I think the next exam I'm going to target is developer. I hear there is quite a bit of overlap between SA and Dev material. Hopefully knock that out in a couple weeks and might as well then finish the trifecta with SysOps. From there, I'll likely run through a good bit of the DevOps material as that is a definite weak area for me. I work with traditional datacenter technologies today (private cloud on vmware) but want to make the jump to public cloud, possibly with AWS directly. Seem to be the proper route.
