When we talk about "the cloud," there's more than just the Internet: there's public cloud, private cloud, hybrid cloud, and even multi-cloud. As with any architectural decision, each of these distinct locations require careful consideration when you're building an application. Giorgio Regni is the co-founder and CTO of Scality, and he's going to demystify the different types of clouds, and explain why you might choose one over the other.

We're all familiar with using data and analytics to monitor the performance of our applications, but Kevala is applying those software fundamentals in new industries. Kevala tracking energy grids in cities and neighborhoods, to map the ways that power is produced, distributed, and consumed. The technology has the potential to decarbonize the energy grid, or at least, offer lower energy prices for distributors and consumers. Kevala's engineering lead, Emmanuel Levijarvi, and one if its software engineers, Teddy Ward, talk about how Kevala works and the tools they rely on to reliably predict energy utilization.

Docker has emerged as an extraordinarily popular way to safely and predictably deploy applications. But because of its rapid evolution, changing business targets, and technical composition, it can still be a bit daunting to understand when to use it versus other container runtimes, let alone the task of managing it via Kubernetes and other orchestrators. This episode takes a deeper look at the components of Docker, with a strong emphasis on developer productivity in smaller organizations, not massive enterprises. Bret Fisher is our guest, and as a certified Docker expert—a Captain, actually—his job (and passion) is to share his technical expertise.

Legacy code is everywhere. Software is also being modified, whether as a result of new requirements, new security issues to patch, or new hardware and operating systems to target. Whether you're working with code from three months or three years ago, the upgrade process doesn't need to be painful. Joe Leo is here to help us conquer our fears of fixing legacy systems. He's the CEO of Def Method, a software consultancy in New York. He'll teach us the effective strategies he's learned over his years of experience with upgrading plenty of code he didn't write. We're also going to give away a 40% discount code for Joe's new book on Ruby development!

Developers can't help themselves from implementing their ideas with every new language and framework that comes along. Sometimes, we discover that the itch we wanted to scratch was a problem for many other teams, too. Ben Curtis found this out when he built Honeybadger, an exception monitoring service. It started as a side project which he eventually turned into a full-time business. He guides us through this journey, and the discoveries he made about work-life balance along the way.

We're fortunate to live in an age with access to nearly unlimited resources for information. Sometimes, though, reading a tutorial isn't enough: you've got to see how someone builds something to fully grasp it. Geoffrey Grosenbach certainly thought so. Back in 2006, he built PeepCode and sold screencasts guiding watchers through his work building Ruby on Rails apps. He's currently at Hashicorp as their Director of Product Education. He joins Mike Mondragon on this episode to talk about launching a business aimed at developers, and how he learned to teach others.

When you're one of the largest telecommunications companies in Canada, you're responsible for building and maintaining services that can handle a volume of data many times greater than the average web server. Julián Duque had a chance to sit down with Luca Maraschi, a chief architect at TELUS Digital, during NodeConfEU. On this episode, they talk about the frameworks and tech stack Luca has chosen to build the service mesh which facilities data flow between their microservices and clients.

Heroku applications big and small run on dynos, virtualized Linux containers fine-tuned to execute your code. As the load on a server increases, you must add dynos to keep up with demand—but how do you know how many more to add? And how can you be sure that you are saving costs by reducing the amount of dynos after spikes in traffic settle? To solve that problem, Adam McCrea developed Rails Autoscale, a Heroku add-on that auto-scales Rails apps hosted on Heroku. He'll talk with Corey Martin about how he came up with the idea, how he built it, and how he got word out amongst his network to make it a must-have add-on.

Chris Castle has a two year nephew who, like most two year olds, likes pushing buttons—especially ones that turn lights on. When a Christmas tree appeared a few weeks ago, and lights were put up, he was very excited. At the same time, Chris was experimenting with Puck.js, a programmable low-power bluetooth button, and had a brainwave—he could combine his nephew's love of buttons and of lights. A true Christmas miracle.

Errors are a fundamental part of the programming experience. Learning how to receive and react to them, as well as responding to the user who may have encountered one, is essential to building a great application experience. Ruben Bridgewater, a core member of the Node.js team, talks us through various error handling strategies, both those that are specific to JavaScript as well as those applicable to anyone building a production-grade service.
