To facilitate stateless computing, configurations to be migrated are uniformly managed through a profile.

By defining and implementing a profile, the device replacing a damaged device can obtain the same physical attributes of the damaged device.

A computing node can be associated with multiple profiles.

A group of profiles with the same configuration policy corresponds to the stateless device group concept. Configuration policies in the group profile are the same.

Backup management software supports automatic backup.

Backup management software does not support backup for heterogeneous platforms.

Backup management software manages storage media and all backup jobs in a centralized manner.

Backup management software provides a comprehensive log system, enabling administrators to perform monitoring and query operations based on different requirements.

Internal_base is a FusionSphere OpenStack internal management network. Set the network format to tag when creating a network.

External_API is an external API management plane of FusionSphere OpenStack. The FusionSphere OpenStack web client can be accessed from the Internet through External_API.

External_API is an internal OM management plane which allows users to access external networks from internal networks.

Storage_data is an internal storage plane for using KVM resources.

Requirements are transferred through documents, which lacks communication.

The testing automation level is low, quality control and assurance are not complete, and the feedback is slow.

Manual O&M is tedious, complicated, and error-prone. There may be a large number of faults, and the operation duration is long.

The IT staff turnover rate is high, and skills are hard to transfer.

The group management of computing nodes classifies computing nodes with the same configuration policy to the same device group.

eSight detects and limits the resource usage of different computing nodes, ensuring the resource uniqueness.

A computing node can belong to either a device set or a device group.

A group can be associated with multiple group profiles. The member profile of a computing node is generated based on the group profile.
