Best MLOps Tools & Platforms 2022

Machine learning (ML) teaches computers to learn from data without being explicitly programmed. Unfortunately, the rapid expansion and application of ML have made it difficult for organizations to keep up, as they struggle with issues such as labeling data, managing infrastructure, deploying models, and monitoring performance.

This is where MLOps comes in. MLOps is the practice of optimizing the continuous delivery of ML models, and it brings a host of benefits to organizations.

Below we explore the definition of MLOps, its benefits, and how it compares to AIOps. We also look at some of the top MLOps tools and platforms.

What Is MLOps?

MLOps combines machine learning and DevOps to automate, track, pipeline, monitor, and package machine learning models. It began as a set of best practices but slowly morphed into an independent ML lifecycle management approach. As a result, it applies to the entire lifecycle, from integrating data and model building to the deployment of models in a production environment.

MLOps is a special type of ModelOps, according to Gartner. However, MLOps is concerned with operationalizing machine learning models, whereas ModelOps focuses on all sorts of AI models.

Benefits of MLOps

The main benefits of MLOps are:

• Faster time to market: By automating deploying and monitoring models, MLOps enables organizations to release new models more quickly.
• Improved accuracy and efficiency: MLOps helps improve models’ accuracy by tracking and managing the entire model lifecycle. It also enables organizations to identify and fix errors more quickly.
• Greater scalability: MLOps makes it easier to scale up or down the number of machines used for training and inference.
• Enhanced collaboration: MLOps enables different teams (data scientists, engineers, and DevOps) to work together more effectively.

MLOps vs. AIOps: What are the Differences?

AIOps is a newer term coined in response to the growing complexity of IT operations. It refers to the application of artificial intelligence (AI) to IT operations, and it offers several benefits over traditional monitoring tools.

So, what are the key differences between MLOps and AIOps?

• Scope: MLOps is focused specifically on machine learning, whereas AIOps is broader and covers all aspects of IT operations.
• Automation: MLOps is largely automated, whereas AIOps relies on human intervention to make decisions.
• Data processing: MLOps uses pre-processed data for training models, whereas AIOps processes data in real time.
• Decision-making: MLOps relies on historical data to make decisions, whereas AIOps can use real-time data.
• Human intervention: MLOps requires less human intervention than AIOps.

Types of MLOps Tools

MLOps tools are divided into four major categories dealing with:

1. Data management
2. Modeling
3. Operationalization
4. End-to-end MLOps platforms

Data management

• Data Labeling: Large quantities of data, such as text, images, or sound recordings, are labeled using data labeling tools (also known as data annotation, tagging, or classification software). Labeled information is fed into supervised ML algorithms to generate new, unclassified data predictions.
• Data Versioning: Data versioning ensures that different versions of data are managed and tracked effectively. This is important for training and testing models as well as for deploying models into production.

Modeling

• Feature Engineering: Feature engineering is the process of transforming raw data into a form that is more suitable for machine learning algorithms. This can involve, for example, extracting features from data, creating dummy variables, or transforming categorical data into numerical features.
• Experiment Tracking: Experiment tracking enables you to keep track of all the steps involved in a machine learning experiment, from data preparation to model selection to final deployment. This helps to ensure that experiments are reproducible and the same results are obtained every time.
• Hyperparameter Optimization: Hyperparameter optimization is the process of finding the best combination of hyperparameters for an ML algorithm. This is done by running multiple experiments with different combinations of hyperparameters and measuring the performance of each model.

Operationalization

• Model Deployment/Serving: Model deployment puts an ML model into production. This involves packaging the model and its dependencies into a format that can be run on a production system.
• Model Monitoring: Model monitoring is tracking the performance of an ML model in production. This includes measuring accuracy, latency, and throughput and identifying any problems.

End-to-end MLOps platforms

Some tools go through the machine learning lifecycle from end to end. These tools are known as end-to-end MLOps platforms. They provide a single platform for data management, modeling, and operationalization. In addition, they automate the entire machine learning process, from data preparation to model selection to final deployment.
