If you are looking for more practical resources related to architectures in the cloud, you should take a look at https://coderecipe.ai . It is a dev community that allows others to share recipes (architecture + pros/cons/limitation/cost analysis + deployment instruction + source code) that can be used directly in real life situations.

If you have one or a few specific domain of architectures in mind, for example “how to do user management in AWS”, you can search for a collection of similar architectures like this https://coderecipe.ai/search?q=%23usermanagement , this way you can compare different alternatives. Similarly, if you are interested in different ways to “Store time series of data”, there’s also a collection of that here https://coderecipe.ai/search?q=%23timeseriesdb. The site contains a lot of recipes that is based on serverless design, so this will give you everything serverless related https://coderecipe.ai/search?q=%23serverless .

I am the founder of this platform, currently we have mostly AWS related recipes but there will be more GCP and Azure stuff coming soon, let me know if you have any questions :)
