What is Cloud Native Application

Defining Cloud Native Applications

Introduction to Cloud Native Concepts

Cloud native applications are engineered to exploit the scalable, flexible environment offered by cloud platforms. Unlike traditional applications that are often adapted for the cloud post-development, cloud native applications are inherently designed for cloud efficacy right from the start, thriving in dynamic, service-oriented architectures.

Microservices Architecture

What are Microservices?

Microservices architecture splits applications into smaller, independent units that perform specific business functions. This modular approach allows for independent deployment, scaling, and updating of different components, significantly improving agility and reducing risks during updates.

Benefits of Microservices in Cloud Native Applications

• Scalability: Each component can be scaled independently, making it easier to handle specific loads efficiently.
• Flexibility: Teams can develop, test, and deploy changes to individual services without impacting the whole application.
• Resilience: Faults in one service do not disrupt the entire application, enhancing overall uptime and reliability.

Containerization and Orchestration

Containers Explained

Containers package code and all its dependencies, so the application runs quickly and reliably from one computing environment to another. They are crucial for consistency across multiple development and release cycles, promoting DevOps practices.

Orchestration with Kubernetes

Kubernetes is a system for automating deployment, scaling, and management of containerised applications. It orchestrates computing, networking, and storage infrastructure on behalf of user workloads, managing the lifecycle of containers and ensuring they run where and when intended.

DevOps Integration

Continuous Integration and Delivery (CI/CD)

CI/CD pipelines automate steps in software delivery processes, such as building code, running tests, and deploying to production environments, enabling frequent feature releases and quick bug fixes with minimal manual intervention.

By understanding these core components and methodologies, IT professionals can better leverage cloud native applications to drive business innovation and efficiency. As organisations continue to evolve, the foundational principles of cloud native technologies enable a more resilient, scalable, and efficient IT infrastructure.

Microservices Architecture

Functionality and Design

Microservices architecture involves dividing a large application into smaller, independent services that communicate over well-defined APIs. These services are independently deployable, scalable, and maintain their own stack of technology, including database and data management models.

Advantages of Microservices

• Agility: Allows multiple teams to work in parallel on different services, speeding up the development process.
• Scalability: Each service can be scaled independently based on demand, without affecting the functioning of other services.
• Resilience: Failures in one service do not impact the availability of the entire application, ensuring greater overall stability.

Containers and Orchestration

Containerization

Containers provide a lightweight, consistent environment for applications to run in isolation from other applications, sharing the OS kernel but with separate execution environments.

Orchestration with Kubernetes

Kubernetes automates the deployment, scaling, and operations of application containers across clusters of hosts, providing support for container-centric infrastructure.

DevOps and Agile Methodology

Continuous Integration/Continuous Deployment (CI/CD)

CI/CD integrates regular code changes and testing, enabling automated deployment which helps in maintaining high-quality software through frequent updates and iterative feedback.
