# Discovery Call — Banco Pacífico (fake name) — 2024-11-14
|
|
|
|
Attendees: Maria (SA), Jorge (CTO), Ana (DBA lead), Mike (infra mgr)
|
|
45 min call, mostly Jorge talking
|
|
|
|
---
|
|
|
|
## Current State (what I could gather)
|
|
|
|
- 3x Oracle 19c databases on Exadata X8M on-prem
|
|
- largest one is ~4TB, OLTP workload (core banking txns)
|
|
- second is ~1.2TB — reporting/analytics, runs batch overnight
|
|
- third is smaller, ~300GB, "auxiliary services" — Jorge was vague here ??
|
|
- GoldenGate replication between prod and DR site (San Jose DC)
|
|
- Ana mentioned 99.95% availability SLA — "contractual, can't go lower"
|
|
- PCI DSS compliance — mandatory, they process card transactions
|
|
- ~~2 RAC nodes~~ correction: 3 RAC nodes on the big DB, 2 on the others
|
|
|
|
## Licensing / Cost
|
|
|
|
- current Oracle licensing spend ~$2M/year (Jorge said "around two million, maybe a bit more")
|
|
- they have 8 processor licenses — BYOL eligible?? need to confirm with Oracle LMS
|
|
- Mike mentioned support renewal coming up in Q2 — leverage point
|
|
- also paying for GoldenGate licenses separately, didn't get the number
|
|
|
|
## App Tier
|
|
|
|
- WebLogic 14c — 6 bare metal servers (BM)
|
|
- running core banking APIs + some internal portals
|
|
- ~~Java 8~~ Java 11 actually, Ana corrected
|
|
- MQ Series for async messaging between services
|
|
- how tightly coupled?? need to dig into this
|
|
- some .NET stuff too but "not critical" per Mike
|
|
|
|
## Peaks & Performance
|
|
|
|
- seasonal peaks — Black Friday is 3x normal traffic
|
|
- "el último Black Friday casi nos tumba" — Jorge
|
|
- need autoscaling story for this
|
|
- end of month batch processing also heavy
|
|
- latency requirements: <50ms for API responses (p99)
|
|
|
|
## Team & Skills
|
|
|
|
- 2 Oracle DBAs — Ana + one other person
|
|
- NO cloud experience, "nunca hemos tocado la nube"
|
|
- will need training / enablement plan
|
|
- Ana seemed nervous about ADB automation — "qué pasa si algo sale mal?"
|
|
- 6 app developers, mostly Java
|
|
- 1 infra person (Mike) who does "everything else"
|
|
|
|
## Timeline & Competition
|
|
|
|
- el CTO quiere migrar en 6 meses ("Jorge: necesitamos estar en cloud antes de julio")
|
|
- aggressive but not impossible if we start in Dec
|
|
- phased approach? non-critical DB first??
|
|
- COMPARING WITH AWS — they got an Aurora pitch last week
|
|
- Jorge: "AWS nos ofreció créditos pero no sé si Aurora aguanta nuestro workload"
|
|
- we need to counter with BYOL savings + Exadata compatibility story
|
|
- also mention: ADB on Exadata = same engine, zero refactoring
|
|
|
|
## Key Concerns (verbatim from Jorge)
|
|
|
|
1. "No quiero downtime en la migración" — zero downtime migration, GG + ADB
|
|
2. "¿Pueden garantizar el mismo performance?" — need benchmarks
|
|
3. Cost — wants to see TCO comparison vs staying on-prem vs AWS
|
|
4. Security — "el regulador nos audita cada trimestre"
|
|
5. What happens to our GoldenGate investment?
|
|
|
|
## My Notes / TODO
|
|
|
|
- [ ] build TCO model: on-prem vs OCI (BYOL) vs AWS (Aurora)
|
|
- [ ] architecture diagram: ADB-S with ADG for HA + cross-region DR
|
|
- [ ] check if MQ Series → OCI Streaming is feasible or if they need to keep MQ
|
|
- [ ] training plan for Ana's team — OCI certs? hands-on workshop?
|
|
- [ ] ~~ask about Kubernetes~~ — Mike confirmed they're interested in OKE
|
|
- [ ] get exact GoldenGate version — need 21c for full ADB integration
|
|
- [ ] PCI compliance mapping — OCI compliance docs
|
|
- [ ] set up reference call with similar banking customer?
|
|
|
|
## Random bits
|
|
|
|
- Jorge keeps mentioning "el board quiere resultados rápidos"
|
|
- they had a failed Azure POC last year — "mala experiencia" — don't bring it up
|
|
- Ana asked about autonomous features — "¿se parchea solo de verdad?"
|
|
she seemed skeptical but interested
|
|
- DR site is 500km away — FastConnect already in both DCs?? need to check
|
|
- budget: Jorge hinted at $1.5M first year target — doable with BYOL
|
