“Real-time functionality” is rapidly becoming a requirement for software projects across many industries.
What is “real-time”, and what’s driving this trend?
Unlike typical “request/response” apps, where users have to reload a page, or press a button to get updates, real-time apps use the power of an always-on connection to receive data “as it happens.” Early real-time apps, like WebEx, Twitter, World of Warcraft, and Google Docs cost millions to build and scale. But these apps have also set the bar, and created the expectation for real-time. Real-time apps are infinitely more engaging.
Always-on, always-connected mobile devices are becoming ubiquitous, and users want to take advantage of their connectivity. And, the rapid emergence of the “Internet of Things” (aka IoT or M2M) trend is creating countless sources of real-time data streaming from connected devices all over the world. As users, we no longer want to wait for updates or a page to reload. Instead, we want to see information change “as it happens.”
Today, building real-time apps is easier, more accessible and cost effective than ever before. Real-time networks (RTNs) are quickly establishing themselves as a key part of any next-generation software stack. These real-time networks serve the purpose of making it easier for developers to not only develop real-time applications, but deploy and scale them as well. Real-time network service providers including PubNub, Pusher and Firebase offer the core building blocks needed to build and scale real-time apps.
As a result, the demand for real-time is skyrocketing, and is showing no signs of slowing down.
If you doubt the real-time revolution, just look at the apps you have installed on your smartphone today.
Real-time functionality has become intertwined in a rapidly growing mix of applications from real-time taxi dispatch, to social TV, live voting and real-time charts and graphs. You can now chat in real-time within most social and business collaboration apps.
Real-time extends to many machine-to-machine use cases as well: apps now monitor and trigger irrigation equipment in real-time, new home automation systems are embedded with code that connects to real-time networks, and cars are embedding real-time to stream their telematics data to smartphones.
So what’s this mean for the future?
Going forward, the core building-blocks found in real-time networks will become the standard way for apps to function and communicate.
The old paradigms of request/response apps will fade, along with last-generation’s software stacks built around these models.
