AWS certifications are aligned to two broad streams – Solutions Architect and DevOps Engineer. The Solutions Architect stream is well defined; you should first bag the Solutions Architect – Associate certification followed by the Solutions Architect – Professional certification. But if you choose to certify yourself as an AWS DevOps Engineer, you have to either clear the Developer – Associate certification or the System Operations (SysOps) Administrator – Associate certifications.

While Solutions Architect is an independent stream in itself, a Developer and/or SysOps Associate certification can lead you to a DevOps Engineer certification.
