Using Lite Server

ModelArts Lite Server provides various resources, allowing you to install and deploy third-party software such as AI frameworks and applications as user root, as well as building a dedicated cloud server environment. To create a server and obtain the required physical resources on the cloud for daily training and inference, you only need to specify the server specifications, image, network configuration, and key.

This document helps you understand how to use Lite Server.

Purchasing resources
To use Server resources, you need to purchase them first.
1. Contact the customer manager to determine a resource solution. Apply for the required resource specifications since certain specifications are restricted.
2. The default resources provided by the cloud services, such as elastic cloud server (ECS), elastic IP (EIP), and Scalable File Service (SFS), may not meet your requirements. Submit a service ticket to increase resource quota.
3. Grant the required basic permissions to the IAM user.
4. ModelArts needs to access other dependent services. Create an agency for ModelArts.
5. Purchase Lite Server resources on the ModelArts console.
Configuring resources
After acquiring resources, set up network, storage, and drivers.
Using resources
Log in to the server for model training and inference. For details, see Using Lite Server Resources.
Managing resources
Lite Server allows you to start, stop, and switch OSs. You can manage resources on the ModelArts console.

Term	Description
BMS	Combining VM scalability with physical server performance, BMS provides dedicated cloud servers. These servers are designed to meet the demands of computing performance and data security for core databases, critical applications, high-performance computing (HPC), and big data. After you purchase Lite Server on the ModelArts console, a BMS corresponding to it will be created on the BMS console as Lite Server is a BMS. You can mount disks and bind EIPs on the BMS console. For more information about bare metal servers, see Bare Metal Server.
Key Pair	You can log in to an elastic server using only an SSH key pair. Therefore, you do not need worry about password interception, cracking, and leakage. NOTE: To ensure ECS security, private keys that are not managed by Huawei Cloud can be downloaded only once. Keep your downloaded private keys properly.
VPC	A VPC is a logically isolated, configurable, and manageable virtual network. It helps improve the security of cloud resources and simplifies network deployment. Within your own VPC, you can create security groups and VPNs, configure IP address ranges, and specify bandwidth sizes by customizing security groups, VPNs, IP address ranges, and bandwidth. This simplifies network management. You can also customize access rules to control BMS access within a security group and across different security groups to enhance BMS security. For details, see Virtual Private Cloud.
