A guest lecture I gave on 06th June 2014 at HS Rapperswil about why and how we develop for the cloud and in the cloud - and how we at IBM see it. Topics covered are general motivation, Eclipse Orion, IBM JazzHub/devOps services, Cloud Foundry and IBM BlueMix.

1. Software Development

2. Welcome to...

5. 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

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

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

8. We like what we're doing

9. PAST (sort of)

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

11. 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

12. Productivity ?
Moore's Law does not apply to Software

13. Innovation ?

14. Quality ?
Development != Delivery

15. What we mean by "devOps"
first principle of the "Agile Manifesto"

16. IBM Vision

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

18. Raising Levels of Abstraction
<
<<

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

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

21. 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)

22. 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)

23. Develop

24. Cloud, Anyone ?

25. 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
http://www.cloudcomputingpatterns.org/Private_Cloud

26. Eclipse Orion
http://eclipse.org/orion

27. Code Anywhere

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

29. 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).

30. 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();

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

32. Node.js based Server
Single user
portable
high performance
some limitations
> npm install orion
> npm start orion
(goto http://localhost:8081)

33. 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 ...

34. 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)

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

36. DEMO

37. JazzHub and IBM DevOps Services

Connect to processes on service Nodes
Cloud Pattern: Integration Provider,
Application Component Proxy
>

56. BOSH
Provision, deploy and manage the PaaS Platform Runtime
Independent of Hypervisors / IaaS

(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.
