5. Serverless is not just about the Tech:
5
Serverless is New Agile & Mindset
#1 Serverless Dev
(Back-end FaaS dev,
but turned into gluing
APIs and Managed
Services)
#2 We're obsessed by
creating business value
(meaningful MVPs,
Products), to empower
Business users
#3 We build bridges
between Serverless
Community (“Dev leg”),
and Front-end & Voice-
First developers & User
Experience designers
(“UX leg”)
#4 Achieve agility NOT
by “sprinting” faster
(like in Scrum), but
working smarter (by
using bigger building
blocks and less Ops)

6. Upcoming ServerlessToronto.org Meetups
6
1) Community Lightning Talks &
Updates for our 3rd Birthday
2) How to choose what Azure
services to use and when? –
Barry Luijbregts Azure MVP
& Pluralsight Author
3) This is my Architecture to
prevent $72K Cloud Bills /
bankruptcies – Sudeep
Chauhan, ToMilkieWay.com
4) ??? We need you ☺ Please rate us ☺

7. Why cloud-native Java topic & why now?
7
Java Developers: You’re more Cloud-native than you think ☺
Enterprises: Traditionally think of PCF (Pivotal Cloud Foundry) or OpenShift as
Platforms, but in reality, the underlying Cloud became an App Platform – especially
when using Managed Services & Serverless. Why care in COVID-times?
• Everybody is under pressure to cut costs – more now than before COVID
• Using “a platform on top of a platform” increases Project Complexity,
Development/Support/Cloud costs, plus decreases Speed to Market and
Innovation (as you’re limited to which Cloud Services are allowed to use),
• making IT more expensive, leading to more job losses, rate cuts… more “bleeding”.
Solution: Spring Boot App is the unit of portability, now
when most Clouds can run fully-managed Java Apps:
