FlexusX Instance Purchase

When purchasing a FlexusX instance, you need to configure the instance specifications, image, storage, network, and security group. After the purchase is successful, you can use the FlexusX instance on the cloud just like using a local PC or physical server.

For details, see Purchasing a FlexusX Instance.

FlexusX Instance Login

After a FlexusX instance is created, you can log in to the instance and deploy websites or applications on it. FlexusX instances support multiple login modes. You can select a login mode as required.

For details, see Login Modes.

Password Reset

If you did not set a password when creating a FlexusX instance, if you have forgotten the password, or if the password has expired, you can reset the password on the management console.

For details, see Resetting the Password for a FlexusX Instance.

OS Change

If the OS of a FlexusX instance is abnormal or requires optimization, you can reinstall the OS to restore or optimize the OS.

If the OS running on your FlexusX instance cannot meet service requirements, you can change it to another OS version or type.

For details, see Changing the OS of a FlexusX Instance.

Specification Modification

If the FlexusX instance you purchased cannot meet service requirements, you can modify the specifications by upgrading the vCPUs and memory or change the instance to an ECS.

For details, see Modifying the Specifications of a FlexusX Instance.

Performance Mode

FlexusX provides flexible compute resources with QoS-guaranteed performance. FlexusX instances perform as well as exclusive instances most of the time but may occasionally underperform. To meet the strict performance requirements of certain workloads, such as rendering and HPC applications, FlexusX has a performance mode option. If this option is enabled, your FlexusX instances are bound with the underlying CPU cores, so they can provide stable, fantastic QoS-guaranteed performance.

For details, see Enabling Performance Mode for a FlexusX Instance.

Image Management

FlexusX instances can be created from public, private, and shared images. You can use a private image to quickly create FlexusX instances with the same configurations as the image or use the image to change the OS of a FlexusX instance.

For details, see Image Overview.

EVS Disk Management

Elastic Volume Service (EVS) provides scalable block storage for FlexusX instances. With high reliability, high performance, and varied specifications, EVS disks can be used for distributed file systems, development and testing environments, data warehouses, and high-performance computing (HPC) scenarios to meet diverse service requirements.

For details, see EVS Disk Overview.

VPC Management

Virtual Private Cloud (VPC) allows you to provision logically isolated virtual networks for your FlexusX instances. You can define security groups and CIDR blocks for each VPC. This facilitates internal network configuration, management, and change. You can also define rules to control communications between FlexusX instances in the same security group or across different security groups.

An elastic network interface (ENI) is a virtual network card. You can create network interfaces and attach them to your FlexusX instances to obtain flexible and highly available network configurations.

For details, see VPC Overview.

EIP Management

The Elastic IP (EIP) service enables your cloud resources to communicate with the Internet using static public IP addresses and scalable bandwidths. You can easily bind or unbind EIPs to or from FlexusX instances, ECSs, BMSs, virtual IP addresses, NAT gateways, and load balancers as needed. There are different billing modes to meet different service requirements.

For details, see EIP Overview.

Security Group Management

A security group is a collection of access control rules for cloud resources, such as cloud servers, containers, and databases, that have the same security protection requirements and that are mutually trusted. After a security group is created, you can configure access rules that will apply to all cloud resources added to this security group.

For details, see Security Group Overview.

HSS

HSS is designed to improve the overall security for cloud servers. It helps you identify and manage the assets on your servers, eliminate risks, and defend against intrusions and web page tampering. There are also advanced protection and security operations functions available to help you easily detect and handle threats.

For details, see Configuring HSS for a FlexusX Instance.

Backup Management

Cloud Backup and Recovery (CBR) enables you to back up cloud servers and disks with ease. In the event 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 details, see Backup Overview.

Monitoring

Monitoring is critical to ensuring the reliability, availability, and performance of FlexusX instances. It allows you to view instance resources and learn instance statuses in real time. You can use Cloud Eye to automatically monitor FlexusX instances in real time and manage alarms and notifications. This helps you keep track of performance metrics of FlexusX instances.

For details, see Server Monitoring Overview.
