The Infrastructure Layer Enterprises Need for Production LLM Systems

Large language models are easy to prototype with. They are not easy to operate at enterprise scale. Over the past two years, many teams have successfully launched LLM-powered copilots, internal assistants, automation tools, and customer-facing AI features. But as usage grows, traffic patterns change, and workloads become unpredictable, a new class of problems emerges: Latency spikes under load Memory instability Logging systems interfering with request performance Gradual performance degradation over time Operational complexity around restarts and scaling At small scale, these issues are tolerable. At enterprise scale, they become infrastructure risks. This is where the idea of a dedicated infrastructure layer for LLM systems becomes critical. The Hidden Bottleneck in Production LLM Systems In early-stage deployments, routing requests to models feels straightforward: Application → LLM SDK → Model Provider But as organizations mature, requirements grow: Multi-model routing Rate limiting
