DevOps introduction

DevOps
DevOps is a software engineering culture and practice
that aims at unifying software development (Dev) and
software operation (Ops).
DevOps 01 Introduction
DevOps Process

DevOps
DevOps aims at shorter development
cycles, increased deployment
frequency, and more dependable
releases, in close alignment with
business objectives.
DevOps Process
M.M. Heegstra

DevOps
The main characteristic of the DevOps movement is to
strongly advocate automation and monitoring all the
steps of software construction.
From integration, testing, releasing to deployment and
infrastructure management.

The use of DevOps
DevOps is not only for supporting IT, it can also be used to support the business strategy and
to improve business processes.
The intention of DevOps can be to establish the software and IT services supply chain to
support the business and to manage the whole process to maturity.
DevOps Process
M.M. Heegstra

The use of DevOps
The DevOps framework should support business
outcomes directly, not only collaboration with
development and operation for IT services.
The use of DevOps should be evaluated by business
outcome, not by an IT project scope and IT outcome.
DevOps Process
M.M. Heegstra

DevOps Process
The use of DevOps
DevOps is not a single tools, methodology, skill set or
organization structure.
DevOps is a framework combining all of these for
organizations to establish stream-lined processes to
enable the business to operate faster and react to
changes more quickly.
DevOps can also enable maturity by using the Plan-Do-
Check-Act cycle.

DevOps Culture
DevOps initiatives can create cultural change in
companies by transforming the way Operation,
Developers and Testers collaborate during the
development and delivery processes.
Getting these groups to work cohesively is a critical
challenge in DevOps adoption.
DevOps Process
M.M. Heegstra

DevOps Culture
DevOps principles demand strong interdepartmental
communication.
Team building and other employee engagement
activities are often used to create an environment that
fosters this communication and cultural change.

Goals
The goals of DevOps span the entire delivery pipeline.
They include:
1. Improved deployment frequency
2. Faster time to market
3. Lower failure rate of new releases
4. Shortened lead time between fixes
5. Faster mean time to recovery
DevOps Process
M.M. Heegstra

Goals
Simple processes become increasingly programmable
and dynamic, using a DevOps approach.
DevOps aims to maximize the predictability, efficiency,
security, and maintainability of operational processes.
Very often, automation supports this objective.
DevOps Process
M.M. Heegstra

DevOps Process
Goals
DevOps integration targets product delivery, continuous
testing, quality testing, feature development, and
maintenance releases in order to improve reliability
and security and provide faster development and
deployment cycles.
Many of the ideas (and people) involved in DevOps
came from the enterprise systems management and
agile software development movements.

The enterprise system
The enterprise holds both the System of Engagement
(SoE) and the System of Record (SoR).
The SoE is focused on speed and the SoR is focused on
business continuity.
The problem is how the SoR can adapt quickly to
changes to the SoE to maintain business continuity.
DevOps Process
M.M. Heegstra

The SoR in most enterprises is struggling with the use
of legacy applications/systems and can be helped
through the use of DevOps building stream-lined
processes with just-in-time (JIT) concepts.

The pillars and foundation | Disciplined Agile
A disciplined Agile development team is a key to the success of a DevOps implementation.
Disciplined Agile means:
1. Stabilized Velocity
2. Adaptability for change
3. Always release high quality bug free code
DevOps Process
M.M. Heegstra

A more frequent and faster release cycle of IT services
to react to business changes depends on the speed of
development.
The quality of work is the most important item and this
can be supported by splitting work into small tasks.
DevOps Process
M.M. Heegstra

The concept of JKK (Ji-Koutei-Kanketsu) helps keep a
high quality of work.
JKK means 100% completion of an item.
DevOps Process
M.M. Heegstra

The Definition of Done or completion must be defined
clearly for everybody.
The product owner may change the mission from not
only managing product backlogs but also by planning
the operating cost of IT service.

The pillars and foundation | Continuous Delivery
Continuous delivery is the automated implementation
of the application build, deploy, test and release
processes.
A key focus is on testing such as acceptance testing and
performance testing.
DevOps Process
M.M. Heegstra

Every organization will have differences in the
implementation of their deployment pipeline
depending on their value stream for releasing software.
A key success factor is to establish only a single
deployment pipeline for IT services.

The pillars and foundation | IT service management
As technology is a core component of most business
processes, continuous or high availability of IT services
is critical to the survival of the business as a whole.
This is achieved by introducing risk reduction measures
and recovery options.
DevOps Process
M.M. Heegstra

Like all elements of IT service management,
successful implementation of the service continuity
process can only be achieved with senior
management commitment and the support of all
members of the organization.
Ongoing maintenance of the recovery capability is
essential if it is to remain effective.
DevOps Process
M.M. Heegstra

Service continuity is an essential part of the warranty
(fitness for purpose) of a service.
If service continuity cannot be maintained and/or
restored in accordance with the requirements of the
business, then the business will not experience the
value that has been promised.
Without continuity the utility (fitness for purpose) of
the service cannot be accessed.
DevOps Process
M.M. Heegstra

Traditional IT service management (ITSM) best practice
such as ITIL looks heavyweight and not suited for the
quick processes of DevOps.
It is necessary to think about how to reduce
management workload.
DevOps Process
M.M. Heegstra

It is necessary to realign ITSM for DevOps, creating
light-weight ITSM which is strictly focuses on business
continuity with a set of minimum required information
MRI.
The MRI set for each organization depends on their
business

The pillars and foundation | TPS concept as foundation
Building a stream-lined supply chain of IT services is
difficult because there are many items and it is
necessary to change your mind-set from the familiar
existing development cycle and its methodologies.
DevOps Process
M.M. Heegstra

The concepts of TPS (Toyota Production
System), which includes JIT and automation, can
help.
JIT means building up a stream-lined supply
chain with one-piece flow.
And automation means automating as much as
possible and stopping the entire process when a
defect occurs.
DevOps Process
M.M. Heegstra

The process needs to be designed and staff
educated for the above two concepts.
The other key issue is the management cycle of
Development and Operation.
This needs to be changed to work in an Agile way
including synchronization between development
and operation on a weekly or daily basis.
