What is Cloud-Native AI?

Cloud-Native AI refers to building and deploying artificial intelligence applications and workloads using cloud-native technology principles. This includes leveraging microservices, containerization, declarative APIs, and continuous integration/continuous deployment (CI/CD) among other cloud-native technologies to enhance AI applications’ scalability, reusability, and operability.

The following diagram illustrates the architecture of Cloud-Native AI, redrawn based on the whitepaper.

Relationship between Cloud-Native AI and Cloud-Native Technologies

Cloud-native technologies provide a flexible, scalable platform that makes the development and operation of AI applications more efficient. Through containerization and microservices architecture, developers can iterate and deploy AI models quickly while ensuring high availability and scalability of the system. Kuuch as resource scheduling, automatic scaling, and service discovery.

The whitepaper provides two examples to illustrate the relationship between Cloud-Native AI and cloud-native technologies, namely running AI on cloud-native infrastructure:

• Hugging Face Collaborates with Microsoft to launch Hugging Face Model Catalog on Azure²
• OpenAI Scaling Kubernetes to 7,500 nodes³

Challenges of Cloud-Native AI

Despite providing a solid foundation for AI applications, there are still challenges when integrating AI workloads with cloud-native platforms. These challenges include data preparation complexity, model training resource requirements, and maintaining model security and isolation in multi-tenant environments. Additionally, resource management and scheduling in cloud-native environments are crucial for large-scale AI applications and need further optimization to support efficient model training and inference.

Development Path of Cloud-Native AI

The whitepaper proposes several development paths for Cloud-Native AI, including improving resource scheduling algorithms to better support AI workloads, developing new service mesh technologies to enhance the performance and security of AI applications, and promoting innovation and standardization of Cloud-Native AI technology through open-source projects and community collaboration.

Cloud-Native AI Technology Landscape

Cloud-Native AI involves various technologies, ranging from containers and microservices to service mesh and serverless computing. Kubernetes plays a central role in deploying and managing AI applications, while service mesh technologies such as Istio and Envoy provide robust traffic management and security features. Additionally, monitoring tools like Prometheus and Grafana are crucial for maintaining the performance and reliability of AI applications.
