Actually now a days Cloud Computing is a lucrative option after getting CCNA Certified because it is closely related to Networking, more than DevOps. Also, being certified in CCNA helped professionals gain valuable knowledge and recognition in Networking for those who needed entering the Cloud Computing domain, where their competencies in Networking would prove to be of great use.
You should consider going for DevOps if you have more of a programming background. DevOps is closely associated with software life cycle rather than networking and cloud.
Both the fields offer good career paths, choose wisely as per your interest in the domain and your career background and experience.
If you do not have any prior experience, think about taking DevOps Post Graduate Program before you begin the career path in this field.
Hope this is helpfull!!
