What does it mean when we describe our AI MODEL as a ‘Product’?

How is that Product used in commercial business IT Systems?
In this lecture, we will cover the fundamental aspects of designing and implementing a robust architecture for AI systems.
Start by getting a solid visualization on what the Architecture of an AI Model is.
The goal is to ensure that your AI product is scalable, maintainable, and efficient.
And most importantly: Serves the business domain which it is operating.
We'll also discuss the Unified Model Engineering Process (UMEP), which integrates various stages of AI development.

1. Definition and Importance of Software Architecture

Software Architecture is the high-level structure of a software system, comprising the software components, their externally visible properties, and the relationships between them.
It serves as a blueprint for both the system and the project, enabling effective project management and ensuring the system meets its requirements.
It encapsulates the understanding of the Subject Matter Experts of how the Business Domain operates.
Qualities of a well foundationed Architecture:
Scalability: Ensures the system can handle growth in users, data, transactions, and other business requirements.
Maintainability: Facilitates easy updates and modifications.
Performance: Optimizes resource use and ensures the system meets performance benchmarks.
Security: Protects data and ensures compliance with regulations.

4. Continuous Integration/Continuous Deployment (CI/CD)

CI/CD is crucial for maintaining the agility and reliability of AI products:
CI (Continuous Integration): Automates the integration of code changes from multiple contributors into a single software project.
CD (Continuous Deployment): Automates the deployment of the integrated code to production environments.
Tools:
CI Tools: Jenkins, Travis CI, CircleCI.
CD Tools: GitLab CI/CD, AWS CodePipeline, Azure DevOps.
Benefits:

Step 3: Data Storage
Store processed data in a NoSQL database like MongoDB.
Step 4: Model Training
Train a natural language processing (NLP) model using PyTorch on GPU clusters.
Step 5: Model Serving
Deploy the trained model using Docker containers and Kubernetes for scalability.
Step 6: Monitoring and Maintenance
Implement Prometheus for monitoring and Grafana for visualization.
CI/CD Pipeline:
Use GitLab CI/CD to automate testing and deployment processes, ensuring continuous integration and delivery.

Conclusion

Understanding and implementing a robust software architecture is vital for the success of AI products. By leveraging modern tools and methodologies like UMEP and CI/CD, you can build scalable, maintainable, and efficient AI systems.
