Big release for Scala fans

Typesafe Stack 2.0 is here, welcoming Play Framework in the fold

Typesafe announce the second major version of their commercial offering – marrying together Scala, Akka, Play and a brand new console.

Today, Typesafe announced the release of the latest version
of its open source software stack Typesafe
Stack 2.0
, proclaiming itself as a comprehensive platform for
building highly scalable applications in Java and Scala. The
significant addition to the open source version and commercial
offering this time round is the inclusion of the innovative Play
web framework for the first time, which Typesafe announced back in
The distribution brings together the three big-hitters from the
company – the increasingly popular programming language Scala
2.9.1-1, middleware framework Akka 2.0 and the
aforementioned Play Framework. Alongside that, there’s commercial
support, maintenance and deployment tools on offer through Typesafe
Subscription. This includes exclusive subscriber access to the new
Typesafe Console, a monitoring and management tool for the Typesafe
Stack. The console complements the Typesafe Stack with an
enterprise-grade dashboard for monitoring and administering

Typesafe CEO Donald Fischer told us what sets Typesafe Stack 2.0
apart from other distributions.

He said: “The Typesafe Stack is all about building applications
in Java and Scala that can scale to the largest workloads in cloud
computing and virtualized datacenter environments. Our emphasis on
scalability permeates every layer of the stack from the Scala
language to the Play framework. Aside from scalability, the
Typesafe Stack also emphasizes developer productivity at every
layer — with fewer lines of code, less boilerplate, and better
tooling all around.”

Martin Odersky, Chief Architect and Chairman at Typesafe
spoke of how the stack is reacting to developer wants and needs as
the landscape changes.

He said: “Requirements for developing applications that
can handle today’s multicore and parallel computing workloads are
changing rapidly.” He added: “We’ve seen increased demand from
enterprise customers for a comprehensive developer stack to help
them solve these challenges.”

The inclusion of the Play Framework certainly
adds calibre to the offering, and recognises a growing demand from
developers for a Java/Scala hybrid when it comes to web

Creator Guillaume Bort spoke of the logical decision to
include it in this latest version, saying that 
its inception, the Play Framework was created to bring a fresh web
development experience inspired by modern web frameworks like Ruby
on Rails to the Java web developer community.” 

Typesafe Stack 2.0 also includes key new enhancements to
Akka middleware. Akka 2.0 features improved performance scalability
with up to 2.7 million actors per GB of memory. Actors
more transparent too, so actors may reside
locally or on a remote node, without any change in application code
or semantics.

Scala seems to be over the stage where everyone left,
right and centre was savaging its flaws, rather than praising its
strengths. Fischer has indeed noticed the upward trend, at least
commercially for using Scala and that it has certainly permeated
the Java landscape and into the mainstream.

He said: “You can see it in the metrics — job
listings mentioning Scala, testimonials from large scale users like
Guardian and Klout. And you can feel it in
the air at developer gatherings like Devoxx and JFokus.”

Fischer seems to think that Scala and Java can be bedfellows for
the time being. He said: “We’ve always considered it essential
to cater to both Java and Scala developers. For example, Akka has
always had native APIs for both Java and Scala, and the Play
framework continues that tradition…It’s hard to predict the
distant future, but in the near term, we see Java and Scala
co-existing nicely in the commercial software environment.”

Typesafe Stack 2.0 is a big step for the company and the Scala
language in general. With some big companies putting their faith in
the complex language, the future is indeed looking bright for
