The document discusses the challenges and benefits of developing native cloud applications (NCAs), emphasizing the need for applications to be designed specifically for cloud environments. It highlights the importance of redundancy, breaking tasks into separate services, and fostering a culture of automation and cross-functional collaboration. The document also outlines strategies for deployment and orchestration to enhance scalability and resilience in application design.

1. First steps in
Native Cloud Applications

2. Is your application ready to
scale out ?

3. Is this my
problem ? I think it should
be handled by
the infra guys
I will think
about that later.
Let’s focus on
my code.
Yes. The
sizing is well
cover for the
whole year

4. Resources
are Infinite
and Cheap
Infrastructure is
Immutable
Very
specialized
and Silo
Linear

5. Change is Hard
Change is Expensive
Change is Labor intensive

6. “Any organization that designs a
system (defined broadly) will
produce a design whose
structure is a copy of the
organization’s communication
structure”Melvyn Conway

"A Native Cloud Application (NCA) is a
program that is designed specifically
for a Cloud Computing Architecture."

12. "NCAs are designed to take advantage of cloud computing
frameworks, which are composed of loosely-coupled cloud
services. That means that developers must break down
tasks into a separate services that can run on several
servers in different locations. Because the infrastructure
that supports a Native Cloud App does not run locally,
NCAs must be planned with redundancy in mind so the
application can withstand equipment failure and be able to
remap IP addresses automatically should hardware fail."

18. 1.0

19. Orchestration
(Central brain to guide and
drive the process)
Choreography
(Inform each part of the
system of its job and let it
work out the details)

20. Deploy
independently of
the rest of the
system
Faster boot
(Elasticity also faster)
Isolation quickly
(in case of failure)
