IT Imperative: Performance Testing Tools Inside the GigaOm Key Criteria ReportAny IT leader worth their salt wants to ensure that applications meet their required service levels and that they deliver a positive user experience. Performance testing is the insurance in that scenario. With it, an organization can test how responsive a system is under varying loads and scenarios to provide actionable feedback about the behavior of the system. Performance testing is now a critical part of site reliability engineering (SRE) and the quality-first approach seen as crucial in cloud-native environments. For businesses that create many custom-based applications, or that make extensive modifications to third-party systems like PegaSystems, Salesforce, and SAP, performance testing is critical. The risk of bugs or unplanned outages caused by application loads is simply unacceptable in these environments.
