In the world of software development, cloud-native has been a hot topic for quite some time now. There are developers that believe that it is nothing more than a hype that is set to lose traction in the near future, but for most, it is not only one of the biggest and strongest trends in the industry but the future of IT. There is no denying that cloud-native has changed the way we look at operating, deploying, and developing software products. In this article, we will take a look at some of the features of cloud-native to see why it is one of the keys to the transformation of the IT industry.
What is Cloud-Native?
We all know businesses can sign up with a cloud service provider and use it to power their existing applications. But cloud-native is much more than that. It plays a huge role in the operations, deployment, implementation, and design of applications. It is an approach to building and running applications in a way that they are able to extract the maximum amount of advantages that the cloud computing model has to offer.

Features of Cloud-Native
Cloud-native apps are designed to be scalable, highly available, and fault-tolerant. They are typically built using microservices architectures and delivered as a service using DevOps practices.
Common features of cloud-native apps include:
Elasticity
The ability to scale up or down quickly in response to changes in demand. This is achieved by running the app in a containerized environment such as Docker, which can be easily deployed across multiple servers.
High Availability
The app must be able to continue running even if individual components fail. This is achieved by running the app in a distributed system with multiple instances of each microservice.
Fault Tolerance
The app must be able to continue running even if an entire server fails. This is achieved by replicating data across multiple servers and using load balancing to route traffic to the working instances.

DevOps
A set of practices that enables rapid delivery of cloud-native apps. This includes automating the build, test, and deployment process, as well as using continuous integration and continuous delivery (CI/CD) tools.
Containers
Containers are a form of virtualization that allows you to isolate an application or process from the rest of the operating system. This enables you to run multiple applications on the same server without them interfering with each other. Containers also make it easy to package and deploy applications, making them ideal for use in cloud environments.
Orchestration
Orchestration is the process of automating the deployment and management of containerized applications. This includes tasks such as provisioning resources, configuring networking, and monitoring applications. Orchestration tools can help you manage large numbers of containers and ensure that your applications are running smoothly.
Microservices
Microservices are a type of architecture that breaks an application into smaller, independent components. This makes it easier to develop and deploy applications and also allows you to scale individual components as needed. Microservices are often used in conjunction with containers and orchestration tools.
