Logo is stylization of your brand name "CloudNine".
The creative point is that a part of letters D, E and a arc at the right side of the logo are used to represent a part of a cloud image.
Beside that, letter "O" in word "CLOUD" and a part of the second letter "N" in word "NINE" are joined together and creat a number 9 image by a very intelligent way.
