Building Scalable and Resilient
Cloud-Native Applications

The software development landscape is constantly
evolving, driven by cutting-edge technologies, modern
architectural design patterns, and the demand for always-
on, secure, resilient, and adaptable computing.
Additionally, fundamental shifts in thinking occasionally
occur due to the emergence of breakthrough technologies
that significantly impact software development direction,
such as the development and adoption of cloud-native
architecture.

As a result, cloud-native applications are increasing in
popularity and are fast becoming a mainstay of our post-
modern, global economy. We have moved from the
monolithic age to the cloud age into the cloud-native age,
where applications are now purpose-built to leverage the
benefits of the cloud, including characteristics such as
exceptional agility, resiliency, scalability, and elasticity.
To further emphasize this point, it is worth considering the
2022 survey by Cloud Native Computing Foundation
headlines with:
“[2022:] The year cloud native became the new normal.”

Additionally, a November 2021 report by Gartner noted the
following:
Global cloud
revenue will
increase to
more than $474
billion in 2022,
an increase of
$66 billion from
the 2021 figure
of $408 billion.
More than
85% of
organizations
will move to
the cloud and
the cloud-
native model
by 2025.
Over 95% of all
new IT
workloads will
be rolled out
on cloud-
native
platforms by
2025, up from
30% in 2021.

“The pandemic and the surge in
digital services have made cloud
the centerpiece of new digital
experiences.”

CLOUD NATIVE: WHAT AND WHY?
The research paper titled “Cloud-Native Applications,” published by IEEE,
describes the generally accepted translation of the term cloud-native as
meaning nothing more than an application hosted on cloud servers and not on
on-premises computers.
However, this expression means so much more than that. Cloud-native is also a
design pattern providing the blueprint for architecting an application built
specifically for the cloud, not just uploading a monolithic on-premises software
application onto the cloud.

1. CLOUD-NATIVE APPLICATIONS OPERATE AT
A GLOBAL SCALE
Essentially driven by the remote working and lockdown trends of the
global pandemic, cloud-native applications must operate globally,
serving users and customers across different geographic regions.
In other words, this partially defines the true nature of globalization or
the increasing interconnected and interdependence of netizens geo-
located worldwide.

2. CLOUD-NATIVE APPLICATIONS MUST BE
HIGHLY SCALABLE
In Information Technology, the term “scalable” is defined as an
application’s continued ability to function optimally when increased in
size or volume to meet an increased workload. Moreover, the phrase
“highly scalable” translates into the application’s ability to handle this
workload without undue strain.
In the cloud-native context, applications must be highly scalable with
thousands of concurrent users.

For example, the following diagram describes when we need to
scale resources up and down.

3. INFRASTRUCTURE IS FLUID AND FAILURE
CONSTANT
Why?
The law of large numbers guarantees that, even when failure rates for
hardware or networks are low, something is always broken or is about
to break when you attempt to run an on-premises application on a
global scale.
This is why it is imperative for cloud-native applications to be designed
with the principle: “Infrastructure is fluid and failure constant” foremost
in the development team’s collective minds.

4. SECURITY MUST NOT BE AN AFTERTHOUGHT
In cloud-native application architecture, security must be
integral to the application and not added as an
afterthought or after the application has been completely
developed.
Cloud-native applications execute in dynamic and
distributed environments, often handling sensitive data and
critical workloads. Therefore, security is vital to protect this
data, prevent unauthorized access, and ensure the
application’s integrity and continued availability.

CONCLUSION
Based on these cloud-native
properties, it is reasonable to
conclude that cloud-native is a
design pattern that has the capacity
to provide developers with a
blueprint to build highly adaptable,
efficient, and resilient applications
that check all the boxes for modern
cloud-computing environments and
provide the flexibility needed to
address the ever-changing business
requirements.
