Platform as a Service (PaaS) Landscape
Brightcove’s Media PaaS
The Making of a Platform with Adobe Technology
Q + A

Platform as a Service (PaaS) Landscape
Defining “Platform as a Service”
PaaS: What, where and how

Defining “Platform as a Service”

Services through Cloud Computing
Consume broad range of services on demand
No Software or Servers!
Easy to scale with infrastructure in the cloud
Dynamically adapt compute power
Take advantage of utility metered models
Tap into operational excellence and economies of scale

Three Broad Categories
Infrastructure
Amazon EC2/S3, Google AppEngine, Sun Grid, 3Tera, IBM Blue Cloud
Software
Brightcove, Salesforce, NetSuite, Omniture, Ning, SpringCM
Platform
Brightcove, Salesforce, Ning, LongJump, Intuit QuickBase, Bungee Labs Connect

Platform Defined
A "platform" is an expressive medium.
Many existing platforms: Windows, SymbianOS, Flex
Ability to build and create
Platform as a Service
Create, consume, deploy and run in “the cloud”

PaaS: What, where and how

PaaS: What
Problem, what problem?
Targeted capabilities
Example: Consumer Platform
Backend Applications
Fast, sexy UIs
Tap into Internet fabric
Analytics/Reporting

PaaS: Where
Marc Andreessen Blog
Access API: Flickr, yelp.
Plug-in API: Facebook, MySpace
Runtime Environment: BungeeConnect

PaaS: How
How can we build and create?
Different types of developers
Need a blend of tools

Brightcove’s Media PaaS – the “How”

Media PaaS – the “How”
Templating WYSIWYG Tool
Web service APIs
Runtime Engine, Player APIs

Templating Usage
WYSIWYG Interface
Control colors, styles, themes and policies
Fast, easy, custom!

Stats
Process & Team Organization
Infrastructure and Architecture
The Making of a Platform with Adobe Technology

Stats
135 Million Unique Users/month (as of 6 – 9 months ago)
~2 billion server transactions/month
1.5 Petabytes (1,500,000 GBs) of media delivered/month
Thousands of platform users, hundreds of major media brands, 50 television networks, newspaper and magazine publishers, and all the major record labels in the US

Process & Team Organization

Process
We use the Scrum Methodology
Month long sprints
2x2 major release schedule
Cross-functional team, 4 – 9 people
Stand-up, user stories, story points, PO, burndown, retrospective
Operate 10 teams across 3 geographies

Process
Common language across the entire organization.
Adapt to changing market
Deep collaboration
It’s a marathon, not a sprint!

Infrastructure and Architecture

Brightcove’s Applications © 2006 Brightcove, Inc. All rights reserved. Company Confidential. Server Consumer Players Business Applications Media Publishing Ads Video Player Photo Player Server Server Server Server Server Server Server

Adobe Technology Used
ActionScript 2, ActionScript 3
Flex 1.5, Flex 2
AMF 0 (OpenAMF), AMF 3 (BlazeDS)
FMS 2.1, FMS 3.0
FlexBuilder

Consumer Video Player Technology
ActionScript 3, AVM2
AMF3 as client/server communication protocol
~70K LOC written
FlexBuilder as IDE/Developer Tool
Migrated from AS2 Players

Challenges
Speed + Dynamic Experience
Dynamic delivery of media

Speed + Dynamic Experience
AVM2 (97% penetration)
Partition into libraries (~50% savings)
Obfuscation/minification
Consumer client load vs. business application load
© 2006 Brightcove, Inc. All rights reserved. Company Confidential. Load Time in MS SWF Size in KB No Modules 341K Player Load 169K Menu 34K Overlay Controls 40K Volume Controls 16K Ad Support 45K

Speed + Dynamic Experience continued….
Client/Server communication
Think about how to organize server calls
Think about wire protocol
Getters vs. e4x, 13x faster access
AMF Open specification; JMeter and other applications

Dynamic Delivery of Media
Personalized underwear but not media?!
Media files are BIG!
PD vs. Streaming for video delivery

Business Applications Technology
Flex 2, AVM2
Flex vs. ActionScript vs. DHTML
AMF3 as client/server communication protocol
Cairngorm as micro-architecture
~100K LOC written, 150 Commands
FlexBuilder as IDE/Developer Tool
FlexUnit for unit testing
Homegrown integration tool

Challenges
Development process
Fast UI Responses

Development process – skills and workflow
Not enough Flex people! Training Java people.
Work across technology lines
Strong emphasis on design; auto-generate SWCs

Development process – code layout © 2006 Brightcove, Inc. All rights reserved. Company Confidential. Common (Shared UI + Classes) Services (Server Integration) Parts (Cairngorm Specifics) Ad Application Publishing Application Media Application

Development process – code layout
Each project contains own set of unit tests
Shared project layers are compiled as SWC, enables faster compile
Each project checks in .project, .actionScriptProperties and .flexProperties file

Fast UI Responses
AVM2
How to get Data?
Structure server API; initial view, lazy load, different types of DTOs
Make clients intelligent about their needs
Datagrid presentation strategies

Server Technology Overview
Java 6, 64 bit JVM
Tomcat, Spring, Hibernate and Coherence
BlazeDS as AMF gateway
~350K LOC
JUnit, JMeter, Lunt
Eclipse IDE, Emacs, Vi

Challenges
Low latency, high throughput
Better user experience
Minimize capex, Facebook was rumored to have raised 100M to buy 50K servers. That’s a lot of dough!
Scale

Summary
Understand PaaS and how to evaluate
Case study of a successful company built on Adobe Platform
Great platforms enable great applications - Go forth and create!
