## 📎 Executive Summary
### Architecture Overview
This is a **PCI-DSS Level 1 payment gateway** on Azure, designed for 10,000 TPS sustained throughput with 99.99% availability. The architecture follows a **hub-spoke network topology** with AKS as the compute platform, PostgreSQL Flexible Server for transactional data, and Cosmos DB for low-latency session state.
### Primary Optimization Pillar
**Security** — PCI-DSS v4.0 Level 1 compliance drives architectural decisions. All other pillars are optimized within PCI constraints.
### Architecture Pattern
| Attribute | Value |
| ---------------- | --------------------------------------------------------------------------- |
| **Pattern** | Hub-Spoke with Dedicated CDE |
| **Compute** | AKS Standard tier with zone-redundant node pools |
| **Data Tier** | PostgreSQL Flexible Server (ACID) + Cosmos DB (cache/session) |
| **Network Edge** | Azure Front Door Premium (WAF + DDoS) → Azure Firewall Premium (IDPS) → AKS |
| **API Layer** | API Management Premium (VNet-integrated) |
| **Messaging** | Service Bus Premium (dedicated capacity) |
| **Secrets** | Key Vault Premium (HSM-backed) |
| **Identity** | Entra ID + Workload Identity + PIM |
| **Monitoring** | Azure Monitor + Log Analytics (1-year retention) + Defender for Cloud |
### Key Architecture Decisions
| Decision | Choice | Rationale |
| --------------------- | ---------------------------------------- | ------------------------------------------------------------------------------------------------------- |
| Compute platform | AKS over ACA | PCI CDE isolation via dedicated node pools, Kubernetes network policies, OPA Gatekeeper |
| Database strategy | Dual DB (PostgreSQL + Cosmos DB) | ACID for transactions + sub-10ms for session/cache; reduces PostgreSQL connection pressure |
| Network segmentation | Hub-spoke + Azure Firewall Premium | IDPS required for PCI-DSS Req 1; east-west inspection between CDE and non-CDE |
| API gateway | APIM Premium (VNet) + Front Door Premium | VNet integration keeps API gateway inside CDE; Front Door provides global WAF + DDoS |
| Cosmos DB consistency | Session consistency | Sufficient for session state; avoids Strong consistency latency penalty while ensuring read-your-writes |
| Multi-region strategy | Active-Passive | Minimizes cost and Cosmos DB complexity; RPO ≤ 5 min achievable with geo-redundant PostgreSQL backup |

## 🏗️ WAF Pillar Assessment
### 🔒 Security — 9/10 (Confidence: High)
| Area | Score | Assessment |
| --------------------- | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Identity & Access** | 9/10 | Entra ID + Workload Identity for all service-to-service auth. PIM for JIT admin access. No shared accounts or passwords. |
| **Network Security** | 9/10 | Hub-spoke with Azure Firewall Premium (IDPS), NSGs, AKS network policies. Private endpoints for all data services. No public endpoints for CDE. |
| **Data Protection** | 9/10 | AES-256 encryption at rest with CMK for cardholder data. TLS 1.2+ everywhere. Key Vault Premium (HSM) for cryptographic keys. Tokenization for PAN. |
| **Threat Detection** | 8/10 | Defender for Containers, Defender for Cloud, Azure Firewall IDPS. Container image scanning pre-deployment. |
| **Compliance** | 9/10 | PCI-DSS v4.0 controls mapped to Azure services. 1-year log retention. Tamper-proof audit trail via Log Analytics. |
**Strengths**: Comprehensive PCI-DSS control mapping. Zero-trust architecture with managed identity everywhere. HSM-backed key management.
