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

This post originally appeared on DZone

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.”

How to Bake Your Own Pi

Baking Your Own Pi

It’s 3/14, and that means it’s international Pi day! A day where we rejoice over the transcendental number that seems to be everywhere.

So, why am I writing about pi on the Iron.io blog? It turns out pi is the best (read: the absolute best!) way to test out computers. It’s sufficiently random, requires large amounts of memory, CPU, and is easy to check.

I first learned about this aspect of pi while reading the book Heres Looking at Euclid. There, I also learned that Pi beyond 40 digits or so isn’t all that useful. So, why do we know pi into the billions of digits? To quote the many time world record holder,

“I have no interest as a hobby for extending the known value of pi itself. I have a major interest for improving the performance of computation. [..] Mathematical constants like the square root of 2, e, and gamma are some of the candidates, but pi is the most effective.”

How To Make Pi

I’m on board! I want to make Pi, myself. If Pi is a great way to test any computer, why not use it to test first-class distributed computing solutions, like IronWorker?

Humans have known about Pi for a while. Which is part of what makes it a great computation. We have multiple recipes for baking the same dish. That means it’s easy to check our work (by comparing two algorithms).

So, what goes into pi? How can I cook this dish? Let’s check out a few of the best recipes. Continue reading “How to Bake Your Own Pi”

GoSF: The 1.6 Release Party at Docker HQ

Go 1.6 Launch Party

Lightning, thunder, and even hail swept through SF yesterday. But, that didn’t deter hundreds from hustling to Docker’s HQ for the Go 1.6 release party! GoSF received over 470 signups, a nice sum for a relatively young language.

Yesterday’s launch party boasted trivia, stuffed gopher giveaways, and a limited run T-shirt from Iron.io’s Bruce Lu. Oh, and as always there were some great talks.

Video of the talks will also be online soon! For the impatient, we’ve also included summaries and slides of last night’s talks below. Continue reading “GoSF: The 1.6 Release Party at Docker HQ”

SF Rails: Reduce Complexity and Simplify Code

SF Rails: Reduce Complexity and Simplify Code

Last night we swung by the snazzy DevBootCamp offices. Our goal? To learn from the fine folks joining us at the SF Rails meetup.

The topics included DCI, a comparison of static site generators to traditional CMS, and how workers are better fit than functional programming for reactive infrastructure.

Heady stuff! Keep reading for a preview of each topic, and a link to each speaker’s slides. Continue reading “SF Rails: Reduce Complexity and Simplify Code”
