Data Plane Assurance

Load balancing distributes traffic, preventing single points of failure and improving system reliability.

Computing nodes are in isolated VPCs, strictly separated from external networks for security.

By default, functions have public access, but users can configure access to specific VPC resources.

The multi-cluster and multi-AZ architecture allows resource migration during AZ fault, ensuring continuous operations.

The intelligent algorithm predicts traffic and automatically scales up resources to quickly respond to burst traffic.

Function instances are classified into elastic and reserved instances. Elastic instances can be dynamically created based on real-time service load changes and automatically released during off-peak hours to avoid resource waste. Reserved instances are configured and created in advance by users based on service requirements and are not automatically released. You can set the maximum number of elastic and reserved instances based on service requirements.

Requests are processed directly without caching, suitable for scenarios requiring high real-time performance.

Requests are cached in message queues to guarantee execution. Queues are isolated by account or function to avoid data interference among users. The system retries failed invocations up to three times by default. And you can customize the retry times.

FunctionGraph regularly scans and fixes vulnerabilities in compute nodes and function instances, ensuring a secure and stable runtime environment.

The code modification takes effect only for newly generated instances and does not affect running instances, ensuring code consistency and stability.

File systems and memory are released together with the instance, preventing data residue and enhancing resource utilization.

The runtime environment automatically collects exceptions and logs to help quickly identify and resolve issues, improving troubleshooting efficiency.
