of running APIs close to the
data source itself, Soto says.
Node.js runs 2x better on
Linux on z Systems than on
competitive platforms. Further,
when Node.js is co-located with
data and transactions native on
z Systems, the system sees a 60
percent reduction in response
times and 2.5x improvement
in throughput.
"These statistics point to the
power of running Node.js and
implementing performancecritical APIs right on Linux on
z Systems," Soto notes.

API Connectivity
To bring IBM and Node.js
synergies together, in March,
IBM released IBM API Connect*,
which integrates IBM's API
management and gateway
offerings along with API creation
and runtime capabilities using
StrongLoop's Node.js and IBM's
Java* technologies.
"This enables companies
of all sizes to create, run,
manage and secure APIs that
access information on existing
IT systems, including the
mainframe or anywhere in the
back office as well as services
and data in the cloud," Soto says.
"It also enables high developer
productivity using Node.js to
create new APIs."
With its built-in, integrated
support for both Java and
JavaScript* (the programming
language used by Node.js) for
API development and execution,
IBM API Connect is the only
API solution on the market that
covers the two most popular
programming languages in a
single offering, Soto notes.
APIs allow applications to

interact with each other and serve
data and services to mobile, rich
Internet applications and IoT
devices. APIs allow component
services to be moved elsewhere
in the cloud without breaking the
overall solution, Soto says. As
long as the solution uses APIs to
integrate the component services,
their interfaces remain consistent
even as their implementation or
execution locations change.
APIs also enable businesses
to tap new revenue streams.
Enterprises can leverage their
existing IT investments and
the services those investments
create to drive revenue growth
and expand into new business
areas. For example, a bank can
offer APIs to Web and mobile
businesses, allowing them to use
its banking APIs for transactions.
"You are getting the advantage of
driving new usage and creating
new business opportunities from
services you've built over the
years," Soto says.
Companies offering APIs for
external access can make them
freely accessible to drive as much
penetration and adoption as
possible, or control access to the
APIs to bill for their usage or for
security reasons.
"A powerful API management platform, such as
IBM API Connect, not only
allows you to create and run
APIs but also manage those
APIs by defining access policies
from the start," Soto notes.
"Then, with solutions from
IBM, such as IBM DataPower*
Gateway, you can seamlessly
enforce those data policies
directly in the gateway
without requiring
additional programming."

The Rise of
Microservices

D
Ubuntu is a
cloud-enabled
distributor with
a footprint that
claims

70 percent
of OpenStack-enabled
systems,

70 percent
of public cloud
images and

70 percent
of Docker Hub
images

Node.js runs

2x
better on Linux
on z Systems
than competitive
platforms.
Further, when
Node.js is colocated with data
and transactions
that are native on
z Systems, the
system sees a

60 percent
reduction in
response times
and a

2.5x
improvement

Individual APIs can also be used to
create a new API tier to handle the
evolving demands from mobile,
rich Web and IoT. Many enterprises
are creating such an API tier on the
edge of their enterprise network.
Rather than directly accessing
data and services spread among
systems of record and in the cloud,
an API tier enables enterprises to
combine and optimize service and
data access, increasing overall
performance, controlling access to
back-end systems and improving
overall reliability.
The API tier is increasingly
implemented as a collection
of microservices-each with
a modular, highly specific
function-exposed as managed
APIs to systems of engagement.
From there, developers can
quickly aggregate and optimize
APIs to deliver the critical
services powering innovative
applications accessed by
customers,employees or partners.
"APIs enable companies to get
into new business areas, protect
their existing ones, and deliver
a better experience to their
customers, their partners and
their employees," Soto says.

Providing Services
Linux on z Systems supports,
enables and advances hybrid
cloud, the API economy and
microservices as well as the
business benefits these services
provide. This allows your
business to stay competitive
and thrive in this ever-changing
environment.
