FAQ

1.What are the differences between Bare Metal and Cloud Servers?

Comparison Dimension	Bare Metal	VPS
Resource Isolation	Physical-level isolation: Dedicated access to the entire physical server, with no "neighbors."	Virtualization isolation: Shares the underlying physical resources with other tenants through Hypervisor virtualization.
Performance	No performance loss: Direct hardware access with zero virtualization overhead, delivering exceptional, stable, and predictable performance.	Shared performance: Subject to virtualization overhead and may be affected by activity from other instances on the same host ("noisy neighbor" interference).
Security & Compliance	Highest level: Hardware-level isolation, meeting the requirements for data physical isolation and strict compliance in sectors like finance and government.	Software-level isolation: Relies on the virtualization layer and software security groups, suitable for most general security scenarios.
Ops & Management	Self-managed operations: Users have full control from the OS down to the hardware, resulting in higher operational complexity.	Managed operations: The cloud platform manages the underlying hardware and virtualization. Users primarily manage the OS and applications, simplifying operations.
Typical Scenarios	Core databases, High-Performance Computing (HPC), financial trading, high-compliance services, resource-intensive applications.	Websites, development/testing, enterprise applications, businesses requiring rapid and elastic scaling.

2.What is the resource expiration and recycling mechanism?

Before a resource expires, it is recommended that you renew it promptly to avoid data and business loss. The post-expiry handling of relevant resources is as follows:

Resource Type	Within 7 Days After Expiry	7 Days After Expiry
Instance (vCPU, Memory, System Disk, Data Disk, Public IP)	Instance resources (vCPU, memory, system disk, data disk, IP) are retained, but the instance is suspended. If renewed successfully within this period, the instance will resume operation.	Compute resources (vCPU, memory, system disk, data disk, IP) are released. All configurations and data are cleared and cannot be recovered.

Will I be notified before my resources expire?
The system proactively notifies you of resource status changes through the following alerts. It is essential to keep your contact information up-to-date and to check these notifications promptly.

Alert Type	Trigger Time	Delivery Channels
Upcoming Expiry Alert	7 days before resource expiry	In-app message, Email
Expiry Alert	On the resource expiry date	In-app message, Email

We recommend regularly checking resource expiry dates in your console and confirming your contact email is correct, so you don't miss any important updates.

3.Can the configuration of a Bare Metal instance be adjusted?

Bare Metal servers are physical machine instances where users have exclusive access to all hardware resources. Configuration adjustments are not supported.
