The following explain relevant cloud services.

Elastic IP (EIP): EIP provides static public IP addresses and scalable bandwidths that enable your cloud resources to communicate with the Internet. You can easily bind an EIP to an ECS, BMS, virtual IP address, NAT gateway, or load balancer, enabling immediate Internet access.
Virtual Private Cloud (VPC): VPC allows you to isolate online resources with virtual private networks. It enables your cloud resources to securely communicate with each other, the Internet, and on-premises networks.
Elastic Cloud Server (ECS): ECS provides secure, scalable, on-demand compute resources, enabling you to flexibly deploy applications and workloads.
Flexus X Instance (FlexusX): FlexusX is a next-generation flexible cloud server service designed for small- and medium-sized enterprises (SMEs) and developers. FlexusX provides functions similar to what ECS provides. It supports flexible vCPU/memory ratios, performance mode, and live specification change.