**Gaps**:
- Penetration testing schedule not yet defined (PCI Req 11)
- QSA validation of Azure Firewall IDPS as acceptable IDS/IPS control is pending
**Recommendations**:
1. Schedule quarterly penetration tests with a PCI-certified ASV
2. Implement Azure Policy deny rules for non-compliant configurations
3. Enable Defender for Key Vault for anomaly detection on cryptographic operations
---
### 🔄 Reliability — 8/10 (Confidence: High)
| Area | Score | Assessment |
| --------------------- | ----- | ------------------------------------------------------------------------------------------------------------- |
| **High Availability** | 9/10 | Zone-redundant AKS (3 AZs), PostgreSQL zone-redundant HA, Cosmos DB multi-AZ. Front Door global anycast. |
| **Disaster Recovery** | 7/10 | Active-passive to germanywestcentral. PostgreSQL geo-redundant backup (RPO ≤ 5 min). Manual failover process. |
| **Resilience** | 8/10 | KEDA autoscaling, pod disruption budgets, Service Bus dead-letter queues, idempotent transaction processing. |
| **Health Monitoring** | 8/10 | Liveness/readiness probes, Azure Monitor alerts, Defender continuous monitoring. Sub-minute alerting. |
**Strengths**: Zone-redundant deployment across all tiers. Idempotent transaction design prevents duplicate charges. Service Bus DLQ handles transient failures.
**Gaps**:
- Active-passive failover is manual — RTO ≤ 30 min depends on operator response time
- Cosmos DB failover to germanywestcentral is not yet configured
- No documented chaos engineering / game day testing plan
**Recommendations**:
1. Implement automated failover runbook with Azure Automation for RTO ≤ 15 min
2. Configure Cosmos DB multi-region with germanywestcentral as read-replica (can promote on failover)
3. Schedule quarterly chaos engineering tests (AKS node drain, zone failure simulation)
**Composite SLA Calculation**:
| Service | SLA | Zone-Redundant |
| ------------------------- | ------ | ----------------- |
| AKS Standard | 99.95% | 99.99% (with AZs) |
| PostgreSQL Flex HA | 99.99% | Yes |
| Cosmos DB (single-region) | 99.99% | Yes |
| Front Door Premium | 99.99% | Global |
| Azure Firewall | 99.99% | Yes (with AZs) |
| Key Vault | 99.99% | Yes |
| Service Bus Premium | 99.99% | Yes |
**Composite SLA**: 99.99% × 99.99% × 99.99% × 99.99% × 99.99% × 99.99% × 99.99% = **99.93%**
> [!WARNING]
> Composite SLA (99.93%) is below the 99.99% target. To achieve 99.99%, implement multi-region active-active for the most critical path (Front Door → AKS → PostgreSQL) or accept 99.95%+ with strong DR automation.

### ⚡ Performance — 8/10 (Confidence: Medium)
| Area | Score | Assessment |
| --------------- | ----- | ------------------------------------------------------------------------------------------------------------------------- |
| **Throughput** | 8/10 | AKS D8s_v5 nodes (8 vCPU, 32 GB) with KEDA autoscaling. 3-20 nodes supports 10-15k TPS. PgBouncer for connection pooling. |
| **Latency** | 8/10 | In-region P50 ≤ 100ms achievable. Cosmos DB session reads ≤ 10ms. PostgreSQL ≤ 20ms with connection pooling. |
| **Scalability** | 8/10 | Horizontal pod autoscaling + cluster autoscaler. Cosmos DB autoscale RU/s. PostgreSQL read replicas for reporting. |
| **Caching** | 7/10 | Cosmos DB for session/cache. No dedicated Redis layer — may need for response caching under extreme load. |
**Strengths**: KEDA enables event-driven scaling tied to Service Bus queue depth. Dual-database architecture offloads read-heavy cache operations from PostgreSQL.
