🚦 The control plane for GenAI APIs: AI Gateway in Azure API Management 🛡️ When you see development teams rush to “just connect to the model,” you need to pause. As soon as you have multiple apps, teams, or agents calling LLM endpoints, you need consistent controls - not scattered client-side logic. Here’s how AI gateway in Azure API Management helps you frame it through a security & compliance lens: ❓ So, what are we talking about here? 🔹 A set of APIM capabilities to manage, secure, scale, monitor, and govern LLM deployments, AI APIs, and MCP servers used by apps and agents. 🔹 It extends the existing APIM gateway (not a separate offering). 🔹 Applies to all API Management tiers. ❓ Security & safety controls to prioritize: 🔹 Managed identities to authenticate to Azure AI services (so you don’t need API keys). 🔹 OAuth authorization for apps/agents accessing APIs or MCP servers using APIM credential manager. 🔹 Policies to automatically moderate LLM prompts using Azure AI Content Safety. ❓ Compliance, auditability, and governance signals: 🔹 Log prompts and completions to Azure Monitor. 🔹 Track token metrics per consumer in Application Insights and use the built-in monitoring dashboard. 🔹 Enable logging to support billing and auditing of token usage, prompts, and completions (and analyze in Application Insights). ❓ Abuse & cost guardrails that double as policy controls: 🔹 Enforce token rate limiting / quotas (TPM limits or quotas over time - hourly/daily/weekly/monthly/yearly). 🔹 Apply token limits by subscription key, client IP, or any custom counter key, and even precalculate prompt tokens to avoid unnecessary backend calls when a prompt already exceeds limits. ❓ And remember, resiliency is a tenant of systems security CIA triad (Confidentiality, Integrity, and Availability): 🔹 Configure multiple backends and use APIM load balancing (round-robin, weighted, priority-based, session-aware). 🔹 Use circuit breaker with dynamic trip duration (uses Retry-After from backend) to stop forwarding to unhealthy backends. 💡 If you’re building intelligent apps or agents, my rules are simple: ✅ Put your models and MCP servers behind the gateway. ✅ Turn on identity, token controls, content safety, and logging. ✅ Make governance measurable through metrics + dashboards. 📸 High-resolution images of my infographics are available for download on my blog website in the perspective corresponding article. #MicrosoftSecurity #Cybersecurity #Azure #APIM #GenAI #SecurityForAI #AzureOpenAI #MCP

Stop treating your API like infrastructure. The most successful API companies know something you don't: APIs are products, and they need Product Managers. I recently sat down with Derric Gilling, CEO of Moesif (A WSO2 Company), for a wide-ranging chat about all things API PM. Our key learnings: Practical takeaways you can apply this quarter. 1. Assign (or formalize) API Product Management. If no one owns the outcomes, you’ll default to inside-out decisions that miss the market. Even if a lead engineer is doing parts of the job, give them the mandate and support to own it end-to-end. 2. Build dual-persona roadmaps. For any new endpoint, ask: what does the integrator need, and what does their end-user desire? 3. Instrument the lifecycle. Make it trivial to see activation, adoption, version migration, and usage concentration by account. Bring these views into weekly product and revenue conversations - more on this below. 4. Treat internal APIs as products. Create a lightweight discovery cadence with internal teams, standardize style guides, and ship docs and dashboards they’ll actually use. 5. Embrace AI for structure, not shortcuts. Use LLMs to draft OpenAPI, schemas, and policy templates. Then review rigorously and wire them into your CI for tests, linting, breaking-change checks, and doc generation. Common pitfalls (especially for ex-engineers moving into PM) • Prescribing solutions and architecture instead of defining the problem, outcomes, and constraints. • Swinging too far the other way & losing technical currency. API PMs must keep up with new protocols like MCP, AI tooling, and modern delivery practices to make smart tradeoffs. Balance product thinking with ongoing technical depth. Metrics that matter (instrument the whole journey) • Top-of-funnel: signups, % and time to First API Call • Mid-funnel activation: number of API calls, breadth of endpoints used, feature/API adoption, time-to-first meaningful workflow. • Version lifecycle: migration from old to new APIs - deprecation safety (who’s still on v1?). • Monetization & PLG signals: heavy users approaching rate limits/quotas, accounts expanding usage, users who signed up but never made a call (reach out to them today). This visibility informs both product and go-to-market motions. Check out the full interview on YouTube and let me know what your favorite takeaway was.

