Distributed ad serving with low latency
Distributed ad serving in streaming: how to fit within 100 ms while balancing latency, personalization, and system resilience
Observability
Observability on ThecoreGrid focuses on understanding, monitoring, and debugging complex distributed systems in production.
We cover logging, metrics, tracing, and profiling as core pillars for gaining visibility into system behavior under real workloads. Topics include instrumentation strategies, telemetry pipelines, alerting design, SLI/SLO definition, and incident detection in highload environments. We analyze trade-offs between signal quality, cost, and system overhead, along with challenges of cardinality, sampling, and data retention. Content is grounded in BigTech practices, including incident post-mortems and lessons from operating large-scale systems. You’ll find deep dives into modern observability stacks, correlation techniques, and debugging methodologies for microservices and cloud-native platforms. Instead of tool-focused tutorials, the Observability tag delivers engineering insights for SREs, platform teams, backend engineers, and architects responsible for system reliability, performance, and operational transparency.

LLM Serving Workload Analysis FineServe Without Illusions
LLM serving workload turns out to be significantly more complex than is typically modeled. FineServe demonstrates how real workloads break simplified assumptions and impact architecture. Modern LLM platforms operate as always-on services with strict requirements for latency and throughput. The main issue is the unstable and heterogeneous LLM serving workload. Most studies have relied on … Read more
