• Sound card applications are not supported.

1.4 Network

• Self-plan private network through private network, switch and other functions.

• Self-control traffic through security groups, network ACL and other functions.

• Connect to the public network through EIP, NAT gateway and other functions.

1.5 Mirroring

There are many types and numbers of images, including public images, custom images, shared images, and image market images, to meet the needs of various types of users for rapid deployment and flexible management of application environments.

1.6 Billing method

Supports subscription, pay-as-you-go, and preemptible instance billing methods to meet your needs for cost optimization and flexibility in a long-term period.
1.7 Product Advantages

• Provides a variety of instance specifications, and can flexibly change configurations according to different scenarios.
• Provide comprehensive security solutions and industry solutions.
• Provide rich OpenAPI.
• Support multiple billing methods.
• Provides elastic capacity expansion. Instances and bandwidth can be allocated up or down at any time, and cloud disks can be expanded.

2. Simple Application Server

2.1 Applicable people: Individual developers, students.

2.2 Business Scenarios: Applicable to Simple and low-traffic application scenarios

• Knowledge efficiency management
• E-commerce construction
• Website construction
• Development environment configuration
• Cloud learning environment

2.3 Restrictions on use

• Installation of virtualization software and secondary virtualization are not supported.
• Sound card applications are not supported.
