Cloud Auxiliary is a python wrapper and orchestration module for interacting with cloud providers.
CloudAux was initially developed to provide convenience wrappers for common patterns when working with cloud infrastructures (like role assumption, and multi-regionality). It also contained some convenience functions to describe entire resources with the wrappers to fetch the full resource configuration details.
However, over time, we have stopped relying on the resource configuration wrapper capabilities and instead are only supporting the AWS convenience decorators, such as sts_conn, and paginated to name a few. If you wish to make use of CloudAux, simply wrap your boto calls in a function with the decorators applied to them.
Python 2 support has been dropped as of version 1.9.0. For projects that still require Python 2 support, please use the latest 1.8.x builds.
AWS:
- intelligent connection caching.
- handles pagination for certain client methods.
- rate limit handling, with exponential backoff.
- multi-account sts:assumerole abstraction.
- orchestrates all the calls required to fully describe an item.
- control which attributes are returned with flags.
GCP:
- choosing the best client based on service
- client caching
- general caching and stats decorators available
- basic support for non-specified discovery-API services
- control which attributes are returned with flags.
OpenStack:
- intelligent connection caching.
- generalized OpenStack SDK generator usage.
- orchestrates all the calls required to fully describe an item.
- control which attributes are returned flags.
