About

CloudMaterials.com is my blog to share notes and learning materials on Cloud and Data Analytics. My current focus is on Amazon Web Services.

I like to write. I try to document what I learn and share with others. I believe that knowledge is useless unless you share it; the more you share, the more you learn.
