How do you know which one is best for you when there are so many choices?

We'll talk about the pros and cons of the top 9 model serving platforms in this post so you can make an informed choice. 

By the end, you'll know which platform fits your needs the best and be ready to take the next step toward a smoother model deployment. Keep reading to find the perfect solution for your use case!

These platforms allow users to deploy trained machine-learning models and instantly make predictions based on fresh data. They offer an interface via which data can be sent to the model, processed, and returned as predictions or outcomes.

Model serving platforms typically offer the following features:

  • Scalability: The platform must be able to handle many requests at once and adjust its capacity in response to demand.
  • Performance: With low latency and high throughput, the platform should be able to produce predictions quickly and effectively.
  • Security: The platform must ensure the model and data are protected from unauthorized access and secure.
  • Monitoring: The platform should include monitoring and logging features to track the model's performance and identify any issues or anomalies.
  • Integration: The platform should provide APIs for accessing the model and be able to integrate with other computer programs.
  • Versioning: The platform should provide model versioning, making deploying new versions simple and rolling out old ones as needed.

Model serving platforms are useful for a variety of tasks, including fraud detection, recommendation systems, natural language processing, picture identification, and many other things.

TensorFlow Serving, Amazon SageMaker, Google Cloud AI Platform, and Microsoft Azure Machine Learning are well-known examples of model serving platforms.
