Cloud Migration Cost Singapore: What SMEs Actually Pay for AWS, Azure & GCP

Ask any vendor about cloud migration costs, and you will get a vague "it depends." This guide cuts through the ambiguity with real numbers — what Singapore SMEs actually pay to move to the cloud, broken down by platform, workload type, and business size.

TL;DR: A typical Singapore SME spends S$5,000-S$30,000 on the migration itself and S$200-S$2,000/month on ongoing cloud costs. AWS is cheapest for startups and web apps. Azure wins for Microsoft-heavy shops. GCP is best for data/AI workloads. The PSG grant covers up to 50% of qualifying cloud solutions. Hidden costs (data transfer, support, training) add 20-40% to published pricing.

What Does Cloud Migration Actually Cost?

Cloud migration costs fall into two buckets: one-time migration costs and ongoing monthly costs. Most SMEs underestimate both.

One-Time Migration Costs

Assessment and planning: S$2,000-S$5,000

• Architecture review and cloud readiness assessment
• Mapping current infrastructure to cloud services
• Data classification and compliance review (PDPA)
• Migration strategy document (lift-and-shift vs re-platform vs re-architect)

Migration execution: S$3,000-S$20,000

• Server migration (per-server cost: S$500-S$2,000 depending on complexity)
• Database migration (S$1,000-S$5,000 per database)
• Application reconfiguration and testing
• DNS cutover and traffic routing
• Post-migration testing and validation

Staff training: S$1,000-S$3,000

• Cloud basics for IT team
• Specific platform training (AWS/Azure/GCP console, monitoring, billing)
• Security best practices in cloud environments

Total one-time cost for a typical SME: S$5,000-S$30,000

Ongoing Monthly Costs

This is where the real long-term expense lies. Here is what Singapore SMEs typically spend:

Micro-SME (1-10 employees, simple web app + email):

• Cloud hosting: S$50-S$150/month
• Managed email (Microsoft 365 or Google Workspace): S$10-S$25/user/month
• Backup and security: S$30-S$80/month
• Total: S$200-S$500/month

Small SME (10-50 employees, web app + database + internal tools):

• Compute (2-5 servers): S$150-S$500/month
• Database (managed RDS/Cloud SQL): S$80-S$300/month
• Storage (S3/Blob/GCS): S$30-S$100/month
• Networking and data transfer: S$50-S$200/month
• Monitoring and security: S$50-S$150/month
• Total: S$500-S$1,500/month

Medium SME (50-200 employees, multiple apps + data warehouse + dev environments):

• Compute (5-20 servers/containers): S$500-S$2,000/month
• Database (multiple instances, read replicas): S$300-S$1,000/month
• Storage and data lake: S$100-S$500/month
• Networking and CDN: S$100-S$500/month
• Monitoring, logging, security: S$150-S$500/month
• Dev/staging environments: S$200-S$800/month
• Total: S$1,500-S$5,000/month

AWS vs Azure vs GCP: Singapore Pricing Compared

All three major cloud providers operate data centres in Singapore (ap-southeast-1 for AWS, Southeast Asia for Azure, asia-southeast1 for GCP). Here is how they compare on the workloads that matter most to SMEs.

Compute (Virtual Machines)

Workload: General-purpose VM, 2 vCPU, 8GB RAM, Linux

• AWS (t3.large): S$0.1152/hour = ~S$83/month (on-demand)
• Azure (B2ms): S$0.1080/hour = ~S$78/month (on-demand)
• GCP (e2-standard-2): S$0.0958/hour = ~S$69/month (on-demand)

With commitment discounts (1-year reserved/committed use):

• AWS Reserved Instance: ~S$52/month (37% savings)
• Azure Reserved VM: ~S$50/month (36% savings)
• GCP Committed Use: ~S$48/month (30% savings)

Winner for compute: GCP — lowest on-demand pricing. AWS and Azure are competitive with reserved instances.

