Feature Description Release date References
Insights Insights summarizes the execution status of function requests. After Insights is enabled, the system collects metrics about each execution of a function. The metrics include performance metrics such as memory usage, function execution duration, initialization duration, and cold starts, and exception metrics such as failed executions and error details. The metrics also include tracing metrics such as tracing details and whether sampling is performed. These metrics are delivered to the Logstore that you specified when you configured logging. Insights monitors each invocation of a function to provide information about the execution of the function. 2020-11-30
Image pull acceleration Compared with function code packages, container images are easier to be migrated between technology stacks. In addition, container images feature a comprehensive and standard tool chain ecosystem and provide best practices. However, container images contain files that are not used by applications, such as operating systems and command tools. These files inevitably increase the amount of data to be downloaded and decompressed, and prolongs the cold start for functions. It can take quite a few minutes to pull a large image whose size is larger than 1 GB before decompression. This greatly deteriorates the cold start performance of function instances. To resolve this issue, Function Compute has made a series of optimizations to improve the pull speed of container images by two to five times in different scenarios. The amount of time consumed to pull an image is reduced from minutes to seconds. 2020-11-30 Image pull acceleration
Application Real-Time Monitoring Service (ARMS) advanced monitoring Function Compute seamlessly integrates with ARMS. You can use the application performance management (APM) feature of ARMS by configuring environment variables. ARMS provides non-intrusive advanced monitoring without code changes for applications in the Java 8 runtime environment. This way, you can view various metrics of instances, such as the total number of requests, the response time, and errors. 2020-11-30 Monitor Java functions
Auto scaling of provisioned instances Auto scaling of provisioned instances is supported. You can perform scheduled auto scaling or metric tracking auto scaling to make better use of provisioned instances. 2020-11-30 Auto-scaling of reserved instances
Resource plans Resource plans are supported. The resource plans contain different types of instances. When you use Function Compute, the instances that are used are first deducted from the resource plan within the validity period of the resource plan. The excess usage is charged in pay-as-you-go mode. 2020-11-30 Resource package
Programming model extensions The runtime extension feature is provided to resolve the following pain points. The feature extends the existing programming model for HTTP servers by adding the PreFreeze and PreStop webhooks to the existing HTTP server model. Extension developers implement an HTTP handler to monitor lifecycle events of function instances. The programming model extensions resolve the following pain points:
  • Data of asynchronous background metrics is delayed or lost.
  • The latency is increased if metrics are synchronously sent.
  • Graceful release of functions is required.

Custom container images In the cloud-native era, container images have become a standard tool for software deployment and development. Function Compute provides a custom container runtime to improve developer experience and the development and delivery efficiency. Developers can deliver their functions as container images and interact over HTTP with Function Compute. The custom container runtime simplifies the following scenarios:
  • You can perform cost-effective migration and maintain consistency between development and production environments without modifying code or recompiling binary and shared objects (*.so).
  • Compressed images can be up to 1 GB in size. This allows you to package code and dependencies together for easier distribution and deployment.
  • Container images are natively stored in a cache hierarchy. This improves the efficiency of uploading and pulling code.
  • Standard, replicable third-party libraries can be used for referencing, sharing, building, code uploading, storage, and version management. This offers a comprehensive open source ecosystem for CI/CD.
Tracing Analysis Tracing Analysis in Function Compute connects the entire trace. It provides the following core features:
  • Automatically records the amount of time that is spent on key steps in Function Compute.
  • Connects to an upstream service. If a request header contains a SpanContext, Function Compute creates a child span based on the SpanContext.
  • Connects to a downstream service. Function Compute imports the SpanContext to the function context to help you track the internal trace of a function.
  • Allows you to view application topologies.
  • Allows you to view the execution of an invalid API operation and identify the cause of the error.
