This article will provide readers with an in-depth understanding of “What is Cloud Native Architecture?” as well as the subjects that revolve around the solution.

During the pandemic, companies had to make some major changes. Organizations had to adapt to the “Work-From-Home” culture to sustain. 

Businesses began discovering new options and solutions for a cloud-based environment. This gave a rise to the companies using open source and commercial tools for their business.

One such solution that helped companies sustain is Cloud Native Architecture. 

What is Cloud-Native Architecture?

Explaining Cloud-Native Architecture

Cloud-Native Architecture is the design or plan made for applications and solutions. It is developed for applications and solutions to work in the cloud.

It is a design methodology to build applications as microservices. The microservices are run on the containerized and dynamic orchestration platforms.

Microservices are an important aspect is that makes it robust. Microservices streamlines and executes tasks in small portions for an application.

What are the types of Cloud Native Architecture Designs?

  • Basic: The Basic Cloud-Native Architecture Design is what regularly backs up the system on the cloud. It is easily accessible using DNS.
    The DNS accesses a load balancer and connects the user with the application. It stores key data in the master and slave database to communicate with the application.
  • Multi-Cloud: The Multi-Cloud Native Architecture Designs is what runs on multiple cloud platforms. It is accessible using DNS.
    And does not require a duplicate system to be set up. It helps store data on the platforms and allows the components to work in various environments.
  • Hybrid: A Hybrid Cloud Native Architecture is what makes it easier to connect load balancers to the applications. It allows users to access the app using DNS. The app is pushed to a master database. It stores the duplicates in the slave database, another cloud platform, or in the infrastructure.

The Key Principles of Cloud Native Architecture

To completely understand cloud-native architecture, it is important to know “What are its Key Principles?”. It runs on these key principles and it is crucial to know “What is it?” and “How to master?”

Following certain principles ensure optimized performance and faster delivery. The design and execution of an effective application depend on these principles. 

Self-Reliant Container

A cloud-native architecture includes containers. The containers include important requirements for a specific microservice.

It includes requirements like libraries, dependencies, and a light runtime. The requirements are packaged in an isolated container. It allows developers to easily migrate them from one environment to the other.

Mobility and independence are what make this principle unique. It provides an externalized configuration.

The container has a fixed infrastructure. It is configured for a specific environment.

Managed Services Designed for Interaction and Collaboration

A Cloud-Native Architecture requires effective communication to run its services. It needs to communicate within the infrastructure and with third-party applications. 

Uses APIs which is what helps it build communication between services and external applications. Manages internal communication using microservices.

With microservices, an architecture requires an additional layer. It is dedicated to the infrastructure and it is what creates effective communication. 

The additional layer is a service mesh. Its most important role is to connect, secure and monitor services.

Stateless and Scalable Components

A cloud-native architecture needs applications that are state-independent. It enables storing the state externally and allows instances within a service to process according to requests.

A distributed component is what guarantees as many stateless components as possible. It enables the system to scale, repair, and load balance avoiding maintenance of data persistence or sessions.

It can scale horizontally to add and remove instances when required. The activity depends on the workload.

The stateless feature is what allows developers to fix instances and avoid heavy downtime. It also allows easy techniques to roll back to the previous version of an application and load balance between instances.

Automated Processes and CI/CD Pipeline

A system helps infrastructures to automate easily. It allows developers to easily automate infrastructures using CI/CD pipelines.

The CI/CD pipelines enable faster repairs, scaling, and deployment of applications. Hence the building, testing, and deploying processes of an application must be automated. 

Processes like rollbacks, canary deployments, scaling, monitoring, and recovery can be easily automated. This helps in delivering quicker solutions and repairs for applications.

Robust Architecture

When developing the app, the major focus is to create an application that is robust. The application built and configured should provide high availability and an efficient disaster plan.

Errors are sometimes unpredictable and unavoidable. An effective way to deal with them is to plan for potential threats that may occur.

Microservices are what establishes a robust and resilient system. Features like automated recovery and stateless scalable components also allow instances to handle tasks if required. 

Hence, it minimizes downtime and the application is running without interruptions. This leads to a great user experience.

What you should know about Microservices?

Microservices are at the core of architecture. They are small autonomous programs with individual data storage and application logic.

Microservices execute business functions. 

Understand the works of a Microservices Architecture:

As discovered microservices are the important aspects of the architecture. It is critical to understand the components in a Microservices Architecture.

  • API Gateway: API Gateways are the first phase for the clients that they need to call. It works as an entry point and forwards the clients’ calls to the classified back-end services.
    It gathers the responses from multiple services and returns the same to the client.
  • Microservices: Microservices in the architecture are assigned to different functions called small services. These services execute certain tasks specific to their functionalities. 
  •  Database: Microservices either share a centralized database and can also have independent or isolated databases.
  • Inter-Microservices Communication: Microservices represent various functionalities in architecture and require strong and smooth communication. Hence it utilizes protocols like REST or messaging for effective interaction.

What is meant by a Cloud-Native Application?

To further understand Cloud-Native Architecture it is important to know about its Applications. Cloud-native applications use a different approach than traditional applications. 

Traditional apps are developed and deployed as a complete solution. Cloud-Native Applications are built on microservices that are self-contained and deployed independently.

Cloud-native applications are built using cloud-native architecture. These apps enable companies to introduce new ideas in the market and deal with customers better.

It works for public and private clouds, which is what makes cloud-native applications dependable. It allows DevOps to continuously deliver solutions using microservices and containers.

Why is Cloud-Native Architecture Important?

  • Developing software solutions on the cloud is cost-effective. Saves the costs and efforts of developing an on-premise IT environment. 
  • It deploys and automates applications for faster development. It conserves time, minimizes errors and bugs as well as improves delivery.
  • Applications developed on a cloud-native infrastructure are what make a project scalable. In case of new developments and requirements, teams do not need to wait for approvals and can easily make necessary changes.
  • Cloud services enable developers to utilize auto-scaling and gather required resources. It allows developers to use the resources optimally and provide efficient results.
  • Cloud-Native Architecture allows for faster development of applications. It also enables developers to automate repetitive tasks to save time and effort.
