Azure Cosmos DB is part of Microsoft’s push to bring databases and Fabric together on a more unified data platform.

Arun Ulag covers Database Hub in Fabric, OneLake, Fabric IQ, AI agents, and more from FabCon and SQLCon 2026.

AI agents shouldn’t have an unlimited RU budget.

Riya Patel covers how to control Azure Cosmos DB costs with task-level RU budgets, query validation, call limits, result limits, partition-aware access, and telemetry.

What happens when your app goes from a few users to millions overnight?

At Azure Cosmos DB Conf 2026, Kirill Gavrylyuk sat down with Guillermo Rauch to talk about what modern applications—and AI agents—need from a database when scale arrives fast.

What happens when you actually build nine agentic AI design patterns on Azure instead of just diagramming them?

Steef-Jan Wiggers shares what worked, what broke, and lessons around Azure Cosmos DB RBAC, Foundry, Event Grid, Bicep, and more.

Vector search finds the candidates. Reranking decides what your RAG app actually reads.

Paul Vicente shows how retrieval, RRF, and learned reranking affect result ordering across Azure Cosmos DB and other Azure data services.

ICYMI: AI coding agents can generate working code fast—but will that code actually scale?

In Let the Agent Write It—But Can It Scale?, Sajeetharan Sinnathurai and Jay Gordon review agent-generated Azure Cosmos DB code with a focus on scalability, RU efficiency, indexing strategy, and long-term maintainability.

Give your AI agents durable memory with Azure Cosmos DB.

Theo van Kraay shows how `CosmosMemoryContextProvider` brings facts, summaries, profiles, and cross-session recall into Microsoft Agent Framework.

ICYMI: Your CI/CD pipeline can access Azure Cosmos DB without storing a client secret.

Iria Osara and Sudhanshu Khera walk through how workload identity federation, OIDC, Entra ID, Azure Cosmos DB RBAC, and `DefaultAzureCredential` work together for passwordless CI/CD.

Join Mark Brown and Kirill Gavrylyuk at FabCon Europe 2026 for a corenote on building agentic apps with Microsoft Fabric.

They’ll demonstrate persistent memory with Azure Cosmos DB, semantic search over OneLake, User Data Functions, mirroring, and Real-Time Intelligence.

Jesse Liberty has a clear, compact walkthrough of long-term memory in Microsoft Agent Framework, with Azure Cosmos DB as the durable store behind it.

Worth reading alongside the official documentation for the same reason a second explanation of anything is worth reading: he emphasizes different things, and the parts he chose to spend words on are usually the parts that confused him first.

Good entry point if you are a .NET developer approaching agent memory for the first time.

Your CI/CD pipeline doesn’t need a long-lived secret to access Azure Cosmos DB.

Iria Osara and Sudhanshu Khera show how workload identity federation, OIDC, Entra ID, RBAC, and DefaultAzureCredential enable passwordless CI/CD.

Vector search finds candidates. Reranking decides what your app reads. Treating them as one job is why RAG apps plateau at "mostly right."

Throughput choices should not be permanent architecture decisions. A workload can change long after launch, and the bill may be the first signal to revisit it.

This Azure Cosmos DB case study shows what that review found: https://t.co/UuvsHiXn1q

[Azure Cosmos DB @AzureCosmosDB]

FabCon and SQLCon 2026 are coming together around a single message: databases and Microsoft Fabric on one data platform.

For Azure Cosmos DB teams, the practical read is mirroring and the shrinking distance between operational writes and analytical queries. Worth a look at the session slate if analytics on operational data is on your roadmap.

If your orchestration layer and your data layer have different failover stories, you do not have a disaster recovery plan. You have two of them, and they will disagree at the worst possible time.

This piece on resilient Azure platforms works through Durable Functions and Azure Cosmos DB together so both layers share the same regional posture. Worth the read if you own an availability target you have never actually tested.
