Many of Alibaba Cloud services provide highly reliable data storage capacity. For example, Object
Storage Service (OSS) promises that its data reliability is no less than 99 99999999%. This high data
reliability is solely achieved by RAID 0+1 redundancy technology.
Auto Scaling can automatically adjust the number of ECS instances based on user-defined scaling
rules to meet service needs. If a user cannot predict service changes or does not have enough history
data, he/she can still use dynamic scaling mode to automatically add/remove ECS instances based on
certain CloudMonitor performance metrics (such as the CPU utilization rate)
All RDS for MySQL backups are full backups.
The Alibaba Cloud CDN can directly accelerate access to the files stored in OSS and reduce OSS traffic
Different Alibaba Cloud VPCs are completely isolated from each other.
By default, the VPCs cannot communicate with each other over Intranet, but you can establish VPN
connections via the Internet to achieve interconnection between VPCs.
After stopping an Alibaba Cloud Elastic Compute Service (ECS) instance, since the ECS instance is
stopped, you will not be charged for anything related to that ECS instance until you start the instance
again regardless of which region the instance is located in.
Once ECS is created, you can't change its private IP address anymore.
Alibaba Cloud provides comprehensive security protection covering networks, hosts, applications,
databases, and content for on-cloud clients. Users using Alibaba Cloud services only need to focus on
their own services, without the need to pay any attention to security protection issues.
Names of the files in each OSS bucket must be unique Also, they can be renamed.
When using Alibaba Cloud SLB, users can enable the health check function If a backend ECS instance
A is running abnormally, SLB will isolate it and forward the requests to other ECS instances, and when
the backend ECS instance A is back to normal, SLB will again forward requests to it.
