Development in the cloud for the cloud

Agenda
Software runs the world
What do we mean by "devOps" ?
Develop: Eclipse Orion and IBM JazzHub
Run: Cloud Foundry and IBM BlueMix
Deliver: a continuous delivery pipeline
Call to Action

Software runs the world
We're in a 303.8 billion $ industry

New Business Models
Traveling Salesman
http://xkcd.com/399/

TODAY
>> we need new different practices, platforms and tools

New Challenges
Productivity
Time to market, the Lean Enterprise, devOps, MTBF vs. MTTR
Innovation
Design Thinking, User Experience (UX), disruptive technology (CAMS, IoT)...
Quality
continuous delivery, automation, standardized platforms

Productivity ?
Moore's Law does not apply to Software

Quality ?

Development != Delivery

What we mean by "devOps"

first principle of the "Agile Manifesto"

Cloud to the rescue ?

Cloud Service Models can help...
reduce administrative burden of technology stacks
Streamline & standardize delivery processes
shorten delivery & feedback cycles

Raising Levels of Abstraction

Taxonomy
http://www.cloudcomputingpatterns.org/
A Pattern language for solutions for designing, building & managing Cloud applications

Dan Berg: Adopting a devOps approach with cloud
http://youtu.be/fVaJigwfNY4

Pattern: PaaS
Providers share IT resources providing an application
hosting environment between customers to enable self-
service, rapid elasticity, and pay-per-use pricing.
http://www.cloudcomputingpatterns.org/Platform_as_a_Service_(PaaS)

Pattern: SaaS

Providers share IT resources providing human-usable
application software between customers to enable self-
service, rapid elasticity, and pay-per-use pricing.
http://www.cloudcomputingpatterns.org/Software_as_a_Service_(SaaS)

What About Private Clouds ?
Better utilization of corporate data centers
(outsourcing, "follow the sun development" etc.)
Improved time to market
Reduce administration burden
(e.g. workstation provisioning & patching)
Multi-tenant models for different business units
Frictionless application lifecycle management

Eclipse Orion

http://eclipse.org/orion

Orion Architecture
http://wiki.eclipse.org/Orion/Documentation/Developer_Guide/Architecture

Orion Architecture (2)
1. Browser client / remote data. This is a pure web model. A browser-based
client using Orion JavaScript client libraries and accessing remote Orion
services via REST API.
2. Mixed client / local data. A rich client (traditional Eclipse client), which contains
a mixture of "legacy" components written in Java and web components
written in JavaScript. The JavaScript components interact with JavaScript
libraries and/or REST APIs, while Java components interact with the Eclipse
Platform Java APIs.
3. Rich client / remote data. Traditional Eclipse client components interacting
with remote Orion services via REST API. This enables a mixture of rich client
and browser-based tools to inter-operate against the same server-side data.
4. Remote client / remote data. Server side tools written in Java, accessing local
Orion services (for example a build server working against an Orion
workspace server on the same machine).

Client Architecture
JavaScript Modules (CommonJS, AMD)
Plugins and Services
"Hollywood Principle"
Promises (= escape from callback hell)
var provider = new orion.PluginProvider();
var serviceImpl = {
run : function(text) {
return text.toUpperCase();
}
};
var serviceProps = {
name : "UPPERCASE",
img : "/images/gear.gif",
key : [ "u", true ]
};
provider.registerService("orion.edit.command", serviceImpl, serviceProps);
provider.connect();

Equinox-based Server
Java (OSGi)
Multi user
re-use existing Eclipse 3.x plugins,
expose through REST interfaces to Orion client

Node.js based Server

Single user
portable
high performance
some limitations
> npm install orion
> npm start orion
(goto http://localhost:8081)

Community and Ecosystem
VMware - Main contributor to "Scripted"
Firefox - embeds Orion for scratchpad & debug tools
e(fx)clipse - JavaFX, OSGi, Eclipse and Orion
Maqetta - Orion core and file system
Pivotal, HP, SAP ...

Scripted - Editor component

https://github.com/scripted-editor/scripted
> npm install -g https://github.com/scripted-editor/scripted/tarball/dev
[..] // ^ as of 2014-05-02: had error in main branch
> scr foobar.js
(project root for indexing etc: looks for nearest .git/.scripted file)

Scripted - Key Features
Written in & focus on HTML5, CSS, JavaScript
Very lightweight
JSHint, Content assist, key bindings ...

JazzHub and IBM DevOps Services
based on Eclipse Orion
Free(*) & Open
Integration with GitHub, Git and Jazz SCM
Team Code Collaboration
Agile Planning & Tracking
Different Clients (Eclipse, CLI, Web IDE)

(*) public projects, private projects free during
beta
Pattern: SaaS

Cloud Foundry

http://cloudfoundry.org
Supporters include IBM, VMware, Pivotal, SAP, Rackspace, Intel,
SwissCom etc...

Domain Meta-Model

http://www.slideshare.net/rajdeep/cloudfoundry-rajdeep-nov2013

Component Overview

Source: Pivotal - Cloud Foundry Technical Overview

Cloud Controller

Interfaces with clients (cf, Eclipse ...)
Account management
provisioning control
REST API to domain model
Cloud Pattern: Managed Configuration
<

NATS

Internal Message Bus
Optimized for fast communication
Cloud Pattern:
Message-oriented middleware
<

DEA

Droplet Execution Agent
Fully isolated containers
(Warden, Linux VM)
Manages App lifecycles
Buildpacks create droplets
that execute on a DEA
Cloud Pattern: Multi Component Image,
Tenant-isolated Component
<
<

Router

Shape & Route all traffic
dynamic routing table for load balancing
Cloud Pattern: Virtual Networking

<

Health Manager

Monitors app state (current DEA vs. expected CC)
Notify Controller on mismatch (propose action)
Cloud Pattern: Watchdog

<

Service Broker

Gateway to external services (e.g. from Marketplace)
Connect to processes on service Nodes
Cloud Pattern: Integration Provider,
Application Component Proxy

>

BOSH

Provision, deploy and manage the PaaS Platform Runtime
Independent of Hypervisors / IaaS
supports e.g. OpenStack, IBM SoftLayer, vFabric ...
Cloud Patterns: a lot :)
>

IBM BlueMix (beta)
http://bluemix.net
Management Dashboard
Marketplace (free / commercial)
Runtimes
Boilerplates
Services
...

Example: Java Liberty Proﬁle

Backend Integration
(Hybrid Backend)
Backend functionality comprised of data intensive
processing and data storage is experiencing varying
workloads and is hosted in an elastic cloud while the rest of
an application is hosted in a static data center.
