Introduction: LLM API calls are expensive and slow—semantic caching reduces both by reusing responses for similar queries. Unlike exact-match caching, semantic caching uses embeddings to find queries that are semantically similar, even if worded differently. This enables cache hits for paraphrased questions, reducing latency from seconds to milliseconds and cutting API costs significantly. This guide […]

Scaling Up Your Pods: How Horizontal Pod Autoscaling Wins
After two decades of managing containerized workloads across production environments, I’ve come to appreciate that the difference between a good Kubernetes deployment and a great one often comes down to how intelligently it responds to changing demand. Horizontal Pod Autoscaling (HPA) represents one of those fundamental capabilities that separates reactive operations from proactive infrastructure management. […]
Read more →Streaming LLM Responses: Building Real-Time AI Applications
Introduction: Waiting 10-30 seconds for an LLM response feels like an eternity. Streaming changes everything—users see tokens appear in real-time, creating the illusion of instant response even when generation takes just as long. Beyond UX, streaming enables early termination (stop generating when you have enough), progressive processing (start working with partial responses), and better error […]
Read more →Prompt Injection Defense: Sanitization, Detection, and Output Validation
Introduction: Prompt injection is the most significant security vulnerability in LLM applications. Attackers craft inputs that manipulate the model into ignoring instructions, leaking system prompts, or performing unauthorized actions. Unlike traditional injection attacks, prompt injection exploits the model’s inability to distinguish between instructions and data. This guide covers practical defense strategies: input sanitization, injection detection, […]

Running production workloads on Amazon EKS demands more than basic health checks. After managing dozens of Kubernetes clusters across various industries, I’ve learned that the difference between a resilient system and a fragile one often comes down to how deeply you can see into your infrastructure. This guide shares the observability patterns and CDK-based automation […]
