"Commercially reasonable" is a standard legal term used to define efforts short of "best efforts". It allows for the party also look out for its own commercial interest in a way that's consistent with industry practice. So, for example, if Amazon had to choose between fulfilling the SLA and keeping it's own retail site up, it could be held liable under a "best efforts" standard but not under a "commercially reasonable" standard.
It's kind of unfair to describe these as "weasel words" when it's unlikely that any decent lawyer would let them sign up to something that exposes them to more liability than this. Customers who are using any cloud service provider have to expect reasonable steps to maintain availability, not an absolute promise.
