Cloud Native: what is it and what is it for?

A Cloud Native approach is to develop an application taking advantage of the various benefits offered by the Cloud.Find out everything you need to know about it.

According to the Cloud Native Computing Foundation (CNCF) , founded in 2015 by the Linux Foundation, Cloud Native technologies enable organizations to create and run scalable applications in modern and dynamic environments such as the public, private or private cloud. hybrid .

Examples of technologies include containers , the mesh service, microservices, immutable infrastructures, continuous integration or declarative APIs. Applications created with this approach are typically based on an infrastructure as an IaaS service or a platform as a PaaS service that will then be combined with the previously mentioned tools.

What is the Native Cloud for?

A Cloud Native approach has several advantages. First, it allows companies to transform their application ideas more quickly into products available on the market . It not only speeds up change, but also reduces risk.

In addition, Cloud Native technologies also enable increased scalability for applications . As companies attract new users to more regions and more devices, it is possible to maintain application responsiveness and keep costs down.

Another major benefit is that it usually allows businesses to spend less money on accommodation. Thus, it is possible to effectively reduce the loads .

What are the differences with on-site applications

Cloud Native applications require a very different architecture than traditional enterprise applications , which is why they have many differences with on-premises applications.

First, while on-premise applications designed to be run on corporate servers are usually written in traditional languages ​​(C / C ++, C # …), Native Cloud applications are written in web-centric languages like HTML, CSS, Java, JavaScript, .net, Go, Node.js, PHP, Python or Ruby.

Cloud Native apps also have the distinction of being always up-to-date and available . On the other hand, on-premise applications require updates during which they are unavailable, and are usually offered with a subscription model by the vendor.

In case of peak use, Cloud Native applications can take advantage of the elasticity offered by the cloud by using more resources. These can then be disabled when usage returns to normal. This is a flexibility that is not available on site.

A source-based application can also be run in a virtualized environment and share resources with other applications. In the event of a failure of one of the Cloud Provider Data Centers, the stack can be immediately transferred to another region. The risk of downtime is therefore greatly reduced compared to an on-site application.

With Cloud, Cloud Native application management is fully automated with automation and orchestration tools. In addition, Cloud Native applications have a modular design because many of their functions can be broken down into microservices. It is therefore possible to disable certain features or to deploy updates for specific modules rather than for the full application.
