Azure HorizonDB vs PostgreSQL pgvector vs AI Search for RAG
Azure HorizonDB reached public preview at Build 2026: a PostgreSQL-compatible, scale-out engine with vector search built in, up to 128 TB of storage and Sweden Central among the five launch regions. For RAG embeddings on Azure the choice now runs three ways, decided by where the source data lives, how much retrieval quality matters and how close you are to Flexible Server's vertical-scaling ceiling.
Running five coding agents at once in the GitHub Copilot app
GitHub’s new Copilot desktop app runs multiple coding agents in parallel, each session isolated in its own git worktree, and is already included in Copilot Pro, Pro+, Business and Enterprise subscriptions. Getting value from it depends less on prompting than on task selection, worktree hygiene, supervision cadence and engineered review capacity, because five agents can open pull requests faster than one reviewer can read them.
Build 2026 Foundry agents: what Azure teams can ship now
Microsoft Build 2026 turned Foundry into a full production-agent stack: Foundry IQ for unified retrieval, Toolboxes for managed tool access, agent memory, Voice Live and the experimental Scout Autopilot. Foundry IQ knowledge bases and Voice Live are generally available now, Toolboxes and memory sit in public preview, and Scout remains experimental, which sets the build, pilot and watch lanes for an Azure-first EU team.
