This document summarizes a presentation on the journey towards continuous delivery for an e-commerce company's shop platform and mobile app. It discusses moving to a microservices architecture with a page assembler component. Key aspects covered include deploying microservices in real-time using Docker containers and a Jenkins pipeline, as well as connecting the mobile app through a public API. The presentation then focuses on the process for the mobile app, including using a vertical team structure and implementing continuous delivery through automated testing, deployment, and orchestration pipelines. Lessons learned and next steps are also outlined. Interactive discussion groups after a break will cover experiences with continuous delivery for mobile, platform as a service, and integrating components in a continuous delivery pipeline.

29. Learnt Lessons
• iOS CI only over a Mac.
• Use match to make your life easier with iOS certificates.
• Jenkins needs to access the user mac keychain.
• Android emulator + docker in a Mac not compatible.
• Genymotion rocks.
• Automate as much as possible the setup of your environment.

30. Next steps
• Dockerize Jenkins & create more slaves using docker.
• Automatize Android native app deployment in the market.
• Test Rail integration with Appium, Frisby JS, Gatling tests results.
• Monitoring Panel (MS & Apps).
• Execute tests on a device farm.
