When high volumes of web transactions are simulated in short periods of time to ensure your site has the capacity and ability to perform well in order to exceed expectations, it's probably done in the traditional way.
Large companies usually choose a more traditional load testing which is internal testing meaning - tests are run from behind your company’s firewall.
Internal testing only allows you to see potential issues from within your own controlled environment, and does not test the countless issues that might evolved from hundreds of various reasons, such as a user might be accessing your site, hitting the application using a low connection line and causing network issues while waiting for a response from you database and by that holding the other users and causing a high response time in the whole system. It also does not take into account different locations, various connection speeds or real-user experience.
Global load testing is the best solution for large companies which operate on a global level by multi-continents branches and offices. It provides an independent, third-party view of your site and uncovers information that isn’t always available from an internal test
Global load testing is best achieved by cloud testing, which executes from different locations on the globe, and best simulate a real-life scenario and truly capable of finding issues and optimizing the system, it also has those advantages as well:
- Significant reduction in capital expenditure, including costs on hardware,
software and utility costs such as reduce the number of needed working stations. - Decreased management overhead due to easy and immediate access to
a pool of hardware, applications, and higher data availability anytime anywhere. - Provides end-users with a user-friendly interface for managing test campaigns and test execution. It allows a user's real-life experience, display and browses their test execution results.
Load/performance cloud testing gives the company a true insight on the system overhaul and pinpointing issues that wouldn't be discovered through internal load test. It's the best cost-effective solution when you need to simulate thousands of users working simultaneously from different locations on the globe.
