You can access other services, such as Alibaba Cloud Object Storage Service (OSS), Message Service (MNS), databases, user-created HTTP services, and Function Compute itself (for example, invoking or triggering a function), in the same way that you access them on your local machine. Function Compute provides only a runtime environment. To access services from Function Compute, compress the required dependent libraries and your function code into a package and upload the package. For more information about how to compress the dependencies and code into a package, see Install third-party dependencies.
