What is Cavisson NetStorm?

Cavisson NetStorm is a cost-effective, performance-enhancing solution for enterprise applications. Users find it to be an extremely powerful load generator that provides an accurate estimation of Client Perceived Response Time (CPRT), allowing IT companies to guarantee Service Level Agreements (SLA). Its advanced technology can handle load variables, user realism, application realism, and network realism. NetStorm is a proven solution for finding the root cause of the issues where legacy solutions have failed. This has prompted many Fortune 100 companies to switch over to NetStorm.

• The solution enables massive load generation for accurate estimation of client-perceived response time.

• Users remark that NetStorm can generate high load with a single machine. Its Runlogic feature is very useful to send load to cover each and every flow of the application. The solution gives the ability to generate load with multiple load arrival models, helping components to be tested based on its usage.

• As the web matures, two opposite trends are coming together: web providers want to increase the bottom line while web users are becoming less forgiving. By using NetStorm, companies can save money by spending smarter.

• One reviewer writes, “It's a great load generating tool with integrated monitoring capability. The company has a highly talented client support to provide their services round the clock.”

• The solution is enterprise-ready, scalable, and stable technology.
  
  
• Another reviewer mentions, “Over the past decade, the product team has continued working on improving and enhancing their tools. It is now widely used both across and outside the country by many Fortune 500 companies. My hope is that they keep improving and stay competitive in the market.”
  
  
• The solution helps users focus on real-time transactions that occur at a very high rate.

• Another user comments that being a major retailer, they had to make sure that their applications were able to handle excessive load. Other load testing tools on the market were not able to replicate the complex and varying traffic patterns that they witnessed and that made it difficult to tune the application in order to remove slowness/issues and provide quality customer experience. This issue was handled with ease using NetStorm.
  
  
• NetStorm is priced well when compared to many well-known tools.

• One user mentions that NetStorm is an easy-to-use and powerful load generator that helps him get an idea of load times and be able to maximize client experiences.

• According to one user, “NetStorm setup is so easy. It can be installed on any Linux or Unix box or windows machine on-Prem or cloud. I'm not so into the pricing of the product but heard that it is competitive and less when compared to other load-generating tools. A single license of NetStorm can generate a high load to test multiple components at the same time.”

• One user notes that some of the benefits he saw are:

1. Users were able to reduce and/or increase load during runtime to successfully replicate production traffic during a production load test.
2. NetStorm’s script manager enabled users to create patterns matching their peak traffic days like Cyber Monday, Thanksgiving, etc.
3. NetStorm could easily analyze various conditions via the compare feature, which gives users the option to compare within a test run and with different test runs.

• Some of NetStorm’s key features include:
  
  
  • Internet-TrueTM WAN simulation
  • Internet-TrueTM load modeling
  • Goal-based scenario design
  • Web user behavior simulation: It comes with a built-in mechanism that allows modeling of page reloads and click-away by users.
  • Client-side testing
  • Built-in internet topographies
  • High performance (rendering time, on-load, DOM load, page load)
  • Caching metrics (network and browser cache)
  • Massive, internet scale load generation: This makes testing with millions of active users not only possible but easy to manage.
  • Offenders by DNS time, load time
  • Page score
  • Clips and recording of page-wise user interaction
  • Advanced tools
  • Powerful monitoring and diagnostics: With one click, analyze two or more members or measurements in the groups. The root cause can be determined by correlating spikes with other metrics.
  • Alerts: NetStorm allows you to set up an early warning mechanism in the form of behavioral or capacitive alerts to find out metrics deviating from its baseline.
  • Real browser simulation
  • Runtime comparisons with baseline: NetStorm offers the ability to validate new releases or fixes by performing comparisons with baseline.
  • Production scenario recreation
  • Reporting and dashboard
  • Trend analysis
  • Comparison of releases
  • Runtime percentile distribution
    
    
• According to one user, apart from the standard offerings given by other performance testing tools, NetStorm has the following additional capabilities:
  
  
  • Advanced reporting and analysis capabilities that enable users to deep dive into issues reported during load tests and identify faulty components.
  • Ability to add complex runlogic and runtime changes to simulate production-like behavior because it’s integral for users to create workloads that are similar to the ones witnessed in the production environment.
  • Easily integrates with APM products. This helps users in getting a 360-degree view of how their critical applications behave during peak load.
    
    
• Another reviewer mentions, “[NetStorm] designs dynamic scripts and scenarios, as per our requirements, which is one the most important features available in NetStorm. It helps us to do performance testing of our application in a periodic way.”

NetStorm does have a few drawbacks, however:

• Some users mention that although pricing is fairly reasonable, they would like to pay less.
  
  
• Other users note that the interface can be hard to learn at first.
