Serverless-on-Steroids: Why service.do is the Ultimate Platform for Business Logic

In modern software development, we've mastered building sleek UIs and robust backends. Yet, a critical component often remains a tangled mess: business logic. Complex operational workflows—like onboarding a new customer, processing a multi-step financial transaction, or generating a custom report—are frequently scattered across different systems, trapped in manual processes, or hardcoded into monolithic applications. This creates technical debt, slows down innovation, and makes scaling a nightmare.

What if you could treat your business operations with the same rigor and elegance as your core software?

That's the mission of service.do. We believe your business logic shouldn't be a liability; it should be your most powerful asset. With our Agentic Workflow Platform, you can define any business capability as a robust, versioned service and deploy it as a simple API. This is the future of operations: Services-as-Software.

Define. Deploy. Deliver. The "Business-as-Code" Philosophy

At its core, service.do is built on a simple yet powerful idea: Business-as-Code. It’s the practice of encapsulating a specific business function into a self-contained, deployable software component.

Think about a common workflow: Customer Onboarding. This process might involve:

1. Creating a user account.
2. Setting up a billing plan.
3. Sending a welcome email.
4. Adding the user to a CRM.
5. Notifying the sales team via Slack.

Traditionally, orchestrating this would involve a complex dance of API calls, message queues, and custom glue code. It's brittle and hard to change.

With service.do, you define this entire workflow in a single, clear file.

From Logic to Live API in Minutes

You don't need to learn a proprietary language or a complex visual builder. If you know TypeScript, you're ready to build on service.do. Our SDK provides a clean, declarative way to define your service's inputs, outputs, and logic.

Here’s what that customer onboarding service looks like in code:

import { Service, type Context } from '@do/sdk';

// Define the input and output schemas for your service
interface OnboardingInput {
  name: string;
  email: string;
  plan: 'free' | 'pro' | 'enterprise';
}

interface OnboardingOutput {
  customerId: string;
  welcomeEmailSent: boolean;
  status: 'complete' | 'failed';
}

// Create a new Service instance with your business logic
export default new Service<OnboardingInput, OnboardingOutput>({
  name: 'customer-onboarding',
  description: 'Onboards a new customer, creating an account and sending a welcome email.',

  async run(input: OnboardingInput, context: Context): Promise<OnboardingOutput> {
    console.log(`Starting onboarding for ${input.email} on plan ${input.plan}`);

    // Business logic goes here.
    // e.g., call user.create, email.send, billing.setup agents
    
    const customerId = `cust_${context.invocationId}`;

    return {
      customerId,
      welcomeEmailSent: true,
      status: 'complete',
    };
  },
});

Let's break this down:

• Clear Contracts: The OnboardingInput and OnboardingOutput interfaces explicitly define the data your service expects and what it will return. This creates a strong, self-documenting contract for any application that uses it.
• Focused Logic: The run method is where your business logic lives. It’s a standard async function, giving you the full power of modern JavaScript to orchestrate tasks.
• Deployment, Simplified: Once you write this code, you're done. The service.do platform handles the rest. We take your code and automatically deploy it as a secure, scalable, and versioned API endpoint. No Dockerfiles, no Kubernetes configs, no server management.

Is This Just a Microservice? No, It's an Agentic Workflow.

You might be thinking, "This sounds like a microservice." While there are similarities, a .do Service is purpose-built for a different, higher-level task: orchestration.

This is where the concept of an Agentic Workflow comes in. A .do Service acts as a master agent, delegating tasks to other specialized agents or services. In the code example, the comments // e.g., call user.create, email.send, billing.setup hint at this. Your onboarding service doesn't need to know how to create a user; it just needs to invoke the user.create agent and trust it to do its job.

This approach offers significant advantages over traditional microservice architectures:

• Decoupling: Services are highly decoupled. You can update your email-sending logic without ever touching the onboarding service.
• Reusability: A single billing.setup service can be used by your onboarding workflow, a plan upgrade process, and an internal admin tool.
• Clarity: The logic for the entire business process is defined in one place, making it easy to understand, debug, and modify.

The Ultimate Serverless Experience

The title calls service.do "Serverless-on-Steroids," and for good reason. We provide a fully serverless platform, meaning you never have to think about infrastructure.

• Zero Server Management: Write your code and push. We handle the deployment, execution environment, and networking.
• Infinite Scalability: Whether your service is called ten times a day or ten thousand times a minute, the platform scales automatically to meet demand. You pay only for what you use.
• Built-in Security: Every service is deployed as a secure API endpoint, with authentication and authorization handled by the platform.

You get to focus entirely on delivering business value, not on managing servers.

What Will You Build with service.do?

The possibilities are limited only by the processes you can imagine. Any workflow that you can describe as a series of steps is a perfect candidate for a .do service. We've seen our customers build:

• Customer Onboarding Workflows: As shown above, a classic and powerful use case.
• Data Enrichment Pipelines: A service that takes a company domain, finds contact information, and enriches a CRM record.
• Automated Financial Reporting: A service that runs monthly, pulls data from multiple sources, and generates a P&L statement.
• Lead Qualification Systems: A service that scores new leads based on company size, industry, and user behavior.
• Content Generation Services: An AI-powered workflow that takes a topic, generates an article, finds an image, and posts it to your blog.

If your business runs on processes, service.do can turn them into scalable, on-demand software.
