I realize in general that&amp;#x27;s an impossible task, but specifically I&amp;#x27;m thinking of something like a database. Is there a way for each &amp;quot;server&amp;quot; to get a private copy of the database? Otherwise it seems like if I create a non-backwards-compatible migration (let&amp;#x27;s say I drop a table that&amp;#x27;s no longer necessary) I could break servers that were spawned for other commits.</text><parent_chain><item><author>colinchartier</author><text>Hey HN,&lt;p&gt;We&amp;#x27;re Lyn &amp;amp; Colin and we built Layer - It creates a unique staging server for every commit.&lt;p&gt;Before Layer, I was CTO of a startup with a 10-person developer team, and dealing with staging servers (and end-to-end tests) was one of the most annoying parts of our workflow.&lt;p&gt;Layer lets you define staging servers the same way you define Docker containers, and get a unique one for every commit going back a week.
