Migrate from AWS to osModa: EC2/ECS/Lambda to Dedicated Servers
AWS is the most comprehensive cloud platform in the world, but that comprehensiveness comes with complexity. Running an AI agent on EC2 means managing instances, security groups, IAM roles, VPCs, and a billing dashboard that requires a finance degree to read. ECS adds container orchestration overhead. Lambda imposes cold starts and execution time limits. If your workload is a persistent AI agent -- not a globally distributed web application -- osModa replaces all of that with a dedicated NixOS server starting at $14.99/mo -- full root SSH, flat pricing, and built-in self-healing infrastructure.
TL;DR
- • AWS charges per-hour, per-request, per-GB, and per-service -- costs compound fast
- • osModa gives you a dedicated NixOS server with flat-rate pricing and zero billing surprises
- • Migration: export your config, spawn osModa server, SSH in, deploy your code
- • IAM roles and security groups are replaced by SSH keys and the Tier 0/1/2 trust model
- • AWS is better for massive scale and global distribution; osModa is better for always-on agents
Step-by-Step Migration from AWS
Migrating from AWS to osModa is straightforward for single-server AI agent workloads. The process typically takes 1-2 hours depending on how many AWS services you need to replace. Since osModa gives you a full Linux server with root access, the core concept is simple: export your AWS configuration, provision an osModa server, and deploy your application.
Step 1: Audit Your AWS Usage
Start by understanding exactly what you run on AWS. For EC2, note your instance type, AMI, security group rules, IAM role permissions, and user data scripts. For ECS, export your task definitions with aws ecs describe-task-definition --task-definition your-task. For Lambda, download your function code and note triggers, memory, and timeout settings. Document every environment variable. Run aws ce get-cost-and-usage to understand your actual monthly spend -- most teams are surprised by how many services contribute to the total.
Step 2: Spawn an osModa Server
Go to the osModa dashboard or use the API to spawn a server. Choose a plan based on your resource needs. If your EC2 instance is a t3.medium (2 vCPU, 4 GB RAM), the Solo plan ($14.99/mo, 2 CPU, 4 GB RAM, 40 GB storage) is the closest match. For larger instances, Pro ($34.99/mo, 4 CPU, 8 GB) or Team ($62.99/mo, 8 CPU, 16 GB) provide more headroom. Select a region: Frankfurt, Helsinki, Virginia, or Oregon. The server provisions in 5-10 minutes.
Step 3: SSH In and Install Dependencies
SSH into your new server with ssh root@your-server-ip. Unlike EC2 where you manage AMIs and user data scripts, osModa runs NixOS with declarative system configuration. Install your language runtime and system dependencies as NixOS packages. For Python workloads, enable python3 and pip. For Node.js applications, enable nodejs. If you ran Docker containers on ECS, you can install Docker on NixOS or (better) run your application directly without the container layer -- you already have an isolated dedicated server.
Step 4: Migrate Your Application Code
Clone your repository onto the server with git, or use rsync to copy files. Set environment variables from your AWS export. If you used RDS, either install PostgreSQL directly on the server (no per-hour database fees) or continue connecting to RDS externally. If your code uses the AWS SDK for services like S3, SQS, or DynamoDB, it will continue working -- just configure your AWS credentials as environment variables on the osModa server. Run your application just as you would on any Linux server.
Step 5: Replace AWS Services with Local Alternatives
For each AWS service you use, decide whether to replace it or keep connecting externally. CloudWatch monitoring is replaced by osmoda-watch, the Rust watchdog daemon that monitors and auto-restarts your processes. CloudTrail audit logging is replaced by the built-in SHA-256 tamper-proof audit ledger. Security groups are replaced by osmoda-egress for outbound network control. RDS can be replaced by PostgreSQL installed directly on the server. ElastiCache can be replaced by Redis installed locally. Keep using S3 if you need distributed object storage -- there is no reason to replace everything.
Step 6: Verify and Cut Over
Test your application on the osModa server while your AWS resources continue running. Verify all endpoints, API connections, and database queries work correctly. Once confirmed, update DNS records, webhook URLs, or client configurations to point to the new server. After verifying production traffic flows correctly, terminate your EC2 instances, delete your ECS services, and remove Lambda functions. Check your AWS billing dashboard a few days later to confirm charges have stopped.

Key Differences: AWS vs osModa
Complexity vs Simplicity
AWS is designed for organizations that need to serve millions of users across dozens of regions with hundreds of integrated services. That power comes with real complexity: IAM policies, VPC configuration, security groups, NACLs, service quotas, and a billing model with thousands of line items. For a team running one to ten AI agents, most of this infrastructure is overhead you pay for in both money and engineering time. osModa removes that overhead entirely. You get a server, you SSH in, you run your agent.
