Frequently asked questions

What is the difference between managed and self-hosted ML platforms?

Managed platforms like Vertex AI and SageMaker handle infrastructure, scaling, and maintenance for you, enabling faster deployment but with higher costs and vendor lock-in. Self-hosted or open source platforms like H2O and Lightning AI offer more control and flexibility but require more DevOps expertise and infrastructure management.

Which platform is best for training large language models?

Google Cloud Vertex AI, AWS SageMaker, and Databricks offer the best distributed training infrastructure at scale. Hugging Face provides excellent pre-trained models and fine-tuning infrastructure, making it ideal if you're working with existing transformer models rather than training from scratch.

How do I choose between cloud providers (Google, AWS, Azure)?

Consider your existing cloud investments first. Google Cloud Vertex AI excels in AI research, AWS SageMaker offers the broadest integration with AWS services, and Azure ML integrates best with Microsoft tools. If you have no preference, evaluate each platform's free tier to determine which interface and documentation suit your team best.
