Microsoft AI-103: Deploying Fine-Tuned Models on Azure

A fine-tuned model is not production-ready when training finishes. It becomes operational only after the team has selected a checkpoint, passed quality and safety evaluation, chosen a supported deployment type, configured access, tested inference behavior, and defined how the deployment will be upgraded or retired. Deployment is the point where a training artifact becomes a service with cost, capacity, and lifecycle responsibilities. Microsoft Foundry currently allows fine-tuned Azure OpenAI models to be deployed for inference after training. Deployment requires appropriate control-plane permissions, and supported deployment types vary by model and…

Microsoft AI-103: Cost Control for Azure AI Apps

Azure AI cost is not one number. A production application can generate charges from model tokens, provisioned throughput, fine-tuned model hosting, search, storage, Application Insights, API Management, functions, databases, and external tools. The only useful cost model is therefore a workload model: what a successful user task invokes, how often it happens, and how that behavior changes under load. Microsoft Foundry currently supports pay-as-you-go model usage, provisioned throughput, fine-tuned model hosting, and gateway-level token controls. Azure Cost Management provides the billing view, while model and application telemetry explain why usage…

Microsoft AI-103: Chunking Strategies for Azure RAG

Chunking determines what a retrieval system is capable of finding. In an Azure RAG application, documents are rarely useful as one large block of text. The retrieval layer needs units that are small enough to match a focused question but large enough to preserve the context that makes the answer meaningful. That balance is why chunking deserves to be designed and evaluated rather than treated as an indexing default. Current Azure AI Search guidance supports several approaches, from fixed text splitting to structure-aware chunking with document layout information. Integrated vectorization…

Microsoft AI-103: Choosing Embeddings on Azure

Embedding choice affects retrieval quality, index size, query latency, re-indexing cost, and the long-term shape of a RAG system. It is easy to treat embeddings as an implementation detail because they sit behind vector search, but the vector dimensions are part of the index schema and the model determines how text is represented. Changing either later can require rebuilding the vector corpus. Azure OpenAI currently supports third-generation embedding models such as text-embedding-3-small and text-embedding-3-large, alongside older options in some services. Azure AI Search can use these models through integrated vectorization…

Microsoft AI-103: Choosing Azure AI Deployment Models

Azure AI deployment choices determine more than where a model runs. They affect where inference data can be processed, how capacity is allocated, whether billing is pay-per-token or reserved, how much latency variation to expect, and whether the workload is suited to real-time or asynchronous processing. Choosing the wrong deployment type can create a compliance or reliability problem even when the model itself is a good fit. Microsoft Foundry currently uses serverless API as the preferred deployment option for a broad set of Foundry Models. Within that option, deployments can…

Microsoft AI-103: Capacity Planning for Azure AI

Capacity planning for Azure AI begins with a simple correction: serverless does not mean unlimited. Model APIs can have tokens-per-minute limits, requests-per-minute limits, concurrency constraints, regional availability, deployment-specific quotas, and capacity that changes by model and SKU. A workload that looks small in request counts can still be large in tokens, while a high-request workload with tiny prompts can hit request limits before token limits. Microsoft Foundry separates standard pay-per-token deployment types from provisioned throughput and batch options. Azure OpenAI quotas are also scoped by factors such as subscription, region,…

Microsoft AI-103: Canary Releases for AI Models

A canary release exposes a new AI version to a deliberately small portion of production traffic before broader rollout. The idea is familiar from ordinary software delivery, but AI adds a second dimension: the endpoint can remain technically healthy while answer quality, safety behavior, tool selection, or retrieval performance gets worse. The canary therefore needs behavioral release criteria as well as infrastructure metrics. Azure Machine Learning managed online endpoints support percentage-based traffic routing between deployments, which makes them a natural fit for canary rollout. For model services where native traffic…

