CloudPond allows you to run core cloud services on premises, including Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Virtual Private Cloud (VPC), and Elastic IP. In addition to core cloud services, you can deploy additional cloud services as required.
LVS Load Balancing Test Objectives LVS can evenly forward requests to two backend server nodes. Prerequisites The LVS environment of the test cluster has been configured. The web test service has been deployed on the primary and standby backend nodes. Install the httpd service on
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP, and Image Management Service (IMS), are shared within the same cloud region.
LVS Automatically Managing Recovered Nodes Objectives After the faulty node in the backend service cluster is recovered, LVS automatically manages the recovered node. Prerequisites The LVS environment of the test cluster has been configured. Test Methods Restart the stopped node,
Core cloud services include ECS, EVS, VPC, and EIP. These services allow you to use compute and storage resources on premises. You can also deploy applications from the KooGallery on the edge site to seamlessly extend the Huawei Cloud ecosystem to the edge (coming soon).
Installing Tools on LVS Nodes Run the following commands in sequence to install tools on LVS nodes: yum insatll keepalived yum install ipvsadm yum install ipvs-fnat yum install ipvs-fnat-tools Run these commands on both primary and standby LVS nodes. Parent topic: Configuration Preparations
LVS Load Balancing LVS FULLNAT mode: DNAT is performed on packets to change VIP VPORT to RIP RPORT, and SNAT is performed to change CIP CPORT to LIP LPORT. The packet is forwarded to the RealServer for processing. NAT is performed in the opposite direction to send packets returned
