Why the AWS vs Azure Decision Matters More in India Than Elsewhere
Both AWS and Azure have data centres in India — AWS in Mumbai and Hyderabad, Azure in Pune (Central India), Chennai (South India), and Mumbai (West India). The proximity of Azure's South India region in Chennai makes a latency difference for applications serving Kerala users, particularly anything requiring sub-100ms response times like payment processing or real-time chat.
This comparison is based on actual workloads from Kerala businesses I've migrated to cloud, not theoretical pricing calculators. The numbers will differ from what you see on vendor websites because real usage includes data transfer costs, snapshot storage, and load balancer fees that the calculators often underestimate.
Scenario 1 — A Kerala E-commerce Store (50K Monthly Visitors)
AWS configuration
1x t3.medium EC2 (2 vCPU, 4 GB RAM) in Mumbai region: ₹3,400/month on-demand, ₹1,900/month on 1-year reserved. RDS MySQL db.t3.micro: ₹2,100/month. S3 storage 100 GB: ₹190/month. CloudFront CDN (200 GB transfer): ₹1,400/month. Total AWS: approximately ₹5,590/month (reserved) to ₹7,090/month (on-demand).
Azure configuration
1x B2s VM in South India (2 vCPU, 4 GB RAM): ₹3,100/month pay-as-you-go, ₹1,850/month reserved. Azure Database for MySQL Flexible Server Burstable B2ms: ₹2,400/month. Blob Storage 100 GB: ₹160/month. Azure CDN 200 GB: ₹1,200/month. Total Azure: approximately ₹5,610/month (reserved) to ₹6,860/month (pay-as-you-go).
Verdict for e-commerce
Near price parity. Azure has a marginal cost advantage on CDN and blob storage. AWS has better ecosystem integration if you use other AWS services. Decision driver: your developer team's existing skills.
Scenario 2 — A Kerala SaaS Startup (API Backend, 500 Active Users)
AWS configuration
2x t3.small EC2 behind Application Load Balancer: ₹4,200/month reserved. RDS PostgreSQL db.t3.small Multi-AZ: ₹7,800/month. ElastiCache t3.micro: ₹1,600/month. Total: approximately ₹13,600–₹16,400/month.
Azure configuration
2x B1ms VMs + Azure Load Balancer: ₹3,900/month. Azure Database for PostgreSQL Flexible Server: ₹7,200/month. Azure Cache for Redis C0: ₹1,400/month. Total: approximately ₹12,500–₹15,000/month.
Verdict for SaaS
Azure is 8–10% cheaper for this typical SaaS pattern in Indian regions. The difference grows as you scale. Azure's SQL MI and Cosmos DB also provide strong managed database options if you're building multi-region products.
Hidden Costs That Kill Kerala Cloud Budgets
- Data transfer OUT — both providers charge for outbound data. AWS charges ₹6.7/GB after 100 GB free; Azure charges ₹6.4/GB. For data-heavy applications (video, large file transfers), this becomes significant
- Snapshots and backups — EBS snapshots on AWS and Managed Disk snapshots on Azure are charged per GB. A 100 GB disk with daily snapshots retained for 30 days can add ₹1,500–₹2,500/month you didn't budget for
- NAT Gateway — both providers charge for NAT Gateway usage, typically ₹3–₹4/GB. Applications that route internal traffic through NAT see surprising bills
- Support plans — AWS Business Support starts at $100/month (₹8,300). Azure Developer Support is ₹1,250/month. Factor this in if you need SLA-backed support
When AWS Makes More Sense for a Kerala Business
- Your team already has AWS certifications or experience
- You need a specific AWS service with no Azure equivalent (SageMaker, Lambda@Edge, AWS Rekognition)
- Your product is targeting international markets where AWS has more global regions
- You need AWS Marketplace integrations
- You are building on top of other AWS-native services (Cognito, Pinpoint, SES)
When Azure Makes More Sense for a Kerala Business
- You already use Microsoft 365 or Active Directory — Azure AD integration is seamless and often reduces licensing costs
- Your development team uses .NET or C# — Azure tooling for Microsoft stacks is superior
- You need HIPAA or healthcare compliance — Azure has strong certifications for Indian healthcare
- You are a government-adjacent organisation — Microsoft has MeitY-empanelled cloud status in India
- Your primary database is SQL Server — Azure SQL MI eliminates licensing complexity
Frequently Asked Questions
Which cloud provider is cheaper for a small Kerala business running a basic website and database?
For a basic setup — one application server and one managed database — AWS and Azure are within 5–10% of each other in Indian regions. The real cost differences emerge at scale, when you factor in data transfer, managed services, and reserved instance commitments. For most Kerala SMEs spending under ₹15,000/month on cloud, the deciding factor should be developer familiarity, not raw pricing.
Does DPDP Act compliance affect which cloud provider a Kerala business should choose?
Both AWS and Azure offer DPDP-compliant data residency options in Indian data centres. AWS Mumbai and Hyderabad regions and Azure's Central India, South India, and West India regions all store data within Indian boundaries. The key requirement is that you explicitly configure your services to use these regions and don't enable global data replication without understanding where data lands.
Can a Kerala startup start on AWS free tier and migrate to Azure later?
Yes, but migrations between cloud providers are not trivial. The free tier on both AWS and Azure covers most startup needs for the first 12 months. If you start on AWS free tier and later discover Azure is more cost-effective for your workload, a migration typically takes 2–6 weeks of engineering work. It is worth deciding your long-term platform preference before you accumulate significant infrastructure, rather than optimising later.
