Capture
ProcessActuate
Data = Context information
• There are “smart solutions” in FIWARE overview
We focused on the process part
https://www.fiware.org/developers/

5. Copyright © 2019 TIS Inc. All rights reserved.
Our motivation
• When FIWARE application developers deploy a
business logic of the process part
• Issues
– FIWARE application developers
1. Need a lot of knowledge of infrastructure in order to
develop a business logic
2. Need to launch & configure various middleware, even
though to deploy a simple business logic

① I design an
architecture of
infrastructures
Our motivation
• If you would like to deploy a business logic for Orion

Our solution
Integrating Function as a Service(FaaS) capabilities in
FIWARE
• What is Function as a Service(FaaS)?
– FaaS is a platform allowing developers to run application without the
complexity of building and maintaining infrastructure
