What is Model Serving Infrastructure?
Model Serving Infrastructure comprises the systems, platforms, and tools for deploying, hosting, and managing machine learning models in production. It includes model servers, load balancers, auto-scaling, monitoring, API gateways, and resource orchestration to ensure reliable, scalable, and cost-effective inference.
This glossary term is currently being developed. Detailed content covering implementation strategies, best practices, and operational considerations will be added soon. For immediate assistance with AI implementation and operations, please contact Pertama Partners for advisory services.
Model serving infrastructure directly determines whether your ML models create business value or sit unused. Poor serving infrastructure causes latency spikes, dropped predictions, and unreliable availability that erode user trust. Companies investing properly in serving infrastructure see 3-5x higher ML adoption rates across their organization because internal consumers trust the predictions will be available when needed. The cost of serving infrastructure is typically 10-20% of total ML platform spend but enables 80% of the business value.
- Container orchestration (Kubernetes) for model deployment
- GPU/CPU resource allocation and optimization
- API management and request routing
- Integration with monitoring and logging systems
- Start with managed serving services to reduce operational burden, and only self-host when you've outgrown them or have specific requirements they can't meet
- Design serving infrastructure for the traffic volume you'll need in 12 months, not just current demand, to avoid costly re-architecture
- Start with managed serving services to reduce operational burden, and only self-host when you've outgrown them or have specific requirements they can't meet

More Questions
Success metrics include system uptime, model performance stability, deployment velocity, and operational cost efficiency.
Start with a managed service like AWS SageMaker Endpoints, Google Vertex AI, or Azure ML. These handle auto-scaling, load balancing, and monitoring out of the box. For 10,000-100,000 daily predictions, budget $200-$1,000/month. You need a model registry for versioning, a deployment pipeline for updates, and monitoring for latency and error rates. Avoid building custom serving infrastructure until managed services become limiting, which typically happens above 1 million daily predictions.
Consider self-hosting when managed service costs exceed $5,000/month, you need sub-10ms latency that managed services can't deliver, you have strict data residency requirements, or you need custom preprocessing that doesn't fit managed service constraints. Self-hosting with tools like TensorFlow Serving, Triton, or BentoML gives more control but requires 0.5-1 dedicated engineer for operations. Most companies under 50 employees should stick with managed services.
Deploy across multiple availability zones with health checks and automatic failover. Maintain at least 2 serving instances with load balancing. Implement circuit breakers to route traffic away from unhealthy instances. Keep the previous model version warm for instant rollback. Cache frequent predictions to reduce load on model instances. Target 99.9% availability (8.7 hours downtime per year) as a starting point and invest in higher availability only if business requirements justify the cost.

A TPU, or Tensor Processing Unit, is a custom-designed chip built by Google specifically to accelerate machine learning and AI workloads, offering high performance and cost efficiency for training and running large-scale AI models, particularly within the Google Cloud ecosystem.
A model registry is a centralised repository for storing, versioning, and managing machine learning models throughout their lifecycle, providing a single source of truth that tracks which models are in development, testing, and production across an organisation.
A feature pipeline is an automated system that transforms raw data from various sources into clean, structured features that machine learning models can use for training and prediction, ensuring consistent and reliable data preparation across development and production environments.
An AI gateway is an infrastructure layer that sits between applications and AI models, managing routing, authentication, rate limiting, cost tracking, and failover to provide centralised control and visibility over all AI model interactions across an organisation.
Model versioning is the practice of systematically tracking and managing different iterations of AI models throughout their lifecycle, recording changes to training data, parameters, code, and performance metrics so teams can compare, reproduce, and roll back to any previous version.