Title “Architecting Scalable Multi-Vendor APIs with AWS API Gateway" The architecture diagram reflects a sophisticated AWS API Management setup, designed to cater to a multitude of vendors and service consumers. At the heart of this architecture lies the AWS API Gateway, acting as the conductor, directing various types of HTTP(S) requests – GET, POST, PUT – to the appropriate AWS services. It serves as the single entry point for all incoming traffic, ensuring a managed and monitored interaction with backend services. Vendor Diversification and Endpoint Management: The architecture showcases how different vendors – Vendor1, Vendor3, Vendor5 – interact with the AWS Cloud via the internet, utilizing RESTful API calls. This variety in vendors highlights the API Gateway's capability to handle multiple endpoints securely and efficiently. Lambda Integration for Dynamic Execution: The integration of AWS Lambda functions with the API Gateway is a testament to the flexibility of AWS services. Each HTTP method is tied to a corresponding Lambda function, allowing for serverless computing where code is executed in response to requests, scaling automatically with the size of the workload. HTTP and VPC Link Integrations: In scenarios where direct AWS service integrations are not viable, the architecture provides alternatives. Some API Gateway instances are integrated via HTTP, facilitating communication with external HTTP endpoints. Meanwhile, the VPC Link is used for secure, private connections to services hosted within an Amazon Virtual Private Cloud (VPC), represented here by two availability zones, az1 and az2. S3 and Third-Party API Interactions: The AWS ecosystem's versatility is further exemplified by the S3 bucket integration for file upload/download operations, and the interaction with third-party or open-source APIs, allowing the architecture to extend beyond the AWS boundaries. Conclusion: This AWS API Management architecture is a robust framework that not only simplifies the integration of various services but also ensures a secure, scalable, and efficient system. It demonstrates the potential to adapt to different service models, from serverless computing to traditional HTTP-based applications, and the ability to connect securely to internal resources within a VPC. As businesses continue to evolve and integrate more diverse services, architectures like this will be pivotal in managing the complexity of modern cloud ecosystems.

Most companies don't have an API problem. They have an API discovery problem. How to address it? Your APIs already run on AWS, Azure, or other gateways. They work fine. The real challenge? Nobody can find them, understand them, or adopt them easily. Every API integration requires multiple calls and months of dev work. Here's what typically happens: • APIs scattered across Postman, GitHub, and multiple gateways • Documentation is outdated or buried in Confluence • Internal teams asking, "Wait, do we have an API for that?" • Potential partners are unable to onboard themselves • Compliance and governance nightmares    Sound familiar? This is where a proper developer portal changes everything. Not another gateway. Not more infrastructure. Just one unified portal where all your APIs live, are documented, and ready to use. This is exactly what Digitalapi.ai, partner of this post, does: 1) Auto-discovery across your entire stack Connect your AWS gateways, Postman workspaces, and GitHub repos. AI automatically finds, catalogs, and documents every API. No manual work needed. 2) AI-powered documentation that never gets stale Every endpoint update is instantly reflected in your docs. Internal teams and external partners always see the current state, eliminating the number 1 reason integrations fail. 3) Built-in governance and compliance Automatic checks ensure your APIs meet security standards and compliance requirements. No more manual audits or spreadsheet tracking. You know something is wrong the moment an issue is introduced. 4) Branded portal for 3rd party adoption Open your APIs to external developers through a professional, branded portal. They can discover, test, and integrate, all self-service. That means so many fewer calls! 5) Monetization built in Turn API access into revenue with subscription tiers, usage-based pricing, and automated billing. Your APIs become a business channel, not just a technical feature. Just like it always should have been. The result? • Internal teams find and use existing APIs instead of rebuilding them • Partners onboard themselves without bothering your engineering team • New revenue streams from API subscriptions • Faster integrations = faster partnerships = faster growth Your API already exists. Make it discoverable, governable, and monetizable. Check out http://www.DigitalAPI.ai and see how a proper dev portal transforms scattered APIs into a growth engine.

Traffic Management in SAP API Management: Controlling API Usage with Policies APIs are powerful, but without proper controls, they can be overwhelmed or misused. That’s where Traffic Management Policies in SAP API Management step in. These policies help you protect backend systems, maintain stability, and enforce fair usage across consumers. Here are the key tools available: 1️⃣ Rate Limiting Control the number of API calls allowed per client per time window. Example: Allow max 100 requests per minute. 2️⃣ Quota Define long-term usage limits like daily or monthly caps. Example: Allow 10,000 requests per month per API key. 3️⃣ Spike Arrest Smooth out sudden traffic spikes by spacing out incoming requests. Example: Allow only 2 requests per second, great for APIs exposed to public users. 4️⃣ Concurrent Rate Limiting Limit how many requests can be processed at the same time. Ideal for preventing overload on synchronous, resource-heavy services. All of these policies are easy to configure and apply within the API proxy flow, no code changes needed on the backend.
