What is a private cloud and what are its characteristics?

The new generation private cloud is not a new version of private cloud. On the contrary, it realizes the version-free, sustainable life cycle of private cloud and the breakthrough of capability boundary from IaaS to PaaS scenarios through the OTA(Over The Air) characteristics of software defining hardware, decoupling software and hardware, software evolving and hardware upgrading.

Based on the safe, stable and efficient distributed cloud operating system of the new generation data center, the new generation private cloud realizes the separation of platform and service through the integrated and scene-based design concept, realizes the evolution and light operation and maintenance capability of the whole platform, and helps enterprise users realize the unified architecture from the ready-made hyper-convergence of the 3-node cloud with the most basic unit to the ultra-large-scale cloud platform without upper limit, and maintains a high product experience while based on the open source ecological technology stack, and evolves smoothly and unconsciously through business, data migration and uninterrupted service.

A new generation of private cloud and public cloud enterprises are competing in the field of data center. Non-fragmented version, the continuous evolution of functions is the advantage of public cloud. The new generation private cloud of Yi Jie Nebula Easystack is comparable to public cloud in this respect, but it is more suitable for enterprise users than public cloud in the following aspects:

1. is suitable for complex enterprise data centers. Due to the concentration of software-defined hardware in large-scale data centers, public cloud can only support a single hardware environment and cannot be applied to complex and changeable enterprise data centers. The new generation of private cloud originated from the enterprise data center, with the separation of software and hardware, and the software defines hardware, which "fits" various mainstream hardware forms. However, such a high-complexity product can realize OTA-style online/offline deployment (according to the needs of user laws and regulations).

Second, in terms of scale and architecture, the public cloud started on a large scale. If we adapt to the enterprise user data center in the form of software, except for AWS outpost (not the separation of software and hardware, but the lease and privatization deployment of public cloud), we will not be able to achieve a unified architecture with public cloud from the 10+ node. The new generation of private cloud, from the smallest 3-node scale to unlimited node scale, from cloud-ready hyper-converged form to cloud private cloud form, not only has wider scale flexibility, but also has a unified architecture and integrated design, which lays the foundation for OTA-style smooth and non-inductive evolution.

Thirdly, in terms of operation and maintenance, public cloud relies on a large number of professional operation and maintenance personnel of public cloud enterprises, while the new generation of private cloud is a high-productivity experience, which can be applied to ordinary enterprise data center environment without professional operation and maintenance personnel, and the application threshold is greatly reduced through OTA-style automatic operation and maintenance.

Fourthly, in terms of ecological richness, although public cloud has more partner applications in PaaS/SaaS layer at present, the new generation of private cloud will be based on open source ecological capabilities and will not be dominated by single platform software (such as single public cloud), so it will have more application options than single public cloud in the future.

5. In terms of security compliance, the security compliance requirements of public cloud data in some industries cannot be applied to the core applications of the national economy and people's livelihood industries, but the new generation of private clouds has realized the public cloud experience, and the data ownership belongs to customers, which has a wider scope of application.

6. In terms of business model, on the one hand, the new generation of private cloud can be purchased by license or subscribed, which is essentially different from the subscription service of Red Hat open source version plus professional services, and is more similar to the on-demand payment of public cloud. On the other hand, the expansion of public cloud such as outpost provides a hybrid cloud model with AWS as the core, while the new generation of private cloud is designed for cloudy, which is convenient for users to make different public cloud choices for different public cloud services.
