The Language of Pragmatism
Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. Scala smoothly integrates features of object-oriented and functional languages, enabling developers to be more productive while retaining full interoperability with Java and taking advantage of modern multicore hardware. Scala makes it easy to avoid shared state, so that computation can be readily distributed across cores on a multicore server, and across servers in a datacenter. This makes Scala an especially good match for modern multicore CPUs and distributed cloud-computing workloads that require concurrency and parallelism.
Thanks to its type inference and other features, Scala is a succinct language, typically enabling developers to reduce the size of source code by at least a factor of 2 or 3 compared to Java. Scala is bundled with a rich set of developer tools, resulting in productivity comparable to languages like Ruby or Python, while retaining the performance advantages of Java.
Scala allows us to write better, more beautiful code, and it just makes us better engineers. It strikes the balance between conciseness, expressiveness and practicality, and you can do amazingly complex things with few lines of code.
Scala emphasizes scalability - large development teams, large codebases, and large numbers of CPU cores. Adapting to a multicore and distributed computing world, the Lightbend Reactive Platform pairs Scala with an industrial-strength implementation of the Actor concurrency model, called Akka.
Interoperable with Java
Since Scala is a JVM language, all of your existing Java libraries and tools can be used seamlessly, ensuring that previous investments are fully protected. Furthermore, you’re able to fully leverage your developers Java programming skills as they become proficient with Scala.
Scala programs are compiled directly to Java bytecode that runs on the extremely mature JVM, and leverages the JVM’s robust just-in-time compilation, garbage collection, and well-understood deployment techniques. The operations team won’t see a difference. Developers keep working in their familiar tools. But they’re writing code that’s shorter, faster, more scalable, more correct, and even more fun.
The Scala programming language was originally developed by Lightbend co-founder Martin Odersky's research group at EPFL.

Scala: The Simple Parts
Martin Odersky, creator of Scala, takes you on a journey to what he views as the core of the language. The core is built from a moderate number of general and orthogonal concepts that can be combined freely. The parts are simple, but the combinations can be as elaborate s one wants to make them.This keynote from Scala Days 2014 covers how, when done right, simple parts in the language lead to libraries that have clear interfaces and can be used in flexible ways.WATCH NOW

Lightbend aids in managing cable operations - CCAD
Scaling developer productivity, improving code quality and removing locking and contention were reasons that influenced CCAD’s decision to move away from the traditional Java-based stack they were using to look for more sustainable alternatives. The Lightbend Reactive Platform assisted CCAD in addressing these issues, and enabled process changes elsewhere in the organization that improved overall product quality too.READ THE CASE STUDY
