DevOpsDesenvolvimento de Software e Operação de TI


DevOps Drivers e Benefícios

Redução no tempo de

interrupção operacional e

de implantação

Redução de erros

“humanos”

Suportar a pressão por

entregas de alta

qualidade e mais

rapidamente

Drivers

Implantação acelerada com automatização

Colaboração entre os

departamentos (Dev, QA, TI

Operação)

Redução nos gastos com

“retrabalho”

Redução do tempo de ciclo de

TI

Benefícios


DevOps ROI – Retorno do Investimento

66% das empresas adotaram ou planejam adotar métodos DevOps.

Crescimento em até 3X em atualizações de aplicativos ou

implantações.

21% de redução no tempo lidando com casos de suporte.

37% de redução no tempo “apagando incêndios”.

50% menos falhas.

30% mais rápido na entrega de novas funcionalidades.

33% de aumento em melhoria no ambiente de infraestrutura


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.


DevOps 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

Level 2Managed

Level 3Defined

Level 4Measured

Level 5Optimized

• 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

• An integration env. (clone 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 early in the dev. cycle

• Automated tests are generalized to the downstream phases

• Tests design + execution early in the delivery cycle (Dev-Test-Ops approach)

• 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 management process is initialized

• Manual installation and configuration of environments with no standards / patterns

• Request Management process is not normalized
