Introduction

In the rapidly evolving world of Generative AI, balancing efficiency with data sovereignty is key. At HTCD, we leverage various leading-edge Large Language Models (LLMs) for our platform. This helps customers scale their cloud security team with an AI workforce — all while setting new standards in how we protect and manage data globally.

This blog shines a spotlight on our Azure OpenAI implementations — focusing on the architecture and insights we’ve gathered along the way. It marks the beginning of a series dedicated to unfolding HTCD’s journey and innovations with Generative AI. Our mission is clear: to offer global services that strictly adhere to customer, industry, and local data laws, while ensuring quick, reliable, and respectful data management everywhere.

The Challenge

In a world where data crosses borders with ease, we face a big question: How can we respect customers’ and countries’ data laws while keeping our services fast and reliable? For HTCD, this wasn’t just theoretical. When using Azure OpenAI, we ensure a user in Germany’s data is processed locally as opposed to a far-off US data center, and never stored. This was crucial not only for data sovereignty but also for reducing latency. We also wanted our clients not to worry about demographic-specific data storage laws like GDPR when they use our platform.

But what happens if a data center goes down? Relying on a backup in another region could violate our data sovereignty principle and commitments. We needed a smart system that keeps processing localized, and our services running smoothly.

Our Solution

We crafted a unique “Pattern-based Endpoint Design” to tackle this. Think of it as a map, with each region — such as the USA, EU, and Asia Pacific (APAC) — getting a specific pattern. Each has a primary and a backup Azure OpenAI endpoint. The primary handles all requests, while the backup provides resiliency, minimizes request throttling risks, and ensures data processing is limited to a home region or zone.

Choosing not to use a simple rotation system was deliberate. Our setup prioritizes local data handling and prepares us for future Azure enhancements, potentially offering even better regional service. Security is, of course, at the forefront of our design. We use Azure Managed Identities for secure key management, making authentication seamless and reducing the risk of breaches. It’s like having two locks on a door, ensuring only authorized access.

Special Focus on Scalability and Resilience

Our architecture is built to grow and adapt:

• Scalability: By assigning endpoints to specific regions, we can easily scale up services where demand spikes, without overloading the system.
• Resilience: With backup endpoints for each region, our services stay up even if a primary endpoint goes down, ensuring consistent access.
• Concurrency: The option of adding and removing Azure endpoints at will gives us the flexibility to cater to multiple users’ requests at the same time.

Azure API Management serves as our traffic director, smartly routing requests to the right place and keeping our service smooth and responsive.

Conclusion

HTCD’s innovative use of Azure OpenAI endpoints marks a new chapter in AI services, prioritizing data sovereignty and uninterrupted access. Our approach respects our customers’ policies and international data laws while guaranteeing fast, reliable service globally. In today’s digital age, where the value of data is unmatched, our architecture ensures security, speed, and compliance with global data regulations. HTCD is setting the standard for navigating the complex world of international data governance with agility and foresight.
