This deck introduces the composable enterprise and how it's created.

INTEGRATION

2. 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
SUPPLIERS DISAGGREGATE ARCHITECTURE TO MEET DEMAND

3. 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. Every
developer is
an integration
developer

5. Every generalisation
is wrong….

6. Every

7. Agile - Developer Flow

8. The wrong
technology stack
interrupts flow

9. Ballerina is the first programming language
built around APIs

10. Ballerina - code and visual syntax in sync

14. 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

15. 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

17. What about security?
● Encryption, Tokens, SSO
● Multi-factor authentication
● Fraud detection and
real-time analysis
● Step-up authentication
● Adaptive authentication

In the first 18 months, 2500 developers created 3300 apps

21. APIs are important
internally as well as
externally

23. 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.

Organizations which design systems are
constrained to produce designs which are copies of
the communication structures of these
organizations.
