Architecture

As autonomous AI agents evolve from isolated chatbots into orchestrators of complex, multi-pass software engineering tasks, the boundaries of execution become critical. In the Antigravity ecosystem, we rely heavily on specialized subagents—like DeepCoder and DeepInvestigator—to autonomously navigate codebases, test hypotheses, and execute shell commands. But what happens when an agent hallucinates a success? What happens when a long-running subagent hangs indefinitely? How do we prevent a deeply nested execution worker from going rogue and launching its own recursive subagents? ...

Running a complex fleet of microservices—spanning AI document assistants, vector databases, lossless audio streamers, private DNS resolvers, and astronomical APIs—demands complete, real-time visibility. But traditional enterprise observability suites (Elasticsearch, heavy Prometheus clusters, DataDog) frequently devour gigabytes of memory and CPU cycles just to monitor a small infrastructure. In this deep dive, I break down how we architected and deployed a complete, ultra-lightweight, 360-degree Observability, Logging, Analytics, and Uptime Stack across our 3-node hybrid cloud fleet at vinhthang.dev, maintaining sub-millisecond query latencies while consuming less than 250 MB total RAM! ...

How do you turn 3 separate Always Free cloud virtual machines into a resilient, production-grade, multi-architecture Kubernetes cluster capable of running high-performance relational databases, AI vector stores, lossless music streaming, and personal cloud storage? In this post, I will break down the complete architecture of our newly deployed 3-Node Hybrid K3s Cluster running on Oracle Cloud Infrastructure (OCI) under our custom domain vinhthang.dev. 🏛️ The 3-Node Cluster Topology Oracle Cloud’s Always Free tier offers an incredible set of compute resources: ...
