Best 8 Machine Learning Model Deployment Tools That You Need to Know
How we create and deploy trained model APIs in the production environment is governed by many aspects of the machine learning lifecycle. The concept of MLOps has been very beneficial for dealing with complex ML deployment environments.
Implementing solid MLOps can generate big benefits for a company invested in machine learning. Understanding what to employ and execute is an essential part of the puzzle. Learning and adapting to a new tool that simplifies the overall workflow is a whole other thing.
This article lists the best tools used for model deployment. All the essentials to help you scale and manage the machine learning lifecycle, involving serving, monitoring, and managing the API endpoint.

If you want to deploy your trained model as an endpoint, you can do that with TensorFlow Serving.
It lets you create a REST API endpoint that will serve the trained model. TensorFlow Serving is a robust, high-performance system for serving machine learning models.
You can deploy a state of the art machine learning algorithms easily while maintaining the same server architecture with its respective endpoints. It’s powerful enough to serve different types of models and data, along with TensorFlow models.
It was created by Google, and many top companies use it. Serving the model as a centralized model base is a great way to do it. The serving architecture is efficient enough for a large pool of users to access the model at the same time.
If there’s any choking due to a large number of requests, it can be easily maintained using the load balancer. Overall, the system is scalable and maintainable with a high-performance rate.
TensorFlow Serving pros:
- This tool allows easy serving once the deployment models are ready.
- It can initiate batch requests to the same model, so hardware is used efficiently.
- It offers model versioning management as well.
- The tool is easy to use and takes care of model and serving management.
TensorFlow Serving cons:
- There is no way to ensure zero downtime when new models are loaded or old ones are updated.
- Works only with TensorFlow models.
