● Problem solving mentality

● Self-motivation

● Great social skills

Dev/Ops

● Infrastructure as code means CODING

● Some tools are really good and perhaps you don’t need CODE

● Don’t been married to softwares or languages, next softwares/languages will be “better” than the current ones

● Don’t be a hero, work with your team and think of how to improve everything

● Patients, Resilience and good Communication skills are really important to practice DevOps mindsets.

Courses/Training

● Trainings are limited and brief (short duration)

● They never approach all tools, methods but they a good start point

● Perhaps a better way are to develop non technical skills

Devs/Ops/Managers

● Agile methodologies shouldn’t be “Follow strictly the process”, be flexible.

● Onboarding practice among teams

● Tools are relevant but people are more important to implement DevOps (Agile) process

● Don’t use root user as service owner

● Don’t allow frequently access directly in production databases

● Update as last as possible software versions (mainly securities updates)
