Synthetic testing simulates real-user behaviors within an application or service to pinpoint potential problems. Here’s a look at why this testing matters, how it works, and what companies need to get the most from this approach. What is synthetic testing? RUM, meanwhile, requires actual users.

How viewers are able to watch their favorite show on Netflix while the infrastructure self-recovers from a system failure By Manuel Correa , Arthur Gonigberg , and Daniel West Getting stuck in traffic is one of the most frustrating experiences for drivers around the world. Logs and background requests are examples of this type of traffic.

Automating quality gates is ideal, as it minimizes manually checking and validating key metrics throughout the SDLC. By actively monitoring metrics such as error rate, success rate, and CPU load, quality gates instill confidence in teams during software releases. Several tools can be used to collect metrics in load/performance testing.

This becomes even more challenging when the application receives heavy traffic, because a single microservice might become overwhelmed if it receives too many requests too quickly. The Envoy proxies also collect and report telemetry on all traffic among the services in the mesh. Why do you need a service mesh?
