Kubernetes Production & SRE Architecture

Enterprise SRE Reference: Zero-IOPS Off-Heap Storage, CIS/SOC2 readOnlyRootFilesystem: true, and Cgroup Memory Budgeting.

TriCache is engineered specifically to eliminate the standard failure modes of stateful in-memory caching inside Kubernetes clusters: V8 garbage collection stalls, container OOMKills, EBS burst-credit exhaustion, and node eviction triggered by ephemeral storage exhaustion.

SRE Deep Dives

Explore the dedicated Kubernetes guides:

Topic	Focus Area	Key Architectural Advantage
/dev/shm Off-Heap tmpfs	Container Memory Bus	0.02ms latency off-heap RAM, zero V8 GC pauses, zero cloud EBS IOPS, compliant with readOnlyRootFilesystem: true.
Cgroup Memory Budgeting	Container Sizing	Cgroup v1/v2 enforcement, 40/40/20 heap-to-spill ratios, GC-aware OOM emergency purges.
Liveness vs. Readiness Probes	Traffic Routing	Hard separation between /healthz (process survival) and /ready (traffic admission & degradation).
Dynamic Latency Watchdog	Blast-Radius Shielding	Asymmetric Redis hysteresis and 4-stage graduated disk shedding under noisy-neighbor load.
Ephemeral Eviction Defense	Quota Safety	Proactive statfs host capacity checks, anti-eviction write shedding, and graceful SIGTERM snapshot flusher.
