CloudBridge

CloudBridge provides a consistent, extensible Python API that abstracts interactions with multiple Infrastructure-as-a-Service (IaaS) cloud providers to enable portable deployment of computational applications and scientific workflows.

Key Features:

• Open-source Python library: Implements cloud abstraction primitives as an open-source Python library.
• Multi-cloud abstraction: Provides a consistent layer of abstraction over different IaaS cloud providers.
• Uniform and extensible API: Exposes a uniform, extensible API that standardizes interactions with multiple cloud services.
• Provider contract: Defines a provider "contract" that supported providers must implement to ensure consistent behavior.
• Conformance tests: Includes a suite of conformance tests to verify that providers adhere to the defined contract.
• Eliminates cloud-specific code: Reduces the need for conditional, provider-specific coding by offering standardized interfaces.

Scientific Applications:

• Portable research workflows: Enables deployment of computational research workflows across multiple IaaS providers without provider-specific code changes.
• Resource-agnostic analyses: Allows scientific analyses to be executed on different cloud infrastructures by standardizing cloud service interactions.
• Provider validation and comparison: Facilitates verification and comparison of IaaS provider implementations via conformance testing.

Methodology:

Implements a uniform, extensible API and a provider "contract" that abstracts vendor APIs, and uses an extensible suite of conformance tests to verify provider adherence to that contract.
