IBM (IBM) sells middleware software and technology services such as outsourcing and integration to large and medium sized businesses worldwide, and competes with firms like Oracle (ORCL) and Red Hat (RHT). IBM is also among the global leaders in business systems and competes with hardware vendors like Hewlett-Packard (HPQ) and Dell (DELL) in the server market as well as firms like EMC (EMC) and NetApp (NTAP) in the storage market.

The firm chooses to call this new emerging category "Smarter Commerce," keeping in line with its Smarter Planet initiative. We have earlier discussed IBM's focus on its Smarter Planet initiative and how the firm stands to benefit from it. (See IBM's Smarter Planet Initiatives Lay Groundwork for Growth.)
