The AndPlus Guide to IoT Frameworks

May 3, 2022 6:43:38 PM

IoT frameworks exist to help you create IoT solutions without doing all your own development. Some simply give you a structure to work inside; others offer you enterprise-level data analysis and control — for a price. Choosing the right one is a key part of the success of your IoT project.

In this post, we’ll briefly cover what a framework is and how they work, then give an overview of the main open-source and proprietary frameworks. If you’re relatively new to the IoT, here are some resources to help you orient yourself:

IoT 101

IoT is the Internet of Things. It refers to groups of connected devices that communicate with each other through technologies like Bluetooth and RFID, and are connected to the internet. It’s a complex topic that’s growing in importance and popularity, so check out our guides to:

What are IoT frameworks?

IoT frameworks, sometimes referred to as IoT platforms, exist to deal with the open-ended complexity of building IoT solutions. IoT solutions can include:

  • Hardware
  • Software
  • Operating systems, middleware, and firmware
  • Communication
  • Network architecture
  • Security and firewalling

Ready? OK, let’s develop an application.

This is like all unstructured processes: if you have a lot of resources and expertise it’s very freeing. You can make anything you want. But if you’d like to get to the value of IoT without becoming an expert in it, it’s difficult and obstructive. The IoT is where computers were in the 80s or the internet was in the 90s. Adoption is skyrocketing, the value is clear, but the route to it is not marked out in a way that’s easy for businesses to relate to and use.

Enter frameworks.

Frameworks hem you in and support you, making it easier to make decisions between fewer options because you know the results will work. They’re often offered by companies that are already players in the industry — Google, Cisco, and Amazon offer frameworks, for instance.

However, other, open-source frameworks have been put forward by groups of users seeking an environment to develop applications and solutions for their own organizations. Again, this makes sense: the most-used OSs for IoT devices are Linux and smaller, often Linux-descended open-source tools. Even some of the specialized proprietary tools are maintained by their communities under non-profit licensing.

Open-source frameworks aren’t always free — that’s a misconception. Instead, they’re so called because their source code is available for inspection by you and others. Having many eyes on code often (though not always) means it’s better, and open-source applications are frequently more secure than their proprietary analogs.

What’s in a framework?

Frameworks typically include:

  • Hardware devices, including sensors, controllers, micro-controllers, and other hardware elements
  • Software applications that configure controllers and operate them remotely
  • Communications systems and options — Bluetooth Low Energy or RFID
  • Applications layer, running over devices and networks to deliver results

Thus, if you’re working with a framework, you should have an easier time building a solution that delivers what you want. However, you still need to select an appropriate framework.

Let’s start by looking at the open-source frameworks.

Proprietary frameworks

Again, these aren’t proprietary in that they cost money to use: as we’ve seen, open source frameworks aren’t always free, or even low cost. Proprietary frameworks keep their code to themselves, and are typically owned by larger companies like Amazon and Cisco. We’ll quickly give the rundown on the most popular proprietary platforms.

Amazon Web Services IoT

AWS IoT documentation: https://docs.aws.amazon.com/iot/

Amazon Web Services is the behemoth of the internet. Its servers power around a third of all cloud services, effectively powering more of the internet than any other entity.

The company’s IoT offering gives users access to data management and analytics tools and cloud services, including enterprise-level access control, encryption and auditing. It also delivers device management for large fleets of devices and is easy to scale. There are even additional hardware modules to turn already-embedded devices into IoT devices and connect them to your network. Unsurprisingly, AWS is favored by larger companies with deep pockets. AWS features the Volkswagen group prominently in its case studies. However, they also have plenty of smaller customers.
