Digitization has changed the business model in companies. Today, every market analysis is dependent on data. As a result, the rate at which data is being generated is outpacing our analysis capability. Hence, big data analysis is in place with high-end analytic tools, like Hadoop. Hadoop is a Java-based programming framework with high-level computational power that enables us to process large data sets.

On the other hand, after the Internet, the next thing to take the world by storm would be the Internet of Things (IoT). This technology is based on artificial intelligence and embedded technology. This new wave of technology is meant to enable machines to partake in human-like performance. However, the implementation of an embedded system needs many considerations; and, here comes the role of Java in IoT.

Being in the technology space for more than 20 years as a trusted platform for development, Java has never been outdated. Furthermore, its role is ubiquitous — even with the latest technology inventions.

In this blog, we will discuss the potential of Java in big data and IoT.

What Does IoT Do?

IoT consists of technology designed to collect and manage massive amounts of data from a vast network of electronic devices and sensors, then processing the collected data and sharing it with other connected devices or units to make real-time decisions. Basically, it creates intelligent devices. An example of these intelligent networking systems is the automated security system in a house.

However, enabling the IoT would need programs that help the device to easily connect with other devices and to maintain the connectivity all around the system. Here, Java comes into the picture with its networking programming capability.

Role of Java in IoT

Here are the features of Java, which play critical roles in developing an IoT system.

Platform Independence

Platform independence is an important feature when you are developing an IoT system. During the development of an embedded application, you need to consider the following factors:

  • Processor
  • Real-time operating system
  • Different protocols that will be used to connect the devices

Java ME abstracts all of the above factors. Hence, the developed IoT application can run across the many different devices without changing the code of those applications. It helps to implement a write once and prototype anywhere (on different types of hardware platform) facility. As IoT mainly handles embedded systems, developers need to use the software on different chipsets or operating systems, as per the requirements.


Portability over the network is one of the primary reasons for choosing Java for IoT development — almost all devices, from your desktop computer to your mobile phone, use Java. Also, with its networking capability, it is an integral part of the Internet and makes it a good fit for IoT.

Easy Accessibility With the Best Functionalities

A developer can easily learn Java, and with its best level of object-oriented features, it provides the best level of services in an application. For example, security and scalability are two important parameters in the industry while dealing with IoT devices, and Java meets that requirement. With a huge ecosystem already in place, Java makes itself more suitable for the IoT. Hence, developers with advanced Java knowledge are working on innovative IoT solutions to create a connected digital world.

Extensive APIs

Java offers its users the advantage of using an extensive list of APIs, which they need to apply rather than rewriting during the making of an embedded application. It makes Java a perfect choice for IoT programmers.

Flexible and Easy to Migrate

One of the primary reasons IoT programmers gravitate towards Java is because of its flexibility and virtual availability everywhere. Essentially, you can do anything with Java. The migration capability of any Java application is high. The reason behind it is, if an application is developed using Java, there will not be many issues during the migration to a new platform, and the overall process will be less prone to error.

What Are the Benefits of Using Java for IoT?

When we embed Java for IoT, as a user, we receive numerous benefits that ultimately reap in business benefits along with technical enhancement.

Here are some of the major benefits:

  • Higher resource availability — Being in a technology space over a long period of time, Java has built up a strong community that consists of millions of developers around the world. It is a diverse ecosystem, and with a strong community back up, it is easier for a developer to learn Java than any other language. Hence, it helps to meet the goal of achieving a connected system.
  • Enhanced device performance — In IoT, mainly, the Java-embedded code is used, which helps create an enhanced information exchange among devices on a timely basis and makes devices more integrated.
  • Enhanced product life-cycle due to high adaptability — With Java, a product has the ability to upgrade itself according to the business requirements and changes coming up in the market. Moreover, it manages itself without any glitch. Therefore, the overall product life-cycle enhances with the use of Java.
  • Increased marketability — Since the product lifecycle gets increased with the reusability of modules, the overall market credibility of the product increases automatically.
  • Reduced support cost — As Java Embedded provides the ability to auto update and manage a product, the support cost gets reduced significantly.
  • Secure and reliable — With the enhanced security feature of Java, any IoT device will gain security and reliability assurance over the Internet.

What Is the Role of Java in Big Data?

When we talk about big data, the first thing that comes to our mind is what does it actually do? Well, big data deals with enormous data sets, either formatted or unformatted, and processes them to provide a valid output to the businesses in the required format. Here are few main purposes of big data:

  • To process a huge set of data and gain insights into a trend
  • To use processed data for machine learning purposes and create automated processes or systems
  • Using big data for complex pattern analysis

For the functionalities mentioned earlier, tools are predominantly used. Some of the popular tools are Apache Hadoop, Apache Spark, Apache Storm, and many more. Most of these tools are Java-based, and Java concepts are widely used for data processing.

How Big Data and IoT Are Interrelated

As IoT continues to grow, it has become one of the key sources of an infrequent amount of data. The data may be sourced from hundreds to thousands or even larger numbers of IoT devices as random data. This huge set of data also needs analysis through big data. Thus, there is an interdependency of both the technologies where Java works as a common platform.

What Is the Future Role of Java in Big Data and IoT?

IoT is triggering millions of devices to connect online, which is resulting in more data than ever before. These massive data sets need large amounts of storage and management. For this purpose, big data technologies must be augmented to handle data effectively. Interestingly, technology giants, like Google and Apache, are contributing to more libraries for technology advancement. As we have discussed the role of Java in big data and IoT, it is expected that Java development will play the more aggressive role moving forward.

Overall, Java has always been considered a popular and useful technology, while also being a trusted platform when compared to all other programming languages on the market. Though there are numerous programming languages in place with easier interfaces, like Pig, Ruby, and many more; still, people show their gravity towards Java. As a result, the numbers of Java programmers are increasing every day.

Whether or not the technologies like big data and IoT change rapidly, the role of Java in big data and IoT will always remain.


The bottom line is – Java is everywhere. If you want to walk with the changing industry trends, then Java is not the ultimate answer for achieving a promising career. You need to ramp up the latest technologies, like big data, machine learning, IoT, Cloud, or similar technologies.
