OpenStack is an open-source software platform for cloud
computing that forms an Infrastructure as a Service (IaaS) stack,
with virtual servers and other resources being made available to
cloud users. It can be used with open-source software to create private
and public clouds; control large pools of compute, storage
and networking resources via a web-based dashboard or the
OpenStack API; and manage complex heterogeneous environments.
"If you were running Linux on the platform, you could leverage
OpenStack and we'd effectively gear up for the Linux guests as a
service. What you run in that Linux guest is up to you.
We'd handle the z/VM* layer, the Linux OS and hand it over as
a service at that level. This could also apply to enterprise
applications, analytics and web and mobile applications.
It's a very flexible environment," Dickens notes.

Leverage the Community
The LinuxONE Community Cloud provides easy and open access
VMs on Z to developers, academia, business partners and clients,
many of whom have expressed a desire to work on the mainframe
without having to purchase one. All that's needed to access
the cloud is an internet ID and cellphone. Within seconds, the
requestor will receive credentials to log on and deploy a VM for
120 days. Users are free to install many of the readily available
open-source software packages that fit their needs and interests.
"In recent months, we've accelerated the developer reach-out
programs, and in conjunction with the IBM Z announcement,
we announced the Unchain The Frame hackathon, where
thousands of users worldwide will be using the LinuxONE
Community Cloud to come up with new applications using
hyperledger and/or Docker developer journeys in the cloud,"
says Karl Duvalsaint, project executive, LinuxONE Cloud.
"As we move forward, we'll be deploying additional developer
journeys on the cloud as a means to let developers write new
applications efficiently and in an agile fashion to accelerate
growth on the platform."
IBM microservices involves the
cloud deployment of independent
mainframe services. If, for example,
a user doesn't have a mainframe but
wants to deploy Db2 for z/OS, she
can request that IBM set up an LPAR
on a cloud-based mainframe to
host it. This relieves costs and skills
concerns related to the purchase and
maintenance of a mainframe.
"If you don't want the rest of
the z/OS environment and all you
want is Db2, we could provide
that for clients," Dickens says.
"Typically, what we'd do is move
a client's entire environment onto
a cloud-based mainframe LPAR,
but in this case, it'd be a client that
doesn't have any an existing z/OS
environment and only wants to
interact with Db2 as a service.
"The same would also apply to
IMS* or CICS*. If you have only
a single mainframe application,
you may want a database and
a combination CICS and IMS
as a service-without any other
mainframe elements. This is a
very cost-effective way to take
advantage of advanced mainframe