Microsoft AI-103: Building Multi-Agent Workflows on Azure

Multi-agent systems are useful when a problem genuinely benefits from specialized responsibilities, separate tool access, or explicit handoffs. They are not automatically better than a single agent. Every additional agent creates another source of latency, another state boundary, another identity to govern, and another place where the system can misunderstand what should happen next. That tradeoff is especially important in Azure right now because Microsoft’s orchestration stack is changing. The older visual Workflows experience in Microsoft Foundry is scheduled for retirement on December 1, 2026. Microsoft’s current direction for new…

Microsoft AI-103: Blue-Green Releases for AI Endpoints

Blue-green deployment is valuable for AI because a successful health check does not prove that a new version behaves well. An endpoint can return HTTP 200, stay within CPU limits, and still produce worse answers because the model, prompt, preprocessing code, retrieval configuration, or safety policy changed. A release strategy therefore needs to validate both infrastructure and behavior. Azure Machine Learning managed online endpoints provide a clear implementation of blue-green rollout. A single endpoint can contain multiple deployments, route traffic between them, and mirror production traffic to a new deployment…

Microsoft AI-103: Azure AI Search for RAG

Azure AI Search can serve as the retrieval layer for a RAG application, but its value is not simply that it stores vectors. The service combines full-text search, vector search, semantic ranking, filtering, indexing pipelines, and integrated vectorization. Those capabilities matter because enterprise questions rarely behave like clean semantic-similarity demos. They contain product codes, names, dates, exact phrases, ambiguous language, and authorization rules that require more than nearest-neighbor lookup. Microsoft’s current guidance distinguishes classic RAG from newer agentic retrieval patterns. Classic RAG gives the application direct control over query construction…

Microsoft AI-103: Azure AI Foundry Model Selection

Model selection in Azure should begin with the workload, not the catalog. A model can score well on a public benchmark and still be a poor production fit because it is unavailable in the required deployment type, too slow for the interaction pattern, too expensive at expected token volumes, weak on the organization’s own data, or incompatible with a required tool or modality. Microsoft Foundry gives teams access to models from Microsoft, Azure OpenAI, and multiple partner and community providers. That breadth is valuable, but it makes a disciplined selection…

Microsoft AI-103: Azure AI Content Safety in Practice

AI safety controls are most useful when a team knows exactly which failure they are meant to catch. A generic instruction to “turn on content safety” can hide several different problems: harmful user input, prompt injection, unsafe output, unsupported claims, protected material, risky tool use, or a business-specific policy violation. Each problem appears at a different point in the application and needs a different response. Azure AI Content Safety provides a set of guardrails rather than one universal filter. The current service includes text and image harm analysis, Prompt Shields,…

Microsoft AI-103: Agent Identity in Azure AI Foundry

Agent identity becomes an architecture problem as soon as an AI system can do more than generate text. An agent that calls an API, reads a knowledge store, creates a ticket, queries a database, or invokes another agent needs a principal that downstream systems can authenticate and authorize. If every agent simply inherits the same broad application identity, the system may work, but it becomes difficult to answer a basic security question: which agent was actually allowed to do what? Microsoft’s current documentation uses the Microsoft Foundry name for the…

ServiceNow Platform Engineering

ServiceNow Platform Engineering is the discipline of designing the Now Platform so data, configuration, services, integrations, automation, security, and operations remain maintainable as the enterprise grows. The platform is not only a collection of workflows. It is a shared data and execution environment whose value depends on stable models, trusted configuration data, clear ownership, reusable standards, and change practices that let many teams build without fragmenting the platform. For the Data Foundations cluster, the Configuration Management Database is one of the most important shared platform services. A trustworthy CMDB needs…

Security Governance & Assurance

Security Governance & Assurance is the management layer that turns security from a collection of controls into an accountable enterprise system. Governance defines authority, strategy, risk boundaries, ownership, policy, and investment. Assurance tests whether those decisions and controls are actually operating as intended. The two belong together because management intent without evidence becomes ceremony, while evidence without decision rights becomes reporting with no owner. This authority cluster spans the management themes behind ISACA certifications, the CISM certification, later CISSP leadership topics, and IT audit work. The durable questions are broader…
