Robust Architecture
Designed so your team ships features, not nightly fire drills. Every signal surfaces, every failure has context, every alert links to a runbook.
No silent failures. No 2 AM mysteries.
Every cron, queue, webhook, and workflow self-reports. If something stops, you know within 60 seconds — with the stack trace, the input that broke it, and a one-click rerun. Your team builds features. Mars handles the rest.
Observable by Default
Every API call, workflow step, and background job emits structured events with trace IDs. Filter, search, and replay them in the same UI you already use for incident history. No SDK to add, no agent to install.
Self-Healing Primitives
Retries with exponential backoff baked into every external call. Dead-letter queues catch what can't retry. ECS auto-replaces unhealthy tasks within 30 seconds — no human pages required for transient infra hiccups.
Idempotent Operations
Every webhook handler, payment action, and workflow trigger is idempotency-keyed at the boundary. Re-running yesterday's failed job is safe by design — no duplicate charges, no double-sent emails.
Audit-Grade Event Log
Every state change writes to an append-only event log with the actor, before/after diff, and full request context. Answering a 'how did this happen' question is a SQL query, not an archaeology dig through CloudWatch.
Synthetic Monitoring
Probes hit the critical paths — signup, workflow execution, agent inference — every 60 seconds from three regions. If the signup flow breaks at 2 AM, the on-call knows before the first customer reload.
Runbook-Driven Response
Every alert links to a documented runbook with steps, severity matrix, and escalation contacts. New on-call engineers handle their first incident on day 1, not week 6.
