This deck introduces "cell-based" reference architecture, which is API-centric, cloud-native, and microservices-friendly. Further explains the role of APIs in the cell-based approach, as well as examine how real applications are built as cells. The deck covers metrics and approaches that can be used to measure the effectiveness of the architecture and explore how organizations can implement the cell approach.

INTEGRATION

2. INTEGRATION SUMMIT 2019
The Integration Imperative is Growing
Disaggregated architectures drive 50 billion endpoints, growing >1 trillion
CONSUMER DEMAND
Scale and agility are pushing
app disaggregation...
…that makes hybrid
integration the unspoken
challenge of all cloud
services

APIs create business agility
that fosters the rapid
business reconfiguration
necessary to continually
adapt to an unknown future
of constant change.”
~ Randy Heffner,
Forrester Research
...And APIs Are The Glue
All integration is becoming hybrid integration
“

4. Why are APIs important?
• An API is a business capability delivered over the Internet
to internal or external consumers
– Network accessible function
– Available using standard web protocols
– With well-defined interfaces
– Designed for access by third-parties
• A Managed API is:
– Actively advertised and subscribe-able
– Available with SLAs
– Secured, authenticated, authorized and protected
– Monitored and monetized with analytics

5. APIs are the products of the 21st Century
● APIs are how digital value is delivered
● Monetized either directly or indirectly
● Increasingly intermediated, traded and marketed
● Not just between organisations but within
organisations as well

6. StubHub is an API driven business

7. TfL is an adaptive business

8. Jaguar Land Rover is an API-driven business

9. Every Bank in Europe is now API-driven
Open Banking

10. Telkom Kenya is an API-driven business

A cloud-native programming language for microservices and APIs
● A compiled, transactional, statically and
strongly typed programming language with
textual and graphical syntaxes.
● Incorporates fundamental concepts of
distributed system integration
● Offers a type safe, concurrent
environment to implement microservices
with distributed transactions, reliable
messaging, stream processing, and
workflows.

21. The best architectures, requirements, and designs emerge from
self-organizing teams.
The Agile Manifesto
Agile processes promote sustainable development. The sponsors,
developers, and users should be able to maintain a constant pace
indefinitely.
Deliver working software frequently with a preference to the shorter
timescale.

26. A team which:
● Manages its own work
● Pulls work
● Doesn’t require “command and control”
● Communicates effectively with each other
● Is not afraid to ask questions
● Continuously evolves skills and capabilities