Per-Hour Billing vs Flat-Rate Pricing
AWS charges for compute by the hour (EC2), by the request (Lambda at $0.20 per million invocations plus $0.0000166667 per GB-second), by the GB transferred ($0.09/GB egress), and per-service (RDS, ElastiCache, ALB, CloudWatch, CloudTrail, etc.). A production EC2 setup with a load balancer, managed database, and monitoring easily reaches $80-150/mo for resources comparable to osModa's Solo plan at $14.99/mo. The difference is not just cost -- it is predictability. osModa's price does not change based on traffic, data transfer, or API calls.
When AWS Is the Better Choice
AWS is genuinely better for workloads that need horizontal auto-scaling across regions, serverless event-driven architectures, managed services like DynamoDB or Kinesis at scale, or compliance certifications like FedRAMP and HIPAA. If your application serves unpredictable traffic spikes across multiple continents, AWS's infrastructure is purpose-built for that. osModa is not a replacement for AWS at enterprise scale -- it is a replacement for the common case of running persistent AI agents where AWS's complexity provides no benefit.
When osModa Is the Better Choice
osModa is designed for always-on AI agents that need dedicated resources, predictable pricing, and operational simplicity. If your workload is a persistent process (not a request-response web app), if you are tired of debugging IAM permissions, if your AWS bill is 80% overhead services (ALB, NAT Gateway, CloudWatch) around 20% actual compute -- osModa eliminates all of that. You get a dedicated server with 9 Rust daemons handling monitoring, networking, security, and recovery automatically.
What You Gain
Moving from AWS to osModa for agent workloads gives you flat-rate pricing with zero billing surprises, full root SSH access without IAM role gymnastics, self-healing via osmoda-watch (Rust watchdog daemon), SHA-256 tamper-proof audit logging without CloudTrail fees, NixOS atomic rollbacks via SafeSwitch, egress control via osmoda-egress, and multi-channel support (Telegram, WhatsApp, Discord, Slack) for agent communication. You also gain access to AI models (Claude Opus/Sonnet/Haiku, GPT-4o, o3-mini) through the platform.
What Requires Adjustment
osModa does not provide horizontal auto-scaling, global CDN, managed databases with multi-AZ failover, or 200+ integrated services. If you rely on AWS Lambda for event-driven architectures, you will need to restructure around long-running processes. If you use DynamoDB, Kinesis, or other AWS-specific services, you will need alternatives or must continue accessing them via API. Teams accustomed to CloudFormation or Terraform will use NixOS declarative configuration instead. The trade-off is less automation for simpler, more predictable operations.

Frequently Asked Questions
How do I export my EC2 instance configuration?
Document your instance type, security group rules, IAM roles, and user data scripts. Export environment variables from your application. If you use RDS, create a snapshot or pg_dump export of your database. For ECS, note your task definitions including CPU, memory, environment variables, and container commands. For Lambda, export your function code and note triggers, memory settings, and timeout values.
What replaces AWS services like RDS, ElastiCache, and S3?
For RDS, install PostgreSQL or MySQL directly on your osModa server via NixOS packages -- no per-hour database fees. For ElastiCache, install Redis directly. For S3, you can use MinIO for S3-compatible object storage on the server, or continue using S3 directly via the AWS SDK if you need globally distributed storage. osModa does not lock you into a service ecosystem -- you connect to any external service via API.
What about IAM roles and security groups?
osModa uses a simpler security model. Network access is controlled by osmoda-egress, which manages outbound connections at the daemon level. The Tier 0/1/2 trust model replaces IAM's role-based access. SSH access uses standard key-based authentication with full root access. There is no 40-page IAM policy to debug. For applications that still need to call AWS APIs, you can use IAM credentials as regular environment variables.
Can I still use AWS services alongside osModa?
Yes. osModa servers have full outbound internet access (controlled by osmoda-egress). You can call AWS APIs like S3, SQS, DynamoDB, or Bedrock from your osModa server just as you would from any Linux machine. Many teams migrate compute to osModa while keeping specific AWS services they depend on. This is a practical approach -- move your EC2/ECS workloads to flat-rate pricing while keeping the AWS services that make sense.
How does pricing compare between AWS and osModa?
An EC2 t3.medium (2 vCPU, 4 GB RAM) costs roughly $30/mo on-demand, plus EBS storage ($8/mo for 80 GB), plus data transfer ($0.09/GB out), plus an ALB ($16/mo + per-request fees), plus RDS ($25-50/mo), plus CloudWatch ($3-10/mo). A comparable production setup easily exceeds $80-120/mo. osModa's Solo plan gives you 2 CPU, 4 GB RAM, and 40 GB storage for $14.99/mo flat -- no data transfer fees, no per-service billing, no surprises on your bill.
How does auto-scaling work on osModa vs AWS?
AWS excels at horizontal auto-scaling -- EC2 Auto Scaling Groups, ECS service scaling, and Lambda's automatic scaling to thousands of concurrent invocations. osModa does not auto-scale horizontally. Each server is a dedicated machine. If you need more capacity, you spawn additional servers and configure routing. osModa is designed for always-on AI agent workloads with predictable resource needs, not for bursty web traffic that needs to scale from zero to thousands of instances.
