Career path: ML engineer → ML systems engineer → platform engineer. High-value niche: companies doing serious ML need Ray expertise. Salaries: $140k-280k+.

What is Anyscale Ray Platform

Ray is an open-source distributed computing framework for Python. Run code on clusters (1-1000s nodes) with minimal changes. Anyscale is the managed platform (SaaS) running Ray on cloud infrastructure. Use for: distributed ML training, hyperparameter tuning (Ray Tune), batch processing, real-time serving (Ray Serve), reinforcement learning.

❓ FAQ

Should I use Ray or Kubernetes for ML?

Ray is higher-level, abstracts cluster management. Kubernetes is lower-level, more control. If doing pure ML/data: Ray. If managing complex infra: Kubernetes. Many teams use both (Ray on top of Kubernetes).

Is Ray production-ready?

Yes. Used by: OpenAI, Uber, Spotify, AnthropicTesting. Mature ecosystem. Production gotchas exist (debugging distributed systems is hard), but it's the standard for ML workloads.

What's the learning curve?

High. Distributed systems are conceptually hard. Expect 4-8 weeks to build confidence. Start simple, scale incrementally.

Can I use Ray for real-time serving?

Ray Serve enables real-time inference. It's not as optimized as specialized servers (TensorFlow Serving), but it works for most use cases.

How much does Anyscale cost?

Pay-as-you-go for compute. $0.50-5.00/hour per node depending on size. 100-node cluster training for 10 hours: ~$500-5000. Pricing varies by workload and commitment.

Can I use Ray without Anyscale?

Yes. Ray is open-source. Self-host on Kubernetes or your own infra. Anyscale is managed convenience + support.

What are the common failure modes?

Out-of-memory errors (too many workers, not enough memory), network latency (slow inter-node communication), and debugging distributed failures (hard to trace).
