07FAQ · COMMON QUESTIONS
Frequently Asked Questions
- 01What is an elastic cloud server?
It pools compute resources in the cloud and provisions servers on demand with full control, distributed storage, free backup, pay-as-you-need purchasing and smooth upgrades.
- 02Can I scale flexibly and buy on demand?
Yes. vCPU, disk and bandwidth can each be scaled independently without changing plans.
- 03Can I add dedicated IP addresses?
Some facilities support additional dedicated IPs, currently quoted at 580 CNY/IP/year — subject to the order page.
- 04Can lost website data be recovered?
Data is kept in 4 real-time replicas with daily system backups; basic snapshot keeps 2 copies, advanced keeps 5, and custom snapshot rollback is supported.
- 05Can I buy without technical skills?
Yes. The control panel and site assistant cover common ops; non-technical users should pick the Windows image with site assistant and SQL Server preinstalled.
- 06What are the steps to build a website?
- 07How to tell real cloud computing from fake?
Check for distributed storage, failover, live migration and elastic scaling — a real cloud platform has all of them.
- 08Local storage or distributed storage?
All distributed storage with 4 real-time replicas, avoiding data loss from a single disk failure.
- 09If a physical server fails, can it switch quickly with the same IP?
Yes — fast failover and live migration without downtime, and the IP stays unchanged.
- 10Will physical server maintenance interrupt my cloud server?
Usually not. Servers are live-migrated to other nodes before maintenance.
- 11Is there a private intranet between multiple cloud servers?
Private intranet interconnection is supported by default, with a free virtual switch.
- 12How long is the downtime when scaling memory, disk or bandwidth?
Memory, bandwidth and vCPU scale both ways; disks can only grow. One reboot is required, about 1 minute of interruption.
