If you need to split a string based on uppercase values, for example “ComputeAsAService” in order to provide a readable string “Compute As A Service” you can do so simply by using regular expressions, in particular you can use the lookahead operator “?=”.

str = "ComputeAsAService"
parts = str.split(/(?=[A-Z])/)
>> ["Compute", "As", "A", "Service"]

Once you have all parts of the string, you can join them with a space, or simply deal with the array as you see fit.

str     = "ComputeAsAService"
parts   = str.split(/(?=[A-Z])/)
new_str = parts.join(' ')
