⚡ QUICK ANSWER: What is cloud migration?

Cloud migration is the process of moving digital assets—data, applications, and IT resources—from on-premises infrastructure to cloud platforms (AWS, Azure, GCP). For Southeast Asian enterprises in 2026, this typically involves: (1) assessment of current infrastructure, (2) choosing between public, private, or hybrid cloud, (3) data migration with compliance considerations (PDPA, local data residency), (4) application modernization, and (5) ongoing optimization. Average migration timelines range from 6-18 months depending on complexity, with ROI typically realized within 2-3 years.

01 // WHY MIGRATE

Why Southeast Asian Enterprises Are Moving to Cloud

The digital transformation wave across ASEAN is driving unprecedented cloud adoption.

💰

Cost Optimization

Reduce CapEx by 40-60% by eliminating on-premises hardware. Pay only for what you use with cloud's consumption-based model.

🚀

Scalability

Scale instantly to meet demand. Critical for e-commerce peaks during 9.9, 11.11, and holiday seasons across SEA.

🌏

Regional Presence

AWS, Azure, and GCP now have data centers in Singapore, Jakarta, and expanding across the region.

🔒

Enhanced Security

Enterprise-grade security that most organizations cannot achieve on-premises. SOC2, ISO 27001 certified infrastructure.

The Southeast Asian Cloud Opportunity

Southeast Asia represents one of the fastest-growing cloud markets globally. With a combined GDP of over $3.6 trillion and a population of 680 million, the region's digital economy is projected to reach $330 billion by 2025.

Key drivers for cloud migration in the region include:

  • Digital-first consumers: SEA has 460 million internet users, with mobile-first behavior driving demand for always-on services
  • Government digitalization initiatives: Vietnam's National Digital Transformation Program, Singapore's Smart Nation, Thailand 4.0
  • Startup ecosystem growth: Over 3,000 tech startups, many cloud-native from inception
  • Manufacturing modernization: Industry 4.0 adoption requiring cloud-based IoT and analytics
02 // CLOUD PROVIDERS

AWS vs Azure vs Google Cloud in Southeast Asia

Each major cloud provider has unique strengths for the ASEAN market.

Feature AWS Azure Google Cloud
SEA Data Centers Singapore, Jakarta, Bangkok (planned) Singapore, Jakarta, Malaysia Singapore, Jakarta
Vietnam Presence CloudFront PoPs, Direct Connect Azure CDN, ExpressRoute Cloud CDN, Interconnect
Latency to Hanoi ~25ms from Singapore ~28ms from Singapore ~26ms from Singapore
Enterprise Strength Broadest service catalog Microsoft ecosystem integration Data/AI/ML leadership
Local Support Vietnamese language support Local partner network Growing local presence
Pricing (Vietnam) $$$ (Premium) $$ (Competitive) $$ (Aggressive discounts)

Choosing the Right Provider

Your choice should depend on several factors specific to your organization:

  • Existing ecosystem: Heavy Microsoft users should consider Azure for seamless integration
  • AI/ML requirements: Google Cloud leads in data analytics and machine learning tools
  • Service breadth: AWS offers the most comprehensive service catalog
  • Cost sensitivity: All providers offer committed use discounts; GCP often most aggressive
  • Data residency: Check which provider has data centers meeting your compliance needs
03 // MIGRATION STRATEGIES

The 6 R's of Cloud Migration

Choose the right approach for each workload based on business requirements.

🔄

Rehost (Lift & Shift)

Move applications as-is to cloud. Fastest approach with minimal changes. Good for legacy apps with limited optimization potential.

🔧

Replatform

Make minor optimizations during migration. Example: moving to managed database services while keeping application logic.

🏗️

Refactor / Re-architect

Redesign applications to be cloud-native. Highest effort but maximum cloud benefits. Consider for strategic applications.

🛒

Repurchase

Replace with SaaS alternative. Example: Move from on-prem CRM to Salesforce, or ERP to cloud-native solution.

🔐

Retain

Keep on-premises for now. Some workloads may have compliance, latency, or cost reasons to stay on-prem temporarily.

🗑️

Retire

Decommission unused applications. Cloud migration is a good opportunity to eliminate technical debt.

04 // REGIONAL COMPLIANCE

Navigating SEA Data Regulations

Understanding data residency and privacy requirements across ASEAN nations.

Country Key Regulation Data Residency Notes
Vietnam Cybersecurity Law, Decree 13 Local storage for certain data types Personal data of Vietnamese users must be stored locally
Singapore PDPA No strict requirement Must ensure adequate protection if data transferred overseas
Indonesia GR 71, PDP Law Public sector data must be local Private sector has flexibility with safeguards
Thailand PDPA (Thailand) No strict requirement Cross-border transfers allowed with adequate protection
Malaysia PDPA 2010 Ministerial approval for transfers Sensitive data has additional restrictions
05 // MIGRATION TIMELINE

Typical Enterprise Migration Timeline

A phased approach ensures minimal disruption to business operations.

PHASE 1 • WEEKS 1-4
Discovery & Assessment
Inventory all applications, dependencies, and data. Assess cloud readiness. Define migration priorities based on business value and complexity.
PHASE 2 • WEEKS 5-8
Architecture & Planning
Design target cloud architecture. Select migration strategies for each workload. Create detailed migration runbooks. Establish security and compliance frameworks.
PHASE 3 • WEEKS 9-16
Foundation & Pilot
Build cloud landing zone. Set up networking, identity, and security controls. Migrate pilot workloads. Validate performance and security.
PHASE 4 • WEEKS 17-36
Migration Waves
Execute migration in planned waves. Each wave includes pre-migration testing, cutover, and validation. Typically 3-5 waves for enterprise migrations.
PHASE 5 • ONGOING
Optimization & Operations
Continuous optimization of cloud resources. Implement FinOps practices. Ongoing security monitoring. Regular architecture reviews.
06 // COSTS & ROI

Understanding Migration Economics

A clear picture of costs and expected returns.

Typical Cost Breakdown

Enterprise cloud migration costs vary based on complexity, but here's a typical breakdown:

  • Assessment & Planning: 5-10% of total budget
  • Migration Execution: 30-40% of total budget
  • Testing & Validation: 15-20% of total budget
  • Training & Change Management: 10-15% of total budget
  • Contingency: 15-20% recommended buffer

Expected ROI

Based on our experience with SEA enterprises:

  • Infrastructure cost reduction: 25-40% within 2 years
