Ship Faster, Scale Instantly, Pay for What You Use — With Evidence
Serverless turns infrastructure into managed, event-driven services (functions, queues/streams, schedulers, managed DB/storage) so teams ship faster with automatic scale and fine-grained cost control—without sacrificing security or auditability.

🎯 Outcomes (Why Serverless with SolveForce)
- Speed — idea → prod with managed runtimes, API gateways, queues, schedulers, and managed DBs.
- Scale — auto-scale to zero and to peak; regional & multi-AZ by default.
- Security by default — least-privilege IAM, short-lived credentials, keys in HSM/KMS, secrets in vault.
- Lower TCO — pay per request/duration; provisioned concurrency only where it pays off; right-size memory for latency/$ balance.
- Evidence — structured logs, traces, policies, and changes stream to SIEM/SOAR for audits.
🧭 Scope (What We Build & Operate)
- Functions & APIs — Functions-as-a-Service behind API gateways (REST/GraphQL/WebSocket); custom domains; WAF/Bot protection. → /waf
- Events & Workflows — queues/streams (Kafka/EventBridge/Event Hubs/Pub/Sub), schedulers, saga/step functions for long-lived workflows.
- Data — managed DBs (NoSQL/SQL/time-series), object storage, event-driven ETL/ELT into lake/warehouse. → /etl-elt • /data-warehouse
- AuthN/Z — OIDC/OAuth2/JWT, signed requests; ZTNA for admin tools; SASE for web/SaaS. → /ztna • /sase
- Observability & Ops — logs/metrics/traces, cold-start heatmaps, dead-letter queues, SLO dashboards → SIEM/SOAR. → /siem-soar

- Reliability Patterns
- Idempotency keys; retries with jitter; DLQs & poison-pill handling; exactly-once effects via dedupe stores/locks; circuit breakers.
- Data & AI
- Event-driven ELT; dbt models; vector DB for RAG with cite-or-refuse; privacy labels & DLP on egress.
→ /vector-databases • /dlp - Networking
- Private integrations (VPC/VNet links) to DBs and services; egress control; split-DNS; Anycast/CDN for edge APIs.
🧰 Reference Patterns (Choose Your Fit)
A) API-First Microservices
Functions + API Gateway; per-route auth; WAF/Bot; DDoS; idempotency & DLQ; canary deploys with automated rollback.
B) Event-Driven Backends
Producers → queue/stream → functions → DB/object store; saga/step functions for orchestration; exactly-once effects via idempotency store.
C) Batch & Schedules
Cron/scheduler events; shard large jobs; checkpoint/resume; cost caps; emit lineage & DQ tests for each run.
D) Serverless Data Ingest & ELT
Ingest to object/stream; auto-validate schema; quarantine bad records; ELT into warehouse; quality gates; lineage in catalog.
E) Real-Time Notifications & WebSockets
Gateway WebSockets/SignalR; auth tokens; connection fan-out via pub/sub; backpressure policy; cost guards.
F) Media/Files Pipeline
Pre-signed uploads; antivirus/transcode/thumbnail as events; DRM/watermarking; lifecycle/retention controls.
📐 SLO Guardrails (Targets You Can Measure)
| SLO / KPI (p95 unless noted) | Target (Recommended) |
|---|---|
| Cold start (Java/Node/Python) | ≤ 200–800 ms (provisioned where needed) |
| Warm invoke latency (API route) | ≤ 20–100 ms + downstream |
| End-to-end API (edge→func→DB) | ≤ 150–400 ms regional |
| Event processing freshness | ≤ 1–60 s by queue/stream class |
| DLQ rate (steady-state) | ≤ 0.1% of total messages |
| Error budget burn (30d) | Within SLO (alerts at 25/50/75%) |
| Deploy rollback time | ≤ 2–5 min (auto on SLO breach) |
| Evidence completeness (changes/incidents) | = 100% (plans, logs, approvals, artifacts) |
SLO breaches open tickets and trigger SOAR playbooks (rollback, reroute, re-key, quarantine). → /siem-soar
🔒 Compliance & Privacy
- SOC 2 / ISO 27001 — access/change/logging controls; exportable evidence.
- HIPAA/PCI/GDPR/CCPA — encryption & tokenization, least privilege, DLP on egress, residency & retention policies.
- Model/AI governance — RAG with citations; model cards & data lineage for training/eval.
💸 FinOps for Serverless (Cost That Behaves)
- Right-size memory for latency/$; measure tail latency vs cost.
- Use provisioned concurrency only where cold-start SLOs require it; cap with schedules.
- Batch & aggregate to reduce invocations; compress payloads; cache results.
- Reserved concurrency to prevent noisy-neighbor spikes; budgets/alerts & anomaly tickets. → /finops
📊 Observability & Evidence
- Structured logs with correlation IDs; traces across gateway→function→DB; cold-start annotations.
- Metrics: invocations, duration, concurrency, errors, throttles, DLQ depth, e2e latency.
- Security: auth decisions, WAF/Bot hits, KMS/Key Vault events; CI/CD change diffs.
All streams feed SIEM; SOAR automates contain/rollback/report. → /siem-soar
