Define what is required 1. Deliver a version of business application 2. Provision, deploy and validate the Business App (including infra & middleware) to various environments (INT/VAL/PROD) 3. Notify operations of components deployed and and activate ops services / SLA required 4. Operate Business App components (supervision, patching, and other operations) 5. Provide functionality / value to business 6. Provide support and report SLA to business Rinse & Repeat…

21. CWIN16 – Going Cloud Native | September 2016 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 22 Dev/Ops is orthogonal to App/Infra Dev (E2E, Infra, m/w, Apps) Delivery (E2E, Infra, m/w, Apps) Business App (E2E, Infra, m/w, Apps) Ops (E2E, Infra, m/w, Apps) Cloud Native • Need Infra Dev and Ops • Infra becomes less about H/W and more about S/W • Infra people need to learn dev. E.g. SDI with chef or puppet and infrastructure creation with ARM templates or CloudFormation • Need Apps Dev and Ops • Apps becomes less about delivering to Ops and more about value in production • Apps people needs to know why their apps become slow, fail or get hacked. • Infra dev is quite different from app dev, even wrt common used languages, though there are some common principles and best practices

22. CWIN16 – Going Cloud Native | September 2016 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 23 WoW, Platforms & Tools - Dev Traditional • IT driven, Value defined by specifications. • Success defined by meeting milestones. • Focus on delivering to scedule and budget. • Waterfall principles with clear project phases and detailed planning schedules. • Customer represented indirectly by business representatives at specification and acceptance. Very slow production feedback from real users. Cloud Native • Business Driven, Value defined by business impact. • Success defined by velocity of putting value in production and by business metrics dashboards. • Focus on delivering value as quickly and cost effectively as possible, prioritizing work by these criteria. • Agile / Lean principles, mixing batch oriented models such as SCRUM and pull oriented models such as KANBAN. Voice of the customer required throughout the lifecycle. • Continuous Integration and Continuous Delivery essential. Dev

23. CWIN16 – Going Cloud Native | September 2016 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 24 WoW, Platforms & Tools - Delivery Delivery Traditional Infrastructure to support mostly manual provision, deploy and test processes • Outlook, Word, Excel • CMDB & Planning Tools • Test planning and report tools Ops define constraints and certain procedures. Dev define solution specific procedures and throws over the wall. Ops executes procedures… Cloud Native Infra, Platform & Tools to provision, deploy and test automatically • Provision and deploy tools: • Chef, Puppet, Ansible, Salt… • Cloud templates (ARM, CloudFormation, Heat…) • Docker Compose/Swarm, Mesos, Kubernetes… • Test automation tools • Selenium, MTM, HPALM, Gatling, Simian Army… Collaboration required on automation scripts between Dev&Ops, Apps&Infra

24. CWIN16 – Going Cloud Native | September 2016 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 25 Infra & Platforms – Business App Hosting Business App Traditional • Static Infra with long life requiring care • Limited supervision, mostly technical • Users and hackers find / report most latent problems Cloud Native • Dynamic Infra allowing auto-scaling, rolling updates, blue/green deployments… • Tendency towards short-lived, commodity, immutable infrastructure + services • Technical and business health supervision • User perspective SLA monitoring • Testing in production (e.g. Simian Army)

25. CWIN16 – Going Cloud Native | September 2016 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 26 WoW, Platforms & Tools - Ops Ops Traditional Operation of static Business App platform as defined at Delivery • Security, Health & Performance Supervision o H/W, Network, OS, middleware, app • Problem investigation, solving and routing… • Patching, Antivirus updates, Disk clean-up… Cloud Native Services largely the same as traditional but needs to work with automated deployments and dynamic infrastructure, and be more complete (see previous slide). How to know what to supervise with what SLA? How to distinguish between Dev, Val & Prod? If Prod is down during an upgrade with planned downtime, this should not create alerts.  Configuration of operations should be automated as part of delivery platform  Collaboration required on automation scripts between Dev&Ops Workaround: Operations defines constraints & prerequisites (supported and validated configurations including OS & middleware components with required agents and registration requirements) => Attn: RACI
