Cloud Migration Cost in India
Detailed cost guide for migrating to AWS, Azure, and Google Cloud | Brainguru Technologies Pvt Ltd, Noida, India
Cloud migration has become a strategic imperative for Indian businesses seeking agility, scalability, and cost efficiency. The Indian cloud computing market is projected to exceed 1.3 lakh crore rupees by 2027, driven by digital transformation initiatives across enterprises, startups, and government organisations. Yet one of the most common questions businesses ask before beginning their cloud journey is deceptively simple: how much will it cost?
The answer depends on numerous factors including the number and complexity of workloads, the migration strategy chosen, the target cloud platform, and the level of optimisation applied post-migration. At Brainguru Technologies Pvt Ltd, based in Noida, India, we have executed over 100 cloud migration projects for businesses ranging from 5-person startups to enterprises with 500+ employees. This guide provides transparent cost breakdowns based on our real project data to help you budget accurately for your cloud migration.
Cloud Migration Cost by Complexity
Simple Migration: ₹2 Lakh to ₹8 Lakh

What falls in this category:
- One to five applications or workloads
- Single web application with database migration
- Email and collaboration migration to cloud-based services
- Static website migration to cloud hosting with CDN
- Small database migration under 100 GB

- Documentation, training, and handover: ₹50,000 to ₹1,50,000
Typical timeline: 6 to 16 weeks
Monthly cloud infrastructure cost after migration: ₹30,000 to ₹2,50,000 depending on workload characteristics.
Complex Migration: ₹25 Lakh to ₹80 Lakh+
Complex migrations involve large-scale enterprise environments with numerous applications, substantial data volumes, strict compliance requirements, and the need for significant architectural transformation. These projects require detailed planning, phased execution, and close coordination across multiple teams.
What falls in this category:
- Twenty or more applications with complex interdependencies
- Enterprise applications including ERP, CRM, and legacy systems
- Database migration involving multiple terabytes of data
- Application modernisation and refactoring for cloud-native architecture
- Multi-region deployment for disaster recovery and global performance
- Compliance requirements including HIPAA, PCI DSS, SOC 2, or RBI guidelines
- Hybrid cloud architecture with on-premises and cloud components
- Container orchestration and microservices migration
Cost breakdown:
- Comprehensive assessment and discovery: ₹2,00,000 to ₹5,00,000
- Architecture design and proof of concept: ₹3,00,000 to ₹8,00,000
- Migration execution (phased): ₹10,00,000 to ₹35,00,000
- Application modernisation: ₹5,00,000 to ₹15,00,000
- Security and compliance implementation: ₹2,00,000 to ₹8,00,000
- Testing and validation: ₹2,00,000 to ₹5,00,000
- Post-migration optimisation and FinOps: ₹1,50,000 to ₹4,00,000
- Documentation, training, and knowledge transfer: ₹1,00,000 to ₹3,00,000
Typical timeline: 16 to 52 weeks (phased execution)
Monthly cloud infrastructure cost after migration: ₹1,50,000 to ₹15,00,000+ depending on scale and architecture.
Factors That Influence Cloud Migration Cost
- Number of workloads: Each application or workload requires individual assessment, migration planning, execution, and testing. More workloads mean higher costs, though economies of scale apply to large migrations.
- Data volume: Large databases require more time for migration, testing, and validation. Data transfer costs from cloud providers also increase with volume, though most providers offer free or discounted ingress.
- Migration strategy: Rehosting or lift and shift is the cheapest approach. Replatforming involves moderate additional cost for optimisation. Refactoring or re-architecting for cloud-native is the most expensive but delivers the greatest long-term benefits.
- Application complexity: Modern web applications are generally easier and cheaper to migrate than legacy applications built on older technologies, monolithic architectures, or proprietary platforms.
- Downtime tolerance: Migrations that require zero downtime need more sophisticated approaches including blue-green deployment, database replication, and traffic switching, which increase costs. Workloads that can tolerate scheduled maintenance windows are cheaper to migrate.
- Compliance requirements: Industries with regulatory requirements need additional security controls, audit trails, encryption, and compliance documentation, adding 20 to 40 percent to migration costs.
- Target platform: AWS, Azure, and GCP have different pricing structures and service capabilities. The platform choice affects both migration costs and ongoing operational costs.
- Existing technical debt: Applications with poor documentation, outdated dependencies, or fragile architectures require more assessment and remediation effort before migration.
Cloud Migration Strategies
The migration strategy you choose for each workload significantly impacts both cost and outcome. Here are the primary strategies and when to use each.
| Strategy | Description | Cost Level | Best For |
|---|---|---|---|
| Rehost (Lift and Shift) | Move applications as-is to cloud infrastructure | Low | Quick migration, minimal risk |
| Replatform (Lift and Optimise) | Make targeted optimisations during migration | Medium | Balance of speed and optimisation |
| Refactor (Re-architect) | Redesign for cloud-native architecture | High | Maximum scalability and efficiency |
| Repurchase | Replace with SaaS alternative | Variable | Commodity applications |
| Retire | Decommission applications no longer needed | Minimal | Redundant or unused applications |
| Retain | Keep on-premises for now | None | Applications with specific on-prem requirements |
At Brainguru Technologies, we typically recommend a mixed strategy where each workload is assessed individually. In a typical migration engagement, 40 to 50 percent of workloads are rehosted, 25 to 30 percent are replatformed, 10 to 15 percent are refactored, and the remainder are repurchased, retired, or retained. This balanced approach optimises the trade-off between migration speed, cost, and long-term cloud efficiency.
Hidden Costs to Plan For
- Data egress charges: Cloud providers charge for data leaving their network. While ingress is typically free, egress costs can add up for applications that serve large amounts of data to users or other systems.
- Training and change management: Your team needs training on cloud operations, monitoring, and incident response. Budget 1 to 3 lakh rupees for comprehensive training programmes.
- Temporary parallel running costs: During migration, you may need to run both on-premises and cloud environments simultaneously, doubling infrastructure costs for a period of weeks to months.
- License adjustments: Some software licences need to be converted or replaced for cloud use. Microsoft and Oracle licences in particular can have complex cloud licensing implications.
- Network connectivity: Hybrid cloud configurations may require dedicated network connections like AWS Direct Connect or Azure ExpressRoute, adding monthly connectivity costs.
- Post-migration optimisation: Initial cloud configurations are rarely optimal. Budget for three to six months of post-migration optimisation to right-size resources and eliminate waste.
