The ecosystem has rapidly moved from N×M brittle API integrations to decoupled, policy-enforced agentic infrastructure. As seen across AWS, Vercel, and the Model Context Protocol, top teams are treating LLMs not as intelligent users, but as untrusted runtime execution units that must be bounded by explicit, deterministic policies and unified state graphs.

In an industry relentlessly pushing the separation of compute and storage, Instacart achieved a 10x write reduction and halved their search latency by doing the exact opposite: ripping out Elasticsearch and moving text/vector search directly into their Postgres transactional database. By co-locating semantic vectors with real-time inventory data using pgvector, they eliminated massive application-layer data joins and expensive overfetching, proving that bringing compute directly to the data is often the superior architectural choice for latency-sensitive operational workloads.

Netflix’s choice to scale architectural linting across 5,000 repositories using raw ASM bytecode analysis rather than traditional AST parsing demonstrates a key platform engineering principle: analyzing compiled bytecode guarantees cross-language compatibility on the JVM and preserves deep class relationships that syntactic sugar often hides.
