- 4. THE IT CHALLENGE DevOps India Summit 2018 | 3 Waterfall – Long phases Many Silos – Functional areas Bureaucracy Can’t respond fast to changes Delays Quality Problems Painful releases Iterations Cross-functional / Autonomous teams Lean Respond fast to changes Better Quality Feedbacks Continuous Delivery Time to Market Competitiveness
- 5. ACCEPT! THERE IS NO MAGIC DevOps India Summit 2018 | 4 IT TAKES TIME Don’t look for revolutionary, look for evolutionary. SUCCEED FIRST Experiment first, prove the benefits and then scale (inspecting and adapting). OLD & NEW COEXISTS Don’t force to replace. Don’t judge the old. Engage for improvements. REFERENCES x MODELS Consider models as references. Find your own way to continuous delivery. With your organization’s people.
- 6. 1st ALLOWED TO EXPERIMENT CHANGE AN AREA? CREATE A NEW AREA? CREATE A NEW COMPANY (STARTUP LIKE)? AGILE/LEAN PRINCIPLES + DEVOPS PRACTICES + DIFFERENT CULTURE • high executive decision – BUY IN • AUTONOMY – Free from “This is the way we work in this company” • to PROVE that works DevOps India Summit 2018 | 5 WILL NEED: But…we have to bring results interacting with the traditional
- 7. 2nd A TEAM TO IGNITE CONTINUOUS DELIVERY DevOps India Summit 2018 | 6 • Help to find better links between areas – Lean Release Process • Consider the whole and bring them closer to development time (Business, QA, Operations, Security…) • Provide automation, patterns and tool engine to support CD • Propose scalable and reliable solutions/architectures • Coaching – help teams to increase their maturity level in different DevOps capabilities • Engage to a continuous improvement mindset • Experiment, then share best practices to the entire company ** http://web.devopstopologies.com/
- 8. 3rd ARCHITECTURE TO SCALE AS SOON YOU PROVE THE BENEFITS, YOU’LL BE ASKED TO SCALE • Simple to use (Developer Experience) • Consider involved areas requirements (collaboration) • Infrastructure to scale – Elastic, if possible. If not, projections • Standardized pipelines – changes can be rapidly applied; better governance • Flexibility – you may have different pipeline “flavours” • Intelligent use of resources – on demand slaves (builds) • Measure your CI/CD – Inspect and Adapt DevOps India Summit 2018 | 7 57 applications with CI/CD in 17 months – +700 jobs
- 9. BUILD / TEST RELEASE DEPLOY MONITOR CODE CONTINUOUS INTEGRATION ~400 Builds/day CODE QUALITY INSPECTION AUTOMATED TESTS PACKAGE (CONTAINER) ~40s - 10min Every release is tagged and stored in a binary repository, facilitating ROLLBACKS CONTINUOUS DELIVERY – fully automated deploys ~10 releases/day ~4s – 7min 1 2 3 4 CONTINUOUS MONITORING improvements based on metrics 5 CI/CD ARCHITECTURE - EXAMPLE DevOps India Summit 2018 | 8
- 10. 4th IT’S A LEARNING PROCESS – PEOPLE FIRST AUTOMATION IS A KEY TO CONTINUOUS DELIVERY, BUT NOT SUFFICIENT… DevOps India Summit 2018 | 9 • People have to be part of the change • Evangelize / Advocate – Blameless; Empathy; Collaboration; Continuous Improvement Mindset • Coach – Help them achieve better states by themselves 488 85 3741 % Cobertura Antes Depois 0 <= c <= 40 14 6 40 < c <= 80 5 5 c > 80 4 12
- 11. CONCLUSION • Autonomy for experimentation - the agile environment separated from the traditional part of the company was essential to bring innovation. • Empowerment – a DevOps team with top down support made it possible to communicate with other areas in highly hierarchized companies. • Standardized CI/CD Architecture - easy to use, scalable and best patterns. • Sharing behavior – include traditional areas in each one of the initiatives, listening and respecting them, and supporting them to achieve a continuous delivery status. SCALE TO ENTIRE COMPANY DevOps India Summit 2018 | 10
- 12. CONCLUSION • It’s easier to scale tech then teams – overwhelmed DevOps team points to an model with many DevOps cells (keeping them closer to the teams supported by them). • Keep improving and sharing – as you scale, be careful to not just support what exists. Reserve capacity to evolve! • Whatever you do, try to do in an organic way. • Continuous engagement – this is the biggest challenge! People come and go. Companies changes their organizational structure. Keep both botton up and top down initiatives to engage people. CRITICAL DevOps India Summit 2018 | 11
