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

1. The Composable Enterprise

INTEGRATION

2. APIs are the
products of the 21st
Century

5. Reproducible,
Fungible,
Reliable

8. Today, most
APIs are direct
from producer
to consumer

9. But not all APIs are direct from
producer to consumer

In the first 18 months, 2500 developers created 3300 apps

real-time analysis
● Step-up authentication
● Adaptive authentication

21. APIs are important
internally as well as
externally

22. 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

23. 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
“

24. Every
developer is
an integration
developer

25. Every generalisation
is wrong….

26. Every
developer is
an integration
developer

27. Ballerina is the first programming language
built around APIs

28. Ballerina - code and visual syntax in sync

32. 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.

46. Biology is
fundamentally the
study of
complex systems

48. The cell is the basic
structural, functional,
and biological unit of
all known living
organisms

54. Self-contained
Deployable as a unit
API Centric
Data plane and control plane
Cells are the building blocks of a composable
enterprise

55. The interface to a cell needs
to be treated as a
product

58. Cellery 0.4.0 released

61. A cellular architecture
with API-based products
creates a
Composable Enterprise