**Gaps**:
- No dedicated Redis cache for API response caching — Cosmos DB may add latency vs. Redis for hot-path caching
- Load testing plan not yet defined to validate 15k TPS peak
- PgBouncer configuration (pool size, mode) needs tuning for 10k TPS
**Recommendations**:
1. Conduct Azure Load Testing at 15k TPS to validate node count and latency targets
2. Consider Azure Cache for Redis (Enterprise, 6 GB) as a hot-path cache if Cosmos DB latency exceeds targets under load
3. Configure PgBouncer in transaction mode with pool_size = 200 per pod
---
### 💰 Cost — 7/10 (Confidence: Medium)
| Area | Score | Assessment |
| -------------------- | ----- | ----------------------------------------------------------------------------------------------------- |
| **Right-Sizing** | 7/10 | D8s_v5 nodes are appropriate for 10k TPS. PostgreSQL E16s v5 may be oversized initially. |
| **Optimization** | 7/10 | Reserved instances recommended but not yet committed. Cosmos DB autoscale prevents over-provisioning. |
| **Monitoring** | 7/10 | Cost alerts should be configured. No FinOps process documented. |
| **Waste Prevention** | 6/10 | Dev/staging environments could use smaller SKUs. Spot nodes viable for non-CDE workloads. |
**Estimated Monthly Cost** (from Azure Pricing MCP — swedencentral):
| Category | Service | SKU | Unit Price | Monthly Cost |
| ------------------------------ | ----------------------- | ------------------------------ | ------------------------ | --------------------- |
| 💻 Compute (AKS management) | AKS Standard | Standard | $0.60/hr | $438 |
| 💻 Compute (AKS nodes × 6 avg) | D8s_v5 Linux | Standard_D8s_v5 | ~$0.408/hr | $1,787 |
| 💾 Database (Primary) | PostgreSQL Flex Server | Memory Opt E16s v5 (16 vCores) | $2.056/hr | $1,501 |
| 💾 Database (Cache) | Cosmos DB NoSQL | Autoscale 10K-50K RU/s | $0.012/hr per 100 RU/s | $876 – $4,380 |
| 🔐 Security | Key Vault Premium | HSM-backed | $0.03/10K ops | $22+ |
| 🌐 Network | Azure Firewall Premium | Premium | $1.75/hr | $1,278 |
| 🌐 Network | Azure Front Door | Premium | ~$330 base + per-request | $500 – $1,200 |
| 🛡️ DDoS | DDoS Network Protection | Standard | Fixed monthly | $2,944 |
| 🔀 API Gateway | API Management | Premium (1 unit) | $3.829/hr | $2,795 |
| 📊 Monitoring | Log Analytics | Per-GB ingestion | $2.99/GB | $300 – $1,500 |
| 📦 Container Registry | ACR Premium | Premium | $0.333/day | $10+ |
| 📨 Messaging | Service Bus | Premium (1 MU) | $0.9275/hr | $677 |
| 👤 Identity | Entra ID P2 + PIM | Per-user | — | $200 – $500 |
| | **TOTAL** | | | **$13,328 – $19,032** |
> [!NOTE]
> 💰 Prices sourced from Azure Pricing MCP (swedencentral, 2026-02-09). Production with full HA (20 nodes, max Cosmos RU/s) could reach ~$27,800/mo. Reserved Instances (1-year) save ~35% on compute and PostgreSQL.
**Savings Opportunities**:
| Opportunity | Est. Savings | Effort |
| ------------------------------------------------------ | ---------------------------- | ------------------------------------------ |
| 1-year Reserved Instances (AKS nodes + PostgreSQL) | ~35% on compute (~$1,150/mo) | Low |
| Spot nodes for non-CDE workloads (dev/test) | Up to 80% on dev compute | Medium |
| Cosmos DB autoscale floor (scale to zero off-peak) | 20-60% variable | Low |
| Log Analytics Commitment Tier (100 GB/day) | ~30% on ingestion | Low |
| Start with APIM Standard v2 → upgrade to Premium later | ~$2,100/mo initially | Medium — requires re-architecture for VNet |
---
### 🔧 Operations — 8/10 (Confidence: High)
| Area | Score | Assessment |
| --------------------- | ----- | ---------------------------------------------------------------------------------------------------- |
| **IaC** | 9/10 | Bicep with Azure Verified Modules. GitOps for AKS config. Repeatable, auditable deployments. |
| **CI/CD** | 8/10 | GitHub Actions with blue-green deployment. Container image scanning in pipeline. Automated rollback. |
| **Monitoring** | 8/10 | Azure Monitor + Application Insights + Defender. Distributed tracing. Alert thresholds defined. |
| **Incident Response** | 7/10 | On-call rotation assumed but not documented. Runbook templates needed. |
| **Documentation** | 7/10 | Requirements doc comprehensive. Operations runbook, DR plan needed before go-live. |
**Strengths**: Full IaC approach with Bicep/AVM. Blue-green deployment minimizes downtime. Container scanning gates prevent vulnerable images.
**Gaps**:
- No documented incident response playbook specific to payment failures
- Runbook for database failover not yet created
- Change management process for PCI CDE changes undefined
**Recommendations**:
1. Create payment transaction failure runbook with escalation paths
2. Document CDE change management process for PCI-DSS Req 6 compliance
3. Implement GitOps (Flux v2) for AKS workload deployments with audit trail
