    LoadComplete

    LoadComplete

    SmartBear

    LoadComplete is a load testing tool for creating and running automated load tests for web servers and services. It will help you check your web server’s performance under a massive load, determine its robustness and estimate its scalability. Load testing consists in simulating a massive load (requests) on a web server. LoadComplete automates creating load tests by recording actions you perform over web pages and simulating these actions with dozens and hundreds of virtual users working simultaneously. Each virtual user simulates a recorded scenario, and the entire load test simulates a real-life massive load on the server. LoadComplete produces detailed test results for generated traffic. You can also monitor various server metrics (like CPU usage) during the test run.

    CloudStorm

    CloudStorm

    Keysight Technologies

    Massive concerns around security are driving an increased use of encryption. An all-encrypted world is not far away. At the same time, the scale of traffic continues to grow at an exponential rate and the industry is moving to new cloud-based architectures. Users of services and applications, however, continue to expect their experience to be at or above the current level. To keep pace, network equipment manufacturers race to build higher-scale, more capable network security and application delivery solutions. In turn, the world’s largest cloud data center operators struggle to find the right balance between performance and security in today’s hyper-scale, dynamic world. The uncertainty that comes with this change is best mitigated through cloud-scale validation.
