Huawei Cloud Flexus X-instance Cloud Server:

Flexus X-instance Cloud Server is a new generation of flexible computing cloud servers designed for SMEs and developers. Its functionality is similar to ECS, while also featuring unique characteristics such as more flexible vCPU-to-memory ratios, support for hot reconfiguration without service interruption, and performance modes.

Virtual Private Cloud (VPC):

A Virtual Private Cloud (VPC) is an isolated, private virtual network environment provisioned by users on Huawei Cloud. Users can build independent cloud-based network spaces using VPCs, and integrate them with services like Elastic IP (EIP), Cloud Connect, and Cloud Direct Connect to enable communication with the Internet, private cloud networks, and cross-cloud private networks, helping you build a reliable, stable, and efficient dedicated cloud network.

Elastic IP (EIP):

Elastic IP (EIP) provides independent public IP resources, including public IP addresses and outbound bandwidth services. It can be flexibly bound or unbound to resources such as Elastic Cloud Servers, Bare Metal Servers, Virtual IPs, Elastic Load Balancing, and NAT Gateways, offering the ability to access and be accessed via the public network.

Resource Orchestration Service (RFS):

Resource Orchestration Service (RFS) is a stateful orchestration engine newly added to Application Orchestration Service, fully supporting the industry-standard Terraform (HCL + Provider). It is used to manage system resources and service resources. RFS employs templates based on the open ecosystem HCL syntax, automating the deployment of specified cloud service resources according to the template
