Now, without beating around the bush, let’s quickly dig into the topic and start a discussion on Cloud Native.
What is Cloud Native?
The concept of creating and executing applications to make use of the computing capabilities is known as Cloud Native. It is provided by the cloud delivery model.
Cloud Native was created to take advantage of the size, elasticity, resilience, and flexibility.
Companies like Netflix, which used cloud technologies to transform from a mail order business to one of the biggest client on-demand video delivery networks, are credited with coining the term “Cloud Native” 10 years ago.
Netflix was the first to use what is now known as Cloud Native, rethinking, reshaping, and scaling how we all want to be developing software.
Now that you know what Cloud Native is, it’s time to understand why companiesuse it.
Why is Cloud Native used?
Cloud Native is used exponentially by companies for a variety of reasons, we have mentioned a few of them for you:
- Draw in and keep excellent talent
Developers enjoy working with Cloud Native and other cutting-edge open source software because it enables them to move more quickly and invest less time in infrastructure.
Hiring superior developers result in better products, which boost innovation for your business. Contributions to open source can also help you build a reputation as a leader in the technology industry.
DevOps automation capabilities are used by Cloud Native apps to enable continuous delivery and deployment of software updates that are delivered on a regular basis.
Additionally, developers can make changes to the apps without affecting the user experience by using approaches like blue-green and canary deployments.
Their architecture enables the autonomous development of Cloud Native applications. This implies that you can manage and use them separately.
Sounds fascinating? Let us take you even deeper to explore Cloud Native Architecture:
Cloud Native Architecture
An application that has been created expressly for cloud deployment is said to have a Cloud Native architecture. In other terms, a Cloud Native architecture is an application design pattern created from the ground up for a cloud environment.
Cloud Native architecture is made specifically to take full use of the cloud computing concept. It combines DevOps techniques, cloud computing approaches, and software development ideas.
Networking, servers, data centers, operating systems, and firewalls are all abstracted from all IT layers. It enables businesses to create applications as loosely connected services using a microservices architecture, and then execute those services on platforms with dynamic orchestration.
The Cloud Native application architecture produces dependable, scalable, and fast-to-market applications.

Horizontal scalability, distributed processing, and automated component replacement are the main objectives of Cloud Native design in order to achieve resilience and scale. Let’s look at it.
The application is constructed to run well at scale and was developed with scalability in mind.
The application’s minimal, scalable components allow for simple horizontal scaling.
The application has a high level of failure resilience. When a component fails, it may be quickly and automatically replaced without affecting how the remaining components function.
The programwas created with security in mind, working on the premise that a hacker has already gained access to the network and shouldn’t be able to jeopardize the data or the application.
Cloud Native Applications
Cloud Native applications are those that are created and deployed utilizing cloud-based technology. The cloud hosts and oversees them. In the cloud, it is created, tested, deployed, and maintained. It is therefore carried out entirely in the cloud. These programs make use of the benefits of the cloud computing delivery system.
Let us have a look at the applications of Cloud Native:
- Infrastructure driven software
Virtualizing physical functions almost totally requires replacing switches, knobs, and connectors with software. This makes it simple to use software to automatically start and stop services, reallocate resources, and adjust upward and downward capacity.
Applications that are built for the cloud rely on an infrastructure that is flexible and able to meet their demands.
Compared to traditional virtual machines, containers provide both efficiency and speed (VMs). A single OS instance is dynamically split into one or more isolated containers using operating-system-level virtualization, each of which has its own writable file system and resource allotment.
Containers are the perfect computing vehicle for deploying individual microservices because of their cheap overhead for building and deleting them and their great packing density in a single VM.
The purpose of DevOps is to provide high-quality software that addresses consumer concerns by working together with IT operations. Software development, testing, and release occur more often and reliably in environments created by DevOps.
- Application Programs Interfaces (APIs)
Software connections known as APIs make the functionality accessible to other programs. They make it simple to modify or expand programs without changing the underlying code, which is often a bad practice to engage in. Developers may access extensive functionality in other programs by using APIs.

Benefits of Cloud Native
Applications created for the cloud will naturally function effectively in this setting, allowing you to take full use of everything it has to offer. We have mentioned a few advantages and benefits that you can take from Cloud Native below, have a glimpse:
- Simple management
Cloud Native offers a wide range of solutions to simplify infrastructure administration. About ten years ago, PaaS platforms like Heroku and App Engine were the beginning, and now serverless platforms like Azure Functions and AWS Lambda are part of the trend.
Through the use of functions that you upload as part of serverless computing platforms, you may avoid worrying about setting up networking, assigning enough storage, or establishing cloud instances. Serverless handles everything.
Cloud Native applications’ scalability and flexibility enable you to make changes in real-time to further optimize the performance of your apps. They also enable you to respond quickly and make the required modifications to meet your clients’ shifting demands.
- Improved security
Security is obviously a key concern given Cloud Native’s powerful architecture and the communications inside the decentralized framework. Various services and the organization and the user are continually exchanging data. This results in a number of gateways that may serve as possible entry points for hackers into a Cloud Native system.
It is essential to make sure that each unit is only exposed to pertinent data and fields and to audit data access. Beyond the security precautions offered by the Cloud Native infrastructure vendor, the organization can adopt additional security steps such as multi-factor authentication, limited access, and sharing to ensure several levels of protection.
- Making troubleshooting simpler
As microservices are present, Cloud Native apps have an inbuilt fault tolerance mechanism. Because the entire program is broken up into microservices, each of which performs a different service function, Cloud Native infrastructure makes it much simpler to trace the source of problems during debugging after deployment. Once the service has been tracked, the issue is identified and repaired at the source without any server downtime.

Future of Cloud Native
For quite some time, it has been a popular topic in software development. Some coders write it off as a fad that will pass eventually. Some believe it to be the direction of software development.
Whatever it provides, Cloud Native will be a major trend in the next few years. Additionally, it has altered the way we create, use, and maintain software.
By putting a focus on Cloud Native, software development teams will be given the ability to launch and scale programs at a rate that wasn’t feasible before the advent of cloud solutions. These applications are created to meet business needs, test new features, and experiment without endangering client operations.
Cloud-native applications have become increasingly popular in recent years and are expected to dominate software development in the future. According to a survey, there will be at least 8.5 million cloud-native developers in 2030. Therefore, if you want to learn this technology, now is the time to do it.
