What is a private cloud? Which private cloud is better?

private clouds

refers to a cloud that can be used by bai alone and built by du, which provides the most effective control of data security and zhi service quality. Private clouds can be deployed in the firewall of enterprise data center, or they can be deployed in a secure hosting place. The core of private clouds refers to a kind of exclusive resources of enterprises.

public clouds

refers to the cloud that can store data provided by third-party providers. Generally, public clouds can be used through Internet connection, but the investment in construction cost is relatively low. Public clouds can be regarded as a resource service that can be enjoyed.

The new generation private cloud is not a new version of private cloud. On the contrary, it defines the OTA(Over The Air) characteristics of hardware, software and hardware decoupling, software evolution and hardware upgrade by software, and realizes the versionless perpetual life cycle of private cloud through the core point of evolution, as well as the breakthrough of the capability boundary from IaaS to PaaS scenarios.

The new generation private cloud is based on the safe, stable and efficient distributed cloud operating system of the new generation data center. It separates the platform from the service through the integrated and scene-based design concept, and realizes the evolutionary ability and light operation and maintenance ability of the whole platform, helping enterprise users to realize a unified architecture from the 3-node cloud-ready hyper-convergence of the most basic unit to the ultra-large-scale cloud platform without an upper limit. It is based on the open source ecological technology stack, while maintaining a highly productive experience. Through business insensibility, data migration and uninterrupted service.

strictly speaking, the first generation private cloud can only be called virtualization+cloud management. Enterprise customers basically don't have a new generation of cloud applications. Most of them go to the cloud from virtualization management and cost reduction. Such projects limit the imagination of private clouds and make the private cloud market questioned.

the second generation of private cloud, enterprise users have a new generation of cloud applications, but they are not competitive compared with public cloud in terms of richness and application fragmentation. The business model is still in the software era dominated by licence, and due to the complex customer environment, there is a lot of customization, and the deployment and operation and maintenance are complicated, so it is impossible to achieve a smooth upgrade.

both the first and second generation private clouds belong to the era of traditional private clouds. The purpose of users migrating traditional applications to the cloud architecture is mostly to reduce costs and improve manageability. Although this is also part of the value of the cloud, the growth driving force of the cloud will come from new enterprise-level applications in the future. It is still difficult to learn cloud computing now. It is recommended to find a professional training institution to study, and you can go to the Zhihu workshop to have a look.
