On-premise servers carry many hidden costs — electricity, data center space, hardware maintenance — and the critical risk of a single point of failure. That's why many Thai businesses are now seriously considering moving to the cloud.
But migrating without a solid plan is a recipe for pain. This article presents a practical framework for SMEs that want to migrate safely and cost-effectively.
Why Thai Businesses Are Moving to Cloud in 2026
- No hardware refresh cost — no new server purchases every 3–5 years
- Instant scaling — add resources on demand within minutes
- Small teams can manage more — cloud managed services reduce IT ops burden
- Built-in disaster recovery — automated backup and failover
- Remote work ready — teams can work from anywhere
- Enterprise-grade security — cloud providers invest in security beyond what most businesses can afford independently
The 6 R Framework: How to Think Before You Migrate
Every application in your organization should be evaluated through this framework before deciding what to do with it:
1. Rehost (Lift and Shift)
Move the application from on-premise to a cloud VM without changing the code. Best for: Applications that need to move quickly, or legacy apps that are hard to modify. Trade-off: Fast and easy, but doesn't leverage cloud-native benefits.
2. Replatform
Change some underlying infrastructure, like moving to a managed database service. Example: Moving self-managed MySQL to AWS RDS. Benefit: Reduces maintenance overhead without major code changes.
3. Repurchase
Stop using the current software and switch to SaaS. Example: Replacing an in-house CRM with Salesforce or HubSpot. Best for: Generic applications where SaaS is clearly stronger.
4. Refactor / Re-architect
Rewrite the application as cloud-native (microservices, containers). Best for: Critical applications requiring high scalability or rapid iteration. Trade-off: Highest time and cost investment.
5. Retire
Decommission applications that are no longer being used. Benefit: Reduces portfolio maintenance and cost.
6. Retain
Keep on-premise for now — don't migrate yet. Best for: Applications that can't migrate due to compliance or technical constraints.
Realistic Migration Timeline
| Phase | Duration | Activities |
|---|---|---|
| Discovery & Assessment | 2–4 weeks | Inventory all systems, analyze dependencies, estimate costs |
| Planning & Architecture | 2–4 weeks | Choose cloud provider, design network architecture, security design |
| Pilot Migration | 4–8 weeks | Migrate 1–2 low-risk applications first |
| Core Migration | 2–6 months | Migrate primary applications in waves |
| Optimization | Ongoing | Right-sizing, cost optimization, monitoring setup |
Cloud Security Checklist
Before go-live in cloud, verify all of the following:
- Identity and Access Management (IAM) — principle of least privilege enforced
- Multi-Factor Authentication (MFA) for all privileged accounts
- Network segmentation — VPC, Security Groups, NACLs configured
- Encryption at rest and in transit enabled
- Centralized logging in place (CloudWatch, Azure Monitor)
- Backup policy defined and disaster recovery tested
- Cost alerts configured to trigger when spending exceeds budget
Conclusion
Successful cloud migration is not just "moving a server" — it's reshaping your business's infrastructure strategy for future growth. Adowbig helps plan architecture, execute migration, and optimize cloud costs for Thai businesses. Contact us for a free cloud readiness assessment.
