Frontend Configuration

interface ServiceTemplate {
  name: string;
  description: string;
  parameters: Parameter[];
  resources: CloudResource[];
}

interface CloudResource {
  provider: 'aws' | 'azure' | 'gcp';
  type: string;
  configuration: Record<string, unknown>;
}

const webAppTemplate: ServiceTemplate = {
  name: 'Web Application',
  description: 'Production-ready web application with monitoring',
  parameters: [
    { name: 'environment', type: 'string', allowed: ['dev', 'staging', 'prod'] },
    { name: 'instanceSize', type: 'string', default: 't3.micro' }