Managed Database (MySQL/PostgreSQL)

Workload: 2 vCPU, 8GB RAM, 100GB storage, single AZ

• AWS RDS (db.t3.large): ~S$120/month
• Azure Database for MySQL (B2ms): ~S$115/month
• GCP Cloud SQL (db-custom-2-8192): ~S$105/month

Winner for managed database: GCP — slightly cheaper. All three are within 15% of each other.

Object Storage (per TB/month)

• AWS S3 Standard: S$0.025/GB = S$25/TB
• Azure Blob Hot: S$0.024/GB = S$24/TB
• GCP Cloud Storage Standard: S$0.023/GB = S$23/TB

Winner for storage: Roughly tied. The difference is negligible for most SME volumes.

Data Transfer Out (to Internet)

This is where costs can surprise you:

• AWS: S$0.12/GB (first 10TB), S$0.085/GB (next 40TB)
• Azure: S$0.12/GB (first 5TB), S$0.087/GB (next 45TB)
• GCP: S$0.12/GB (first 1TB), S$0.11/GB (1-10TB)

Important note: Data transfer INTO all cloud providers is free. Data transfer OUT (serving content to users) is where costs accumulate. A website serving 500GB/month in data transfer pays S$50-S$60/month just for egress.

Cost reduction strategies:

• Use a CDN (CloudFront, Azure CDN, Cloud CDN) — significantly cheaper than direct egress
• Compress assets (images, videos, API responses)
• Cache aggressively at the edge
• For very high egress, GCP's premium tier pricing is competitive

Serverless Functions

Workload: 1 million requests/month, 256MB memory, 200ms average duration

• AWS Lambda: ~S$4.50/month
• Azure Functions: ~S$4.00/month (consumption plan)
• GCP Cloud Functions: ~S$5.20/month

Winner for serverless: Azure — marginally cheaper. All three are very affordable for this workload.

Hidden Costs SMEs Miss

Published pricing accounts for only 60-80% of your actual cloud bill. Watch for these hidden costs:

1. Data Transfer Between Services

Moving data between services within the same cloud provider is not always free. Cross-AZ (Availability Zone) traffic on AWS costs S$0.01/GB each way. For a database-heavy application processing 500GB/month of inter-AZ traffic, that is S$10/month — small, but it adds up across services.

2. Support Plans

All three providers charge extra for responsive technical support:

• AWS Business Support: 10% of monthly bill (minimum S$100/month)
• Azure Standard Support: S$100/month
• GCP Standard Support: S$29/month + 3% of bill
• Free tiers exist but offer only documentation and community forums — not useful for production issues

For SMEs, budget S$100-S$300/month for a support plan. You will need it when something breaks at 2am.

3. Logging and Monitoring

Default monitoring is basic. Production workloads need:

• Log storage: CloudWatch Logs (AWS), Log Analytics (Azure), Cloud Logging (GCP) — S$50-S$200/month for moderate log volumes
• Application Performance Monitoring (APM): Third-party tools like Datadog or New Relic cost S$30-S$80/server/month
• Alert management: PagerDuty or Opsgenie costs S$15-S$30/user/month

Budget S$100-S$500/month for monitoring and logging.

4. Managed Services Premium

Using managed services (managed Kubernetes, managed Redis, managed Elasticsearch) is convenient but costs 30-50% more than self-managed equivalents. Example:

• Self-managed Redis on EC2: ~S$40/month
• AWS ElastiCache (managed Redis): ~S$65/month

The premium is often worth it (less operational burden), but budget for it.

5. Training and Upskilling

Your team needs to learn the new platform. Budget:

• Online courses (AWS/Azure/GCP certifications): S$500-S$1,500 per person
• Hands-on workshops: S$2,000-S$5,000 per team
• Learning curve productivity loss: 2-4 weeks per team member

PSG Grant for Cloud Migration

PSG + Cloud Migration Budget Example

Scenario: Small SME migrating email, file storage, and a web application to the cloud.

