This topic describes how to use an accelerated endpoint of Object Storage Service (OSS) together with Function Compute and Serverless workflow to build a low-cost and highly efficient cross-border system of synchronized object transfer.
Scenarios
- Cross-border transfer of object data is required.
- The cost of cross-border data transfer must be strictly controlled.
- Your applications are latency insensitive, and you can accept the synchronization latency caused by network jitters.
- The system that is used to transfer data is elastic and can be scaled to handle large-scale file writes.
Solution overview
The following figure shows the architecture of the solution.
The following items describe the details:
- Elastic Compute Service (ECS) simulates applications to access OSS buckets in the China (Shanghai) and US (Silicon Valley) regions to produce and upload content.
- The content is uploaded to OSS buckets in China (Shanghai) by using an internal same-region endpoint.
- When an object is uploaded to an OSS bucket in China (Shanghai), Function Compute invokes a Serverless workflow. Each workflow uploads an object. This ensures that the object can be quickly synchronized by using the accelerated OSS endpoint in US (Silicon Valley).
- ECS simulates local users in US (Silicon Valley) to read OSS objects and check whether the data is correct.
Benefits
- Low O&M costs: Developers can focus on the code logic.
- Low network cost: Compared with the combination of Express Connect and Cloud Enterprise Network (CEN), this solution is more cost-effective.
- Low deployment cost of synchronization services: After an object is uploaded to an OSS bucket, Function Compute invokes a Serverless workflow. Serverless workflows are triggered on demand. You do not need to prepare ECS resources.
- High elasticity and efficiency: One object triggers one Serverless workflow task. This ensures that resources are fully utilized and synchronization is performed in an efficient manner.
