What is cloud native?

Imagine a city that automatically builds new roads during rush hours, repairs itself after storms, and develops new neighborhoods as more people move in—all without disrupting daily life. This is what cloud-native applications bring to the software world.

Essentially, cloud native is a way of designing, building, and running applications that fully embrace the capabilities of cloud computing. It’s not just about hosting applications in the cloud, it’s about creating systems that:

• Expandable: Effortlessly handle millions of users
• elastic: Automatic fault recovery
• agile: Deploy updates quickly and frequently

Real-world examples of cloud-native applications in action

1. Netflix:

   • Netflix uses microservices and Kubernetes Handles over 200 million users worldwide
   • Each feature (e.g. recommendations, search, streaming) is a separate microservice
   • interesting facts: Netflix deploys code changes thousands of times a day with no downtime

2. Uber:

   • Uber’s ride-hailing app relies on Cloud native principles Instantly match millions of drivers and passengers
   • use container and Observability tools Ensure seamless performance

3. Spotify:

   • Spotify uses Kubernetes Manage its music streaming service
   • through adoption Cloud native architectureSpotify can deliver personalized playlists to millions of users

Why cloud native matters in 2025

transformed into Cloud native No longer just a trend; necessity For organizations that want to stay competitive in today’s fast-paced, digital-first world. This is why cloud native is critical:

1. Scalability: Easily cope with unpredictable traffic peaks

In a world where user needs can change in an instant (such as a viral social media post, a flash sale, or a global event), applications need to scale dynamically. Cloud-native architecture, powered by the following technologies container and Kubernetesallowing enterprises to automatically scale up or down their applications based on immediate needs.

• example: During Black Friday, e-commerce platforms can immediately add more resources to handle millions of shoppers and then scale back to save costs.
• why it’s important: Traditional systems often experience sudden traffic spikes, leading to crashes, lost revenue, and user frustration. Whatever the needs, cloud native ensures your applications are always ready.

2. Resilience: Minimize downtime through self-healing system

Failures are inevitable in any system, but cloud-native applications are designed to automatic recovery No manual intervention is required. by utilizing microservices and Container orchestrationcloud-native systems isolate failures and ensure the rest of the application continues to run.

• example: If a single microservice (e.g. payment gateway) fails, the rest of the application (e.g. product browsing, search) is not affected and the failed service is automatically restarted.
• why it’s important: Downtime can cost a business millions of dollars and damage its reputation. Cloud-native systems are elastic, ensuring high availability and a seamless user experience.

3. Speed: Deploy updates multiple times per day

In today’s competitive landscape, the ability to Rapid innovation Very critical. Embracing cloud native Development and operation practices like Continuous Integration/Continuous Delivery (CI/CD)enabling teams to deploy updates, bug fixes, and new features multiple times a day without downtime.

• example: Netflix deploys thousands of updates every day to ensure users always have the best experience, uninterrupted.
• why it’s important: Traditional development cycles can take weeks or months to release updates, leaving businesses behind competitors. Being cloud native enables organizations to respond instantly to market demands and user feedback.

4. Cost efficiency: optimize resource usage through pay-as-you-go model

Cloud-native applications are designed to take full advantage of cloud infrastructure, using resources only when and where they are needed. This is achieved by Auto scaling, Serverless computingand Containerizationthereby eliminating the need for over-provisioning.

• example: Startups can run their applications with minimal resources during off-peak hours and automatically scale during peak hours, paying only for the resources they use.
• why it’s important: Traditional systems often require businesses to make significant investments in infrastructure that sits idle most of the time. Cloud native ensures you only pay for what you use, reducing costs while maximizing efficiency.

bottom line

Cloud native is not just about adopting new technologies, it’s about embracing new technologies new way of thinking. It enables businesses to build applications such as Expandable, elastic, quicklyand High cost performanceensuring they can thrive in an unpredictable and ever-changing digital environment.

Pillars of Cloud Native (Simplified with Examples)

1. Container

• what are they: Containers are like application lunchboxes
• example: Developers use Docker to build web applications
• learning tools: docker

2. Kubernetes

• what is it: Kubernetes is like a flow controller for containers
• example: Automatically expand the online store server during sales
• learning tools: Kubernetes

3. Microservices

• what are they: Break the application into smaller independent services
• example：Amazon’s e-commerce platform service
• learning tools: spring launch

4.CI/CD (continuous integration/continuous delivery)

• what is it:Automated code integration and deployment
• example: Automated testing and deployment through GitHub
• learning tools: GitHub operations

5. Observability

• what is it: Monitor system health and performance
• example: Instant problem detection at Uber
• learning tools: Prometheus and Grafana

How to get started with cloud native (step-by-step roadmap)

Step 1: Learn the basics of cloud computing

• Learn about IaaS, PaaS and SaaS
• Explore the cloud platform
• resource: AWS Free Tier

Step 2: Main Container

Step 3: Learn more about Kubernetes

Step 4: Set up a CI/CD pipeline

Step 5: Implement Observability

Step 6: Work on the actual project

• Build cloud-native applications
• Deployed on public cloud
• resource: AWS EKS

Best practices for cloud-native development

1. Adopt a DevOps culture
2. Shift left safety
3. Use infrastructure as code
4. Focus on resilience
5. Stay up to date with the latest developments of CNCF
