Long-running processes such as email should delivery being run in background jobs?
Are there redundant \(at least two\) web and background processes running?
Are we using SSL? Never send credentials unencrypted over public network. Always use encryption \(such as HTTPS, SSL, etc.\).
Are API requests being made via a separate subdomain \(api.example.com\)? Even if the same app, this gives us architectural flexibility in the future.
Are we monitoring performance and uptime?
Are deploys done manually at a scheduled time when teammates are fresh and available if something goes wrong?
Do deploys follow a well\-documented script?
A method exists for replicating the state of one environment in another \(e.g. copy prod to QA to reproduce an error\)
All repeating release processes have been automated
No secrets are stored in version control
Is config stored in environment variables?
Are new variables deployed?
Server environments are up\-to\-date
A plan for updating the server environments exists
Are we backing up our production database?
Backups are running and verified
Restoring from a backup has been tested
Rolling back a deployment is possible
Logging is turned on
There is a well defined process for accessing and searching through logs
Logging includes exceptions and stack traces where appropriate
Are we sending logs to a remote logging service?
Are we tracking errors?
Errors can be mapped to stack traces