• Microsoft 365 Business (10 users, 1 year): S$3,600
• Cloud hosting setup and migration: S$8,000
• Training: S$2,000
• Total cost: S$13,600
• PSG grant (50%): -S$6,800
• Your cost: S$6,800

Step-by-Step Budgeting Guide

Step 1: Audit Current Infrastructure

Document everything you currently run:

• Number and specification of servers (physical or virtual)
• Database types and sizes
• Storage volumes and growth rate
• Network bandwidth usage
• Software licences that may change
• Monthly costs of current setup (hosting, maintenance, licences)

Step 2: Map to Cloud Equivalents

For each component, find the cloud equivalent:

• Physical server → EC2/VM/Compute Engine instance
• On-premises database → RDS/Azure SQL/Cloud SQL
• File server → S3/Blob Storage/GCS
• Email server → Microsoft 365/Google Workspace
• VPN → Cloud VPN/DirectConnect

Step 3: Use Cloud Pricing Calculators

All three providers offer detailed pricing calculators:

• AWS Pricing Calculator: calculator.aws
• Azure Pricing Calculator: azure.microsoft.com/en-us/pricing/calculator
• GCP Pricing Calculator: cloud.google.com/products/calculator

Input your mapped workloads and get monthly cost estimates. Add 20-30% buffer for hidden costs.

Step 4: Factor in Migration Costs

Add the one-time costs:

• Assessment/planning: S$2,000-S$5,000
• Migration execution: S$3,000-S$20,000
• Training: S$1,000-S$3,000
• Testing and validation: S$1,000-S$3,000

Step 5: Calculate Total First-Year Cost

First-year cost = One-time migration costs + (Monthly cloud cost x 12) - PSG grant

Example:

• Migration: S$10,000
• Monthly cloud: S$800 x 12 = S$9,600
• PSG grant: -S$5,000
• First-year total: S$14,600
• Subsequent years: S$9,600/year (ongoing cloud costs only)

Compare this to your current infrastructure cost. For most SMEs, cloud becomes cheaper within 12-18 months when you factor in reduced maintenance, eliminated hardware refresh cycles, and improved scalability.

Which Cloud Platform Should You Choose?

Choose AWS If:

• You are a startup or tech company
• You need the widest range of services
• Your team has AWS experience
• You want the largest community and most third-party integrations
• You need advanced AI/ML services (SageMaker, Bedrock)

Choose Azure If:

• Your business runs on Microsoft (Office 365, Active Directory, Teams)
• You need hybrid cloud (on-premises + cloud)
• Your industry is financial services, government, or healthcare (Azure has the most compliance certifications)
• You use .NET or SQL Server
• Your team knows Windows server administration

Choose GCP If:

• You are data-heavy (analytics, BigQuery, AI/ML)
• You want the best Kubernetes experience (GKE)
• Your team uses open-source tools extensively
• You want the simplest, most developer-friendly interface
• You need strong AI/ML capabilities at the best price

For Most Singapore SMEs:

AWS is the safest default choice — widest ecosystem, most local talent, most resources. Azure is the best choice if you are already invested in the Microsoft ecosystem. GCP is excellent for data-driven businesses but has a smaller local ecosystem.

Frequently Asked Questions

How long does cloud migration take for an SME?

A basic migration (email, file storage, simple web app) takes 2-4 weeks. A complex migration (multiple applications, databases, custom integrations) takes 2-3 months. Larger enterprises with legacy systems may need 6-12 months.

Will my cloud costs increase over time?

Cloud costs typically increase 10-15% annually due to growing data volumes, additional services, and increased usage. However, cloud providers regularly reduce per-unit pricing. Right-sizing (adjusting instance sizes to actual usage) and reserved instances can offset growth. Budget for 10% annual increase.

Is it cheaper to stay on-premises?

For SMEs with fewer than 50 employees, cloud is almost always cheaper when you account for hardware depreciation, electricity, cooling, physical security, maintenance staff, and disaster recovery infrastructure. The break-even point is typically around 100-200 servers where on-premises may be cheaper for stable workloads.

Can I migrate back if cloud does not work out?

Yes, but reverse migration (cloud to on-premises) is expensive and time-consuming — typically more costly than the initial migration. The main costs are data egress charges, new hardware procurement, and re-architecture. This is called "cloud lock-in." Mitigate it by using open standards, containerisation (Docker/Kubernetes), and avoiding proprietary managed services where possible.
