Great, show me a single product (besides AWS SWF and Azure durable Task Framework) that has the programming model of Temporal. For example, which product allows to write production code like this that survives any process failures:

  public void execute(String customerId) {
    activities.sendWelcomeEmail(customerId);
    try {
      boolean trialPeriod = true;
      while (true) {
        Workflow.sleep(Duration.ofDays(30));
        activities.chargeMonthlyFee(customerId);
        if (trialPeriod) {
          activities.sendEndOfTrialEmail(customerId);
          trialPeriod = false;
        } else {
          activities.sendMonthlyChargeEmail(customerId);
        }
      }
    } catch (CancellationException e) {
      activities.processSubscriptionCancellation(customerId);
      activities.sendSorryToSeeYouGoEmail(customerId);
    }
  }
