Enterprise AI Infrastructure Platform Capabilities

The capabilities of the enterprise AI infrastructure platform are described below:

Software Engineering Practices for AI

Advanced machine learning practices increasingly integrate software engineering disciplines like Test-Driven Development (TDD), continuous integration, rollback and recovery, and change control. Simply developing a Jupyter notebook and handing it off to a team for operationalization is no longer sufficient. Enterprise AI strategies should adopt end-to-end DevOps practices similar to those in high-grade engineering organizations, supporting various models and data types while remaining flexible for innovations in machine learning and deep learning.

Challenges of Storage and Disk/IO

Data parallel computing workloads require parallel storage. The primary challenges in running Deep Learning Models—whether in the cloud or on-premises—include bottlenecks from the edge to the core to the cloud, such as:

• Slow data ingestion
• Outdated on-premises technology
• Virtualized storage bottlenecks in the cloud

Even when deploying deep learning in the cloud for agility, these bottlenecks can persist. Configuring Kubernetes for co-location can help mitigate these issues, providing the flexibility needed for effective deep-learning pipelines.

Health Checks & Resiliency

Kubernetes offers features that enhance application resiliency by managing failovers, ensuring that on-prem environments can achieve cloud-like resilience.

Framework Interoperability

To facilitate model framework, language, and library agnosticism, Facebook and Microsoft initiated a community project supported by AWS. This interoperability allows a single machine-learning application to deploy across various platforms. Frameworks like ONNX and MLeap provide standardized formats for model artefacts, optimizing them for efficient performance on serverless platforms built on Kubernetes.

3. Containerization: Package the model and its dependencies into a container (e.g., using Docker). This ensures consistency across different environments and simplifies deployment.

4. Deploy the Containerized Model: Set up the necessary infrastructure in your chosen environment (e.g., Kubernetes cluster) to host the containerized model. Configure networking and security settings to ensure proper access to resources.

5. Monitor and Maintain: After deployment, continuously monitor the model's performance to ensure it meets operational standards. Implement logging and alerting mechanisms to track usage and identify any issues promptly.

Build Your Own DataOps Platform using Kubernetes

With Enterprises becoming jealous of data and security paramount, Becoming an AI-powered enterprise requires a custom-made Data Platform. Every enterprise has its natural data and needs. The number of teams involved makes it challenging to have security and compliance in place while, at the same time, giving organizations the freedom to run experiments and discover data. An Enterprise Data Strategy should elaborate on how Data will be securely shared across various teams.

Big Data Applications are evolving and have become more friendly to Kubernetes. With the rise of Kubernetes Operators, running complex stateful workloads on Kubernetes has become a much simpler task. Data Governance is required, and how it benefits them and an organization.

Data Lineage for AI Platform

Capturing all events across the data and AI platform comprises events from infrastructure to application. The Data Lineage Service should be capable of capturing events from ETL Jobs, Querying Engines, and Data Processing Jobs. There should also be Data Lineage as a Service, which can be integrated by any other services where there is a need to incorporate Data Lineage. ELK Stack and Prometheus can provide Lineage for the Kubernetes Cluster and the Workloads Happening on top of it.

Data Catalog with Version Control

With MultiCloud and Cloud Bursting in Mind, The Data Stored should have version control. The version control for data should be as reasonable as the version control for Software code. The Data Version Control should be built on top of Object Storage, which can be integrated with Existing Services. Minio is a service that can be combined with S3 and provide the same APIs. For machine learning model data, DVC allows the storage and versioning of source data files, ML models, directories, and intermediate results with Git without checking the file contents in Git. Meta Cat should be integrated with the Data on Premises and External Sources.
