Migrating from AWS: How to Cut Cloud Costs by 30–60% Without Losing Reliability

Amazon Web Services (AWS) remains the world’s most mature and feature-rich public cloud platform, offering over 200 services — from virtual machines to advanced AI and analytics tools. However, as companies scale and their cloud footprints grow, one trend becomes clear: costs rise faster than value.
Let’s look at why more and more businesses are choosing to move away from AWS.
1
Rising Costs and Billing Complexity
AWS pricing is notoriously complex. Hundreds of instance types, multiple database licensing models, layered storage tiers, data transfer fees, and per-operation billing make financial forecasting extremely difficult.
According to Gartner, 30–40% of AWS spending comes from unused or misconfigured resources due to this opacity.
Vendor Lock-In
Many companies start with AWS for convenience, only to find themselves dependent on proprietary services years later — for example:
  • DynamoDB → difficult to migrate without redesigning applications
  • Lambda + API Gateway → unique operational constraints
  • Glue / Athena / Kinesis → no direct cross-cloud equivalents
This “lock-in” makes companies less flexible and increases long-term risk.
High Data Egress Costs
AWS data-out (egress) pricing is among the highest in the industry.
For data-intensive workloads, 10–20% of total spend may be purely outbound traffic fees.
Company X was paying ~$28,000/month for AWS infrastructure.
After migrating to Google Cloud, costs dropped to $19,600/month (−30%) — while reliability and performance actually improved.
Case Example
Goal of This Article
This guide shows:
  • where AWS costs actually come from,
  • which platforms offer better value,
  • how to plan and execute a migration,
  • what financial impact to expect,
  • how to manage risks,
  • and how to achieve 30–60% total cost reduction.

Assessing Your Current AWS Infrastructure
Before any migration, you need a comprehensive audit.
The biggest mistake companies make is “lift-and-shift” migration — moving workloads as-is.
That approach transfers inefficiencies and delivers limited savings.
AWS Cost Distribution
According to AWS Cost Explorer and FinOps Foundation data, typical AWS cost breakdowns look like this:
  • EC2 (Compute): 35–45%
  • S3 (Storage): 15–25%
  • RDS (Databases): 20–30%
  • Others (Traffic, CloudWatch, Lambda): 10–20%
Thus, the main optimization targets are compute and databases.
Example: Compute

Savings: up to 60%
In real workloads:
  • 20–30% of instances are underutilized (CPU < 20%),
  • many are overprovisioned,
  • others run 24/7 unnecessarily.
Example: Storage (S3)
Common waste sources:
  • Using S3 Standard instead of Infrequent Access,
  • No lifecycle policies,
  • Excessive GET/LIST operations,
  • Costly cross-region replication.
Example: Databases (RDS)
RDS is one of the most expensive AWS services, due to:
  • license costs,
  • backup and storage fees,
  • high IOPS pricing (especially Provisioned IOPS).
  • Migrating RDS PostgreSQL to Cloud SQL, Azure Database, or a self-managed PostgreSQL often saves 20–50%.

Choosing a Target Platform and Comparing Costs
Migration is not just a technical move — it’s a financial and strategic decision.
Let’s compare the leading alternatives.

Real Example
A company with 20 medium-size servers was paying ~$1,400/month on AWS.
After migrating to Hetzner, the bill dropped to $560/month
over $10,000 annual savings.

Summary
Compute + storage + data transfer optimization yields up to 60% savings overall.

Migration Planning and Budgeting
Migration should be managed as a structured project.
1. Technical Assessment
Architecture mapping
  • Dependency analysis
  • Network planning
  • Load testing
  • CI/CD integration review
2. Financial Analysis
Current cloud spend
  • Potential savings
  • Migration cost estimate
  • ROI forecast
3. Migration Plan
Wave-based migration
  • Separate dev/stage/prod environments
  • Rollback strategy
  • Testing and monitoring

Preparation and Tooling
Preparation defines success.
Professional teams use Infrastructure as Code and migration automation tools.
  • Key ToolsTerraform → infrastructure definition
  • Ansible → server configuration
  • AWS DMS / pg_dump → database migration
  • rclone / gsutil / rsync → data transfer
  • Kubernetes + Helm → workload portability
  • Grafana + Prometheus → observability
Example
Migration of a 200GB PostgreSQL RDS to Cloud SQL:
Duration: 6 hours
Data transfer cost: ~$50
Old cost: $220/month → new cost: $150/month
Annual saving: $840 per DB

Migration Process
Typical migration flow:
1. Deploy New Infrastructure
Create:
  • networks/subnets,
  • VMs or Kubernetes clusters,
  • storage,
  • CI/CD pipelines.
2. Data Replication
  • rsync for files,
  • DMS for databases,
  • rclone/gsutil for objects.
3. Data Synchronization
Use:
  • logical replication,
  • queue mirroring,
  • real-time sync for minimal downtime.
4. Blue-Green Deployment
Run two environments:
  • Blue = existing AWS
  • Green = new cloud
  • Switch traffic once validation passes.
5. Phased Rollout
Start with:
  • Dev → Staging → Non-critical production
  • Then migrate core workloads.
Example:
One company migrated dev/stage to GCP, keeping prod on AWS.
They reduced total cloud spend by 40% with minimal risk.
7
Post-Migration Optimization
The real savings begin after migration.
Compute Optimization
  • Downsize underused VMs
  • Use auto-scheduling to stop idle nodes
  • Apply autoscaling policies
Storage Optimization
  • Apply lifecycle management
  • Move cold data to archive tiers
  • Clean up duplicates
Database Optimization
  • Use serverless or managed DBs
  • Tune vacuum/IO parameters
  • Add read replicas
Discount Programs
  • GCP Committed Use Discounts: up to −57%
  • Azure Reserved Instances: up to −40%
  • Hetzner: already low base rates
Example
After right-sizing, one company reduced 30% of VM resources, saving an additional 15%, reaching 45% total savings from AWS costs.

Risks and Mitigation Strategies
1. Data Egress Fees
Outbound data from AWS is expensive.
Mitigation:
  • plan staged transfers,
  • compress and archive old data,
  • prioritize in-region movement.
2. IAM Differences
AWS IAM roles don’t directly translate to other platforms.
Mitigation:
  • rebuild role structures,
  • apply least-privilege policies.
3. API Incompatibility
Some AWS services have no direct equivalents.
Mitigation:
  • replace with open-source tools,
  • adopt Kubernetes-native solutions.
4. Architectural Differences
Apps may need minor redesigns.
Mitigation:
  • sandbox testing,
  • pilot migrations,
  • detailed rollback planning.
5. Organizational Risks
Team readiness and process maturity matter.
Mitigation:
  • clear communication plan,
  • DevOps training and documentation.

Conclusion
Migrating from AWS is not merely a cost-cutting move — it’s a strategic transformation.
It brings financial control, architectural independence, and operational transparency.

Based on multiple real-world cases:
  • companies save 20–60%,
  • improve reliability and scalability,
  • regain ownership of their infrastructure,
  • and reduce lock-in risk.
To maximize results:
  1. Audit your AWS usage,
  2. Choose the right target platform,
  3. Execute a phased migration,
  4. Optimize continuously afterward.
A well-planned AWS migration can save tens or hundreds of thousands of dollars per year, without sacrificing performance or stability — while giving your company the flexibility and control it deserves.
