Cloud-native refers to the concept of building applications and executing them in a dynamic containerized cloud-based architecture. Cloud-native broadens the scope for building scalable applications, as the possibilities for developing and testing an application are in a more dynamic environment. Developers working on building a new product have access to the public, private and hybrid clouds, which can be integrated with containers, service meshes, microservices, APIs, and more.
There is a continuous need to upgrade and deliver software that is sustainable and meets more than expectations. With this cutting-edge technology rivalry, it becomes imperative to be a smart decision-maker. Cloud-native thus claims to meet the demands with a wide range of private, public, and hybrid environments available today, with its robust and scalable architecture.
Brief Note: The Cloud Native Computing Foundation (CNCF) is an entity that hosts a range of critical components of the global technology infrastructure. It facilitates the assimilation of developers, end-users, and vendors, and runs the largest network of open-source developer conferences.
Cloud-native applications are a great way for organizations to overcome infrastructural limitations and can keep pace with advancements in technology. In the age of DevOps processes, with a continuous delivery model, the cloud-native environment serves the right purpose by providing a customized set of services, so that organizations efficiently meet the goals.
Cloud-native environment abstracts the underlying computing capabilities, storage, network, and other components required to run any software.
The traditional methodology for building and testing applications in a monolithic framework relied closely on the components needed to run it, that is, the architecture was tightly coupled. The application was developed as a single unit, which required all components in one place, that is database, network, business logic, and so on. Therefore, it required a composite infrastructure to execute any application. All was fine until a small change was made in a module and the whole application had to be tested, which was cumbersome, as well as, an unnecessary task. As far as scalability is concerned, monolithic architecture takes a backseat.
The limitations of monolithic architecture are addressed by microservices architecture, which offers greater scalability and has loosely coupled services. These are small services that run independently of each other and have greater ease of building and testing individual modules. Once tested, the changes are automatically integrated with the main application without affecting other untouched modules.
Cloud-native computing has eliminated barriers that existed with legacy systems. Cloud has offered the ease of building and deploying irrespective of geographical or infrastructural boundaries. Cloud-native thus leverages the concept of containerization and microservices with an intent to carry on continuous integration and deployment efforts to meet the DevOps culture requirements. Thus, with cloud-native, we are moving towards faster and efficient releases in small but successful cycles.
