Bitnami Launchpad for AWS (https://aws.bitnami.com/) gives you an intuitive Web-based dashboard to create and manage your AWS Cloud servers. This is a place where you can find all the Bitnami applications, start/stop/reset the server, ease of obtaining the password, etc. But, of course, in the background, the instance is launched in AWS so you can manage it using the AWS console or dashboard as usual.
The previous image is a screenshot from the Bitnami Launchpad for AWS, as you can see you have some links to access to the application website, admin website, the credentials, etc and also, you have another button redirecting you to the AWS console.
When Bitnami does a new release of an application, it is done automatically in our Launchpads for the different clouds, but the marketplaces are not controlling by us, so although we sent the new version to AWS, they publish it in their marketplace according to their calendar, we have not control about AWS publish workflow.
You can find more information and a "Get Started" guide about Bitnami Launchpad in this link.
