quality of Service goals.

Accommodating a dynamic network with streaming services is complex, and

Shunra helped us fine tune the logic and the behavior of the algorithm for conditions that

we could not otherwise test.TESrinivas Manapragada

Collaboration – Test scenarios are easily shared by users and managed from a central location. Each vCat client simulates a network link so that members of a performance testing team can test applications under varying network conditions, directly from their own desktop.

Integration with Shunra NetworkCatcher – Users can leverage NetworkCatcher to capture real-world network conditions and download interval statistics for bandwidth, latency and packet loss directly into the vCat test environment.

Intuitive GUI and test setup – Users can select network scenarios from a library of typical network topologies, allowing for fast test set up without networking knowledge. Or, custom topologies can be created through vCat’s modeling interface. Either way, users are on the fast path to gaining confidence in application performance.

Mobile hot spot – vCat enables mobile application performance testing from a WiFi-connected smartphone or tablet, as well as a local area network connection.

HTTP and Web Analysis – Web and Mobile analysis capabilities provide key insight into transaction response times, enabling fast analysis and the ability to quickly identify areas for optimization.

Optimization recommendations – Leveraging a set of proprietary and proven rulesets, vCat automatically delivers a performance scorecard, along with customized and specific recommendations for optimizing the performance of Mobile and Web applications. These recommendations have been tested and shown to improve performance by over 40%.

Flexible emulation – vCat emulates bandwidths up to 100 Mbps and accounts for both available (allocated) bandwidth and variability in available bandwidth, enabling more reliable emulation of Mobile and Web network conditions. In addition, mobile-specific application performance testing is made easy via a library of pre-defined mobile emulation parameters based on typical and worst case mobile network conditions.

Key Features: vCat delivers capabilities designed to improve an organization’s ability to create a reliable performance test environment, analyze performance test results, and take immediate and effective action to both remediate problems and optimize application performance. Key features of vCat include:

vCat™

Enclosed TestingEnvironment

vCat delivers unsurpassed performance insight, early in the application life cycle. With vCat, organizations can proactively predict real-life application performance over any network – WAN, Web, Mobile and Cloud – improving the ability to find and fix performance problems, determine capacity requirements, ensure adherence to service level objectives, and much more. Shunra vCat is an ideal solution for development, testing and networking teams, as well as anyone who needs to quickly and accurately understand whether their code or application is ready for the network and remote end-users. vCat delivers confidence in application performance.

Why vCat™ ?

vCat is a PC-based performance testing solution which effects the available

bandwidth, latency and packet loss on a network interface (NIC) in order to emulate real-world network conditions for applications running on the same PC. This enables more accurate performance testing, analysis and optimization.
