Second wall of confusion

• Fear of Change - application being brittle and vulnerable might break or go down

• Risky Deployments - pray and push the code quietly to PROD and get a sense of relief

• Developer Mindset – “It works fine on my system”

• Isolation and Splitting of Teams - divides the Team into “us and them”

• Battle between SysAdmin and developers

DevOps is About CAMS

• to business

• Time-to-value is much shorter because IT cycle time is greatly reduced

• Software features are released more quickly and regularly

• Releases are stable and predictable

• Faster implementation and better quality

• Reduce and eliminate wasteful deliveries

• Collaboration between your development and IT operations teams

• to customers

• Easy and faster access to new features and business functionalities

• Accept changes in smaller, granular and manageable portions

• Less disruptive upgrades -> take less time -> low cost -> require fewer resources

• Better visibility of the features for the next release

• Better change management in the environment

Benefits

Second wall of confusion

•  ”The DevOps movement is characterized by people with a multidisciplinary skill

set - people who are comfortable with infrastructure and configuration, but also

happy to roll up their sleeves, write tests, debug, and ship features”

• “This, of course, has a positive effect on the bottom line - better reliability and

availability, happier clients, faster time to market, and more time to focus the

team's energy on core business rather than wasteful administration and

firefighting”

• Another important thing to note “DevOps is a not a Technology Problem,

it’s a Business Problem”
