Finally, in these last two sections, let's shift gears and implement a cloud service solution that we almost certainly couldn't build ourselves: a payment gateway. To do this, we will use the popular payment processor Stripe to configure a simple payment route. For our blog application, we might use such a feature to allow user donations or potentially offer premium features to paid users. The most important part of our implementation is keeping our user's payment information secure and safe from exposure to outside parties.
