Did you miss the last months birthday? Yes, COBOL turned 50 last month. I could blather on about how there are 30 billion COBOL and CICS transactions a day, or how their are still well over 1 million COBOL programmers, or about how there may be as many as 5 trillion lines of COBOL code out there running there largest institutions. Instead, let's just say Happy Birthday, to this commercially oriented business object language and, like your grandpa, remember to give it some respect!
As a field architect, I have the opportunity to run into all kinds of customers and situations. This means I get to read all kinds of technology. Recently, I had the opportunity to take a closer look at one aspect of virtualization across our server platforms in IBM and found myself very encouraged in the direction we're going. You may recall last year at this time IBM announced, and later followed through on, the acquisition of the Transitive company.
About six months later, IBM announced PowerVM, which provided the capability to consolidate sets of applications across power systems (AI, IBM i, and Linux). This included the rapid deployment of workloads in partitions, and even the live transfer of running workloads. There's a lot of detail in features about the resource sharing, the implementation of micro-partitioning where you can have as many as 10 dynamic logical partitions per processor core and so on, but the exciting thing is to see the direction of virtualization and that concepts started on System z percolate down across other platforms. I recently heard about the impact at a conference where a video running out of a partition was moved across physical machines live on the conference floor -- who wouldn't like to have seen that?
Remembering how the i-series was moved to power systems, learning that Transitive helped move Apple systems across chipsets, and seeing examples everywhere of increased management and utilization of processor resources (such as the recent z/OS enhancement for zAAP eligible workload on zIIP engines), it just gets one itching to see the next result of that virtualization acquisition in Transitive!
