The document outlines the development of a scalable, serverless DevOps pipeline for MAAS Global using technologies like Mocha, GitHub, and Travis CI. It details the goals of creating a cloud-based and mobile-first customer experience while avoiding closed architectures and exclusive deals. Additionally, it provides insights on serverless technology, deployment processes, testing protocols, and related resources.
Building a DevOps pipeline for Serverless by using Mocha, GitHub and Travis
- 1. Building a DevOps pipeline for Serverless by using Mocha, GitHub and Travis Sami Pippuri CTO James Nguyen Software Developer Maas Global
- 2. MaaS Global is building the future of mobility
- 3. System Goals Goals • Scalable, cloud-based • Mobile-first customer experience • Utilizing readymade cloud APIs • Infrastructure-as-code • Establish industry standard APIs where they don’t exist yet • Open for ecosystem partners • Create enthusiasm in the wider ecosystem – enable e.g. Universities and smaller developer houses around the world Non-Goals • Closed architecture or lock-ins (except AWS) • Exclusive deals • Server infrastructure • Intermediate, all- encompassing frameworks • Something for everybody
- 4. Loosely coupled Microservice API integrations – flexible inclusion into MaaS framework Routing Traffic Operator Traffic Operator Traffic Operator Transport Operator Weather Subscription Payment Identity Business Rules Customer Support Whim backend APIGW Whim Apps
- 5. Tech Stacks MaaS Core Lambda (Node.js 4.x, ES6) Serverless AWS Components* RESTAPIs Apps Backend Integrations MaaS Schemas MaaS-API SBUS * APIGW, S3, DynamoDB, RDS (psql), Route53, IoT, Cognito, CloudFront, CloudWatch, SNS, Kinesis, ML, SWF, IAM, ACM… SWF background processing SNS REST
- 6. Infrastructure – Serverless, cloud-native Whim Apps API Gatewayapi.maas.global MaaS Core MaaS TSP Trip Machine Identity Kinesis events Data Storage RDS Postgres
- 7. What is Serverless? - Is: - Open source. - Not really server-less. - A framework centralized in managing AWS Lambda, API Gateway and CloudFormation. - Robust, auto-scaling, fast and reliable. - Extensible in itself with a nice plugin system as well as having big supports from the community - Is not: - A server. - Helping you writing the code. - Yet possible to be run on-premise Check out at https://serverless.com/
- 8. Project Deployment Serverless autoinstall meta mocha Webpack Base toolstack Travis CI PROD (Alpha) Unit & integration testing Deploy to stages (4 of them) PROD DEV TEST Continuous Deployment (!) Test harness Dep sripts Local test harness
- 9. Detailed workflow Feature development * Code review ** Open pull request ** Merge onto master ** Release alpha ** Release production ** Feature testing * Field test *** Smoke tests *** Dev Developer’s fork Test Master branch Alpha Alpha branch Prod Prod branch Tagging candidates Documenting releases Change log Bug fixes * *Manual testing ** Automated test with Travis *** Application test
- 10. Auto deployment in action!
