Microsoft Azure

Azure OpenAI Service Solutions

Design, build and operate generative AI applications on Azure OpenAI in Microsoft Foundry, grounded in your data, protected by your Azure security controls and measured against real business outcomes.

Enterprise Generative AI on Azure OpenAI

Azure OpenAI gives organizations access to OpenAI’s GPT and reasoning models, embeddings, image and audio models through Microsoft Azure, with enterprise features such as Microsoft Entra ID authentication, private networking, regional and data zone deployment options and built-in content filtering. Today it is delivered as part of Microsoft Foundry, formerly Azure AI Foundry, alongside other model families, agent tooling and evaluation features.

Hanoi Technology builds production applications on this platform: knowledge assistants grounded with Azure AI Search, document processing pipelines, copilots inside line-of-business systems and agents that call your APIs. We start with an evaluation set, choose models on measured quality and cost, and operate solutions with monitoring for accuracy, latency and spend.

The Challenge

What Makes Azure OpenAI Projects Hard

Access to strong models is easy; production-grade applications are not.

Grounding and Hallucinations

Without well-designed retrieval over your own content, models answer fluently but incorrectly, and users quickly stop trusting the assistant.

Security and Data Boundaries

Security teams must confirm where data is processed, how prompts are logged, who can access which documents and how the solution fits existing network controls.

Model and Deployment Choices

Many models, versions and deployment types such as Global Standard, Data Zone and provisioned throughput affect quality, latency, data residency and cost.

Quotas, Cost and Scale

Token usage grows with long contexts, retrieval and agent loops, and rate limits can throttle applications that were not designed for them.

Business Value

Why Build on Azure OpenAI

Enterprise Security Model

Entra ID authentication, managed identities, private endpoints and role-based access let generative AI follow the same controls as your other Azure workloads.

Grounded, Permission-Aware Answers

Azure AI Search with hybrid and vector retrieval connects models to SharePoint, Blob storage, databases and OneLake while respecting document permissions.

Responsible AI Controls

Content filters, prompt shields, groundedness detection and evaluation tools in Foundry help detect harmful content, jailbreak attempts and unsupported answers.

Choice of Models

Foundry offers Azure OpenAI models alongside other model families, so each task can use the model that best fits its quality, speed and cost needs.

Agents Integrated with Your Systems

Foundry Agent Service and tool calling let agents query data, call APIs and trigger workflows with logging and approval steps.

Integration with the Microsoft Ecosystem

Solutions connect with Microsoft 365, Teams, Power Platform, Fabric and Dynamics 365 where your users already work.

Engineering Discipline Turns Models into Products

Model capability improves every few months. What separates useful applications from impressive demos is evaluation, retrieval quality, security design and cost control. We treat each of these as engineering work with measurable criteria.

Azure OpenAI FAQ

Is our data used to train OpenAI models?

According to Microsoft’s published data, privacy and security documentation for Azure OpenAI, prompts and completions are not used to train OpenAI’s foundation models and are not made available to OpenAI. Data is processed within Microsoft’s Azure environment under Microsoft’s product terms. Abuse monitoring settings and data residency depend on deployment type and configuration, so we review these details with your security and legal teams during design.

How is Azure OpenAI related to Microsoft Foundry?

Microsoft Foundry, previously called Azure AI Foundry, is Microsoft’s platform for building AI applications and agents. Azure OpenAI models are offered in Foundry alongside models from other providers, together with tools for agents, evaluation, safety and monitoring. Existing Azure OpenAI resources and APIs continue to work. We design solutions with Foundry’s current project structure and help migrate older resources where useful.

Which deployment type should we choose?

Global Standard deployments generally offer the highest availability and capacity, Data Zone deployments keep processing within a geographic zone such as the EU or US, and regional Standard keeps processing in one region. Provisioned throughput reserves capacity for predictable latency at high volume, and Batch suits large asynchronous jobs at lower cost. We choose based on data residency, latency, volume and budget.

How do you prevent wrong or harmful answers?

We ground answers in your content with retrieval and require citations, restrict the assistant to its intended scope, and apply Azure AI Content Safety filters and prompt shields against jailbreak attempts. Before launch we evaluate quality, groundedness and safety on a test set built from real questions. In production we monitor answers, collect feedback and rerun evaluations whenever prompts, models or data change.

What does an Azure OpenAI solution cost to run?

Running costs consist mainly of model usage, charged per token or through provisioned capacity, plus supporting services such as Azure AI Search, storage, hosting and monitoring. Costs depend on traffic, prompt length, retrieved context and model choice. We estimate cost per transaction during the prototype and reduce it through prompt optimization, caching, model routing and choosing smaller models where they meet quality targets.

How long does it take to go live?

A focused prototype tested against an evaluation set typically takes four to six weeks. Hardening for production, including security review, integration, user testing and monitoring, usually adds several more weeks depending on complexity and approvals. Agents with multiple tool integrations take longer. We share progress through weekly written updates and sprint demos, so you see working software throughout.
