Key Characteristics of Cloud Native Applications
Unlike traditional monolithic architectures, cloud-native applications are designed to be modular, resilient, and dynamically scalable. The Cloud Native Computing Foundation (CNCF) outlines several key building blocks that define cloud-native architecture.
Microservices
Microservices are independent, self-contained services that handle specific functions within an application. Each microservice can be developed, deployed, and scaled separately, enabling faster updates and improving fault tolerance. This modular approach ensures that changes to one microservice do not impact the rest of the application.
APIs (Application Programming Interfaces)
APIs enable seamless communication between microservices by providing a structured way for them to exchange data. In cloud-native applications, APIs facilitate loose coupling, ensuring that services can work together efficiently without direct dependencies.
Immutable Infrastructure
Immutable infrastructure follows the principle that servers and virtual machines (VMs) are never modified after deployment. Instead of making changes to an existing system, a new instance is created, and the application is moved to it. This approach improves consistency, security, and reliability by preventing unintended configuration drift.
Containers
Containers package microservices along with their dependencies, ensuring they run consistently across different environments. They improve application portability, efficiency, and speed, allowing developers to deploy services without worrying about infrastructure compatibility. Tools like Docker and Kubernetes manage containerized applications efficiently.
Service Mesh
A service mesh acts as an application layer that manages secure and reliable communication between microservices. It enables traffic control, security policies, and monitoring without requiring changes to the application code. This is particularly useful in complex, distributed cloud-native applications.
Orchestration
Orchestration is the process of automating deployment, scaling, and management of cloud-native applications. Tools like Kubernetes ensure that all components work together efficiently, maintaining high availability and continuous integration and delivery (CI/CD). Orchestration simplifies application scaling and resource allocation based on real-time demands.
Cloud-native architecture is designed to maximize scalability, resilience, and agility. By using microservices, APIs, containers, service mesh, and orchestration, organizations can build applications that automatically adapt to changing workloads while remaining highly available and efficient.

Cloud-native application development involves creating, building, and launching software that is perfectly tailored for cloud environments. This friendly approach emphasizes speed, scalability, and automation, making it easier for developers to swiftly respond to the ever-changing needs of users and businesses alike.
Continuous Integration (CI): Faster Code Integration
Continuous Integration (CI) is a development practice where code changes are frequently merged into a central repository. Automated tests run on each change to identify bugs early, ensuring code quality and accelerating development cycles. CI reduces integration issues, making software updates more seamless.
Continuous Delivery (CD): Smooth and Reliable Deployments
Continuous Delivery (CD) extends CI by automating application deployment into production-like environments. It ensures that microservices are always ready for deployment, allowing businesses to roll out new features and bug fixes with minimal downtime. CD, combined with CI, forms the foundation of efficient software delivery pipelines.
DevOps: Bridging Development and Operations
DevOps transcends methodology; it embodies a collaborative culture uniting development and IT operations teams. By automating workflows, improving monitoring, and enhancing security, DevOps helps organizations build and deploy applications more efficiently and reliably, reducing time-to-market.
Serverless Computing: Deploying Without Managing Infrastructure
Serverless computing enables developers to run applications without managing servers, as cloud providers dynamically handle infrastructure scaling. This model is highly cost-efficient and scalable, making it ideal for applications with variable workloads. Combined with microservices, serverless architectures enhance performance while reducing operational complexity.
Cloud-native application development is not just about coding in the cloud—it’s about using modern development strategies to build applications that are flexible, resilient, and scalable. Embracing CI/CD, DevOps, and serverless computing allows businesses to thrive in the exciting and constantly changing digital landscape.

Cloud Native Applications vs Traditional Enterprise Applications
When it comes to cloud native applications, it differs from traditional enterprise applications in many ways. Let’s take a look at how cloud native application gets the edge over the traditional approach:
Operating System Abstraction
Cloud native applications are developed in containers, making it possible for developers to build them regardless of the underlying operating system. Thus, developers can eliminate a lot of errors and save time.
However, this is not the same with traditional applications as it has to be built on an operating system, leading to many errors.
Consistent Timeline
Cloud native applications are mostly developed as microservices so it comes with a consistent and set timeline. Unlike traditional applications, cloud native applications require to be aligned with monolith architecture.
Automated Scalability
Another area where cloud native applications highly differ from traditional ones is the automated scalability factor. Cloud applications can quickly scale due to containers and microservices but traditional applications need shifting to a large infrastructure for scaling.
Appropriate Capacity
When it comes to cloud computing, developers only get the appropriate amount of resources for a specific process. However, enterprise applications include many unnecessary processes that often make it difficult for developers to manage.
Operation Cost
The operation cost of cloud native applications is quite minimal as resources can be managed according to the requirement. However, with enterprise applications you need to allocate large resources, leading to higher costs.
