Node.js Café 7.12.2016 presentation by James & Sami / MaaS Global Life on the bleeding edge is not always easy. In building the Whim service with Serverless, we ended up building a DevOps pipeline, too. Here we’ll show how it works.

1. Building a DevOps pipeline
for Serverless by using
Mocha, GitHub and Travis

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

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
