## Key Features

<CardGroup cols={2}>
  <Card title="Failure Resilience" icon="shield">
    If your platform experiences a temporary outage, your workflow can pick up right where it left off, ensuring stability even in unstable environments.
  </Card>

  <Card title="Long-Running Executions" icon="clock">
    Run long-running REST endpoints, such as complex AI models or video processing tools, even on serverless platforms with strict time limits.
  </Card>

  <Card title="Events with Wait/Notify Mechanism" icon="bell" href="/workflow/features/wait-for-event">
    Create workflows that wait for external events before proceeding. Ideal for user confirmations and asynchronous notifications.
  </Card>

  <Card title="Scheduled Jobs" icon="calendar" href="/workflow/howto/schedule">
    Run jobs at regular intervals with support for cron expressions. Perfect for recurring tasks like reminders, reports, or newsletters.
  </Card>

  <Card title="Parallel Runs" icon="road" href="/workflow/features/parallel-steps">
    Start independent tasks in parallel and wait for them to finish simultaneously, reducing latency.
  </Card>

  <Card title="Long Delays" icon="hourglass" href="/workflow/basics/context/sleep">
    Need your code to “sleep” for days, weeks, or even months? Supports long delays beyond serverless time limits.
  </Card>

  <Card title="Delivery Guarantees" icon="rotate-right">

## How it works

Upstash Workflow builds on the principle of steps. Instead of defining a single, complex piece of business logic, workflows contain multiple individual steps.

Each of the steps are executed by a separate request to your application, by preserving the output of previous steps.

In case of an error, a failed step is retried individually without needing to re-run any previous steps. Instead of the entire business logic, *each step* can take up your serverless function execution duration, and many more benefits.
