Iron.io is an enterprise-grade development platform for

building highly scalable event-driven applications

➔ Operating in production since 2011 ➔ Team of 50+ headquartered in San Francisco

➔ 5,000+ active developer accounts ➔ 600+ customers from startups to enterprises

➔ Millions of containers processed per day ➔ Thousands of servers abstracted at any time

Businesses are on the hook to deliver

continuous innovation to their customers

Developers are on the hook to deliver

continuous innovation to the business

➔ Faster time to market

➔ Shorter release cycles

➔ Resilient systems at scale

➔ Optimized for performance

➔ Cost efficient scalability

➔ Minimal operational overhead

➔ No technology lock-in

We demand so much from our teams today yesterday

How can we empower our developers to be

more productive within reasonable bounds?

The ways software is built and shipped has evolved...

Architecture

Infrastructure

Monolith N-Tier Microservices

Servers Virtual Machines Containers

along with how the systems and applications operate and behave...

What happens when we bring

all these modern concepts together

where each of their true value lies?

Microservices enable independent workloads

Containers enable a portable runtime

DevOps best practices enable automated workflows

Event-driven computing enables reactive invocation

Independent + Portable + Automated + Reactive = ??

SERVERLESS!!

Let’s first dispel a few myths about Serverless

“There’s still servers… they’re just

managed by somebody else”

“A Serverless architecture is

no different than PaaS”

“Serverless is leading us to

the NoOps revolution!”

An application architecture that enables single purpose jobs

to be packaged independently as portable units of compute

that execute through a fully automated pipeline

when a predetermined event occurs.

My attempted definition of “Serverless”

Microservices

Containers

DevOps

Event-driven

When does it make sense to apply these patterns?

Pushed

Long Running

Requested

Load Balanced

Elastic

Uploaded

Ephemeral

Triggered

Queued

Concurrent

12-Factor App Serverless Job

Making a behavioral distinction

Common use cases

Backend Transactions

➔ Processing a credit card

➔ Sending an email

➔ Bots, bots, bots!

Batch Processes

➔ Multiple file processing

➔ Crunching a big data set

➔ Multi-step workflows

Data Pipelines

➔ Processing machine data

➔ Service to service integrations

➔ Custom CI/CD pipelines

Scheduled Jobs

➔ Daily notifications

➔ Web crawling

➔ Database scrubs

Systems Applications Manual

Pub/Sub Stream Schedule

Potential event sources

Be careful: events have a tendency to pile up in real world application scenarios

How does this impact the development process?

The Serverless development experience with Iron.io

There’s no need for you to provision the resources, configure the systems, or manage the components

The entire workflow is fully automated without any human intervention

Developer empowerment comes from effective abstraction further up the stack

Being a platform means knowing where to draw the lines...
