DevOps
promove colaboração entre Dev + Ops de modo a aumentar a cooperação
através da entrega contínua sem sacrificar a qualidade de software em
produção
DevOps é um conjunto de
princípios, métodos e tecnologias para
lidar com o desafio de liberar
rapidamente a evolução do software
de alta qualidade desde o
desenvolvimento até a produção,
onde tudo se torna programável:
aplicação, testes e Infra-estrutura.

Mas afinal, como fazemos hoje?
Any organization that designs a system (defined broadly) will produce a design
whose structure is a copy of the organization's communication structure.
-- Melvyn Conway, 1967

Devops é uma mudança
cultural que fomenta comunicação,
colaboração e alinhamento de
objetivos entre as diversas áreas de
tecnologia da informação
▪ Entrega contínua via sprints
▪ Integra processos, pessoas e
ferramentas visando agilidade ao
negócio e minimizando retrabalhos.
▪ É a interseção produtiva da cooperação
entre times multidisciplinares;
DEVOPS enfatiza:
 Flexibilidade
 Agilidade
 Automação
 Colaboração
 Comunicação
 Cooperação entre equipes
 Responsabilidade

 TDD – Abordagem Test Driven Deployment já no
levantamento de requerimentos
 Sprints de grupos de funcionalidades
 Ambientes Dev, QA e Produção permitindo a
integração contínua
 Testes Automatizados
 Procedimentos padronizados e automatizados em
todas as etapas do processo (incluindo promoção a
produção)
 Orquestração dos ambientes incluindo nuvens híbridas
 KPIs medindo e monitorando as etapas do processo

•Dev & Ops are part of
multidisciplinary delivery
team and share
responsibilities
• Time-to-market and ROI is
benchmarked
•Dev & Ops collaborate to
accelerate delivery cycle,
sharing knowledge and
feedbacks
• KPIs measure delivery
process efficiency
• Dev & Ops are striving to
ensure end-to-end delivery
process and limit non-added
value task
• Workflows and tools are
integrated
•Dev & Ops work together
when it is required
•Delivery process interfaces
are managed (eg: release
notes)
• Organization is siloed ; Dev
& Ops objectives and
practices strongly differ
•Operations are involved at
the end of the projects /
deliveries
•Continuous integration,
fully automated: every day
the system’s components
are integrated, analyzed,
measured and tested
together
• Integration tests are fully
automated and performed
as often as possible to
detect bugs
•Everyone commits to the
baseline every day
•The integration
environment is used on a
regular basis to develop,
test and deploy
•Integration tests are mainly
automated

of production env.) is
available to test all the
components of the release
at least once together
before the roll out
•Integration tests are lately
and partially done
•Lately and partially
integrated in the pre-
production environment
•Tests are fully automated
• Continuous testing +
efficient environment
provisioning reduce test
cycle and failures impacts
•Test driven deployment
(TDD) and automation is the
rule
•Load testing is integrated

•Automated tests are
initiated with a focus on
unit testing
•Test phases anticipated in
the project plan
•Tests require mainly
manual activities
•Tests partially written and
done at the end of the
project (bottleneck effects)
•Continuous end-to-end
deployment implemented
•Tools used to monitor
deployment performance
•One single, repeatable
deployment process
defined and tested over the
multiple environments
•Rollback is automated
•Roll out of applications is
automated (performed by a
‘push button’ )
•Deployment is repeatable
and automatically executed
•Effort made to automate
and define deployment
standards across the
delivery phases
•Self service deployment to
development and test
•Deployments are realized
manually or through
separate scripts for
installations of applications
and DB per environments
•Continuous and automated
provisioning with self
service portal implemented
• Virtualized and as a service
infrastructure
•Environment can be
created and torn down by a
push of the button (end-to-
end provisioning approach)
•Operating system is
virtualized
• Environments are
standardized
• Several tools are used to
provision and configure an
environment
• Scripted installations per
component for each server
• Request and configuration
