<h2>Overview</h2>
The Internet of Things, or IoT for short, is a promising branch of technology that together with Big Data is conquering the digital world now. The idea of smart interrelated gadgets and consumer electronics able to work independently has been evolving since the end of the 20th century. This technology has successfully resulted in a highly-developed far-reaching system of middleware between the devices and user applications. The universal popularity of the IoT strategy is easily explained by the fact that there are billions of devices worldwide in all aspects of human life: medicine, industry, commerce, farming, lifestyle, to name just a few.

You should bear in mind, though, that open source solutions are not totally equal to free software. The terms may mean the same and are used interchangeably sometimes. However, open source software (OSS) goes both ways: it can come to you at no cost as well as offer you quite expensive price tags. The difference lies in its open nature of the software development approach as it allows side code enthusiasts to easily join the programming process.

Needless to say, the majority of businesses treat <a href="https://www.byteant.com/blog/">emerging tech trends</a> as an invaluable asset with an eye on their subsequent monetization. Quite obviously, some organizations opt for having the competitive IoT-backed solutions integrated with their processes, like these actionable use cases for Automobile and Sports industries. Some decide to double down on buying out or creating their own open-source platforms to maximize revenues. Either way, it leads us to the exponential increase of software development initiatives driven by IoT. Here’s a list of some facts that just add fuel to the fire of IoT-based potential. 

- Gartner forecasts the rapid growth of connected things from 14.2 billion in 2019 and 20.4 billion in 2020 up to 25 billion by 2021.
- Many advanced technologies, like AI, ML, clouds, IoT, blockchains, are developed within open software platforms. In 2018 IBM buys Red Hat and Microsoft buys GitHub – the homes of contemporary software innovations for all branches of business.
- According to the Red Hat report, 77% of surveyed IT leaders plan to expand the usage of open source solutions in the next 12 months. 75% of respondents consider it very or extremely important.
- Open source-based business solutions are among the most discussed technological topics of 2019 alongside with cryptocurrency and self-driving cars.
- Here is an in-depth guide on how open-source software is used by major organizations like Google.

<h2>Open-source IoT frameworks to consider</h2>

Many companies look for the out-of-the-box open-source platforms while trying to find the best IoT tools that can provide robust analytics and interoperability between their connected devices. Let’s get a brief overview of the 5 most deployed open source IoT frameworks to see if they meet your business needs.

<h3>1. DeviceHive</h3>

Price: from $ 650 /unit
Documentation: https://www.mathworks.com/help/thingspeak/

ThingSpeak is a relatively young IoT platform that tightly collaborates with MathWorks. This gives the possibility to leverage from timely MATLAB data analysis from numberless sensors. The platform comprises:

- live data streams aggregation and analytics;
- data recording from public channels to be further used in newly created private channels;
- assignment of  public channels to share data;
- visualization of collected data;
- updates of channel feed via the REST and MQTT APIs;
- MATLAB® online analytical tools for exploring patterns and relationships;
- TimeControl function that enables event-triggered alerts.
To sum up, this framework’s biggest advantage is that it really makes things communicate with you.

<h3>3. Mainflux</h3>

<h3>Utilizing OSS: Some benefits and drawbacks explained</h3>

At first glance, the IoT tools mentioned above may seem quite similar and enlist homogeneous features but these platforms can come in handy going far beyond. Alternatively to proprietary software, open-source technologies are completely customizable and scalable – as the code is open it can be adjusted and modified to the businesses' needs. OSS allows developers and enterprises to move between different frameworks without complications – the necessary toolkit provided.

With a great number of automated protocols and functions, open-source frameworks save much time for IoT engineers and tech-professionals. This IoT solution is better for handling deployment flexibility issues and reducing expenses. Being of the major priority, data privacy and security is the main standpoint of any business, so you may choose from diverse open-source framework vendors worldwide.

There are still some challenges you can face on this far-reaching way:

- Open means free access, i.e. contributors are not always specialists;
- Secure maintenance is always vulnerable;
- Data privacy gains a growing legal interest;
- A number of best open source platforms may cost a fortune;
- Bugs happen;
- The set of available standard features doesn’t fit all your business needs;
- Open source IoT platforms are not for a mediocre user.

Whatever you are looking for, remember that you may choose any way <a href="https://www.byteant.com/internet-of-things-development-services/">to materialize your business concepts</a> and you are free to change your mind at any point.
