Data Portability and AI Workloads with Airbyte using Iceberg

Moving AI workloads between clouds is a nightmare for data teams, highlighting the critical importance of data portability. Massive datasets create “data gravity” that locks you into a single cloud provider, limiting flexibility and innovation.

Each major cloud—AWS, Azure, and Google Cloud—has its own architecture, APIs, and services. Build around Lambda or BigQuery, and you’re trapped. As CloudTweaks points out, these incompatibilities constitute a significant blocker to multi-cloud strategies.

Switching environments means costly, time-consuming rebuilds. Proprietary formats, schema mismatches, and slow, expensive transfers make it worse. According to Intelligent CIO, these factors quickly drain AI budgets at scale.

Worse, ML models trained on one provider’s infrastructure can underperform elsewhere, tying your stack to a single vendor.

Cloud sprawl is inevitable. Data portability isn’t optional—it’s the foundation for adapting and scaling AI workloads. The European Union’s General Data Protection Regulation (GDPR) underscores this by establishing the framework for individuals to access, move, and manage their personal data across different services. It emphasizes compliance and the implications for both data processors and users within the EU.

That’s where Apache Iceberg comes in. It was built to solve exactly this by leveraging an application programming interface (API) to enable data exchanges and enhance interoperability between different software systems.

Understanding Data Portability

Data portability refers to the ability to move data seamlessly among different applications, programs, computing environments, or cloud services. It is applicable when the processing of personal data is executed by automated means, highlighting the necessity of consent or a contractual basis between the data subject and the data controller. In the context of cloud computing, it allows customers to migrate their data and applications between or among cloud service providers (CSPs) without losing access to their valuable information. 

This capability is crucial for organizations that store large quantities of data in the cloud. It ensures they can switch between CSPs as needed, maintaining continuous access to their data and services. 

By enabling this fluid movement, data portability supports flexibility and adaptability in managing AI workloads and other data-intensive operations.
