6.4 Cloud Case Studies

By · Reviewed & last updated · Part of Enterprise Architecture Tutorial

Cloud is no longer a future bet for Philippine enterprises - banks, telcos, government and SMEs are deeply mid-migration. This lesson collects representative cases and the architecture patterns they expose.

Representative PH Cloud Use Cases

SectorWorkloadCloud Pattern
Banking (BSP-regulated)Core banking data feeds, digital channelsHybrid: core on-prem, channels on cloud, dedicated link
TelcoCustomer self-service, billing analyticsMulti-region cloud, data warehouse + ML
Government (DICT GovCloud)Citizen services, ePhilHealth, SSSSovereign cloud, on-shore data, gov data centre tie-in
RetailE-commerce + POS syncMostly cloud, edge POS with offline cache
BPOVoice + screen recording, workforce mgmtCloud contact centre (Genesys/Five9), recording in S3/Blob
HealthcareTelemedicine, EMRPrivate cloud or on-shore region for Data Privacy Act compliance
LogisticsReal-time tracking, route optimizationEvent streams + serverless geo lookups

Three Architecture Patterns That Recur

PatternWhen To PickKey Trade-Off
Lift-and-shiftTime pressure, datacentre exitCheap to move, expensive to run if not optimised
Re-platform (managed services)Modernising auth, DB, queueLower ops cost, some vendor lock-in
Re-architect (cloud-native)Greenfield product, scale mattersBest long-term unit economics, highest upfront effort

Common Pitfalls Seen Locally

  1. Underestimating egress charges from cloud back to on-prem core systems.
  2. Forgetting BSP Circular 982 and DPA compliance attestation early in the project.
  3. Skipping latency tests for users on prepaid mobile networks.
  4. Treating multi-cloud as resilience when it actually doubles operational complexity.
  5. Ignoring Manila power outages - cloud is great until the office router goes dark.
