3. What does a Smart City Look Like?

4. 4
Our Conception

5. 5
Our Reality

6. 6
3.9b people live in cities today

7. 7
By 2050, we’ll add another 2.5b people

8. 8
We need to create sustainable cities

9. 9
We need to use technology to help us

10. 10
We don’t live in Tomorrowland

11. 11
We live here

12. The good news:
the Technology of Today can
build smart cities.
12

13. 13
 City-wide WiFi
 City App to report issues
 Open-Data Initiatives to
share data with the public
 Most importantly, an
adaptive IT department
A Smart City Should Have…

Let’s learn how.

15. A Model Application: MemCity
Capturing data from 1.4 million households
Total AWS hardware costs at $2.35 per hour

20. The “Real-Time Trinity”

21. Designing the Ideal Real-Time Pipeline
Message Queue Transformation Speed/Serving Layer
End-to-End Data Pipeline Under One Second
21

22.  A high-throughput
distributed messaging
system
 Publish and subscribe to
Kafka “topics”
 Centralized data transport
for the organization
Kafka
22

23.  In-memory execution
engine
 High level operators for
procedural and
programmatic analytics
 Faster than MapReduce
Spark
23

24.  In-memory, distributed
database
 Full transactions and
complete durability
 Enable real-time,
performant applications
