DEVOPS

• DevOps is a combination of two words Development
  and Operations.
• It is neither an application nor a tool it is a
  method to promote development and Operation
  process collaboratively.
• DevOps helps to increases an organization's speed
  to deliver applications and services.

4
DEVOPS LIFECYCLE

• Development
• Testing
• Integration
• Deployment
• Monitoring

5
WHERE DID DEVOPS COME FROM?

• ESM (Enterprise Systems Management)
• Administrators brought the key ESM practices to
  DevOps like configuration management, automated
  provisioning, system monitoring, and the
  toolchain approach, etc.
• Agile Development
• DevOps can be considered as an outgrowth of the
  Agile. It is simply extending the Agile
  principles beyond boundaries of the code to the
  entire delivered services.

6
DEVOPS ADVANTAGES

• Predictability
• Maintainability
• Improved Quality
• Lower Risk
• Cost Efficient
• Stability
• Streamlined Delivery Process

7
AGILE

• Agile software development method emphasis on
  iterative, incremental, and evolutionary
  development.
• Agile refers to an iterative approach which
  focuses on collaboration, customer feedback, and
  small, rapid releases.
• Agile method is to give priority to the working
  system over complete documentation. It is ideal
  when you're flexible and responsive.

8
AGILE CORE VALUES

• Individual and team interactions over processes
  and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan

DEVOPS AND AGILE ARE ALTERING THE WAY WE MEASURE
QUALITY

• Accelerate software delivery
• Enhance the ability to manage changing priorities
• Increase productivity
• Improve business/IT alignment
• Enhance software quality
• Enhance delivery predictability
• Improve project visibility
• Reduce project risk

11
DEVOPS AND AGILE ARE ALTERING THE WAY WE MEASURE
QUALITY

• Improve team morale
• Improve engineering discipline
• Reduce project cost
• Increase software maintainability
• Better manage a distributed team  
• Improve software availability

12
THE TESTING PRACTICES THAT WILL TRANSFORM YOUR
TESTING

• Rely Only on a Controlled Security Environment
  for Testing
• Carry Tests Throughout the Software Development
  Cycle
• Break Tests in Small Fractions
• Write Tests for Maximum Coverage
• Carry Regression Tests
• Programmers Should Not Write Tests
• Note and Report All Tests
• Clean the Test Code Prior to Final Release of
  Software Product

13
THE TESTING PRACTICES THAT WILL TRANSFORM YOUR
TESTING

• Isolate the Application from Developers
• Customize Testing
• Accumulated Skilled Testers
• Build a Target Operating Model for Testing
• Have a Mix of In-house and Offshore Teams

14
DEVOPS METRICS

• Deployment frequency
• Change volume
• Deployment time
• Lead time
• Customer tickets
• Automated test pass
• Defect escape rate
• Availability

15
DEVOPS METRICS

• Service level agreements
• Failed deployments
• Error rates
• Application usage and traffic
• Application performance
• Mean time to detection (MTTD)
• Mean time to recovery (MTTR)

16
AGILE PROCESS METRICS

• Leadtime
• Cycle time
• Team velocity
• Open/close rates
• Mean time between failures (MTBF)
• Mean time to recover/repair (MTTR)
• Application crash rate
• Endpoint incidents

17
DEVOPS AND AGILE QUALITY METRICS THAT SEPARATE
LEADERS FROM THE PACK

• They are transforming software testing into
  Continuous testing by adopting 5 core practices,
  such as automating end-to-end functional testing
  and integrating testers into cross-functional
  teams.
• They are almost twice as likely to consider
  automating the software quality process to be a
  "critical business differentiator"
• They are significantly more likely to have high
  levels of automation for key testing and QA
  processes
• Focus on contextual metrics
• Measure user experience across end to end
  transaction
