Zing let free to open source Java developers

For the radical Zing JVM to gain traction against the more seasoned options, an open source version was always on the cards. Now it’s here

Azul Systems, makers
of the souped-up Zing JVM have pledged allegiance to Java’s
development moving forward, releasing a free version to open source

Arguably the most advanced JVM on the market  and based on
Oracle’s Hotspot JVM, Zing became
generally available in October 2010, garnering critical acclaim for
its fresh new take on Java performance and scalability, in part due
to offering pauseless garbage collection. Coming up to two years on
from that date, now seems the ideal time to reach out to the
community and show them the benefits of switching to the
armour-plated Zing.

Over that time, the concept behind Zing has been pushed on further,
aiming to become the number one JVM choice for Java developers.
Alongside support for Ubuntu and becoming the first fully native
JVM for Linux, April’s 5.2 released added in new management tools
for controlling multiple Zing JVM instances. The latter is hugely
important for making an enterprise charge, with business always
looking for new ways to control numerous JVM instances

The Zing JVM boasts key benefits over its rivals through its
elastic scalable option, and now open source Java applications can
take advantage of Zing’s offer of improved responsiveness and
reduced latency. Other areas where Zing excels is through its
support for large, in-memory data processing and how the heap
reacts to real-time demand elastically. It is designed to thrive
under hardship and make light work through normal runtimes. In
turn, this makes Zing an ideal choice for obtaining analytics of
your JVM performance.

This new initiative will allow open source developers the
opportunity to put Zing through its paces, through their
applications running on Red Hat Enterprise Linux, SUSE, CentOS or
Ubuntu Linux.

Already a member of the Java Community Process’s Executive
Committee (who provide guidance and cast votes for Java
innovation), this open source offer was a given if Azul Systems
were to achieve leverage in a crowded space. Thankfully, they’ve
already made enough of a splash with their unique JVM solution, so
seem ideally placed to further pick-up rate.

“Our goal is to make Zing the de facto choice for Open Source
developers to achieve the most consistent Java performance and
scalability,” said Scott Sellers, Azul Systems president and CEO.
“Azul’s development teams have made extensive use of Open Source
technologies over the years, and our new Open Source development
initiative is another example of our commitment to the Java
community and embracing Open Source software. We have put the
lowest–latency and most scalable JVM freely into the hands of Open
Source developers, removing the bottlenecks commonly associated
with the Java runtime and enabling application innovation in a
plethora of new markets such as in-memory computing and Big Data

They’ve certainly been noticed by some of the best experts in the
industry, with Zing becoming the obvious choice for advanced

“As developers have become increasingly important in adoption and
procurement patterns over the past decade, availability has become
a key factor in overall technology usage,” said Stephen O’Grady,
Principal Analyst at RedMonk. “With this announcement, Azul is
trying to make it easy for open source developers to leverage and
incorporate the Zing JVM.”

“Programming and architectural approaches that leverage
immutability to enhance concurrency and scale will be well-matched
by a runtime that is able to support high continual allocation
rates without disruptions or pauses. By making the Zing JVM
available to Open Source developers, Azul is making a fantastic
contribution to the community,” said Rich Hickey, author of Clojure
and designer of the Datomic database system.

We salute Azul Systems’s Zing for bringing a new perspective to
what a JVM can do, and that they are seeking to facilitate change
through the JCP. If you’re looking to handle large heaps and heavy
loads, the free version of Zing might just be for you.

Developers who are interested in using the Zing JVM

Azul Systems CTO and co-founder Gil Tene next week – we’ll be
talking garbage collection, recent Java developments and where Azul
Systems are heading in the future.
