Introduction
In the realm of technology, the goal of operations is to ensure the continuous and efficient functioning of production systems. As Machine Learning (ML) gains popularity and ML models are deployed in production environments, the concept of MLOps emerges as an essential practice. With the rise of the Internet of Things (IoT) and AI-enabled edge devices, a parallel framework, Edge MLOps, also becomes necessary. The proliferation of smart devices at the edge introduces unique challenges, such as latency, connectivity issues, and the need for real-time processing. Consequently, Edge MLOps focuses on extending the principles of MLOps to these edge environments, ensuring robust and efficient operation with minimal human intervention.
In essence, Edge MLOps seeks to create a resilient and scalable ecosystem where machine learning models can thrive, even at the outermost peripherals of a network. By incorporating automation and reducing the need for direct human involvement, Edge MLOps facilitates efficient data management and models continuous improvement of sophisticated AI systems on edge devices.
Getting MLOps right from the start is crucial for ensuring the scalability, reliability, and efficiency of machine learning operations as they grow. A robust automated MLOps pipeline enables seamless continuous model improvement and prevents accuracy degradation caused by data drift—a challenge inherent to machine learning systems that differs from traditional software systems.
There are numerous MLOps articles and blogs available online. For instance, the Neptune MLOps blog offers an exhaustive list and comprehensive summary of numerous MLOps platforms. However, very few sources address the entire end-to-end architecture, data flow, and all components of MLOps. From the Neptune blog, it’s clear that most MLOps platforms cover only limited capabilities. Hence, we have created this blog to detail the architecture, challenges, and gaps of MLOps, as well as our criteria for effective Edge MLOps solutions.
Edge MLOps Architecture
Diagram: Edge MLOps Architecture
The above diagram illustrates Edge MLOps components and architecture. The system is broken into two main areas: Field Management and Model Continuous Improvement. Here’s a detailed explanation.
2.1 Field Management
Edge Device:
- Edge devices are deployed in the field to perform real-time processing with the deployed model and collect data for model monitoring and improvement.
Device Management:
- Monitors the status of edge devices (e.g., health, performance).
- Sends edge model updates, upgrades, and patches to maintain the devices’ functionality and security.
- Receives improved edge model and deploys it to the edge devices.
2.2 Model Continuous Improvement
Data Collection and Storage:
- Collects and separates detected positive and negative data from the edge devices.
- Stores opt-in data.
Observability Model Inference:
- Infer collected data with larger Observability Models and compare with Edge Model detection output to identify potential false negative data and model drift.
Data Annotation:
- Human annotators review and confirm false positive and false negative data.
Data Augmentation, Synthesis and Curation:
- Processes the human-confirmed false positive and negative data.
- Performs data augmentation and synthesis to increase data variation.
- Curates the dataset to fine-tune and improve the model.
Training and Finetuning:
- Uses the fine-tuned datasets to train and finetune the model.
Deployment:
- Compress, prune, and quantize the improved model for deployment on edge devices.
Edge MLOps Challenges and Platform Comparison
If things fall apart due to faulty MLOps, there is often a substantial dollar cost associated with rectifying issues such as model failures and system downtimes. Time and productivity are also severely impacted. Furthermore, a faulty MLOps framework can derail an entire implementation by causing missed business opportunities, degraded model performance, and lost stakeholder confidence. In extreme cases, critical decision-making systems reliant on machine learning might produce inaccurate or biased outcomes, leading to further financial and reputational damage.
Implementing an Edge MLOps practice faces several critical challenges, including:
- Limited Features in Commercial-off-the-shelf MLOps Platforms: Many commercial off-the-shelf MLOps platforms focus on a limited scope, providing only a restricted set of features, which makes it challenging for them to support all essential components required for an end-to-end solution. The most significant gaps of the Commercial-off-the-shelf MLOps platforms include the lack of the Observability Model component, inadequate integration of all components, and insufficient device management capabilities.
- Specialized Expertise Required: Building infrastructure and components, and integrating the necessary pipeline for these platforms demands extensive technical skill sets, expertise, and significant effort.

Table: Comparison of Representative MLOps Platforms
The above table is a comparative analysis of several representative MLOps platforms based on the various functionalities they offer. There are more types of MLOps platforms. Some types (e.g. Labelbox, Scale AI) focus on data annotation. Some types (e.g. Weights & Biases, MLFlow) focus on experiment monitoring and versioning. The SiMa.ai ONE Platform for Edge AI provides comprehensive end-to-end MLOps capabilities, especially for critical Integration, Observability Model Inference, and Device Management.
Edge MLOps Reality and Gaps
In one sense, computer and information technology revolves around automation and reducing manual labor. Yet, we’ve added layers and abstractions to conceal the underlying complexity, from chip to board, operating system, SDK, API, application, and SaaS. Currently, the operations of most ML systems remain highly manual, except for a few tech giants who need to manage numerous models or have the luxury to invest significantly to integrate, automate and optimize these pipelines. Current common practices involve building and integrating MLOps pipelines using tools like Kubernetes, Airflow, Argo Workflows, Kubeflow, etc. These tools require specialized data and software engineering skills. Therefore, there are significant gaps in the industry for enabling most companies, which may lack software engineering expertise, to swiftly implement MLOps and newer Edge MLOps.
SiMa.ai addresses these gaps by integrating all end-to-end Edge MLOps capabilities, hiding the MLOps complexity, and making it as simple as possible, thus filling the industry’s need for accessible, efficient solutions, especially for companies with limited software engineering capabilities.
