Agenda
1. DevOps is a methodology or a role?
2. DevOps is a philosophy, a concept or a culture?
3. DevOps is a developer specialist who understands infra/operations?
4. Or it is a sysadmin who understands code develop?
5. Is a position? Or it is a department?
6. DevOps only works on startups or fit on corporate environment too?
What is DevOps?
Lets try choose the best answer for that
DevOps is NOT just it:
Certification
Tools
Role
Dev Team
Developers, UX/CX analyst, QA, Architects, SMs
Measured on the features
they deliver to users
INCREASE THE BUSINESS
as many deploys as needed
Dev “vs” Ops (1/4)
Ops Team
System administrators, Operations staff,Release engineers, DBAs, Network
engineers, Security professionals,...
Measured on the stability of the system.
PROTECT THE BUSINESS
keep services running
few deploy as possible
Finger Pointing
& tension
between introducing
new features and stability

Dev Team Ops Team
Bundling the code, packaging the product, provisioning the environment, and coordinating with the operations staff
Consistent, reliable and repeatable automated deployments, human error and the need for ‘rockstar firefighters’ are reduced

So… DevOps is ... (1/3)
Disclaimer: there is no definitive answer. Yet.
It’s a still-evolving movement
DevOps is the practice of operations and development engineers participating
together in the entire service lifecycle, from design through the development
process to production support.
So… DevOps is ... (2/3)
DevOps is a set of practices and cultural changes — supported by the right tools —
that creates an automated software delivery pipeline, enabling organizations to
win, serve, and retain consumers.

It’s a still-evolving movement
So… DevOps is ... (3/3)
The implementation of DevOps is not simply about the deployment of new IT methodologies. It must be treated as a company-wide
transformation—one that incorporates process and
governance considerations as well as technology-related ones.

T
1. Automated infrastructure tools - provisioning tools. The main goal is to deploy and maintain not only applications, but also quick controlled infrastructure based on “IAAC” - Infrastructure As A Code
(e.g. Chef , Puppet, Ansible, Docker, Vagrant)
2. Automated build /deploy tools - continuous integration / deployment
New version of the application on anch code change (commit).
(e.g Jenkins, Travis)
3. Automated QA tools - functional, integration and regression tests tools
combined to quality assurance.
(e.g jUnit, Cucumber, Selenion, Cbash, Sonar, CodeReview, IBM Workbench)
DevOps - Tools
T
4. Monitoring tools - availability, performance and security Monitoring. Consolidação e centralização de logs.
(e.g. New Relic, Zabbix , Splunk, Logstash, Graylog)
5. Source Control - source code management
(e.g. GIT, SVN, IBM ClearCase, Perforce, etc)
6. Bug Tracker - issues management
(e.g. JIRA, Mantis, Redmine, IBM Rational Team Concert)
7. Cloud Computing- SaaS -> PaaS -> IaaS - services availability and scalability
(e.g. Amazon, Force.com, Microsoft Azure, Google Apps Engine)
