Patterns give us a common language to
describe repeatable solutions
>> Architectural Patterns
.. Similar solutions to the same problem
>> Usage patterns
.. Universal usage scenarios
>> Implementation patterns
.. PSO Experience (formal/informal)
.. Productized solutions

>> Fried >> Baked

Caching strategies
>> Data caching
.. Read-optimized repository
.. Object caching
>> Page caching
.. Fragment caching
.. Full page caching OSCache
.. Reverse proxy
>> Site caching
.. Spider
.. Static deploy GNU WGet

Baking style: Adding logic

Code publishing (parbaked)
>>Strategy:
Use the CMS to publish
unexecuted scripting code
to an active delivery tier
>>Advantages
.. Good for small touches of
dynamism with “Model 1”
architectures
.. Choose your own scripting
language
>>Disadvantages:
.. Breaks “MVC” because model
is baked into the view
.. Deployment issues on Java.
Better for .NET and PHP
based delivery tiers.

18. < C O N T E N T H E R E />
Dynamic client
>> Strategy:
Statically publish content
and use Javascript on the
client to add dynamism
>> Advantages
.. Minimal disruption to
static publishing system
.. Lightweight integration
across multiple systems
>> Disadvantages:
.. Security can be a problem
.. SEO issues
.. Accessibility issues
.. Browser compatibility
10/09/2007 © Copyright 2008 Content Here. 18

19. < C O N T E N T H E R E />
Fragment publishing
>> Strategy:
Use the CMS to publish HTML
fragments that can be
assembled by a dynamic web
application
>> Advantages
.. Good for static blocks like
headers, footers, and
“about pages”
.. Works well with portals
>> Disadvantages:
.. Preview issues
.. Fragments are static
.. Access control issues

20. < C O N T E N T H E R E />
Structured publishing
>> Strategy:
Use the CMS to publish
structured content into a
dynamic web application
>> Advantages
.. Maximum flexibility on the
delivery tier
.. Maximum de-coupling:
“Separation of Concerns.”
>> Disadvantages:
.. Need to have a data driven
delivery tier
.. Preview is often
problematic

Summary
>> Different CMS architectures come with native strengths and
weaknesses
>> With patterns, you can transform your CMS
.. Feed your content into a dynamic presentation layer
.. “Re-heat” your pre-fried content
