The cloud is being used more and more. Paradoxically, it is also a source of misunderstanding. The Cloud covers a wide range of universes and technologies. One of the most frequently used is "cloud-native". But what does it actually mean?
Appearances are deceptive. At first glance, "cloud native" could mean that an application is deployed and runs in the cloud. In reality, it refers to the way applications are designed, deployed and managed.
The idea is to exploit the advantages of the cloud computing model. The aim is to increase the speed, flexibility and quality of application development, while reducing risk.
A cloud-native application is also easier to migrate to the cloud. It has already been designed with multi-tenancy, scalability, ease of integration and cloud management in mind. Conversely, migrating a non-cloud-native application to the cloud requires refactoring.
Cloud Native concept
The cloud-native concept is essentially characterized by the following four points:
Service-based architecture, including microservices. With a cloud-native approach, developers focus on creating specialized, single-function services, called microservices. Together, these small individual units make up a complete application, but each can be deployed, upgraded and managed independently.
API-based communication reduces complexity, scalability and maintenance efforts
Container-based infrastructure. Containerization is often used to make microservices easy to manage. Unlike standard virtual machines, which require an integrated operating system, containers are designed to run anywhere and are not dependent on a specific cloud platform or cloud service.
DevOps, a software development method that emphasizes communication, integration and collaboration between IT professionals to enable rapid product deployment.
By breaking down application code into microservices, developers can rapidly deploy updates to any part of the application. The cloud-native approach enables continuous delivery and greater flexibility.
