The Enterprise Ecosystem, Part I
What actually is an Enterprise?
• Commonly used word to explain commonly encountered
problems
– Often heterogeneous and varied
– Multiple demands from multiple units
• Only one thing doesn’t change: having changes
• But what environment isn’t like this?

The Enterprise Ecosystem, Part IA
A Case Study
• Major medical institute in New York City
– Thick-client desktop application from third-party
– Oracle backend
– Critical medical data under HIPAA regulation
– Over 100 clinic operations
– Thousands of patients seen daily
– Ongoing changing requirements from various units

What Existed
… and what didn’t
• Custom LAMP intranet
– Unique reporting not available from any other system
– Unique functionality, not possible through a out-of-box solution
– Multiple developers over 9 years – very messy code base
– Financially, medically and compliance critical
– MySQL intermediary data store
• No version control
• No framework
– No modular code or SQL usage!
• No coding standards
• No previous good developers

The Enterprise Ecosystem, Part II
Enterprise Ready = Dealing with a Mess
• Business Requirement:
Move to Microsoft SQL Server in three months
• Repercussions for 9 year old PHP codebase
– Migrate to Windows and IIS
– Convert database interaction from OCI to MSSQL
– Rewrite ALL SQL
– Keep service online – continue to manage change requests
• Other requirements
– “We might change our mind and go back to Oracle afterwards”
Seriously?

Why PHP?
Why it was Chosen Originally – The *ility Slide
• Agility
– Intranets need to be very adaptable and support frequent internal
change requests
– Integrate with MySQL, Oracle and third-part scheduling systems
• Stability
– Able to handle internal traffic on minimal hardware
– Active broad based development from around the world
– Initially not considered mission-critical – of course!
• Flexibility
– Custom extensions could be developed
– Could run on web or as CLI (used for scheduled/cron tasks)

Why PHP?
Why it was Chosen Originally – The Glue Slide
• Fundamental Enterprise Requirement
Connectivity
Connecting and enabling multiple “things”
• Extensions developed by the PHP Group and open
source community
– Multiple databases
– Image processing, XML
– Web services and ColdFusion integration
– FTP, Windows share
Even Years Ago, PHP was Unique

Why PHP?
Why not?
• Years later, PHP continues to rock…
– It was a boon that we had chosen it
– Now, nothing else would make sense
• Corporate support from Oracle
– Did I mention we had to upgrade from Oracle 8 to 9 in the
interim?
– Excellent database driver support
• Corporate support from Microsoft
– Native support for Windows Server, IIS
– Used Web Platform Installer which was basically plug-n-play
– SQL Server native driver now available

Migrate, Migrate, Migrate
How it Went Down
• Utilized in-house cross-platform framework (NAS)
– Runs transparently on Windows, Linux
– Run same code on web server or command line
• Utilized AMP (Apache/MySQL/PHP)
– Cross-platform could adapt to changing environments
– Facilitate migration by allowing two simultaneous intranets to run
• Migration Vectors
1. Converted legacy code to NAS
2. Imported into Subversion
3. Deployed to Windows
4. Fine tuned for changing from Apache to IIS
5. Framework drivers for Oracle/MSSQL to enable switch

Conclusions
The Internet Speaks PHP – Speak to It
• PHP enables an enterprise – to be an enterprise
• PHP can hold an enterprise together
• The greatest enterprise – the internet
• We’ll see great strides in connecting different resources
• Creation of Web 3.0, social networks, and the semantic web
– At the forefront of enabling the internet as an enterprise
• Web service and API support
• Available as an invaluable tool from the open source community
