Improve the Development Process with DevOps Practices

1. Improve the
Development Process
with DevOps Practices
• Vadym Fedorov

2. Who am I?
• Vadym Fedorov < vfedorov@softserveinc.com >
• Role: Solutions Architect
• Company: SoftServe
• Specialization: Development of the Enterprise
Applications in the IT operations management
segment.
• Technologies and tools: .NET, Python…

3. Non-stop Battle: Angry Dev vs Ops
DEV OPS

4. Pandora’s Box
• There is no single responsible person who would
manage the product from definition of business
requirements to the product release.
• The Dev and Ops teams have different success
metrics.
• Lack of communication between the Dev and
Ops teams.
• There is a difference between development and
target environment configurations.
• Slow and long delivery processes with
unpredictable delivery date.

6. Evaluate the Current
State
• The project maturity model

7. Key Indicator
• Project Portability, i.e. an ability to move the
project between different environments and
teams.
• Project Continuity ensures that a project can be
successfully completed even if a team changes.
• Time-to-market and cost requires control over
your project development, since these are critical
elements that directly affect revenue and your
position in the market. So make sure you are
using effective ways to optimize this business
driver.

8. The Project Maturity Model

9. Ad-hoc
• Deployment or development documentation is
often outdated if present at all
• Developers manage 3rd-party dependencies
manually
• No standardized development workplace
configuration
• Deployment on staging and production
environment is fulfilled manually
• Lack of knowledge sharing
• Low repeatability of the deployment process
• Launching a new team requires significant efforts

10. Defined
• Developers keep project documentation and related configuration up-to-
date
• Dependencies are managed with a native package platform (PIP, NPM,
NuGet, etc.)
• Documents describe development environment configuration or prebuild
virtual machine with a configured development environment
• Team may use a Build and Continuous Integration System, however, the
changes in the configuration are applied manually
• Knowledge transfer from the development team to the operational team,
and between development teams is performed verbally or via
documentation
• Repeatability of the deployment process is satisfactory
• Launching a new team requires significant effort

11. Repeatable
• Regular validation of the deployment and development
documentation
• Developers work on an up to date development environment
• Environment configuration and deployment procedures are
documented in the form of a code deployed to source control
• It is possible to track changes: who and when introduced any
changes, what version was deployed, on whichdevelopers’
workstation, and other staging and production environment
variables
• Team uses virtualization
• High repeatability of the deployment process
• Launching a new team does not require significant effort

12. Managed
• Managed is the highest level of the project
state when development and production
environments are aligned with
configuration as much as possible:
 The number of manual steps on environment
deployment is as low as possible

13. What can be changed
to improve?

14. Organizational Changes
• There should be one, and only one, manager
responsible for a product or feature development
from A to Z: from the stage of requirement
gathering to the release date.
• The development and operational teams need to
share common success indicators focused on the
delivery result.
• The operations team needs to define requirements
for monitoring, log management and disaster
recovery, as well as help the development team
design a solution that complies with these
requirements.

18. Development Process Changes
• The development team should use a
development environment that’s as close
to the target environment as possible.
• To apply an “infrastructure as code”
approach.
• To automate quality control and
acceptance testing

19. “Infrastructure as Code” Approach
Virtual
Machine
Provisioner
Scripts
Vagrant
Code
Virtual
Machine
Provisioner
Scripts
Production
Code
Same OS, same configuration and same versions
Ops or DevOps
Dev
Deploy

20. Delivery Pipeline
“Build Stage”
• Execute Unit Test
• Code Analysis
• Build deployment package
Automated
Acceptance
Testing
Manual testing
• Key showcases
• Exploratory testing
Release
Commit Deploy
Unit & Integration Tests
Functional Tests
Production Monitoring

21. Tools That are Good to Know
• Vagrant: https://docs.vagrantup.com/v2/
• Configuration Management and Provisioners:
 Chef: https://www.chef.io/chef/
 Puppet: https://puppetlabs.com/
 Ansible: http://www.ansible.com/home
• Log management and Monitoring
 Newrelic: http://newrelic.com/
 Loggly: https://www.loggly.com/
 Logstash: https://www.elastic.co/products/logstash
• Testing:
 JMeter: http://jmeter.apache.org/
 Selenium: http://www.seleniumhq.org/

22. Benefits
• Avoidance of the human factor
• Improvement of the Quality and
Repeatability
• Saved Time and Reduced Risks
