Their new paradigm? "Release three times per day, with no more than three hours between when code is committed and when that code is available to members," according to a senior engineer on LinkedIn's blog. This requires a three-hour pipeline where everything is automated, from committing code to releasing it into production, along with automated analyses and testing. "Holding ourselves to this constraint ensures we won't revert to using manual validation to certify our releases."
