Difference Between MLOps vs. Data Engineering

What is Data Engineering?

The practice of designing large-scale data collection, storage, and analysis systems is known as data engineering. It has applications in practically every industry and covers a wide variety of subjects. Massive amounts of data can be collected by organizations, but they need the right individuals and tools to make sure that it is extremely valuable by the time it reaches data analysts and scientists.

Working as a data engineer may provide you with the chance to actually change the world in a world where we'll be producing 463 exabytes every day by 2025 and making the data scientists' life easier. That is one byte followed by 18 zeros of data. In addition, machine learning and deep learning can prosper with data engineers processing and directing the data.

What is MLOps Engineering?

You must install machine learning models as an MLOps engineer and make sure they are operational in production. Because you don't have to create the models yourself, more than machine learning expertise is required for this position. To put the model into use, you must comprehend the underlying machine learning algorithm.

The data science team will create the machine learning model, but you may need to modify some of their deployment-related functions. Since they cannot handle the large amounts of data that enter the system in real-time, most models created by data science teams could be more practical for production. You will have to incorporate the machine learning model into the organization's current data infrastructure as an MLOps engineer. Additionally, it would be best if you focused on optimization so that the model can manage enormous amounts of data in a real-world setting.

Production systems must manage the constant data that enters the server daily. The model must scale as more traffic enters the system to produce forecasts effectively. As a result, the MLOps engineer may occasionally need to modify the model and add improvements without affecting system performance.

Responsibilities of a Data Engineer:

Alongside data scientists, data engineers operate as part of an analytics team frequently. The data scientists run queries and algorithms for applications like predictive analytics, machine learning, and data mining using the data that the engineers provide in usable formats. For business executives, analysts, and end users to examine the data and use the findings to improve business operations, data engineers also provide aggregated data.

Both structured and unstructured data are dealt with by data engineers. Information that can be arranged into a prepared repository, such as a database, is called structured data. Text, photos, audio, and video files are examples of unstructured data that don't follow traditional data models. To handle both forms of data, data engineers need to be familiar with various approaches to data architecture and applications. A range of big data tools, such as open-source data input and processing frameworks, are also part of the data engineer's arsenal.

Responsibilities of an MLOps Engineer:

A set of methods for installing and maintaining machine learning models in the field is referred to as MLOps. MLOps is everything that occurs after the model is built. Once a model has been trained and assessed, it is prepared for usage. Based on recently entered user data, it can then generate predictions.

Expect the following differences between the two roles:

  • Data scientists typically use Jupyter Notebooks or comparable tools for their work or development.
  • Data scientists are typically more focused on research compared to
  • MLOps concentrate on producing code and programming.
  • MLOps work with AWS/EC2, Google Cloud, or Kubeflow in addition to DevOp technologies like CircleCi and Docker.
  • Usually, MLOps concentrate more on OOP.
  • Data scientists must be familiar with how the actual machine learning algorithm functions (e.g., gradient descent, regularizations, parameter tuning, etc.)
  • Data scientists put a lot of emphasis on selecting and developing the method (e.g., is it supervised, unsupervised, regression-based, classification-based, etc.)
  • Education/schooling differs. More undergrad institutions offer Data Science Bachelor's degrees, typically a Master's in Data Science for Data Scientists and a Software Engineering Bachelor's for MLOps Engineers.
  • Additionally, it helps if Data Scientists and MLOps focus on Software Engineering and Machine Learning through certifications or other shorter training experiences so that both jobs are more well-rounded and can work more effectively together.

Overview of the Data Engineering Process:

Data engineering is an ability that is in higher demand. It is because the system that unifies data is created by data engineers, who can also guide you through it. Data engineers carry out a wide range of duties, such as:

  • Acquisition: It entails locating the many data sets scattered throughout the organization.
  • Cleaning: Recognizing and correcting any data errors
  • Conversion: Assigning a consistent format to all the data
  • Disambiguation: Interpreting information that can be used in several ways.
  • Deduplication: Eliminating duplicate copies of data

Data can then be kept in a central repository, like a data lake or data lakehouse, after this is finished. Subsets of data may also be copied and moved into a data warehouse by data engineers.

Data engineers are essential to the planning, running, and maintaining of the increasingly complex environments that underpin contemporary data analytics. In the past, data engineers have painstakingly created the schemas of data warehouses, creating table structures and indexes that can process queries quickly to guarantee appropriate performance. Data engineers, with the rise of data lakes, have more data to manage and distribute to downstream data consumers for analytics. Unfortunately, data engineers must work with unstructured and poorly formatted data stored in data lakes before the business can benefit from it.

Overview of the MLOps Engineering Process:

The four phases that comprise the data science lifecycle give a quick overview of the entire process and point out the areas on which various team members should concentrate.

  • Manage: The Manage stage focuses on comprehending the project's goals and requirements and setting work priorities. To scope the project, evaluate value, estimate costs, plan a solution, generate mock deliverables, create targets, agree on a timeframe, and establish validation and approval gates, data scientists collaborate with the business, end users, leadership, and data experts. They document this effort for the benefit of upcoming data scientists and auditors alike.
  • Develop: Data scientists construct and evaluate multiple models using a variety of modeling methodologies during the Develop stage. Data scientists build a model and use algorithms and data to test it. They might rely on the data analysts or receive their help. Data engineers provide clean data as assistance. By providing the IT infrastructure needed for data scientists to work, infrastructure engineers help. When data scientists require assistance comprehending intricate linkages found in the data, they consult with data experts.
  • Deploy: Data scientists construct and evaluate multiple models using a range of modeling methodologies during the deployment step. Finally, data scientists transfer the tested model to infrastructure and DevOps engineers in a production setting. The software developer assumes control if the model needs to be rewritten in another language.
  • Monitor: Organizations check that the model provides the anticipated business value and performance during the Monitor stage, which is the operational phase of the lifecycle. Engineers typically keep an eye on the model, bringing in data scientists as needed if issues develop. The data scientists troubleshoot the model if it is acting differently than planned. If there are issues with the data pipeline, the data engineers help. In the following development phase, both use the resources and knowledge gained thus far.


Data Engineers are critical to any business's digital transformation. Inside every business, data engineers create the framework that enables data scientists to perform at their peak levels. Their work creates dependable and secure cloud solutions for businesses to see and modify their data easily. Businesses need internal people to compete globally that can analyze the enormous amounts of data required to become an AI-driven enterprise.

A few years ago, we were processing a tolerable amount of data because there weren't many models, and we were operating on a limited scale. We are now incorporating decision automation into a wide variety of applications, which is turning out to be very different from the past. However, when it comes to creating and deploying things, ML-based systems might present technical problems.

A data-driven business now uses a variety of teams, including the product team, data engineering, data science, and IT/DevOps, to design and deploy ML models.

We have accelerated system development and deployment by applying this new machine learning engineering culture (MLOps), improving communication between data scientists and dev ops, and streamlining workflow.
