Basic Concepts


The computing resources provided by ULightHost are the same as those of Surfercloud UHost. ULightHost is generally suitable for supporting lightweight, low-load, and moderate-traffic application scenarios such as small websites, blogs, forums, cloud development/testing/learning environments.


An image is a template for ULightHost to start and run. The basic image contains the operating system, and the application image contains the basic operating system and pre-installed software.

Currently, ULightHost provides two types of images, basic images and application images:

The network service provided by ULightHost is based on Surfercloud's VPC service. Each ULightHost is assigned 1 internal IP by default after creation, which can be used for communication between different ULightHosts. Under the same account, multiple ULightHosts in the same region are in the same VPC by default, and ULightHosts in different regions are in different VPCs. At the same time, each ULightHost is assigned 1 independent public IP by default after creation, and an exclusive public network bandwidth is configured, which can be used for Internet public network access.


The ULightHost product package includes a certain capacity of system disk storage space, which uses Surfercloud RSSD cloud disk/SSD cloud disk/ordinary cloud disk products. The cloud disk is a highly available, highly reliable, low-cost, customizable block storage device, using a three-copy distributed mechanism, providing low-latency, high random IOPS, and high-throughput I/O capabilities.

The lifecycle of the system disk completely follows the ULightHost, purchased with the ULightHost and used as a system disk, and does not support mounting and unmounting.
