Huawei Cloud Flexus X Instance: It is a next-gen flexible cloud server service tailored for small and medium-sized enterprises (SMEs) and developers. It offers similar functions to ECS but with added features like flexible vCPU memory ratios, live specification changes, and performance mode support.
Virtual Private Cloud (VPC): An isolated and private virtual network environment that users can apply for on Huawei Cloud. VPC, along with cloud services like Elastic Public IP (EIP), Cloud Connect, and Direct Connect, enables your cloud resources to securely communicate with each other over the Internet and on-premises networks.
Elastic IP (EIP): enables your cloud resources to communicate with the Internet using static public IP addresses and scalable bandwidths. EIPs can be bound to or unbound from ECSs, Bare Metal Servers (BMSs), virtual IP addresses, load balancers, and NAT gateways, to access to or be accessed from the public network.
