9. Data is derived from Events...
Events are happening everywhere, all the time
● In apps, cars, appliances, servers and even in our brains
With so many devices online
● It’s becoming easier to collect data from just about anywhere

EDA drives Real
Time Data
Movement… …data in motion
unlocks the value of
data
EDA transforms batch
delivery & periodic
polling into real-time
streams of events…
•Continuous
awareness
•Agility,
flexibility,
scalability
…streams of events
enables digital
decoupling of the
enterprise

12. What is EDA and how does it work?
In modern businesses,
when something happens…
(i.e. an event occurs)
High temp
detected in
drive motor
Passenger
boards flight
a little late
Customer buys
certain product
Decrement in-store and online
Request replenish from stock room
Update points, reward for new level
And (frequently) do
something about it
Degrade or cease operation
Notify security to indicate closure
Dispatch repair technician
Update expected departure time
Rebook passengers missing connection
Change passenger status, alert family
Applications need
to know about it

EDA allows your business to operate in real-time with Digital Decoupling

14. EDA allows your business to operate in real-time with Digital Decoupling
EDA Way
Decoupled  Dynamic
One-to-Many
Easy to Adaptable and Scale
The Impossibility of Infinite
Integration
Hard-coded or point-to-point
connections between hundreds
of applications and data stores
is unsustainable

16. What are
API Products and Event API’s?

17. API Products Help Others
Consume Your Business Capabilities
• Bundles of related APIs that meet the
needs of developers who serve
different business functions
• Produced, shared and consumed
through a developer portal
• Managed by a product manager -
roadmap, price, lifecycle
Source: Gartner “Kick-Start Your Composable Business Journey With 2 Key Strategies”,
15 Dec 2020, Yefim Natis, Mark O’Neill, John Santoro

18. “Event-driven APIs are a new style of
API that uses a subscription “push”
model rather than the request-
response model of conventional
RESTful APIs.
Architects must develop new
approaches to mediating and
governing event-driven APIs,
because API management platforms
designed only for RESTful APIs may
not be sufficient.”
Source: Gartner “Emerging Technologies and Trends Impact Radar: IT
Services”, 24 Sept 2020, Twiggy Lo, Brendan Williams

29. Closing
• EDA is being adopted as the architecture for modern enterprises in the era
of disruption
• Treat Events as first-class citizens – Events need their own infrastructure
• EDA use cases – Real time business, Digitisation, IoT, Hybrid Cloud
• Get the foundations right – Transactional (Operational) and Analytical (data)
have different needs, so use the right building blocks
• Understand different Event Brokers – Gartner Research, EDA Summit.
• Prepare for the unknown – True decoupling – Location/Environment (Multi-
cloud) Technology & Vendor (Standards) Pace (Legacy) gives agility and
prevents future lock in.
• Adopt governance early
• Hands on workshop tomorrow
• EDA Summit
