From Cloud Computing to Platform as a Service

Andy Piper @andypiper (MBCS CITP)

Hello I’m Andy

Reminded by my cloud-native Little Printer…

This morning!

a few things about me

Developer Advocate @ Cloud Foundry !

maker, hacker, educator, LEGO fan podcaster, writer

Open Source contributor Eclipse Project Lead (Paho / MQTT)

!

excited by “what’s next”, Internet of Things, etc.

My background

Today’s topic: Cloud!

So what do we know about “The Cloud”…?

What the heck is “The Cloud”? Citrix study (1,006 person survey)

29% an actual cloud 51% believe affected by weather 54% say they never use (but 95% turn out to do so) 20% pretend to know ... 16% know it means computer services 68% say it’s good, when explained...

1. Cloud, and how we got here 2. Platform as a Service? 3. Why Open Source will rule the Cloud

How did we get here?

1st

MAINFRAME

Automation of financial accounts

Mainframes

ISAM

c. 1960s-1980

Eras of Computing

2nd

CLIENT-SERVER & WEB

Automation of most paper processes: ERP, CRM, Email, …

Relational Databases

Mini’s & PC’s

c. 1980s-2000s

3rd

CLOUD

New Experiences New Biz Models pioneered by new Consumer Internet giants – requires a new Application Fabric

Cloud-Enabled Datacenter

New Data-fabrics

mid-2000s … now

3 layers IaaS, PaaS, SaaS

Infrastructure

Platform

SoftwareGmail, Salesforce,

Flickr, Google Docs...

Amazon EC2, Google CE, OpenStack, vSphere,

Rackspace, Cloud Stack, Eucalyptus...

Google AppEngine, Heroku, Cloud Foundry, EngineYard, OpenShift,

Azure, Apprenda...

They brought the virtualised infrastructure

Infrastructure as a Service= the new hardware

Infrastructure Clouds - consumer web companies built out according to their own needs to support Software

They brought the APIs and data (aka MBaaS) APIs - mashups, data, agility

But - still need to build & manage Platform

They brought the rapid development push ‘myapp’ -> running

They brought the business challenge data leads to advantage

Characteristics of the Cloud

• vast scale

• decreasing cost

• agility of delivery (even at scale)

• rapid data analysis and iteration (“big data”)

• innovation

To succeed where those guys have? Platform

Characteristics of PaaS

• Applications and Services (data) are kings

• Opinionated!

• De-emphasised infrastructure / hardware (VM, kernel, disk, network etc)

• An “operating system” for IaaS

Rumours of the demise of PaaS are greatly exaggerated…

Why Open wins

An important year in software

1991

Hello everybody out there using minix - !

I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones.

21+ years later: Linux has won

Linux runs everywhere (even old versions, on crashy airline entertainment systems...)

#P0WN ALL TEH

GADGETZ !

It runs on Windows Azure! Jun 2012, w. Canonical

Linux is ubiquitous

(but often invisible)

It works.

No single language to “rule them all”

Data gets bigger (and faster, and needs analysis, and SCIENCE)

Composability is key

An Operating System for the Open Cloud

Multi-IaaS, Multi-Framework, extensible…

Open & public from the start Code all on Github

All about Choice

Infrastructure !Clouds (CPI)

Runtimes and !Frameworks

Data Servicesand APIs

composability is key…

The 2014 Cloud Forecast?
