Instance specification metrics
Metric | Description |
Instance type | The instance type ID is used for OpenAPI calls and distinguishes between Linux and Windows instances.
|
vCPU | Simple Application Server instances are allocated from available inventory. Performance levels and CPU models are not guaranteed. General-purpose, multi-public IP, international, and storage-optimized instance types are not suitable for applications that require guaranteed computing performance. Performance can fluctuate during peak hours due to resource contention on Alibaba Cloud. For enterprise applications that require guaranteed computing performance, use CPU-optimized instance types. These instances ensure full hyper-threading utilization to deliver consistently high performance. |
Memory | The listed memory size is the total memory available. This includes memory used by the system for BIOS, kernel, and hypervisor operations. Therefore, the actual available memory will be less than the specified amount. |
System disk capacity | System disks with different performance levels are allocated based on inventory. These disks are not suitable for applications that require guaranteed storage performance. |
Internet traffic package | This is the monthly free quota for Internet traffic. No traffic fees are charged for instance types that do not include a fixed traffic package. |
Peak Internet bandwidth | This is the maximum peak bandwidth for both inbound and outbound Internet traffic. This is not a guaranteed performance metric. During peak hours on Alibaba Cloud, resource contention can limit bandwidth and cause packet loss. Therefore, these instances are not suitable for applications that require guaranteed Internet quality. If your application has this requirement, purchase an Elastic Computing Service (ECS) instance with a fixed Internet bandwidth billing plan. |
Public network line type |
|
Fixed public IP address | The public IP address cannot be changed separately. If you cannot connect to a specific website or application, request a refund and purchase a new Simple Application Server. |
Region | The regions where this instance type is available. |

If your server configuration does not meet your business needs, you can upgrade its resources. You can upgrade compute resources (vCPUs and memory), storage resources (system disk capacity), and network resources (data transfer quota and public bandwidth). For more information about upgrade limitations and instructions, see Upgrade configuration.
