Design DB VS Valist

Valist is an infrastructure automation service that creates staging environments for every new update for a web application so that it can be tested in isolation. It aims to make agile product and development teams more efficient by integrating with tools they use such as Jira, Pivotal Tracker, GitHub, and Slack. When a new pull request is made, a staging environment is created automatically given a configuration file to host the application and other services like backends and databases. A link to the website is then shared in GitHub and other connected tools so that product owners, QA testers and other developers can test the changes to verify that it works correctly and validate that it solves the need.
