Simple Application Server:Overview of instance families

Last Updated:Aug 20, 2025

This topic describes all Simple Application Server instance families for purchase and their scenarios, features, and instance types. Refer to this topic to select a suitable instance type when purchasing a simple application server.

Instance families

Simple Application Server provides general-purpose, CPU-optimized, multiple-IP, international, larger-storage, and previous-generation instance families. The following table describes scenarios and features of these instance families.

Type

Scenario

Feature

General-purpose instance families

Website building, web applications, APPs, mini games, self-built game services, application back-end services, development and test environments, cloud learning and training environments, and audio and video servers.

  • Compute: from 2 vCPUs and 0.5 GiB of memory to 4 vCPUs and 16 GiB of memory

  • Storage: from 20 GiB to 80 GiB

  • Network: bandwidth of up to 200 Mbit/s and 1 IPv4 address

CPU-optimized instance family

Small and medium-sized enterprise applications, small and medium-sized database systems, caching, search clusters, game servers, data analysis, and computing.

  • Compute: from 2 vCPUs and 4 GiB of memory to 16 vCPUs and 16 GiB of memory

  • Storage: from 60 GiB to 480 GiB

  • Network: bandwidth of up to 200 Mbit/s and 1 IPv4 address

Important

The CPU-optimized instance family is ideal for enterprise workloads that require guaranteed computing performance. It provides consistent high performance by ensuring full occupation of each hyper-thread.

Multiple-IP instance families

E-commerce account security management, game account security management, short video account security management, and game acceleration

  • Compute: from 2 vCPUs and 0.5 GiB of memory to 2 vCPUs and 2 GiB of memory

  • Storage: from 20 GiB to 40 GiB

  • Network: bandwidth of up to 200 Mbit/s and a maximum of 3 IPv4 addresses

International instance families

Website building, websites for e-commerce enterprises, web applications, APPs, mini games, self-built game services, application back-end services, development and test environments, audio and video servers, and cloud learning and training environments

  • Compute: from 2 vCPUs and 0.5 GiB of memory to 4 vCPUs and 16 GiB of memory

  • Storage: from 20 GiB to 80 GiB

  • Network: Network: bandwidth of up to 200 Mbit/s, 1 IPv4 address, and Border Gateway Protocol (BGP) (non-China-optimized) ISPs (Internet service providers).

    Important

    International instance families use BGP (overseas optimized) ISPs. This can cause high Internet latency and packet loss rate to users in the Chinese mainland. If your business provides services to users in the Chinese mainland, do not select international instance families.

Larger-storage instance families

Private cloud storage, cloud learning and training environments

  • Compute: from 2 vCPUs and 2 GiB of memory to 4 vCPUs and 16 GiB of memory

  • Storage: from 60 GiB to 300 GiB

  • Network: bandwidth of up to 200 Mbit/s and 1 IPv4 address

Previous-generation instance families

Website building, web applications, APPs, mini games, self-built game services, development and test environments, cloud learning and training environments, audio and video servers, and application back-end services

  • Compute: from 2 vCPUs and 0.5 GiB of memory to 4 vCPUs and 16 GiB of memory.

  • Storage: from 40 GiB to 400 GiB.

  • Network: bandwidth of up to 30 Mbit/s and 1 IPv4 address.

Instance type metrics

Metric

Description

Instance type

The ID of the instance type. Instance types are available for Linux or Windows and used for API calls.

  • Linux instance types: In the format of swas.*.*.linux or swas.*.*.un.

  • Windows instance types: In the format of swas.*.*.win or swas.*.*.nt.

  • Linux and Windows instance types: Instance types without the above suffixes support both Linux and Windows.

vCPU

Alibaba Cloud assigns simple application servers of different computing performances based on resource availability. The vCPU is not guaranteed.

General-purpose, multiple-IP, international and larger-storage instance families are not suitable for workloads that require strong and consistent compute performance. If resource contention occurs during peak hours, the computing performance may deteriorate.

CPU-optimized instance family are ideal for enterprise workloads requiring guaranteed compute performance, as they ensure full utilization of each hyper-thread and deliver consistent high performance.

Memory

Indicates all available memory(including system data), such as the reserved memory for BIOS and the overheads for the kernel and Hypervisor. The available memory size that you view is smaller than the memory defined for the instance type.

Storage

Alibaba Cloud assigns simple application servers of different storage sizes to you based on resource availability. The storage is not guaranteed. Simple application servers are not suitable if you have strict requirements for storage performance.

Transfer

The monthly quota of free Internet data transfers. The data transfers are free of charge for the instance types that do not contain a monthly quota.

Bandwidth

The maximum rate of inbound or outbound Internet data transmission. This metric is not guaranteed. During peak hours, if resource contention occurs, bandwidth may be limited, and packet loss may occur. Simple application servers are not suitable for scenarios with strict requirements for Internet connection quality. If your business requires high-quality Internet connections, we recommend purchasing Elastic Compute Service instances that use pay-by-bandwidth billing.

ISP

  • BGP networks allow users of different ISPs to access simple application servers at a high speed.

  • International instance families use BGP (overseas optimized) ISPs. This can cause high Internet latency and packet loss rate to users in the Chinese mainland. If your business provides services to users in the Chinese mainland, do not select international instance families.

Public address

You cannot change the public IP address of a simple application server. If you cannot connect to a specific website or application, we recommend that you request a refund for the current simple application server and purchase a new one.

Region

The regions that the instance type is supported.

References

If the computing resources (vCPUs and memory), storage resources (system disk capacity), and network resources (data transfer quota and bandwidth) of your purchased server do not meet your requirements, you can upgrade your plan. For information about the upgrade limits and operations, see Upgrade configurations.
