I'm considering the CCSP as well. However, I've worked as a security pro for over 15 years (CISSP in 2004), have a ISACA CRISC, and also ITIL. So, I'm wondering, "do I really need to do more"?
Depends on your career aspirations. I think the cloud certification is relevant as that is the direction IT seems to be headed for the future. If you are at the top of the ladder where you work or you do not wish to go any higher then you probably don't need anymore certs, just stay relevant on new technologies. If you think you may need to change jobs in the future, getting more certifications can help round out your experience. If cloud is not for you then you may want to try project management or a management certification.
