How is #ServerlessTO different?
2
… But if you’re looking for a server to put in the
cloud you probably made the first major mistake,
because the cloud is NOT about infrastructure –
it's about changing the way you build & deploy
applications. Cloud is a different lifestyle, not a
replacement for your data center and no CIO
ever needed another data center…
… Try to follow the logic that you shouldn't run
applications you didn't build.
– Gregor Hohpe, CxO Advisor
Everybody's going to the cloud…

3.
Why we do what we do?
3
Serverless is New Agile
Serverless Dev (gluing
other people’s APIs and
managed services)
We're obsessed by
creating business value
(meaningful MVPs,
products) and helping
Startups
We build bridges
between Serverless
Community (“Dev leg”),
and Front-end & Voice-
First folks (“UX leg”),
and empower UX
developers
Achieve agility NOT by
“sprinting” faster (like in
Scrum), but by working
smarter (by using
bigger building blocks
and less Ops)

B2C E-commerce

16.
Section
Business Problem
Our client is an innovative biopharmaceutical
company focused on the development,
manufacturing and commercialization of organic
and sustainable plant-derived cannabinoid-based
products.

17.
Section
Business Problem
The problem is that many current out of the box
solution providers refuse to work with them.
Thus, we need to roll a custom e-commerce solution for them!

18.
Section
Enter Serverless
Use a headless JAMstack
solution to minimize
development and
maintenance costs.

● CMS - Contentful
● E-commerce engine - Moltin
● Fulfillment partner - Percos
● Payment processor - PayU

A few gotchas
Internationalization (i18n)
Be careful how you structure your content
and where it’s stored. Depending on the
structure of your client’s teams, they may
require different tools (eg. merchandising vs
product).
Authorship Experience Re-compilation of the site
A few different concerns come up here. First,
integrating third-party sources of content.
Second, preview. Third, hard-coded content.
Do your best to manage recompilation
times. You should do your best to
understand what should be moved to a
data fetch post-render.

22.
Section
Results
The site is live and accepting orders in multiple
locales around the world, integrated with their
in-store supply chain.

Enterprise Retail Platform

24.
Enterprise Retail Platform
Business Problem
Our client is a large Canadian luxury clothing
retailer.
They were mired in legacy systems with an inability to innovate and
deploy new e-commerce and omni-channel experiences. How did we
help them build a platform on which to move forward?

25.

Enterprise Retail Platform
Integration Problem
Many sources of data, multiple
domain models
Accounting, ERP, Loyalty, CRM, Data Science,
Merchandising, etc

26.
Enterprise Retail Platform
Two sources of inspiration
Domain-Driven Design Joel Crabb’s Retail Platform
Protect our domain model and concepts from
the upstream models using a bubble context
separated by an Anti-Corruption Layer (ACL).
Joel Crabb (VP Architecture and Chief Architect,
Target) proposed a model for a Retail Platform
as an event-driven system, with read-only APIs
for primitives like Carts and Product.

27.
Enterprise Retail Platform
Bubble Context
Allows you to create
your own clean
domain model
Decouples you from
the underlying data
sources
Increases the pace
of innovation over
time

28.
Enterprise Retail Platform
[A retail platform] is a set of primitive APIs and
Services that represent the data, processes and
business logic required to complete customer
transactions
Joel Crabb

29.
Image goes here
Enterprise Retail Platform
Architecture
Streaming ETL powered by IBM
Event Streams (Apache Kafka)
and Functions (Apache
OpenWhisk) acts as an ACL
feeding data into a read-only
set of APIs for retail primitives.
A GraphQL server aggregates
and caches those APIs to serve
multiple apps leveraging the
platform.

30.
Section
Results
The platform reached a year of service recently
and we are continuing to build new apps and
services on it.

Backstory - how did we get
involved?

34.
How did we get started?
AWS Serverless Meetup at Myplanet
We started our journey when
Myplanet hosted a Serverless Meetup
session by Alex Coqueiro from AWS on
DeepRacer. (Thanks Shanly!)
We launched a DeepRacer channel
after that for collaborative learning.

35.
Toronto Summit League
AWS Toronto Summit
Winning AWS Toronto Summit has
given us a chance at reInvent 2019
Championship.
We won the #1 and #4 spots and
got an entry to reInvent 2019
Championship!

and reInvent

Team Work
Team work
1. Innovate and make mistakes
a. Mistakes bring up new ideas
b. Try anything - get new
ideas!
2. Learn
a. Always ask feedback and
second opinions
b. Analyze using log analysis
3. Iterate
a. You never know which one is
your winning model

38.
Track Building DIY
Track building DIY
- Cheaper than printing
- Reusable
- Easy to fold/deploy/customize
- You can add your own track

reInvent 2020
DeepRacer Evo and DeepRacer 2020
AWS just announced DeepRacer Evo - 2
cameras and a LIDAR sensor (for object
detection and avoidance), 3 or 5-layer
CNN and more physical and virtual
summits, and you can do private
leagues! So start your engines!

Head to head racing
Race against another DeepRacer
that is on the same track. Do your
best to avoid it while still turning in
the best lap time.

Q&A
Anything we did not discuss you feel curious
about?

PRESENTED BY
The Best Path a
DeepRacer can Learn

55.
The Ideal Racing Line

56.
• Follow a straight line for as long as possible
• Use the full width of the track to make the widest
possible turn around a curve
• Keep braking to a minimum and get it all done before
you start turning
• Accelerate throughout the curve and exit it at full
throttle
How do we race it?

57.
• Smooth paths can be raced faster
• List of waypoints (x, y)
• If the waypoints were a data stream, how might we
smooth them out?
• In signal processing, we often smooth out (filter) data
streams
• Low-Pass RC filter?
• Simple digital implementation
Smoothing-out the track

58.
Low-Pass RC Filter

59.
How do we refine it?
• Filtering is a good start, but we need to refine
• Do NOT edit your path in the waypoint space,
edit in the direction space!
• Start with constant directions for straight
tracks
• Start with linear direction changes for curves
