In this issue, the editor will bring you about how NetApp makes stateful applications easier to complete in Kubernetes. The article is rich in content and analyzes and describes it from a professional point of view. I hope you can get something after reading this article.

Introduction: NetApp has launched an enterprise-class data service for stateful cloud native applications that can be used with any Kubernetes distribution.

Most Web applications are stateless. These do not save client data from one session for the next session of one client.

A stateful application is an application that saves client data from one session to the next. Both methods have advantages. But running a stateful application in a container is not easy. NetApp hopes to fix this problem through the Kubernetes storage and container platform Project Astra.

In the early days of Kubernetes, it was commonly used to run Web-based stateless services. If stateful services, such as databases, are required, they must be run in a virtual machine (VM) or cloud-based service. Now, with the rise of Kubernetes-based hybrid clouds, users want to deploy stateful applications on top of Kubernetes orchestrated containers.

Project Astra is a software-defined storage (SDS) platform. It will provide a platform for stateful storage and data services for Kubernetes. In turn, this enables application and data portability for stateful applications.

Eric Han, vice president of product management for NetApp Cloud products CDS, explains: "many organizations realize that the associated data and data services (storage, management, protection, and replication of data) are not easy to use or portable by Kubernetes." Asta promises to "improve the data visibility of cloud native applications by automatically discovering applications and application data, classifying data and backups, reporting data usage, and so on."

This is important because, as Beth Busenhart, a strategist at NetAppmarket, says, "Kubernetes is becoming ubiquitous as the coordinator of container applications. It focuses on portability." Everything is fine, but it also means that "the container is stateless and the portability of the data is lost," Beth said.

There are ways to provide stateful services for Kubernetes. One of the most common approaches is to integrate the Kubernetes cluster with the traditional storage infrastructure and decouple the storage tier from the Kubernetes managed computing layer. However, this approach can neither be portable nor provide high I / O throughput.

Project Astra (still in beta) will allow developers to create portable, fast I / O Kubernetes stateful applications. These can be moved across multiple public and private clouds along with their data and data services. This makes the promise of being able to move programs across hybrid clouds easier to achieve. NetApp's vision for the Astra project is to enable the company to work seamlessly with Kubernetes distributions of choice on any cloud. Before that, NetApp realized that it was futile to have proprietary NetApp Kubernetes services (NKS) to compete with dozens of other Kubernetes vendors. Open source Astra has more hope of finding customers.

NetApp is working with the Kubernetes community to develop Astra. The goal is to build a platform to help you:

Use the Kubernetes discovery application of your choice, whether on your local or in the cloud.

Integrate and unify application and data management.

Provide NetApp expertise in data and Kubernetes through services and built-in capabilities.

Extends the commitment to portability of all workloads, including stateful, data-rich applications.

This is how the NetApp shared by the editor makes stateful applications easier to complete in Kubernetes. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
