The emergence of microservices made us rethink how we built business applications. It led us to the migration of complex monolith applications to countless microservices. The cloud adoption and the suitability of the container services helped to revolutionize microservices.
Amidst this adoration for microservices came serverless, the next evolution of the cloud. Serverless brought deeper granularity with its technology offering. It tested our thinking, shifted our minds, and questioned us the way we’ve been building microservices. The agility of event-driven computing and the granularity of serverless allows us to break traditional microservices into multiple pieces.
In this talk, we will see how cloud and serverless help us build those pieces in isolation to achieve acceleration in our modern application development process.

Cloud evolution
12. Serverless requires a mind-shift to see the products as
event-driven orchestration of managed services, knitted
with infrastructure code, to bring the best value.

Mindset shift from a traditional monolith mountain thinking
to a molehill microservices thinking
17. A scene or sequence of scenes
whose execution requires
logistical planning
A realistic piece of stage scenery
built to stand independently as
part of a stage set
18. A rehearsed team manoeuvre
practised in training in
advance of matches
Parts of a model that are
built separately and
assembled together
19. Developing as Set-Pieces requires planning and
execution, but can be practiced in advance,
completed independently, and brought together.
20. Characteristics of a Set-Piece
1. Focus is on a Set-Piece
2. Planning is essential
3. Preparation/Practice takes to the main stage
4. Set-Pieces can progress in parallel
5. All the pieces together make the whole
23. Serverless computing enables to build event-driven
systems faster, because it speeds the feedback-
cycle so that the system iterates more efficiently.
Dave Anderson, Liberty Mutual
Agile, iterative and automated serverless
development is like a gravity defying take-off.
Once launched, no stopping!

25. Vision and Focus
Visualise big. Focus small
I just don’t think it’s that simple. Nothing is.
Everything is, when you break it down!

37. How to #1 – Focus on the parts
1. Logically group the functionality, subdomains
2. Identify unrelated features
3. Look for sync vs async features
4. Separate batch jobs
5. Don’t size-up and constrained by theories & textbooks
38. How to #2 – Plan the work well
Cloud provider

39. How to #2 – Plan the work well
1. Be humble. Start with the simplest pieces
2. Identify the immediate needs
3. Choose the tools that suit your need
4. Start with MVP thinking
5. Identify & define boundaries of each part
40. How to #3 – Practice (Test) the parts
Production

Develop
• Account name – different
• Cloud provider - same
• Services & resources – same
• Security options - same

61. Serverless requires a new way of thinking, new way of
working, and new way of running applications.
Meaning, we need to change our way of thinking, our way of
working, and our way of running applications.
