Everyone seems to jumping on the 'new' (not new at all) idea that a mainframe can be used in the cloud. SD Times article in October 2011 states: "While datacenter utilization can be tricky to optimize above 30% even with virtualization and workload tools, mainframes tend to run at over 80% of capacity."

In my work with mainframe customers from Cloud 1.0 to Cloud 2.0, I see the high cost, rigid applications, and legacy 'lock in' that hard coding business rules in application logic causes. See this article here:

In the early 1960s when companies started migrating to the Cloud 1.0 (mainframe-based cloud), existing computerized systems to migrate from did not exist. The manual systems, that sometimes the computerized application replaced, were rudimentary and easily replaced by a computer-based system. This made moving to Cloud 1.0 much easier than Cloud 2.0 migrations as you where implementing a new system clear of any legacy ‘baggage’. Today, companies are shackled with hundreds of business applications based upon mainframes, mid-range, and client/server systems deployed using mostly custom developed applications or Commercial Off-The-Self (COTS) products. Migrating existing IT systems to the Cloud 2.0 involves migrating everything from the data to the application, application deployment solutions or procedures, management and monitoring software, integration, data warehouse, business intelligence, replications solutions and backup and recovery, and perhaps even hardware infrastructure.

The mainframe really was Cloud 1.0. Very good article here: http://www.infoworld.com/d/data-center/new-job-mainframes-hosting-private-clouds-329. Oracle Exadata and Exalogic are Cloud 2.0. Similar to to Cloud 1.0 but much improved: based upon open standards network, storage, relational databases, Java EE and processors.
