How to speed up DevOps with ChatOps

Discerning feedback from the customer and questions like “Why DevOps?” and “Why does that matter to me?”, “And why do I have to move to the cloud?”…
Many companies have problems adopting new tools and agile methods because their staff is often suspicious and doesn't understand why they should change something if it still works the way it is. Their motto is: "Never change a running system" and "We've always done it that way".
Within this talk we demonstrated how quickly and easily a ChatOps showcase can be realized with the help of AWS Lambda and the serverless framework. You'll see which advantages this leads to and how it can improve your everyday workflow. And – of course – how it can blow the concerns of your customers away.

7. What is DevOps? Eliminating low-value activities and moving quickly, continuous improvement and embracing failure Lean Sharing responsibility and success will go a long way toward bridging the divide between Dev and Ops Sharing It’s hard to prove your continuous improvement efforts are actually improving anything without data Measurement Investing in automation eliminates repetitive manual work, yields repeatable processes, and creates reliable systems Automation Cross-functional collaboration, shared responsibility, transparency and faster feedback Culture 02 04 01 03 05 7 ChatOps Showcase – DevOps beschleunigen mit ChatOps | Selina Magnin and Tobias Unger | Digital Xchange 2019
8. What is ChatOps? Communication – The basis of todays businesses Communication is the exchange or transmission of information. Transmission means that distances can be overcome. These two sentences contain several essential information and challenges we are confronted with in the day-to-day business of software development and operation. collaborate share trust understand build 8 ChatOps Showcase – DevOps beschleunigen mit ChatOps | Selina Magnin and Tobias Unger | Digital Xchange 2019
9. 9 Services / Bullet Points One System All information, project-relevant documents and processes in one place. Notify & Share Every step and the corresponding feedback is automatically persisted in the chat. Persist & Document Everything is persisted and documented immediately in the chat. No increased effort for the dev. Control & Interact The bot can be seen as a shared shell where all chat participants can enter commands. Use the chat also as an interface and control mechanism for other systems. 9 What is ChatOps?

25. 25 Lessons Learnt ChatOpsShowcase
26. Lessons Learned 26 The DevOps Processes are key! Rather use simple interaction patterns (e.g. buttons) than implementing natural language support. Bots should only be used if user interaction is necessary. Everything that can be automated should be automated. The robot should support platforms, tools and devices that are known and useful to the user. Don't introduce any additional tools just for the bot. 01 02 03 Simple Interactions Automation first Support of Tools Multitenancy support is mostly necessary for development and runtime. Try to cover that first! 04 Multitenancy First ChatOps Showcase – DevOps beschleunigen mit ChatOps | Selina Magnin and Tobias Unger | Digital Xchange 2019
