The best explanation for me(so far) about DevOps
Ops – it operates the application in production
That is, it assure service uptime and availability(responsiveness)
### Deploy to produciton
### Monitoring (for service uptime/availability)
– if the service is down, it will restart it
– if the machine/server is going crazy(if there is high load, no disk space, etc..), it will alert, intervene, solve, investigate
– if the application throws a lot (of unexpected) errors/exceptions
### Service responsiveness
– scaling, add a new node
Later Update
