Different environments in software development where code is built, tested, and deployed. Development is for creating and testing code, testing is for quality assurance, and production is where the software runs for end-users.
Think of environments like different stages in a play: rehearsals (development), dress rehearsals (testing), and the live performance (production).
Developers work on new features in the development environment, test them in a testing environment, and then deploy the final version to the production environment.
Having separate environments ensures that code is properly tested before it reaches users, reducing the risk of bugs and downtime.
Proper environment management reduces the risk of releasing faulty software to customers, protecting the business from potential reputational and financial damage.
Keep environments isolated to prevent cross-contamination; use consistent configurations across environments; regularly refresh testing environments with data from production.
Differences between testing and production environments causing unexpected issues; inadequate testing before deploying to production; insufficient monitoring of production environments.
Environment uptime, bug detection rate, deployment success rate.
