Hello,
Please be aware that free trial accounts for the Cloud Platform have limited quota during their trial period. If that is your case, you'll need to upgrade to a paid account,
because the trial accounts have a hard limit on quota [1].
Otherwise, please engage our Sales team [2] who handle capacity requests in the region of your choice.
