You have a good point, but he at least partially addressed this in the article when he said "First, I really like the use of the article “a” in reference to cloud as it speaks to all models of cloud: private, public, external, internal, and hybrid." A company that cannot or will not put their data on the internet and "The Cloud" could at least in principle build "A Cloud" within their own intranet and host there, still gaining the flexibility of focusing on applications rather than servers. Still, I think you have a good point with cloud computing makes some servers obsolete. Some data not only cannot leave the company intranet, but must be segregated strictly from other data within in the same company. This will require focusing on the server. Also, it can (in some cases) be harder and slower to write in such a flexible than to let it be tied to a single server. Doing that makes no sense if programmer time is a precious asset in that organization and you will have a need for massive scaling in the foreseeable future.
