What is MLOps?
You can encounter a wide variety of MLOps definitions on the web. At ITRex, we define MLOps as follows.
Generally, the primary objective of MLOps is to streamline the process of deploying, maintaining, and tracking machine learning models in production environments by bridging the gap between data scientists, ML developers, and operations teams. As the statement above suggests, MLOps is a collaborative approach that amalgamates machine learning, data science, and software engineering into one cohesive practice.
More fundamentally, MLOps applies to the entire machine learning lifecycle—data collection, exploratory data analysis, data preparation, feature engineering, model training and development, model deployment, model monitoring, and model retraining. It offers a structured framework to support the seamless transition of machine learning models from the experimental to the live environment.
Key components of MLOps
What is MLOps in terms of its key elements? While there may be more, the following are the most crucial components of MLOps that work together to streamline the end-to-end process of deploying and maintaining machine learning models, ensuring reliability, scalability, and efficiency:
-
Collaboration
As we’ve mentioned previously, with MLOps, teams can collaborate more effectively and quickly to pool their knowledge and expertise to construct machine learning models that are faster, more scalable, and more broadly applicable. In contrast, if we examine the traditional scenario of collaborating on ML projects, we observe a disjointed and unrelated collection of people with entirely different sets of skills. In this way, MLOps offers a solid framework and a set of tools and techniques to facilitate effective collaboration across data scientists, ML engineers, and operations teams.
-
Automation
The goal of MLOps is to automate every step of the ML workflow to ensure repeatability, consistency, and scalability. Changes to data and model training code, calendar events, messages, and monitoring events can all act as triggers for automated model training and deployment. A crucial component of MLOps is automated reproducibility, which ensures the accuracy, traceability, and stability of machine learning solutions across time.
-
CI/CD
MLOps involves using continuous integration and deployment (CI/CD) techniques to help facilitate collaboration between data scientists and machine learning developers and thus speed up the creation and production of ML models.
-
Version control
A large number of events can result in changes to the data, code base, or an anomaly in a machine learning model. There is a code review phase for every ML training code or model specification; each is versioned. Version control is a crucial aspect of MLOps used to track and save different versions of the model. This makes it easy to reproduce results and revert to a previous version in case any issue arises.
-
Real-time model monitoring
The job is far from done once a machine learning model is put into use. MLOps allows organizations to continuously track and assess the performance and behavior of machine learning models in production environments. Real-time model monitoring helps swiftly identify and address issues, thereby ensuring the model remains effective and accurate over time.
-
Scalability
There are several ways MLOps contributes to scalability. One of the ways is through the automation of ML pipelines. This automation reduces the need for manual intervention, allowing for quicker and more reliable scaling of ML operations. Another way MLOps ensures scalability is through continuous integration/continuous deployment techniques. By putting in place CI/CD pipelines, new code and models can be automatically tested and released, cutting down on time to market and facilitating the quick scaling of machine learning solutions.
-
Compliance
MLOps ensures that machine learning models are created and deployed in an open, auditable manner and adhere to rigorous standards. Furthermore, MLOps can aid in improving model control, guaranteeing proper and ethical conduct, and preventing bias and hallucinations.
Why do we need MLOps?
The broad answer to the question “What is MLOps and why do we need it?” can be outlined as follows. Taking machine learning models to production is no mean feat. Machine learning lifecycle consists of many complex phases and requires cross-functional team collaboration. Maintaining synchronization and coordination between all of these processes is a time and resource-consuming task. Thus, we need some standardized practices that could guide and streamline all processes across the ML lifecycle, remove friction from ML lifecycle management, and accelerate release velocity to translate an ML initiative into ROI.
To explain this further, let’s explore the main reasons why organizations need MLOps.
1. ML models perform poorly in production environments
There are a number of reasons for ML models to underperform in production environments. Failed productionized ML models mostly arise from data dismatch, model complexity, overfitting, concept drift, and operational issues. Operational issues relate to the technical difficulties of implementing and running a model in a dynamic environment, including compatibility, latency, scalability, reliability, security, and compliance. When a model has to interact with other systems, components, and users as well as manage changeable workloads, requests, and failures, it might not function as well in a real-world production environment as it would in a regulated and isolated one.
Addressing these challenges often requires a combination of careful model selection, reliable training procedures, continuous monitoring, and close collaboration between data scientists, ML engineers, and domain experts. MLOps is the newest field meant to prevent and tackle these problems with strict, automated monitoring throughout the entire pipeline, from collecting, processing, and cleaning the data to model training, generating predictions, assessing model performance, transferring the model output to other systems, and logging model and data versions.
2. Limited collaboration between data science and IT teams
The traditional way of deploying ML models into production is a disjointed process. After a model has been created by data scientists, it is passed on to the operations team for deployment. This transfer frequently leads to bottlenecks and challenges because of complex algorithms or disparities in the settings, tools, and goals.
MLOps promotes collaboration that weaves together the expertise of siloed teams and thus helps to lessen the frequency and severity of these kinds of problems. This improves the efficiency of machine learning model development, testing, monitoring, and deployment.
3. Failure to scale ML solutions beyond PoC
The desire to extract business insights from massive amounts of data is constantly increasing. This has led to the requirement for machine learning systems to be adaptable to changing data types, scale with rising data volumes, and reliably produce accurate results even in the face of uncertainties associated with live data.
Many organizations have a hard time utilizing machine learning in its more advanced versions or applying it more broadly. According to the McKinsey survey, only about 15% of respondents have successfully operationalized ML at scale. Another survey by Gartner found that only 53% of AI initiatives successfully transition from prototype to production. This mostly relates to the inability of ML solutions to be applied in a commercial environment with rapidly scaling data.
This mainly arises from different teams working on an ML project in isolation—siloed initiatives are hard to scale beyond a proof of concept, and crucial operational elements are often disregarded. MLOps serves as a standardized set of tools, culture, and best practices that involve a number of defined and repeatable actions to address all ML lifecycle components and ensure a reliable, quick, and continuous production of ML models at scale.
4. The abundance of repetitive tasks in the ML lifecycle
The MLOps approach helps shorten the ML development lifecycle and boost model stability by automating repetitive processes in the workflows of data science and engineering teams. In addition, by eliminating the need to repeatedly complete the same steps in the ML development lifecycle, automation allows different teams to become more strategic and agile in ML model management and focus on more important business problems.
5. Faster time-to-market and cost reductions
A standard machine learning pipeline consists of multiple phases, including data collection, pre-processing, training models, assessment, and deployment. Conventional manual approaches frequently result in inefficiencies at each stage—they are time-consuming and labor-intensive. Fragmented processes and communication gaps impede smooth ML model deployment. Problems with version control can cause confusion and wasted effort. These inefficiencies lead to faulty models, sluggish development cycles, excessive costs, and eventually lost commercial prospects.
Lower operating expenses and quicker time-to-market are two main benefits of automating model creation and deployment with MLOps. The goal of the newly-emerging area of MLOps is to give the ML lifecycle speed and agility. With MLOps, ML development cycles become shorter, and deployment velocity rises. Effective resource management, in turn, leads to significant cost reductions and faster time-to-value.
