This document discusses open APIs in financial services and a cloud-native approach. It covers how open APIs allow for new functionalities, partnerships, and innovation. A cloud-native approach using microservices and containerization is presented as a modern architecture for building APIs. Examples of Red Hat products and solutions for open banking APIs and sandboxes are also provided. The presentation concludes with a Q&A section and links to additional resources.

FSI services should offer an
exceptional end-to-end
personalized seamless
customer journey to clients,
leveraging technology to
create this experience.
FSI organizations have tons
of data about customers.
Using big data, cloud, and
AI to generate insights and
knowledge from this data will
allow companies to improve,
innovate, be proactive, and
develop new business
models.
All communications must
maintain and deliver the
same experience to clients,
keeping the customer
satisfied and connected.
Delivering early, and
continuous, value to
customers, accepting
change, and failure, are just
some of the Agile values
that builds a customer
centric culture.

doesn't sleep and it's able to
provide a stable, and
reliable, experience any

6. Innovation
What is the Impact of Open APIs
Become Agile to Embrace Changes
More companies, more offers… Consumer data
sharing frameworks will force companies to be more
competitive if they want to stand out for clients
Competitivity
New platforms to contact clients
Channels
To support these new operations, and the data
created/analyzed, banks will need to innovate while
adopting new technologies
Fast and cheap
The process it's cheaper and faster because it has
less participants
New Partners
Other companies can offer banks services using the
banks partner APIs. These APIs can be monetized
and these connections can give banks the freedom
to work at their core systems.
