While everyone starts with local AI development, few engineers have a clear strategy for when and how to move to cloud production. Through migrating AI systems from laptop to scale, I’ve learned that the transition isn’t just about infrastructure, it’s about rethinking your entire approach to AI development.

Most developers either migrate too early (wasting money and complexity) or too late (scrambling when local systems can’t handle demand). This guide helps you identify the right time to migrate and execute the transition successfully.

When to Consider Cloud Migration

Local development has limits. Recognize when you’re hitting them:

Signs You’ve Outgrown Local

Consistent resource constraints. If your laptop fans run constantly during AI operations, you’re CPU/GPU bound. Cloud offers more power.

Collaboration friction. When “it works on my machine” becomes a constant refrain, shared cloud infrastructure solves the problem.

Availability requirements. Users expect 24/7 availability. Your laptop can’t provide that.

Scale demands. If you’re queuing requests locally because you can’t process them fast enough, it’s time to scale.

Security requirements. Sensitive data needs proper infrastructure. Your laptop doesn’t have enterprise security controls.

For local development patterns, see my guide on local LLM setup.

Signs You Should Stay Local Longer

Rapid iteration phase. If you’re changing architecture daily, cloud deployment adds friction. Stay local until designs stabilize.

Limited users. A handful of internal users might not justify cloud costs and complexity.

Budget constraints. Cloud costs are real. If you’re bootstrapping, local development preserves runway.

Learning and experimentation. When you’re still figuring out what works, local iteration is faster and cheaper.

Migration Planning

A successful migration requires planning:

Architecture Assessment

Document current architecture. What services exist? How do they communicate? What are the dependencies?

Identify cloud-native changes. Local patterns don’t always translate. Direct file access becomes object storage. Local caching becomes Redis.

Plan for statelessness. Cloud services should be stateless. Where does state currently live? How will it move?

Consider multi-region. If you need global reach, plan for multi-region from the start.

Cost Modeling

Estimate cloud costs. Compute, storage, bandwidth, AI API calls: model your expected spend.

Compare to local costs. Your time has value. Local ops overhead might cost more than cloud services.

Plan for variability. Cloud costs scale with usage. Model low, expected, and high scenarios.

Identify cost optimization opportunities. Reserved instances, spot instances, tiered storage: plan these from the start.

Migration Phases

Don’t migrate everything at once. Phase the migration to manage risk.

Start with non-critical services. Migrate less important components first. Build experience before touching production.

Plan rollback at each phase. If something goes wrong, you need to recover quickly.

Document and learn. Each phase teaches you something. Apply learnings to subsequent phases.

Infrastructure Choices

Selecting the right cloud infrastructure:

Compute Options

Managed containers (ECS, Cloud Run, Azure Container Apps). Easier operations, less control. Good default choice for most AI applications.

Kubernetes. Maximum flexibility, significant complexity. Only choose if you need advanced orchestration.

Serverless functions. Great for event-driven and bursty workloads. Timeout limits can be problematic for AI operations.

Virtual machines. Full control, most operational overhead. Usually only needed for specific requirements.

AI Service Options

Managed AI APIs. OpenAI, Anthropic, Google: easiest to migrate to, simplest operations.

Cloud AI platforms. AWS Bedrock, Azure OpenAI, Google Vertex: similar APIs with cloud integration benefits.

Self-hosted models. Most control, most complexity. Only if you have specific requirements (privacy, customization, cost at scale).

For infrastructure decision frameworks, see my guide on AI infrastructure decisions.

Data and Storage

Vector databases. Pinecone, Weaviate Cloud, or managed PostgreSQL with pgvector. Match to your scale and query patterns.

Object storage. S3, GCS, or Azure Blob for documents, models, and large artifacts.

Caching layer. Managed Redis (ElastiCache, Memorystore) for performance-critical caching.

Relational database. RDS, Cloud SQL, or Azure SQL for structured data that needs transactions.

Executing the Migration

Practical steps for a smooth transition:

Environment Setup

Infrastructure as code. Define your cloud resources in Terraform, Pulumi, or CloudFormation. Reproducibility is essential.

