Secure, Observable, Cost-Smart Platform—As Code

Kubernetes (K8s) gives you a standardized, portable runtime for containers—when designed with security, governance, and evidence baked in.
SolveForce builds Kubernetes platforms that are secure-by-default, GitOps-driven, observable, and cost-aware across AWS/EKS, Azure/AKS, GCP/GKE, and on-prem—wired to identity, keys, and policy so you can ship fast and pass audits.

How K8s fits the SolveForce system:

🎯 Outcomes (Why SolveForce K8s)

  • Platform as code — clusters, add-ons, and policies are reproducible, reviewed, and versioned.
  • Secure-by-default — mTLS, admission controls, allowed images, least privilege, and network segmentation.
  • Observable & SLO-driven — golden signals, traces, and release markers tied to error budgets.
  • Cost-smart — autoscaling, bin-packing, spot/priority, and right-sizing baked into the design.
  • Audit-ready — every deploy and policy decision ships evidence to SIEM with change IDs.

🧭 Scope (What we build & operate)

  • Clusters & node groups — managed control planes (EKS/AKS/GKE) and on-prem; Linux + optional Windows pools; GPU/accelerator pools.
  • Networking (CNI) — CIDR & IPAM, NetworkPolicy, egress policies, Ingress/Layer-7 gateways.
  • Service mesh (optional) — mTLS, L7 intent/policy, traffic splits, retries/timeouts, telemetry.
  • Storage — CSI drivers, dynamic PVCs, snapshots/backup/restore.
  • GitOps — Argo CD/Flux for declarative state; drift detection and reconcile.
  • Security — admission control (Gatekeeper/Kyverno), image policy/attestations, secrets, RBAC, Pod Security, runtime controls.
  • Observability — Prometheus/OTel metrics, logs, traces; dashboards, alerts, and SLOs.
  • FinOps — HPA/VPA, Cluster Autoscaler/Karpenter, bin-packing, spot/priority classes.

🧱 Building Blocks (Spelled out)

  • Provisioning & IaC — Terraform/CloudFormation/Bicep/Pulumi + cluster add-on managers; remote state + Object Lock. → Infrastructure as Code
  • Identity & RBAC — OIDC federation, short-lived tokens, groups→roles mapping, namespace tenancy. → IAM / SSO / MFA
  • Networking — CNI (VPC-CNI/Cilium/Calico), NetworkPolicy default-deny, egress allow-lists, private endpoints.
  • Ingress/L7 — Ingress controller or Gateway API; WAF at the edge; mTLS to services where required. → WAF / Bot Management
  • Certificates/PKI — cluster & mesh mTLS, service cert rotation (SPIFFE/SVID or ACME). → PKI
  • Secrets — CSI Secrets Store, vault sidecar, Transit encryption; no plaintext in manifests. → Secrets ManagementEncryption
  • Supply chain — SBOMs (SPDX/CycloneDX), image signatures (Cosign/Sigstore), admission verify + policy as code.
  • Policies — Gatekeeper/Kyverno guardrails (proc caps, root fs ro, host-net/IPC bans, trusted registries, labels/owners).
  • Runtime — seccomp, AppArmor, read-only FS, minimal capabilities, eBPF runtime sensors.

🏗️ Reference Architectures

A) Internet-facing microservices (cloud-native)

  • EKS/AKS/GKE with Ingress/Gateway → service mesh (mTLS, retries) → HPA/VPA + Cluster Autoscaler → WAF/CDN at edge; GitOps deploys.
  • Policies: default-deny NetworkPolicy, signed images only, Pod Security “restricted”.

B) Data & AI platform

C) Regulated workloads (PCI/HIPAA/NIST)

D) Hybrid/on-prem with cloud burst

  • On-prem clusters for data gravity; cloud clusters for elastic jobs; secure interconnect; shared GitOps; consistent policies across fleets.

🔒 Security & Zero-Trust (Concrete controls)

  • Admission — deny unsigned/unattested images; enforce labels/owners; block privileged pods/hostPath; PSL “restricted”.
  • Identity — OIDC SSO/MFA for humans; service identity via SPIFFE or short-lived certs/tokens.
  • Network — default-deny; only declared Service→Service flows; egress DNS/TLS allow-lists. → Microsegmentation
  • Boundary — WAF/Bot at edge; origins cloaked; mTLS north-south to services. → WAF / Bot Management
  • Secrets — vault + CSI; rotated and short-lived; Transit for encryption. → Secrets Management
  • Keys — HSM/KMS custody; envelope encryption; dual-control. → Key Management / HSM
  • Ops safety — break-glass via PAM; session-recorded; cluster admin separated. → PAM

📦 Storage & Backup/DR

  • CSI drivers — dynamic PVCs; snapshot/restore classes; topology-aware provisioning.
  • Backups — Velero-style or vendor; etcd + PVC snapshots; restore drills with artifacts.
  • DR patterns — app-level replication; multi-region clusters; failover runbooks.

📈 Observability & SLOs

  • Metrics — Prometheus/OTel + recording rules; golden signals (latency, traffic, errors, saturation).
  • Traces/logs — OpenTelemetry → backend; correlate with release markers; error budgets drive rollouts.
  • Dashboards & alerts — per service/team; SLO widgets; alert on saturation and 95p/99p tail.
  • SIEM — audit, kube-api, admission, image policy, and network denies to SIEM; SOAR handles rollback/quarantine. → SIEM / SOAR

📐 SLO Guardrails (Experience & safety you can measure)

SLO / KPITarget (Recommended)
Pod start (p95)≤ 5–15 s (image cached), ≤ 30–60 s (cold)
Deployment success rate≥ 99% (post-canary)
Admission policy eval (p95)≤ 100–300 ms
P99 service latency budget add≤ +5–15 ms from mesh/L7 polices
Cluster availability≥ 99.9–99.99% (control plane)
Image pull time (p95)≤ 3–10 s (with registry cache)
Evidence completeness (releases)100% (plan, tests, approvals, logs)

SLO breaches pause promotions and trigger SOAR (rollback, scale, or route-shift). → SIEM / SOAR


💰 FinOps (Cost that behaves)

  • Right-size requests/limits; VPA hints; bin-packing with topology spread.
  • Autoscaling — HPA (CPU/QPS/custom), VPA (recommend/apply), Cluster Autoscaler/Karpenter.
  • Spot/priority — mix spot/ondemand; PDBs & priorities; disruption budgets.
  • Caching & images — local registry caches; layer reuse; buildx/cache-to-from in CI.

🧰 Supply Chain & CI-CD

  • SBOM on every build; dependency scanning; license policy gates.
  • Image signing with Cosign; verify in admission; attestations for provenance.
  • Progressive delivery — canary/blue-green/traffic splits; auto-rollback on SLO dip.
  • GitOps — PR-gated desired state; drift detection & reconcile; evidence to SIEM.

📜 Compliance Mapping (Examples)

  • PCI DSS — segmentation, encryption, WAF evidence, audit logs/export.
  • HIPAA — least privilege, secrets custody, immutable logs, DR drills.
  • ISO 27001 — ops security, access control, change evidence.
  • NIST 800-53/171 — AC/AU/SC/CM families; admission + logging.
  • CMMC — configuration & access maturity; evidence packs exportable.
