Flickr could be most aptly described as agrarian pre-DevOps
2010
None
“Create a repeatable, reliable process for releasing software”
“If it hurts, do it more frequently, and bring the
pain forward.”
“If releasing software is painful, aim to release it every
time somebody checks in a change that passes all the automated tests.”
“a deployment pipeline is an automated manifestation of your process
for getting software from version control into the hands of your users”
2018
None
“The findings from our research show clearly that the value
of adopting DevOps is even larger than we had initially thought”
“the gap between high and low performers continues to grow”
Software delivery performance: 1. Lead Time 2. Deployment Frequency 3.
Mean Time to Restore (MTTR) 4. Change Fail Percentage
2019
None
“Most companies don’t include their databases in their DevOps practices”
“A key part of DevOps for the database is to
recognize that this schema is code”
“[the database schema] should be stored in source control, and
subject to the same processes and controls as application source code”
“you need to be able to upgrade the database schema
without breaking the application”
“you also need to be able to upgrade the application
and run it against an old schema version”
Postgres could be most aptly described as agrarian NoSQL
None
“speed and stability are both possible”
Software delivery and operational performance: 1. Lead Time 2. Deployment
Frequency 3. Mean Time to Restore (MTTR) 4. Change Fail Percentage 5. Availability
Elite performers: 208 times more frequent code deployments 2604 times
faster time to recover from incidents
DevOps could be most aptly described as decentralized cat herding
