TECH CORNER

Get in the CLOUD
z/OS solutions can connect to the cloud through REST interfaces

A

s industries take advantage of new accelerated capabilities in the
cloud, what does it mean for existing applications running on IBM
z Systems* servers? It's important to figure out what cloud is and show
how z/OS* plays an important role in its evolution.
Matt Hogstrom
is chief architect
and Distinguished
Engineer, z Systems
management and
IT optimization
software, IBM.
Kyle Charlet
is a Distinguished
Engineer and
z Systems architect
responsible for the
API economy for
z Systems at IBM.

You could ask three people
to define cloud and get at least
three definitions. Some people
use cloud as a noun and refer
to it as a destination. These
destinations often include providers such as Amazon, Azure,
IBM Bluemix* and Google. Each
of these vendors hosts resources
(e.g., compute, storage and networking) as well as services (e.g.,
load balancing, build and hosted
runtimes) and infrastructure
elements (e.g., VMs and storage)
to name just a few.
All of these resources share a
common attribute: they're easily
requested, managed and retired
using simple representational
state transfer (REST) APIs. Is this
the cloud? Not totally.
These services are used
together to form applications that
deliver client value to end users.
The applications (e.g., Google
Maps, Netflix, Salesforce, etc.)
represent software-as-a-service
offerings. They're easily consumed using REST APIs-generally with a sophisticated UI that
runs in a browser or a mobile

application. Is this the cloud?
Not really.
These examples show that
new applications can be innovated and delivered faster than
ever through the use of APIs
that cover the management and
consumption of resources via
REST APIs. Based on this, we
can define cloud as accelerated
consumption of IT resources by
developers to create and deliver
their new services via APIs. It's
not a destination but rather a
marked difference in the creation
and delivery of new applications.
Using this definition, how
does z/OS stack up in terms of
accelerated consumption of
resources and delivery of applications to customers? Today, it
provides means to manage and
consume resources through
the z/OS Management Facility
(z/OSMF) and enable access to
existing applications via z/OS
Connect. We'll examine both of
these capabilities and the value
provided to consumers who
develop new services and users
who consume them.

A Single Solution
During the 50-year history of
z/OS, organizations have invested
heavily in the creation of applications and services that drive their
core business. Because of their
longevity, these applications and
services tend to be efficient at
what they do while being stable.
z/OS Connect Enterprise Edition
(zCEE) offers a single solution
for access to z/OS applications
and resources. Historically, each
subsystem created its own solution
to solve a market need. This results
in different user experiences and
behaviors across the set of solutions that offer a given capability.
With zCEE, the subsystems come
together to offer a similar user
experience and behavior across all
supported subsystems. Additionally, the zCEE solution is open by
design and leveraging standard
means (namely the Open API Initiative specification) by which APIs
and their operations are discovered and managed.
Enabling applications to be
accessible as REST services results
in three benefits:
