 External resources on cloud computing for science
 =================================================
 
-The majority of cloud computing textbooks and AWS documentations are written 
-for web developers and system architects, NOT for domain scientists 
-who just want to do scientific computing and data analysis.
-As a researcher with limited IT background, it is crucial the pick up the 
-correct tutorial when learning cloud computing. Here are my recommendations:

-cloud-computing-for-research/cloud-computing-basics/>`_
-and 
-`technical documentation <https://cloudmaven.github.io/documentation/>`_

-[2] **Cloud Computing for Science and Engineering** (Foster and Gannon 2017)
-is the first textbook I am aware of that provides hands-on tutorials for domain scientists.

-gives a nice overview of various cloud computing applications in our field.
-It doesn't tell you how to actually use the cloud, though.
