Buzzwords: Microservices, Containers and Serverless at Goto Chicago

Goto Chicago Dave Speaking

It was an honor to give a talk on the future of Serverless at goto Chicago, an enterprise developer conference running from May 24 to 25, 2016. As you can see from the full room, containers, microservices and serverless are popular topics with developers, and this interest extends across a wide swath of back-end languages, from Java to Ruby to node.js. Unfortunately, the talk was not recorded, so I’m providing these notes (and my slide deck) for those who could not attend.

The Evolution of Deployed Applications

Before we look forward into the future of Serverless, let’s look back. We’ve seen a historical evolution in deployed applications at multiple different levels. Whereas before the unit of scale was measured by how many servers you could deploy, we’ve moved through rolling out virtual machines to the current pattern of scaling our containerized infrastructure. Similarly, we’ve seen a shift from monolithic architectures deployed through major releases to containerized, continuously-updated microservices. This paradigm is Iron.io’s “sweet spot,” and we’re leading the enterprise towards a serverless computing world.

Get a Job, Container: A Serverless Workflow with Iron.io

My previous post, Distinguished Microservices: It’s in the Behavior, made a comparison between two types of microservices – real-time requests (“app-centric”) and background processes (“job-centric”). As a follow up, I wanted to take a deeper look at job-centric microservices as they set the stage for a new development paradigm — serverless computing.

Of course, this doesn’t mean we’re getting rid of the data center in any form or fashion — it simply means that we’re entering a world where developers never have to think about provisioning or managing infrastructure resources to power workloads at any scale. This is done by decoupling backend jobs as independent microservices that run through an automated workflow when a predetermined event occurs. For the developer, it’s a serverless experience.

Distinguished Microservices: It’s in the Behavior

This post originally appeared on DZone

Microservices is more than just an academic topic. It was born out of the challenges from running distributed applications at scale; enabled by recent advancements in cloud native technologies. What started as a hot topic between developers, operators, and architects alike, is now catching on within the enterprise because of what the shift in culture promises — the ability to deliver software quickly, effectively, and continuously. In today’s fast-paced and ever-changing landscape, that is more than just desirable; it’s required to stay competitive.

Culture shifts alone are not enough to make a real impact, so organizations embarking down this path must also examine what it actually means for the inner workings of their processes and systems. Dealing with immutable infrastructure and composable services at scale means investing in operational changes. While containers and their surrounding tools provide the building blocks through an independent, portable, and consistent workflow and runtime, there’s more to it than simply “build, ship, run.”
