Context Caching
When every request starts with the same long instructions, a service can reuse its work on that prefix. It pays off only if the prefix really is identical.

-
Cold Start
Measure initialization code, runtime startup, and dependency delays against the workload deadline before choosing a startup mitigation.
-
PACELC
PACELC adds what CAP omits: when there is no partition, you are still trading latency against consistency — and that is the trade you live with daily.
-
Quality Attributes and Trade-offs
Fast, reliable, and scalable mean different things to different teams. Define each quality precisely, measure it, and see where improving one costs another.
-
Cloud Inference with Big Payloads
Large inference inputs affect transfer, memory, and deadlines. Compression, resumable upload, and asynchronous processing solve different problems.
-
Speech Recognition, Synthesis, and Streaming
Follow audio from waveform to transcript and back to speech, with runnable examples of features, CTC, endpointing, latency budgets, WER, and redaction.
-
Network Retries and Timeouts for Data Pipelines
Trace network and storage delays, handle uncertain writes safely, and verify a download before making it visible.
