### Key Considerations for Service Selection

1. **Compute Services**
   * VM pricing models and instance types
   * Container orchestration features
   * Serverless execution limits and pricing
2. **Storage Solutions**
   * Data residency requirements
   * Performance tiers
   * Replication options
3. **Database Options**
   * Scaling capabilities
   * Backup and DR features
   * Migration tools
4. **AI/ML Services**
   * Model training capabilities
   * Pre-trained models availability
   * Integration with existing tools
5. **Security & Compliance**
   * Certification standards
   * Identity management features
   * Encryption options
6. **Cost Management**
   * Pay-as-you-go vs reserved instances
   * Data transfer costs
   * Resource management tools
