People that I work with like to have this explicit control. We don't use Hibernate, because that gives us more control. We also use jOOQ, which is a database interaction layer. If something goes wrong, that means you don't have to worry too much, because it's all in there.

There is Fluentd, which represents also all the other daemons that would sit on any of the instances. There is one application in a container, which means we don't share the instances between things. What does deployment for a typical application look like? We have CoreOS, which is coming to an end-of-life. We prefer to have compile time checks rather than runtime explosions.

We prefer to use code driven everything, not annotation driven. This is the attitude that we have in Revolut's codebase everywhere. I find Java much more readable in places. If you've read some very esoteric looking languages, or if you've seen somebody who was trying to do a very smart version of Scala or Haskell code. Especially, if I've had an amazing evening somewhere, I don't want to receive a phone call, and then I have to look at squiggly lines and I have no idea what happens. It might be counterintuitive, but there is a lot of fun in building stuff in general. I don't want certain things to be exciting. I even describe my job that I keep doing the same year in, year out. As people spend more time with computers, they prefer less creative solutions to some problems. Why? Because debugging annotation driven problems is not fun. This allows people to focus not on production issues, but instead on building and improving the codebase, and building out new features, and scaling globally and expanding the reach. All the problems that we can avoid having, if there is anything that gives us that, we're very happy. The number of developers keeps on increasing. The usage on the systems is growing like crazy. It has over 10 million users, which means it is growing like crazy.

The important facts from a software engineer's point of view is that the company is 4 years and a bit old. We have a product that's a credit card or a card, and an accompanying mobile application. What you probably know about Revolut is that it's a financial company.

What we are going to talk about is how we went from Java upgrade in the context of a particular company, because the context is always very important. We are looking at doing something similar later. Congratulations to the brave people who are on the more modern versions. Which version of Java are people on? Most of you are on the LTS editions. I also happen to run a Polish Java User Group, a conference called GeeCON, two Meetups.

Very proud to be old enough to have gone to Java 1, in time to become a Java 1 Rockstar. I'm an engineer at Revolut, which means I write code on a daily basis.
