Proxy settings

Scenarios

• Restricted network access: If your application runs in an environment that requires a proxy server to reach external networks, such as an enterprise intranet or a firewall-restricted network, you can configure a proxy to access Alibaba Cloud services.

• Traffic monitoring: During development or testing, you can use a proxy to capture and analyze request traffic for troubleshooting.

Examples

• An application deployed on an enterprise intranet uses an HTTP or HTTPS proxy to access Alibaba Cloud services.

• Multiple applications in an enterprise share a proxy server that manages and routes requests to external services.

For more information, see Configure a proxy.

SSL authentication settings

Scenarios

• Network security: Verify SSL certificates in HTTPS requests to ensure secure communication.

• Disable authentication (not recommended): In some scenarios, such as environments that use self-signed certificates, you can temporarily disable SSL authentication.

Examples

• By default, SSL authentication is enabled to secure communication between your application and Alibaba Cloud.

• During development or debugging, you may need to disable SSL authentication to bypass certificate issues. Make sure that you re-enable SSL authentication in your production environment.

For more information, see Configure SSL authentication.

Timeout settings

Scenarios

• Network stability: When network latency is high or server responses are slow, a proper timeout prevents requests from hanging indefinitely.

• User experience: A proper timeout for user-facing applications prevents prolonged waits when a service is unavailable.

Examples

• If the network connection drops while uploading large files to OSS, a proper timeout terminates the stalled request so the user can retry the upload.

• For time-consuming API operations such as batch operations, a proper timeout prevents requests from waiting indefinitely.

For more information, see Configure a timeout period.

Log settings

Scenarios

• Record request and response details to help troubleshoot API failures such as signature errors and missing parameters.

• Analyze log data to monitor key metrics such as request duration and success rate, helping you identify performance issues.

Examples

• If creating Elastic Compute Service (ECS) instances fails, you can check the logs to verify whether the HTTPS request signature is valid and whether parameters are correctly configured.

• Identify performance bottlenecks by monitoring the duration of Object Storage Service (OSS) upload API operations.

For more information, see Configure a logger.

Asynchronous call settings

Scenarios

• High concurrency: When you need to process many concurrent tasks, asynchronous operations can significantly improve throughput.

• Non-blocking operations: For time-consuming operations, asynchronous calls keep the main thread responsive by running tasks without blocking.

Examples

• When creating multiple ECS instances, you can send requests asynchronously to reduce total wait time.

• When uploading a large number of files, you can use asynchronous operations to fully utilize the coroutine pool and increase throughput.

For more information, see Use the asynchronous calls feature.
