One sign is that competition is getting fiercer.
Cisco, for instance, upped the ante against rivals like Riverbed, Packeteer, Juniper, Expand, and Blue Coat (to name just a few), by announcing today the 1000th customer for its Wide Area Application Services (WAAS). (See Cisco Widens WAN Optimization.)
Cisco's statement is a jab at Riverbed, which announced its 2,000th customer in April 2007 -- 300 percent over the 500 customers the supplier announced in January 2006. (See Riverbed Gets 2000 Customers.)
Cisco's solution, offered as both an appliance and a card for Cisco's ISR routers, has shipped in its present form since September 2006. (See Cisco Intros Services and Cisco Backs Into Optimization.) But Cisco says it added 100 customers in April 2007 alone.
