Applying configuration properties to application components
Working with Spring profiles

Do you remember when the iPhone first came out? A small slab of metal and glass hardly fit the description of what the world had come to recognize as a phone. And yet, it pioneered the modern smartphone era, changing everything about how we communicate. Although touch phones are in many ways easier and more powerful than their predecessor, the flip phone, when the iPhone was first announced, it was hard to imagine how a device with a single button could be used to place calls.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
