devops has been popular in IT ever since emerging cloud technology. to make IT more agile, we need to keep setup goal and measure performance with adopting new cloud native tools.

6. The History of IT Organizational Systems
• 1960-1980s: Fragile “Cowboys”
– Optimize around the hardware
• 1990-2000s: Robust “ITIL”
– Optimize and protect around changes or traumas
• 2010s+: Resilient/Anti-Fragile “DevOps”
– Optimize on continuously improving the flow of value
Adapted from: Sergio Graziosi, Social Science Research Unit, Institute of Education, London

7. Origin of DevOps movement around 2009
• The Velocity Conference movement - “10 Deploys A Day”
• The “infrastructure as code” movement (Mark Burgess and Luke
Kanies)
• The “Agile infrastructure” movement (Andrew Shafer)
• The Agile system administration movement (Patrick DeBois)
• The Lean Startup movement by Eric Ries
• The continuous integration and release movement by Jez Humble
• The widespread availability of cloud and PaaS (platform as a
service) technologies

9. Defining DevOps
• DevOps is a professional movement to adopt modern roles,
cultural behaviors, practices, design patterns and technology
for acquiring, developing and operating software services with
increased agility and reliability.
• DevOps integrates developers and operations teams in order
to improve collaboration and productivity by automating
infrastructure, automating workflows and continuously measuring
application performance - rackspace -

10. Team culture for transformation

12. Agile and DevOps

13. What does DevOps-Oriented IT look like?
Increased Level of Optionality
Products, not projects
Features, changes are built, tested, deployed as an end to end flow
Most changes do not require dedicated analysis & approval
Quality is built in, changes are reversible
Production code is releasable at any time
All products are automatically test-driven, and testable in production
Software is runnable and portable on any cloud, any time
12 Factors: make development equivalent to production
Services can be swapped without affecting the whole
Microservices, APIs, cloud native scale-out

14. What does DevOps-Oriented IT look like?
Low-Cost, Sacrificial Elements
Teams are small, product-oriented, cross-functional
Releases are inexpensive, frequent, and fast
Deployments are automated, continuous, standardized
Servers are prefabricated, replicated, and disposable
Services are published, on demand, and resilient

15. DevOps Metrics in IT Performance
• Throughput Measures
– Deployment frequency
– Deployment Lead time
• Stability Measures
– Mean Time To Recover (MTTR)

17. Benchmark Company Performance: Faster, Higher
Quality, Higher Results 2015
Source - https://puppetlabs.com/2015-devops-report
30x more frequent deployments
60x better change success rate
168x faster mean time to recovery (MTTR)
200x faster lead times to change
200% more likely to exceed mission, profitability,
productivity goals
50% higher market capitalization growth over 3 years

18. Benchmark Company Performance: Faster, Higher
Quality, Higher Results 2016
Source – 2016_state_of_devops_report
30x => 200x more frequent deployments
60x better change success rate
168x => 24x faster mean time to recovery (MTTR)
200x => 2555x faster lead times to change
200% more likely to exceed mission, profitability,
productivity goals
50% higher market capitalization growth over 3 years

19. ROI of DevOps
• Savings
– Cost of excess rework = Technical staff size * Average salary *
benefits multiplier * percentage of technical staff time spent on
excess rework
– Cost of downtime = Deployment frequency * Change failure
rate * Mean time to recover * hourly cost of outage
• Value
– Do better from the saved engineering time

21. How to Implement

22. Three DevOps Principles
• Flow
• Feedback
• Continual Experimentation and Learning

23. The First Way: Systems Thinking
• Flow: Extending Delivery to Operations
– Continuous Delivery through to Production
– Treat Operations as a Platform – “done” is “running in production”

24. The Second Way: Amplify Feedback Loops
• Feedback: Extending Operations into Delivery
– Developers have insight into production
– Fail fast, fail often fail cheaply; Blameless post mortems
– Cloud Native Platform – deployments are cheap, servers are disposable

25. The Third Way: Culture of Continual
Experimentation And Learning
• Continuous Improvement:
– Iterative Experimentation & Learning throughout the organization
– Embed delivery knowledge into operations
▪ Cross-functional teams ; context carried throughout process
– Embed operations knowledge into delivery
▪ Delivery culture of “code for production quality”

26. How can an organization evolve towards a DevOps
Culture?
• Continuous Improvement Program
• Cloud Native Architecture & Technology
• Mapping Roles to Business Value
• Cloud Native Tools

27. Crafting a Continuous Improvement Program
• Metrics
– Track Production mean-time to recover (MTTR), lead times, rework
• Program
– Wardley maps, Value stream mapping, waste identification
– Iterative improvement and migration to cloud native technology
• Sync with Delivery Products
– Waste removal & reducing lead times every month
• Impact the Culture Iteratively:
– Top Down Mandate and Steering
– Bottom Up Empowerment and Decision Making
– Building Successes into a Force Multiplier

• Throughput Measures
– Deployment frequency
– Deployment Lead time
• Stability Measures
– Mean Time To Recover (MTTR)
