MLOps, or DevOps for machine learning, is a practice that aims to bring the collaboration and automation practices of DevOps to the development and deployment of machine learning models. It aims to improve the speed and reliability of model development and deployment, as well as to make the process more reproducible and maintainable. By following these steps and using tools and practices from the DevOps philosophy, organizations can improve the speed and reliability of their machine learning model development and deployment processes, and better manage the complexity and scale of their machine learning systems. By testing and validating the model continuously throughout the development process, data scientists can ensure that the model is accurate, reliable, and effective when it is deployed to production.

The use of Machine Leaning (ML) has increased substantially in enterprise data analytics scenarios to extract valuable insights from the business data. Hence, it is very important to have an ecosystem to build, test, deploy, and maintain the enterprise grade machine learning models in production environments. The ML model development involves data acquisition from multiple trusted sources, data processing to make suitable for building the model, choose algorithm to build the model, build model, compute performance metrics and choose best performing model. The model maintenance plays critical role once the model is deployed into production. The maintenance of machine learning model includes keeping the model up to date and relevant in tune with the source data changes as there is a risk of model becoming outdated in course of time.

Data scientists often develop machine learning models to solve a variety of problems in the industry and academy but not without facing several challenges in terms of Model Development. The problems regarding Machine Learning Development involves the fact that such professionals do not realize that they usually perform ad-hoc practices that could be improved by the adoption of activities presented in the Software Engineering Development Lifecycle. Of course, since machine learning systems are different from traditional Software systems, some differences in their respective development processes are to be expected. In this context, this paper is an effort to investigate the challenges and practices that emerge during the development of ML models from the software engineering perspective by focusing on understanding how software developers could benefit from applying or adapting the traditional software engineering process to the Machine Learning workflow.

Over the past two decades, the biggest evolution of Artificial Intelligence has been the maturation of deep learning as an approach for machine learning, the expansion of big data and the knowledge of how to effectively manage big data systems, and affordable and accessible compute power that can handle some of the most challenging machine learning model development. Today's data scientists and machine learning engineers now have a wide range of choices for how they build models to address the various patterns of AI for their particular needs. However, The diversity in options is actually part of the challenge for those looking to build machine learning models. There are just too many choices. This, compounded by the fact that there are different ways you can go about developing a machine learning model, is the issue that many AI software vendors do a particularly poor job of explaining what their products actually do.

If you intend to take the certification, this will be a good starting point. If you don't, this will help you develop the basic know-how needed to succeed in a rapidly evolving Machine Learning ecosystem. This is not a certification study guide. This article's objective is to provide a simple explanation of complex ideas and give a broad view of the subject matter. The outline mimics the GCP Professional Machine Learning Engineer certification guide.
