What is Cloud Native Explained?
1.
2. What is Cloud Native
The term cloud native refers to the concept of building and running
applications to take advantage of the distributed computing offered by
the cloud delivery model. Cloud native apps are designed and built to
exploit the scale, elasticity, resiliency, and flexibility the cloud provides.
As defined by the Cloud Native Computing Foundation (CNCF), Cloud
native technologies empower organizations to build and run scalable
applications in public, private, and hybrid clouds. Features such as
containers, service meshes, microservices, immutable infrastructure,
and declarative application programming interfaces (APIs) best
illustrate this approach.
These features enable loosely coupled systems that are resilient,
manageable, and observable. They allow engineers to make high-
impact changes frequently and with minimal effort.
3. What is Cloud Native ?
Cloud native services empower modern
application development using technologies such
as Kubernetes, Docker, serverless functions, APIs, and
Kafka. Industry-leading cloud providers enable cloud
tooling and services so that developers can reduce
operational tasks and build applications faster. Cloud
native services give developers a comprehensive,
standards-based platform for building, deploying, and
managing cloud native applications such as
microservices and serverless functions.
4. What is Cloud Native ?
Cloud-native architecture and technologies are an
approach to designing, constructing, and operating
workloads that are built in the cloud and take full
advantage of the cloud computing model.
Cloud-native technologies empower organizations to
build and run scalable applications in modern, dynamic
environments such as public, private, and hybrid clouds.
Containers, service meshes, microservices, immutable
infrastructure, and declarative APIs exemplify this
approach.

6. Why to make the transition for cloud native Apps?
Does cloud native application development truly deliver apps that are
that much better than traditionally developed apps? Yes. The benefits to
cloud native apps are clear: cloud native apps can scale because their
functions are broken into microservices and they allow for individual
management. And since they are agnostic to their cloud infrastructure,
cloud native apps can run in a highly distributed manner, maintaining
independence and allocating resources based on the application needs.
Cloud native applications have become a key way to increase business
strategy and value, because they can provide a consistent experience
across private, public, and hybrid clouds. They allow your organization to
take full advantage of cloud computing by running responsive and
reliable cloud native apps that are scalable and reduce risk.
7. Cloud native components
Cloud native computing is a combination of several cloud native technologies. The key
players in cloud native are – Microservices, containers, Kubernetes, DevOps and CI/CD.
Besides these key players, cloud native takes advantage of several modern development
technologies and techniques such as PaaS, multi-cloud, agile methodologies, and
integration with other cloud offerings.
8. Benefits of Cloud Native Application
•Independence: Their architecture makes it possible to build cloud
native applications independently of each other. This means you also can
manage and deploy them individually.
•Resiliency: A well-designed cloud native application is able to survive
and stay online even in the event of an infrastructure outage.
•Standards-based: For interoperability and workload portability, cloud
native services are often based on open source and standards based
technology. This helps reduce vendor lock-in and results in increased
portability..
9. Benefits of Cloud Native Application
•Business agility: Cloud native applications enable flexible deployment
options across the network, and are also smaller than traditional apps,
which makes them easier to develop, deploy, and iterate.
•Automation: Cloud native applications use DevOps automations
features and enable continuous delivery and deployment of software
changes that get released on a regular basis. Additionally, developers
can use methodologies like blue-green and canary deployments to make
improvements to the apps without any disruption to the user experience.
•No downtime: Thanks to container orchestrators such as Kubernetes,
you can deploy a software update with essentially zero downtime.
10. What are cloud native services?
Cloud-native services are at the core of digital innovations and are key to
advanced analytics, mobile apps, and chatbots. DevOps practices
remove most of the management tasks associated with building,
operating, and maintaining a complex software platform. Software
development, deployment, and testing activities reside in the cloud and
can be expanded or contracted at will. Shifting applications, DevOps, and
workloads to a cloud native architecture is integral to keeping your
business competitive.
11. Disadvantages of Cloud Native
1. Cloud native architecture and cloud native application development
requires working knowledge of several new cloud technologies. Not only
cloud native development requires larger teams and there is a learning
curve, and the total cost of software development can be much higher.
2. Cloud native applications use cloud infrastructure and resources. In
cloud infrastructure, you pay as you go. If resources are not planned
properly, things can get costly very quickly. If you don’t pay attention to
unused or underutilized resources, your costs can be much higher than
you really need to pay.
3. Team needs to constantly upgrade themselves with the latest changes
in the cloud technology.
12. When should I choose Cloud Native Architecture?
Cloud native is a good fit when you have applications that that can scale independently, and traffic can
go up and down with major spikes. For example, Amazon website seems major traffic spike during
holidays.
Cloud native makes sense when an application is quite large and has frequent
updates and deployment. For example, Facebook deploys features 500 times a day
but in bits and pieces.
Cloud native make sense when an application is big enough and has modules and
each module can be built, tested, and deployed independent of other modules. Hence
microservices.
Cloud native makes sense for projects when multiple teams work on multiple
technologies and can be deployed services and functionality regardless of platform,
language, or target devices.
13. Summary
Cloud native is about speed and agility. Business systems are evolving
from enabling business capabilities to weapons of strategic
transformation that accelerate business velocity and growth. It's
imperative to get new ideas to market immediately.
These techniques enable loosely coupled systems that are resilient,
manageable, and observable. Combined with robust automation, they
allow engineers to make high-impact changes frequently and predictably.
Cloud native computing takes advantage of cloud capabilities to full extent. Cloud native
apps are developed and deployed in the cloud and runs in an automated fashion without
much involvement of IT. In this article, we learned about what cloud native is, what are
the advantages and disadvantages of cloud native architecture, and how to get started
with it.
