Java: Key Benefits

Time-to-Market. Java has a well-designed reach API, large ecosystem of well-tested libraries and frameworks for any use case. It is very easy to design, implement and deploy your application.

Distributed computing. Java is designed as a distributed language and allows to involve several computers on a network working together. On top of that Java has the whole ecosystem of Big Data processing frameworks like Hadoop, Spark, Sockets, Remote Method Invocation (RMI), Multicast Sockets, Kafka, Message Passing Interface (MPI).

Platform-Independent. Though with the introduction of Containers this benefit lost its importance in some cases it is still a valuable benefit.

Why Do You Need Java After All?

Reduced Time-to-Market

Java is a mature object-oriented language, which allows creating modular programs and reusable code. The intuitive set of APIs comes as another time-kicker. Programming in Java tangibly shortens the overall development time and cuts the costs.

Platform Independence

Java is a beast of many faces and allows to run the same application on different systems – an indispensable point for a modern software solution. In fact, Java succeeds at this point as it is independent on both levels – source and binary.


Developing high-load applications using Java is easier and more efficient as the technology allows programs to perform several tasks simultaneously within a single program.
