5 Data Models for IoT

Apache Cassandra is a rock-solid choice for managing IoT and time series data at scale. The most popular use case of storing, querying, and analyzing time series generated by IoT devices in Cassandra is well-understood and documented. In general, a time series is stored and queried based on its source IoT device. However, there exists another class of IoT applications that require quick access to the most recent data generated by a collection of IoT devices based on a known state. The question that such applications need to answer is: Which IoT devices or sensors are currently reporting a specific state? In this blog post, we focus on this question and provide five possible data modeling solutions to efficiently answer it in Cassandra.

Introduction

The Internet of Things (IoT) is generating massive amounts of time series data that needs to be stored, queried, and analyzed. Apache Cassandra is an excellent choice for this task: not only because of its speed, reliability, and scalability but also because its internal data model has built-in support for time-ordered data.

Zero Trust Security Model to Safeguard Software Apps

We've all heard a lot about digital transformation and how it affects the IT world. Each of these technologies, whether it's big data, the Internet of Things (IoT), or cloud computing, has made a significant contribution to a range of enterprises. Few people, however, talk about the complexity they add, especially in the context of business network infrastructures.

The fences are crumbling, and there is a hazy peripheral that is causing security concerns.

Steam Raspberry Pi Streaming: How to Install the Steam Link App For Raspberry Pi

While loads of digital video game vendors exist, Valve reigns supreme as arguably the most popular. Its Steam Link hardware debuted in 2015 as a means of streaming Steam games from a PC over a home network. This in-home streaming feature allowed for playing video games on a TV or projector for a console experience with PC gaming. However, in 2018, Valve halted production of the Steam Link. Alternatives such as the third-party Moonlight or Parsec for game streaming exist. But Valve released its own Steam Link app for Android, as well as the Raspberry Pi 3. Learn how to install the Steam Link app for Steam streaming on the Raspberry Pi 4, 3, or 3 B+ for the ultimate Raspberry Pi gaming build!

Top IoT App Development Trends in 2021

More Focus on Container Technologies in IoT Platforms

Gartner projects that over 75% of global organizations will be using containerized apps in production by 2022. So far, container technologies have been part of traditional enterprise IT environments and cloud architectures. Recent developments in industrial IoT platforms and the increased demand for vendor-neutral IoT technologies, however, have made containers increasingly relevant for the Internet of Things. 

Defining Containers

What is a container? It is a lightweight virtualization technology that includes an entire runtime environment. This means an application and all its dependencies, plus the libraries and configuration files required to run the application. Container technologies help you abstract differences in operating systems and underlying infrastructures. This is why they are often embedded in IoT platforms so that you can connect to any device and make virtually any machine or piece of legacy equipment IoT-ready.

Popular IoT Development Platforms: 2021 Edition

The Internet of things or IoT is a real trend that is apparently gaining popularity among other things. We all might have heard about the buzzword ‘IoT’ at some point in our lives either from a friend, a blog post, or people walking by on a sidewalk. IoT is all about 'physical devices connected to the internet,' in other words, ‘Simply, the Internet of Things is made up of devices — from simple sensors to smartphones and wearables — connected together,’ Matthew Evans, the IoT program head at techUK describes IoT in a nutshell.

The Brief History of IoT

The year 1999 is considered huge for IoT. The term ‘Internet of Things' was coined by Kevin Ashton, executive director of the Auto-ID Center. According to British tech pioneer, Kevin Ashton,

Scaling Salesforce Apps Using Heroku Microservices

This is the ninth article documenting what I’ve learned from a series of 13 Trailhead Live video sessions on Modern App Development on Salesforce and Heroku.  In these articles, we’re focusing on how to combine Salesforce with Heroku to build an “eCars” app—a sales and service application for a fictitious electric car company (“Pulsar”).  eCars allows users to customize and buy cars, service techs to view live diagnostic info from the car, and more. In case you missed my previous article, you can find it here.

Just as a quick reminder:  I’ve been following this Trailhead Live video series to brush up and stay current on the latest app development trends on these platforms that are key for my career and business.  I’ll be sharing each step for building the app, what I’ve learned, and my thoughts from each session.  These series reviews are both for my own edification as well as for others who might benefit from this content.
