What is a Cloud Native Stack? Exploring the Definition and Components

The IT industry has dramatically evolved in the last decade, and a significant contributor to this evolution is the concept of the cloud native stack. A recent survey conducted by the Cloud Native Computing Foundation (CNCF) in 2020 states that approximately 92% of organizations have adopted cloud-native technologies.

The adoption of cloud-native technology allows companies to leverage scalable, resilient, and highly available infrastructure, as well as improve maintainability and automation capabilities critical for modern applications. This article will provide insights into the definition of the cloud native stack, how it works, benefits, use cases, best practices, and recommended books to deepen your understanding.

“Cloud native stack is the backbone of modern software infrastructure, enabling organizations to quickly scale and adapt to the ever-evolving digital landscape.” – Satya Nadella, CEO of Microsoft

What is a cloud native stack? Definition of Cloud-native Solution Stack

A cloud native stack refers to a collection of complementary technologies that together enable the design, development, deployment, and management of applications in flexible, scalable, and highly available environments. These technologies leverage the cloud’s inherent capabilities, such as automated scaling, flexible storage options, and distributed computing, to build and run applications in a modern, efficient, and easy-to-manage manner.

ℹ️ Synonyms: Cloud-native architecture, cloud-native platform, cloud-native infrastructure, cloud-native technology.

How it Works

The cloud native stack comprises several components, which together facilitate rapid application development and deployment across various platforms. Here is a brief overview of the fundamental components of a typical cloud native stack:

Microservices architecture

This architectural style involves breaking applications into small, independent, and loosely coupled services. Each microservice is responsible for a specific functionality and communicates with other microservices via APIs.

Containerization

This approach involves packaging applications and their dependencies into lightweight, portable containers, making applications easier to deploy and manage by abstracting the underlying infrastructure. Popular containerization platforms include Docker and containerd.

Orchestration

Orchestration is crucial for managing containers and microservices in dynamic environments. Orchestration platforms such as Kubernetes and Docker Swarm handle tasks like load balancing, auto-scaling, rolling updates, and fault tolerance.

Continuous Integration and Continuous Deployment (CI/CD)

CI/CD pipelines are essential for automating application development, testing, and deployment processes, promoting faster updates and higher quality standards. Popular CI/CD tools include Jenkins, GitLab, and CircleCI.

Benefits of Using Cloud Native Stack

Opting for a cloud native stack offers numerous advantages, including:

• Scalability: Automatically scale resources based on application requirements, ensuring optimal performance without over-provisioning.
• Resilience: Easily handle failures, reducing downtime and maintaining application availability.
• Flexibility: Develop and deploy applications using a variety of languages, frameworks, and platforms.
• Cost-effectiveness: Pay for only the resources you use, and eliminate the need for costly hardware and infrastructure maintenance.
• Increased Speed of Innovation: Accelerate application development and release cycles, improving time-to-market and staying ahead of the competition.

Cloud Native Stack Use Cases

Organizations across various industries have embraced cloud native stacks to help them address the challenges of modern application development and management. Here are some use cases:

Financial Services

Banks and fintech companies use cloud native stacks to implement microservices, enabling them to develop and deploy services such as payment processing, fraud detection, and loan management more quickly.

Healthcare

Healthcare providers are adopting cloud native stacks to create telehealth solutions that provide remote access to medical records and consultation, improving patient outcomes and reducing costs.

Retail

Retail businesses leverage cloud native technologies to develop and deploy scalable e-commerce platforms, capable of handling increased traffic during peak shopping periods.

Media and Entertainment

Media and entertainment companies use cloud native stacks to build and deploy content delivery platforms, video streaming services, and recommendation engines, enhancing the user experience.

Code Examples

import express from 'express';
import { createConnection } from 'typeorm';
import { UsersRouter } from './routes/UsersRouter';

// Create a new express app instance
const app: express.Application = express();
// Set up body-parser middleware to parse JSON input from request body
app.use(express.json());

// Connect to the database using TypeORM
createConnection()
  .then((_connection) => {
    console.log('Connected to the database.');

    // Set up a route for managing users
    app.use('/users', UsersRouter);

    // Start the express server
    app.listen(3000, function () {
      console.log('App is listening on port 3000!');
    });
  })
  .catch((error) => {
    console.log('Error connecting to the database:', error);
  });

Best Practices

Successfully adopting a cloud native stack requires adherence to specific best practices, including designing applications with microservices architecture, implementing DevOps processes, establishing well-defined CI/CD pipelines, containerizing applications, and choosing the appropriate orchestration platform, among others. It is crucial to focus on security, monitoring, and compliance by incorporating standards and observability tools throughout the application lifecycle. Ultimately, organizations must constantly explore and adopt new technologies to stay competitive and reap the full benefits of the cloud native stack.
