I need to find information about technologies (better if open source) available in the cloud: storage, database, containers, security, providers, etc.. Is there a place where I can get an overview of these technologies and know which products are available please?
I found this repository of CNCF on github and in particular this picture, that gives you the most updated snapshot of all available technologies.
I think it's what you need to have an overview of this wide cloud world.
