-  executive_summary: >
-    PharmaCorp Mexico operates 3 mission-critical Oracle databases (EBS R12, SAP, DW)
-    on aging Exadata X6 hardware. The hardware refresh quote is $1.8M and locks the
-    company into 5 more years of on-prem operations with no DR capability. Migration
-    to OCI ExaCS X11M reduces annual infrastructure costs by 61% ($1.75M over 3 years),
-    adds cross-region DR (RPO<15min, RTO<1h), and resolves the pending SOX audit
-    finding on automated patching.

-
-  recommendation:
-    summary: >
-      Proceed with OCI ExaCS migration. 61% cost reduction over 3 years ($1.75M saved),
-      cross-region DR capability, and SOX compliance resolution. The alternative
-      (HW refresh at $1.8M) costs more and leaves DR + compliance gaps unresolved.

-# OCI Deal Accelerator — Proposal Spec
-# Demo: Pharma Mexico — ExaCS migration from on-prem Exadata X6
-# Prompt 1: Full proposal
-
-metadata:
-  customer: "PharmaCorp Mexico"
-  project: "Oracle Database Migration to OCI"
-  subtitle: "ExaCS Migration — Exadata X6 to OCI"
-  architect: "Carlos Mendoza"
-  firm: "Oracle Cloud Infrastructure"
-  date: "2026-04-12"
-
-summary:
-  why: >
-    PharmaCorp Mexico operates 3 Oracle databases (EBS R12, SAP, DW) on on-premises
-    Exadata X6 hardware approaching end-of-life. Hardware refresh costs $1.8M and
-    locks into 5 more years of on-prem operations. Migration to OCI ExaCS provides
-    30%+ cost reduction, eliminates hardware lifecycle management, improves DR posture
-    (RPO<15min, RTO<1h), and enables SOX compliance alignment with Oracle-managed
-    infrastructure patching.
-  current_state:
-    - "3 Oracle DBs on Exadata X6 (EBS R12 prod, SAP, Data Warehouse)"
-    - "200 concurrent users, peak during fiscal close"
-    - "2TB total data across all databases"
-    - "No DR — single site in Mexico City data center"
-    - "Manual patching quarterly — SOX audit finding pending"
-    - "HW refresh due in 6 months ($1.8M quote)"
-  target_state: >
-    OCI ExaCS X11M in Queretaro (prod) with Data Guard standby in Sao Paulo for
-    cross-region DR. Hub-spoke networking via DRG, dual FastConnect 10Gbps for
-    redundancy, WAF for web applications, OCI Vault for TDE key management.
-    SOX compliance via automated patching and audit logging.
-  timeline: "Migration Q3-Q4 2026 (16 weeks) — conditional on board approval Q2"

-      name: "HA for Business Continuity"
-      summary: "Design for HA proportional to business impact"
-      rationale: "EBS is Platinum tier — needs cross-region DR"
-    - id: "D-06"
-      name: "Defense in Depth"
-      summary: "Multiple security layers, not single perimeter"
-      rationale: "SOX compliance requires network segmentation + encryption + audit"
-  deployment:
-    - id: "P-01"
-      name: "Infrastructure as Code"
-      summary: "All infrastructure defined in Terraform"
-      rationale: "Reproducible environments, audit trail for SOX"

-    Dual-region ExaCS deployment: Queretaro (primary) + Sao Paulo (DR standby).
-    Hub-spoke networking with DRG provides segmented VCNs for each workload tier.
-    Dual FastConnect 10Gbps from Mexico City provides redundant connectivity.
-    WAF protects EBS web tier. OCI Vault manages TDE encryption keys externally.
-
-    Key components:
-    - ExaCS X11M Quarter Rack in Queretaro (3 databases)
-    - Data Guard to ExaCS standby in Sao Paulo (EBS + SAP)
-    - Hub VCN with DRG for inter-spoke routing
-    - Dual FastConnect 10Gbps from Mexico City DC
-    - WAF for EBS R12 web access
-    - OCI Vault for TDE key management (SOX)

-decisions:
-  - title: "ExaCS over ADB-S"
-    decision: "Use ExaCS instead of ADB-S for all 3 databases"
-    rationale: >
-      EBS R12 requires OS-level access for patches and customizations.
-      SAP on Oracle requires specific Oracle features not available on ADB-S.
-      DW benefits from ExaCS storage performance. All 3 share the same
-      Exadata infrastructure for cost efficiency.
-    alternatives: "ADB-S (rejected — EBS needs OS access), DBCS (rejected — no Exadata performance)"
-
-  - title: "Cross-Region DR with Data Guard"
-    decision: "Active Data Guard from Queretaro to Sao Paulo"
-    rationale: >
-      RPO<15min requires real-time redo shipping. Sao Paulo provides geographic
-      separation for disaster scenarios. Data Guard supports automatic failover
-      with FSDR for RTO<1h.
-    alternatives: "Backup/restore (rejected — RPO 24h), Same-region standby (no geo separation)"
-
-  - title: "Hub-Spoke Networking"
-    decision: "Hub VCN with DRG for inter-spoke routing and segmentation"
-    rationale: >
-      SOX requires network segmentation between environments. Hub-spoke with DRG
-      provides centralized security controls (WAF, NSG) while isolating workloads.
-    alternatives: "Flat VCN (rejected — no segmentation for SOX)"
-
-  - title: "Dual FastConnect"
-    decision: "Two 10Gbps FastConnect circuits from Mexico City"
-    rationale: >
-      Single FastConnect is a documented single point of failure. Dual circuits
-      provide redundancy for the EBS production workload.
-    alternatives: "Single FastConnect + IPSec VPN backup (acceptable for lower tiers)"
-
-  - title: "OCI Vault for TDE Keys"
-    decision: "External key management via OCI Vault instead of Oracle Wallet"
-    rationale: >
-      SOX requires separation of duties for encryption key management.
-      OCI Vault provides FIPS 140-2 Level 3 HSM-backed key storage.
-    alternatives: "Oracle Wallet on ExaCS (simpler but no separation of duties)"
