Are there any real world SaaS offerings on z/OS? The only tangible cloud
solution I've seen is the CICS PaaS applications/bundles and they don't
appear to have much appeal.
As far as cloud (private) is concerned it seems z/VM and z/Linux are the
only in town. OpenStack has been ported to z and that's for provisioning
z/VM instances. z/Manager didn't last
that long in that space. It seems to me that z/VM and z/Linux are the
cloud solutions on the mainframe. I would be happy to be proved wrong.

I would say that there is no expectation for the Data Center or Mainframe to
slide into the sunset. The processes on the Mainframe are more robust than
the open systems. Yes, open systems will catch up, but they are now where
we were 15 years ago.
And there are many processes that just perform better on the mainframe.
From an article in 2010 on Saas and the mainframe
http://dancingdinosaur.wordpress.com/2010/05/10/saas-and-the-ibm-system-z/
IBM's mainframe SaaS strategy envisions the mainframe as the center of SaaS
offerings based on mainframe functionality delivered as sets of services.
The goal is to enable IT to provide selected mainframe capabilities as
online services and generate new revenue for the company. In effect, IT
becomes what IBM refers to as rainmakers, using mainframe assets delivered
as SaaS.
Are mainframe managers ready to think this way? Some certainly are. What
mainframe data or functionality will your organization's customers or new
customers be willing to pay for?
In truth, the System z is well positioned to capitalize on the as-a-service
phenomenon. The System z is multi-tenant to the max, which is critical to
play the as-a-service game. Not only can it deliver SaaS data and
functionality but also PaaS (Platform-as-a-Service) and IaaS
(Infrastructure-as-a-Service). And it doesn't take much to do this if you
already have a z in place. Linux on z, WebSphere on z, and z/VM get you
started.
And from Share in March 2009
Software-as-a-Service (SaaS) is garnering a lot of attention these days, and
for good reason - increased operational efficiency, reduced operating
expenses, and extensive market reach is always a good thing. SaaS is most
often associated with commodity servers and open source software
environments, but this session will show how the mainframe is actually the
best platform for your SaaS solutions. The mainframes' 40+ year heritage is
built on the motto LESS IS MORE and it shows. The mainframe is Green. A new
z10 EC can consume 1/24th the energy and 1/5th the floor space of equivalent
x86 Blade environments. Mainframes, as consolidation systems, are uniquely
designed to virtualize and share everything - hardware, network, I/O, you
name it- it's shared, consuming the equivalent of 100s or even 1000s of
servers' workload. By default multi-tenancy, a core SaaS requirement, is
baked into the DNA of the platform, which is valuable for the many customers
who are rearchitecting existing applications to provide as a service.

Subject: Mainframe On Cloud
Hello All,
I am really new to the mainframe on Cloud concept. Just going through some
white papers on mainframe on cloud. I was just curious to know about the
future of current Mainframe sites, Like is it expected to see Mainframe DC
getting shutdown slowly ?
Any thoughts are much appreciated. If my query does not makes any
sense,please do feel free to comment, so that I can put in more precise way.
