<p><strong>Exclusive Resources</strong></p> <p>After you buy a Dedicated Host, you have the exclusive use of the resources (including CPU, memory, and disks) on this host. All those resources are isolated from other users.</p> <p><strong>Flexible Specifications</strong></p> <p>You can select instance specifications with multiple CPU-to-memory ratios to meet diverse needs.</p> <p><strong>Independent Planning</strong></p> <p>A Dedicated Host allows you to customize instances on it. Instances on the Dedicated Host are not charged. The number of instances you can run on a Dedicated Host is mainly determined by the resources available on the Dedicated Host.</p> <p><strong>Secure and Reliable</strong></p> <p>Dedicated Hosts can be deployed in multiple regions, zones, and pods to ensure disaster recovery, data backup, and high availability.</p> <p>A Dedicate Host supports the lifecycle management. In addition, you can use the cloud monitoring service Argus to monitor the CPU, memory, disks, agent survival, and other performance indicators of the Dedicated Host. Dedicated ECS instances created on the Dedicated Host support the following features: lifecycle management, resource monitoring, images, snapshots, operation and maintenance, support for VPC, and dedicated disk mounting.</p> <p>&bull;&nbsp;&nbsp;&nbsp;&nbsp; <strong>Lifecycle management</strong></p> <p>Similar to common ECS instances, dedicated ECS instances support the following operations: creation, stop, start, capacity expansion and reduction, release, and resetting passwords.</p> <p>&bull;&nbsp;&nbsp;&nbsp;&nbsp; <strong>Resource monitoring</strong></p> <p>You can use the cloud monitoring service Argus to monitor the CPU, memory, disks, network, and other performance indicators of dedicated ECS instances and set alarm templates.</p> <p>&bull;&nbsp;&nbsp;&nbsp;&nbsp; <strong>Creating images</strong></p> <p>You can create a system image for a dedicated ECS instance and use custom images to clone ECS instances for rapid deployment.</p> <p>&bull;&nbsp;&nbsp;&nbsp;&nbsp; <strong>Creating</strong><strong> snapshots</strong></p> <p>Custom snapshot policies for rollback of dedicated disks greatly guarantees data consistency.</p> <p>&bull;&nbsp;&nbsp;&nbsp;&nbsp; <strong>Operation and maintenance</strong></p> <p>To manage a dedicated ECS, you can configure an Internet connection to remotely log in to the ECS or connect to the ECS through the remote console. The remote console is a cloud host rescue option when the remote connection to the ECS fails. Similar to common ECS, dedicated ECS provides security features including Ping An Host Security (PHS) and DDoS protection.</p> <p>&bull;&nbsp;&nbsp;&nbsp;&nbsp; <strong>Support for VPC</strong></p> <p>Similar to common ECS, dedicated ECS supports secure isolation based on the Ping An Cloud VPCs. You can configure a NAT gateway for Internet connection, a VPN for local IDC interconnection, and an express connect for cross-VPC communication. You can add dedicated ECS instances to the ELB backend resource pool to ensure load balancing and high availability, and use security groups to isolate them.</p> <p>&bull;&nbsp;&nbsp;&nbsp;&nbsp; <strong>Dedicated disk mounting</strong></p> <p>To meet the requirements of the scalable storage, you can mount dedicated disks (local disks) to a dedicated ECS instance or unmount them from the instance.</p>
