    The intranet bandwidth and PPS of a FlexusX instance are determined by the instance specifications.
    • Assured intranet bandwidth: the guaranteed bandwidth allocated to a FlexusX instance when there is a network bandwidth contention in the entire network
    • Maximum intranet bandwidth: the maximum bandwidth that can be allocated to a FlexusX instance when the instance does not compete for network bandwidth (other instances on the host do not have high requirements for network bandwidth)
    • Maximum intranet PPS: the maximum capability of FlexusX instances in sending and receiving packets. PPS stands for Packets per Second, indicating the number of packets sent per second. It is usually used to measure the network performance.
    • Maximum NIC queues: allocates NIC interrupt requests to multiple vCPUs for higher PPS performance and bandwidth. For instructions about how to enable NIC multi-queue, see Enabling NIC Multi-Queue.
    • Maximum NICs: the maximum number of NICs that can be attached to a Flexus X instance. An NIC is an elastic network interface. For details, see Elastic Network Interface.
    • Maximum supplementary NICs: the maximum number of supplementary NICs that can be attached to a FlexusX instance. A supplementary NIC is a supplement to NICs. If the number of NICs that can be attached to your instance cannot meet your requirements, you can use supplementary NICs. For details, see Supplementary Network Interface.

EVS offers scalable block storage for FlexusX instances. With high reliability and performance, EVS disks can be used to meet service requirements in various application scenarios. For more information about EVS disk performance, see Disk Types and Disk Performance.

System and data disks of FlexusX instances support the following EVS disk types: common I/O, high I/O, General Purpose SSD, ultra-high I/O, and General Purpose SSD V2. By default, a FlexusX instance has a system disk attached. You can configure the type and capacity of the system and data disks based on service requirements.

FlexusX instances provide the following networking services:

  • Virtual Private Cloud (VPC): allows you to create customized virtual networks in your logically isolated AZ. These networks are dedicated zones that are logically isolated for your FlexusX instances. You can define security groups and IP address segments for a VPC. This facilitates internal network configuration, management, and change. You can also customize the cloud server access rules within a security group and between security groups to strengthen cloud server security protection.
  • Elastic IP: consists of a public IP address and public network outbound bandwidth. After an EIP is bound to a FlexusX instance, the instance can directly access the Internet. FlexusX instances cannot access the Internet if they only have private IP addresses assigned.

Description

Billing Mode

VPC
  • You can customize the VPC for FlexusX instances.
  • In the same region of the same account, all FlexusX instances can communicate with each other over a private network only when they are in the same VPC.
  • FlexusX instances created by different accounts or in different regions are located in different VPCs. They cannot communicate with each other over a private network by default.
  • FlexusX instances in the same region can communicate with each other through VPC Peering Connection, and those in different regions can communicate with each other through Cloud Connect.

Free

EIP

You can purchase an EIP during the instance creation or after the instance is created.

  • You can bind an EIP to or unbind an EIP from a FlexusX instance.
  • The EIP will not be retained after the FlexusX instance is released.
  • FlexusX instances support IPv6 addresses.
  • Yearly/Monthly and pay-per-use billing modes are supported.
  • EIPs can be billed by bandwidth, traffic, or shared bandwidth.
  • The bandwidth size can be changed.

The FlexusX console integrates Cloud Eye, Host Security Service (HSS), and Cloud Backup and Recovery (CBR). You can purchase them together with FlexusX instances on the FlexusX console.

Service

Description

Cloud Eye

Cloud Eye is a multi-dimensional resource monitoring service. You can use Cloud Eye to monitor resource utilization and service running status, and generate alarms to notify you of service exceptions in a timely manner. For more information, see What Is Cloud Eye?

HSS

HSS improves the overall security of FlexusX instances. After HSS is enabled, it scans for weak passwords, system vulnerabilities, brute-force attacks, and unauthorized logins. For more information, see What Is HSS?

CBR

CBR enables you to back up FlexusX instances and disks with ease. In case of a virus attack, accidental deletion, or software or hardware fault, you can restore data to any point in the past when the data was backed up. For more information, see What Is CBR?

Whether Cloud Eye and HSS are displayed on the FlexusX console depends on the selected images. Certain public images do not support Cloud Eye or HSS.
