I was first introduced to the concept of cloud back in the fourth grade. For most of us, the word cloud meant those little balls of cotton that exist in the sky. Little did I know that there would be a cloud in the virtual world as well! Come to think about it, there is even a little similarity in both these types of clouds. While the first one is used to save our thoughts and dreams (excuse me for being poetic!), the second one is being used to secure data.
