What is Cloud Native Application?

A cloud-native application is a software application designed to operate in a cloud computing environment. This approach involves breaking down the application into smaller, more manageable components built and deployed as independent microservices.

The architecture of a cloud-native application is designed to take full advantage of the dynamic resource allocation capabilities of the cloud. The application can automatically scale up or down based on demand without manual intervention. Additionally, cloud-native applications are highly resilient and can automatically recover from failures and also, maintain service as per availability.

Cloud-native applications are built, using the fundamentals of DevOps practices, which automate development, testing, and deployment processes. This approach provides faster and more reliable application delivery along with greater collaboration between the development and operations teams.

Characteristics of a Cloud Native Application

Cloud-native applications are software applications that are designed, developed, and deployed with a set of cloud computing principles. 

Some of the key characteristics of cloud-native applications are discussed below points:

• Containerization- Cloud-native apps utilize containers, which are self-contained bundles of code, libraries, and dependencies, enabling rapid deployment and scaling across diverse environments.
• Microservices Architecture- Cloud-native apps embrace microservices, breaking them into modular components for independent development, testing, and deployment, fostering flexibility, scalability, and resilience.
• DevOps Automation- Developers adopt DevOps automation for streamlined development, testing, and deployment processes, enabling faster and more reliable collaboration between development and operations teams.
• API Integration- APIs facilitate seamless data and function exchange among microservices, empowering the creation of agile, modular components that can be easily integrated and scaled.
• Infrastructure as Code (IaC)- IaC automates infrastructure management through code, simplifying deployment, configuration, and version control while enhancing efficiency, reducing errors, and promoting collaboration.
• Cloud-Native Technologies- Cloud-native apps are designed for cloud-native infrastructure, like Kubernetes or various cloud platforms, harnessing the scalability, flexibility, and agility of cloud computing.

Cloud Native Tools

Cloud-native tools mostly refer to a set of software tools and technologies that are developed to run and manage applications in a cloud-native environment. These technologies make it easier for developers to design scalable and resilient apps by streamlining the process of deploying and managing cloud-native applications.

The following are some well-known cloud-native tools:

• Kubernetes- Automating the deployment, scaling, and maintenance of containerized applications is Kubernetes, an open-source platform for container orchestration.
• Docker- Developing and running distributed programs in containers is made possible by the open-source platform Docker.
• Prometheus- It is a free toolset for monitoring and alerting that facilitates the gathering and visualization of information from many systems.
• Istio- It is a platform for managing and securing service mesh-based applications that are open-source.
• Helm- Applications can be managed, installed, and upgraded with the help of Helm, a package manager for Kubernetes.
• Envoy- It is a free and open-source edge and service proxy that facilitates the management and security of traffic between microservices.

Advantages of Cloud Native Applications

Cloud-native applications have become popular due to several advantages. Understanding these advantages can help organizations make informed decisions when adopting this technology.

Below are a few of the advantages of cloud-native applications:

• Scalability- Cloud-native applications are designed to be highly scalable and can easily handle fluctuations in traffic and user demand. The use of microservices and containerization allows for horizontal scaling, where additional instances of a service can be added or removed to match demand.
• Agility- These applications can be developed, deployed, and updated quickly and efficiently. The use of DevOps practices and automation tools allows for rapid iteration and deployment of new features.
• Resilience- These are designed to be resilient and fault-tolerant. The use of container orchestration and distributed data stores ensures that the application can continue to function even if some components fail.
• Cost-effective- It can be cost-effective as it can be deployed on a pay-as-you-go basis, where you only pay for the resources you use. The use of serverless computing can further reduce costs by eliminating the need to manage and provision servers.
• Platform independence- Cloud-native applications can be deployed on any cloud platform or on-premises infrastructure, making them highly portable and flexible.

Disadvantages of Cloud Native Applications

Despite the many benefits of cloud-native applications, there are also some disadvantages to consider. It is important to assess these factors carefully when deciding to adopt a cloud-native approach.

The disadvantages of cloud-native applications are:

• Complexity- Cloud-native applications can be complex to design, develop, deploy, and manage. The use of microservices, containers, and orchestration requires a steep learning curve and can be challenging to implement.
• Security- Cloud-native applications can be vulnerable to security threats due to their distributed and decentralized nature. Additional security measures, such as encryption and network segmentation, may be required to ensure data protection.
• Cost- While cloud-native applications can be cost-effective, they can also be expensive to develop and maintain. The use of specialized tools and expertise required to build and manage cloud-native applications can be costly.
• Infrastructure dependency- Cloud-native applications are dependent on the underlying cloud infrastructure, which can be subject to outages, downtime, or compatibility issues. The need for constant monitoring and maintenance of the infrastructure can be a challenge.
• Vendor lock-in- Cloud-native applications can be tied to a specific cloud provider or technology stack, which can limit flexibility and portability. The use of open-source tools and standards can mitigate this risk to some extent.

Examples of Cloud Native Applications 

Below we will highlight some of the popular examples of cloud-native applications that utilize the power of cloud technologies.

• Netflix:
  Netflix is an excellent example of a cloud-native application. It has transitioned from a traditional DVD rental service to a leading global video streaming platform. Netflix relies heavily on cloud technologies, using microservices architecture, containerization with Docker, and container orchestration with Kubernetes. These cloud-native principles allow them to scale their infrastructure dynamically, deploy updates seamlessly, and provide a smooth streaming experience to millions of users worldwide.
• Airbnb:
  Airbnb, the popular online marketplace for lodging and hospitality services, is built as a cloud-native application. It utilizes cloud services like Amazon Web Services (AWS) to handle its website and mobile app infrastructure. By adopting a cloud-native approach, Airbnb can scale its platform elastically, manage user reservations and payments, and handle geographically distributed data efficiently.
• Spotify:
  Spotify, the popular music streaming platform, is another real-world example of a cloud-native application. Spotify utilizes cloud services and container orchestration to handle the vast music catalog, deliver personalized recommendations, and support millions of concurrent users across various devices. By taking advantage of cloud-native technologies, Spotify can scale its services on-demand, optimize resource allocation, and continuously deliver new features and updates.
• Pinterest:
  Pinterest, the visual discovery and bookmarking platform, is built as a cloud-native application. It leverages cloud infrastructure to store and serve millions of images, handle user interactions, and provide personalized recommendations. With a microservices architecture and containerization, Pinterest can scale its services based on user demand, improve performance, and continuously deploy new features and updates.
