Not much. In fact, all you need to know is how to get to the Oracle Cloud Marketplace website.
Here’s the link:
You can browse and search the marketplace products in much the same way as you shop for products on other online stores.
If you find an app or a service you want, then you must sign in with your Oracle account.
Be sure to add Oracle Cloud Marketplace to your list of favorite websites or bookmark the home page so you can easily return to the marketplace.