Environment parity. Development, staging, and production should be as similar as possible.

Secrets management. Move from local environment variables to proper secrets management. Consider AWS Secrets Manager or HashiCorp Vault.

Networking configuration. VPCs, security groups, private endpoints: secure your infrastructure from the start.

Application Changes

Configuration externalization. All environment-specific config from external sources (environment variables, config services).

Logging standardization. Structured logging that works with cloud log aggregation.

Health checks and metrics. Cloud platforms need health signals. Implement proper endpoints.

Graceful shutdown. Cloud services get terminated. Handle shutdown signals properly.

Data Migration

Vector store migration. Export embeddings and metadata from local stores. Import to cloud vector database.

Document migration. Move documents to object storage. Update references throughout the application.

Database migration. Schema creation, data transfer, validation. Plan for the cutover carefully.

Testing data integrity. After migration, verify data is complete and correct. Don’t skip this.

For deployment patterns, see my guide on deploying AI with Docker and FastAPI.

Traffic Cutover

DNS-based cutover. Point your domain to cloud infrastructure. Fastest rollback if problems occur.

Gradual traffic shift. Use load balancers to shift traffic percentage gradually.

Feature flags for new code paths. If migration involves code changes, gate them with flags.

Monitoring during cutover. Watch metrics closely. Be ready to roll back.

Common Migration Challenges

Anticipate these issues:

Performance Differences

Network latency. Local calls are nearly instant. Network calls add latency. Plan for this.

Cold starts. Serverless and container services have cold starts. Pre-warm for latency-sensitive operations.

Resource contention. Cloud resources are shared. Performance can vary more than local.

Scaling delays. Auto-scaling isn’t instant. Handle traffic spikes gracefully.

Cost Surprises

Egress charges. Data leaving the cloud costs money. Optimize data transfer patterns.

Logging costs. Verbose logging gets expensive fast. Set appropriate log levels.

AI API costs at scale. Local testing doesn’t reveal true API costs. Monitor closely after migration.

Idle resources. Cloud resources that sit unused still cost money. Implement proper scaling.

Operational Complexity

Debugging distributed systems. Local debugging is straightforward. Distributed debugging requires proper tooling.

Deployment pipelines. Local deployment is “run the code.” Cloud deployment needs CI/CD.

Monitoring requirements. Cloud systems need comprehensive monitoring. Build it before you need it.

Incident response. Cloud incidents require different skills than local troubleshooting.

Hybrid Approaches

Sometimes full cloud migration isn’t optimal:

Cloud AI with Local Processing

Use cloud AI APIs from local applications. Get AI capabilities without full migration.

Process sensitive data locally. Send only necessary information to cloud.

Prototype locally, deploy to cloud. Development stays local; production goes cloud.

Edge-Cloud Hybrid

Process at the edge, coordinate in cloud. Reduce latency and bandwidth with edge processing.

Local caching of cloud AI results. Improve response times for repeated queries.

Fallback to local models. When cloud is unavailable, local models provide continuity.

For cost-effective approaches, see my guide on cost-effective AI strategies.

Post-Migration Optimization

Migration is just the beginning:

Performance Tuning

Profile in production. Cloud performance differs from local. Profile after migration.

Optimize for cloud patterns. Caching, batching, and async processing work differently in cloud.

Right-size resources. Monitor actual usage and adjust resource allocations.

Cost Optimization

Reserved capacity. After usage patterns stabilize, commit to reserved pricing.

Spot instances for batch work. Fault-tolerant workloads can use cheaper spot instances.

Storage tiering. Move cold data to cheaper storage tiers.

Operational Maturity

Automate everything. Deployment, scaling, recovery: automation reduces errors and toil.

Build runbooks. Document common operations and troubleshooting procedures.

Practice incident response. Run drills to ensure the team can handle production issues.

The Path Forward

Migrating from local to cloud AI is a significant transition, but it enables scale, reliability, and collaboration that local development can’t provide. Plan thoroughly, execute in phases, and monitor closely.

The goal isn’t just to run the same code somewhere else, it’s to build a foundation for growth. Well-executed migration positions you for scale. Rushed migration creates technical debt that haunts you for years.
