On our way to the Cloud: History

Coding Building

And then profit deploy?

Deployment isnot my problem

Customer’s Operations Department; photo-shoot

It is MY production system

Bare Metal DeploymentDIY

YAGNI: You Ain’t Gonna Need It (cloud)so DYI: Do It Yourself

Bare Metal Deploymentgone wrong

YAGNI / DIY meets scaling

The boss POV

“What are you doing?”

“Fine :-)”

Infrastructure as a Service

Virtualizyfy!

Intalio HQ circa 2008[Boss]: Let’s move on the cloud.No need to worry about:• Deployment• Support for multiple OSes• Support for many SQL database• Backups• Scaling

Cloud Or snake oil?

Marketing `delivers`the cloud right away

Embarrassed engineer:it is still software

IaaS: AWS/EC2

DebianPackage

Repository

Ubuntu VM on AWS/EC2

The boss POV

“Too complicated”

IaaS Reality Check

Did the promises pay?• Deployment• No need to support multiple OSes• No need to support many SQL databases• Backups• Scaling

IaaS Reality Check

“I still have a job and it is full time.But the focus is not right”

Choosing a PaaS

Make a requirement matrix:

• The type of clouds: public, private, hybrid

• The required runtimes and databases

• The licensing

Open Source PaaS: Cloud Foundry

Intalio is here at the moment:small impact on our apps

lots of work on customizing the PaaS

NoOps’s Hello World

• Hello World in Ruby / Sinatra

• Read the VCAP_PORT

• vmc <target>

• vmc <login>

• vmc <push>

• vmc instances <num>

Inside The PaaS

Nginx - Load Balancer - Reverse Proxy

Nginx - Lua: Router

Droplet Execution Agent

•Distributed Architecture on a PaaS

Software is distributed now

Best in class cloud architectures:

many distributed services run by many apps

multiple databases

Monolith turnedswiss army knife

Challenges:• maintenance is hard• at $2200USD a piece it is costly to scale this

Game: find the original app

Big Application

Overloaded Database

Deploying a set of appsand DBs with a PaaS
