General definition of DevOps
A collaborations of (software) development and its operations in the scope of
departmental responsibility, communication, people and process

Modern definition
(from https://aka.ms/DevOps)
DevOps is the union of people, process, and products to enable continuous
delivery of value to our end users. The contraction of “Dev” and “Ops”
refers to replacing siloed Development and Operations to create
multidisciplinary teams that now work together with shared and efficient
practices and tools. Essential DevOps practices include agile planning,
continuous integration, continuous delivery, and monitoring of
applications.

The changes to method XYZ are incompatible with mine, how do we merge now…
When did we decide to upgrade to version…
I thought you fixed that two month ago…

Common problems
• Developers often perceive things works well on their environment
• No strong team integration in the code (how far you are sure developer as
team player won’t break the code on every code commits?)
• No clear line or borderline for communications between dev and ops
• Tedious manual deployments, often not idempotent (is there a complete
rollback on any failed steps?)
• Operations puts constraints near end of development phase
• No easy way to reproduce with desired configuration requirements

…which brings us these general facts
Dev
• TDD are often not enforced
• Often dev imagining things with higher
ideals environment with no budget
constraints
• Dev can’t go beyond pure dev
• Dev is isolated to any basic infrastructure
knowledge
Ops
• Ops don’t want to look further on
monitoring, only care the app won’t
break others
• Ops don’t want to be bothered by the
consequences of platform changes
• Ops often constrained with business
realizations dilemma such as budgets
• Ops don’t want to know development
needs alignments

Unseen problems
• Licensing in terms of SAM, Software Asset Managements (number
of seats, core, devices, users)
• Legal compliance of OSS License model (sample cases: Facebook
ReactJS, GPL vs LGPL, MS SharedSource of .NET Framework)

DevOps maturity efforts
• Communications between Dev and Ops (it doesn’t have to be special DevOps
guy/staff)
• Automation: CI in Dev, CD in both Dev and Ops
• Requirement managements: projected number of users defined first, with basic
knowledge of actual hardware/software requirements to drive initial SAM
requirements
• TDD mentality enforced to Dev and Ops (even deployment needs to be tested
before)
• Governance: any third party software/libraries used especially OSS software must be
listed with the license models at initial/starting development phase
• Governance: change management regular meeting
