Cloud Platforms allow developers to take risks, become more agile and focus on building business value instead of infrastructure

@chanezon

Very freely inspired from

... the story of my grandfather and a few years as an Enterprise consultant in

France before moving to California

My grandfather, missed the transition from Radio to TV in the 1950’s

2010

- George became CIO

What happened while

George was playing Golf

Dreams Of my childhood

33

Accelerando / Singularity, in a Galaxy far far away

§Even if we automate ourselves out of a job every 10 years§ ...I don’t think the singularity is near!

34

Moore's Law is for Hardware Only

§Does not apply to software§Productivity gains not keeping up with hardware and bandwidth§Writing software is hard, painful, and still very much a craft

35

Predictions

“The future is already here — it's just not very evenly distributed” William Gibson

Architecture Changes: 60’s Mainframe

Architecture Changes: 80’s Client-Server

Architecture Changes: 90’s Web

Architecture Changes: 2010’s Cloud, HTML5, Mobile

Cloud Stack - History

§What does cloud mean, 4 main angles• Software 1994 Netscape• Infrastructure 2002 Amazon AWS• Platform 2008 Google• Development now!

45

§ Industrialization of hardware and software infrastructurelike electricity beginning of 20th century

§But software development itself is moving towards craftmanship

Cloud started at Consumer websites solving their needs

• Google, Amazon, Yahoo, Facebook, Twitter

• Large Data Sets

• Storage Capacity growing faster than Moore’s Law

• Fast Networks

• Vertical -> Horizontal scalability

• Open Source Software

• Virtualization

• Cloud is a productization of these infrastructures

• Public Clouds Services: Google, Amazon

• Open Source Software: Hadoop, Eucalyptus, Ubuntu, Cloud Foundry

Google research papers: good predictor of where BigData is going

• Horizontal scalability 2004: Map/Reduce (Hadoop)

• NoSQL 2006: Bigtable (Mongo, Cassandra, HBase, Riak)

• Real Time analytics 2010: Dremel, BigQuery (Impala)

• Horizontally Scalable SQL 2012: Spanner/ Amazon Redshift

48

Infrastructure

IaaS/Virtualization getting mainstream

§AWS, Joyent, Rackspace,...§Open Source projects: OpenStack, CloudStack, Eucalyptus§Automation: Chef, Juju, Cloud Foundry BOSH§ Inside the Firewall, Virtualization: VMware, Microsoft, Xen, KVM§ 60% of workloads are virtualized in 2012§Easy to provision, manage instance...BUT§Still need to manage backups, software stacks, monitor, upgrades

49

With Infrastructure, you still need to build your own platform

§Need to build a distributed platform on top of you infrastructure§Story of the AWS meltdown from last summer

• http://blog.reddit.com/2011/03/why-reddit-was-down-for-6-of-last-24.html

• http://www.readwriteweb.com/cloud/2010/12/chaos-monkey-how-netflix-uses.php

• http://news.ycombinator.com/item?id=2477296

• http://stu.mp/2011/04/the-cloud-is-not-a-silver-bullet.html

§Twilio, Smugmug, SimpleGeo survived it because they built their own distributed platform on top of IaaS

§Enterprise customers want to consider Infrastructure like CDNs• Multi Cloud usage

• Based on Open Source de facto standards, or full standards whenever that happens

50

51

Platforms

Platforms

§Raise the Unit of currency to be application & services instead of infrastructure

§Google App Engine, Cloud Foundry, Heroku, CloudBees, Amazon Elastic Beanstalk, Microsoft Azure, AppFog

§Single or a few languages, services

§Start of Multi language Polyglot platforms

§Enabler for Agile Developers -> Create Business value faster

§ Lack of standards: risk, vendor lock-in

§Enterprise needs:•Control, customizability

•Private/Hybrid Cloud

•Avoid lock-in

52

Agile Development Processes

Agility as a survival skill

§Consumer software is becoming like fashion

•Phone apps, social apps, short lifetime, fast lifecycles

•A/B testing

§Enterprise

•Clay shirky situational apps

§Kent Beck, Usenix 2011 Talk, “Software G-Forces: the effects of acceleration”change in software process when frequency grows

§Cloud Platforms enables an Agile culture, driver for innovation

•Scalability is built in the platforms

•Can iterate faster

•Focus on design

§Cloud Platforms lets developers focus on driving business value

54

Main Risk: Lock-In

Cloud Foundry BOSH is an open source tool-chain for release engineering, deployment, and lifecycle management of large scale distributed services• Prescriptive way of creating releases and managing systems and services• It is not a collection of shell scripts, not a pile of Perl

Built to deploy and manage production-class, large scale clusters• Production grade Cloud Foundry clusters: 500+ VMs, 40+ jobs, 75+ packages •Multi-node, multi-tier, complex clusters: e.g., our Gerrit/Jenkins Cluster

Built for devops usage and scale by a crack team of veterans• A project, not a product: command line interface, YAML, etc. • Continuous improvement, iterative development, rough edges

Lessons for Developers

Predictions

•Software is becoming like fashion, design rules•Welcome to Babel, use the best tool for the job, embrace multiple language & heterogeneity

•Our jobs will change, build yourself out of your current job•Sysadmin jobs will morph, there will be less of them•Many opportunities open when you embrace change

77

Things to forget

•First normal form•Waterfall model•Single server deployment•Single language skill•Build everything from scratch•Build custom infrastructure

78

Things to learn

•Agile•Take risks, fail often, fail fast and learn•API Design: create the API first•UI Design, Javacript, HTML5, CSS3•A/B Testing•Open Source, Open Standards•Architecture, Distributed Computing (CAP theorem, 8 fallacies)•Cloud Platforms and APIs•Multiple types of languages (imperative, object, functional, logic)•Ability to encapsulate domain knowledge in a DSL•Build on the shoulders of giants: reuse, REST APIs•Pick your battles, choose what you need to build yourself to add value •Learn to live in a box (embrace platform limitations) to think outside the box•Use an App Store for distribution
