Alibaba Cloud Fundamentals: ECS, OSS and Regions Explained
How Alibaba Cloud fits together: choosing a region, reading ECS instance type names, picking a billing method, building a VPC and storing data in OSS.
What Alibaba Cloud offers, why its Asia-Pacific coverage and Qwen models matter, how its billing methods work and what to know about mainland China hosting.
Alibaba Cloud is the cloud computing business of Alibaba Group and one of the leading cloud platforms in the Asia-Pacific region. This Alibaba Cloud overview explains its core services, its AI offering built around the Qwen model family, how pricing works and what international users should know. It is most relevant for organizations operating in, or expanding into, mainland China and wider Asian markets.
Alibaba Cloud’s strongest footprint is in Asia. It runs many regions in mainland China, along with regions in Hong Kong, Singapore, Japan, South Korea and several Southeast Asian countries. It also operates regions in Europe, North America and the Middle East, which lets international companies use one provider across markets.
For businesses that need to serve users inside mainland China, having infrastructure there can improve performance and simplify local connectivity. That comes with local regulatory requirements, covered below.
| Service | What it does | Closest familiar equivalent |
|---|---|---|
| Elastic Compute Service (ECS) | Virtual machines in many instance families, including GPU instances | Amazon EC2 |
| Object Storage Service (OSS) | Scalable object storage with several storage classes | Amazon S3 |
| ApsaraDB (RDS, PolarDB and others) | Managed relational databases and cloud-native database engines | Amazon RDS and Aurora |
| Server Load Balancer and VPC | Traffic distribution and private networking | ELB and VPC |
| Container Service for Kubernetes (ACK) | Managed Kubernetes clusters | EKS or GKE |
| CDN and Simple Application Server | Content delivery, plus lightweight bundled servers for simple sites | CloudFront and Lightsail |
The comparison column is only a rough guide; features and limits differ. To learn the basics in more depth, see our guide to Alibaba Cloud ECS, OSS and regions.
Alibaba develops the Qwen family of large language and multimodal models. Developers can access Qwen models through Alibaba Cloud Model Studio, a managed platform for calling models by API, building applications and tuning models. Many Qwen models are also released with open weights, so teams can self-host them on GPU instances. Model availability and features vary by region, so check the Model Studio documentation for your location.
Alibaba Cloud offers several billing methods, and choosing the right one for each resource affects cost significantly:
Be careful when mixing billing methods. Subscription resources are paid in advance and may not be refundable if you release them early, while pay-as-you-go resources keep accruing charges until you delete them. Outbound internet traffic is billed separately, either by bandwidth or by data volume depending on your choice.
Prices differ between regions, and the mainland China site and the international site have separate pricing and accounts.
Regulatory steps in mainland China: websites hosted on servers in mainland China require an ICP filing before they can serve traffic publicly, and some industries need additional licenses. Alibaba Cloud provides an official ICP filing assistance process. Hosting in Hong Kong or other regions avoids ICP requirements, with different latency trade-offs for mainland users.
Two sites: the international site (alibabacloud.com) and the China site (aliyun.com) have separate accounts, verification and documentation. Choose the one that matches where your business operates.
Documentation: English documentation is extensive, but some newer features appear first in Chinese. Real-name verification is required for many services, and default quotas apply to new accounts; request increases through the official quota center.
