Why Preview Environments Are The New Thing in DevOps
Consider the scenario where a complex product is being developed by dozens of engineers working on different features of a product. Not only the development environment is the same, but the staging environment is also shared. As different features are merged into the shared environment, they break the code. So QA has to wait until this is fixed. A feature or bug fix may be working perfectly on the developer’s own machine, but there is no way for the QA team to test that one feature in isolation.
