Engineering teams adopting microservices architecture have typical CI/CD workflow.Shared staging environments create bottlenecks which slow down teams and undermine the advantages of microservices.Bugs from one team can block multiple others due to shared staging environments.Multiple PRs being merged daily makes it hard to isolate why a test fails.Multiple teams waiting for their turn to test features in staging delays releases and creates bottlenecks.Automated tests scheduled for off-peak hours delay feedback loop and productivity.Shared staging environments lead to slower shipping of features and patches.Isolated testing eliminates the problems caused by shared environments and enables true continuous delivery.Platforms like Signadot and other companies have adopted the model of isolated testing.Isolated testing allows teams to catch issues early in the development cycle, reducing the complexity and cost of fixing bugs later.
