MaaS Global is building the future of mobility
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
Loosely coupled Microservice API integrations – flexible inclusion into MaaS framework

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
